Description

ブレーキ装置Brake device
　この発明は、ブレーキディスクに制動力を与えることにより回転軸の回転を制動するブレーキ装置に関するものである。 The present invention relates to a brake device that brakes rotation of a rotary shaft by applying a braking force to a brake disc.
　従来、回転軸に設けられたスプライン部にブレーキディスクのボス部をスライド可能に取り付け、ブレーキディスクにブレーキライニングを介してアマチュアを押圧することによりブレーキディスクに制動力を与えるようにしたエレベータ用巻上機のブレーキが知られている。このような従来のエレベータ用巻上機のブレーキでは、ブレーキディスクのボス部にブレーキライニングの摩耗粉を受ける受け部が設けられている（例えば特許文献１参照）。 Conventionally, an elevator hoisting device in which a boss portion of a brake disc is slidably attached to a spline portion provided on a rotating shaft and a braking force is applied to the brake disc by pressing an armature on the brake disc via a brake lining. Machine brakes are known. In such a conventional elevator hoist brake, a boss portion of a brake disk is provided with a receiving portion for receiving brake lining wear powder (see, for example, Patent Document 1).
特開２００４－２２４５５２号公報JP 2004-224552 A
　回転軸のスプライン部に異物が付着したままブレーキを使用すると、ブレーキディスクがスプライン部に対してスライドしにくくなり、ブレーキディスクとブレーキライニングとが互いに接触したままブレーキディスクが回転することになる。これにより、例えばブレーキライニングの異常摩耗及び摺動音の発生等の不具合がブレーキに生じてしまう。 If the brake is used with foreign matter adhering to the spline part of the rotating shaft, the brake disk will not slide easily against the spline part, and the brake disk will rotate while the brake disk and brake lining are in contact with each other. As a result, troubles such as abnormal wear of the brake lining and generation of sliding noise occur in the brake.
　特許文献１に示されている従来のエレベータ用巻上機のブレーキでは、スプライン部に対する異物の付着を受け部によって抑制することができるが、スプライン部に対する異物の付着を完全に防止することはできない。従って、特許文献１に示されている従来のエレベータ用巻上機のブレーキでも、上記のような不具合の発生を防止するために、スプライン部を清掃してスプライン部から異物を除去する必要がある。しかし、特許文献１に示されている従来のエレベータ用巻上機のブレーキでは、スプライン部を清掃するためにブレーキを分解しなければならず、ブレーキの分解及び組立に手間がかかってしまい、ブレーキのメンテナンス作業に手間がかかってしまう。 In the brake of the conventional elevator hoist shown in Patent Document 1, foreign matter adhesion to the spline portion can be suppressed by the receiving portion, but foreign matter adhesion to the spline portion cannot be completely prevented. . Therefore, even in the brake of the conventional elevator hoist shown in Patent Document 1, it is necessary to clean the spline part and remove foreign matters from the spline part in order to prevent the occurrence of the above-described problems. .

FIG. 3 is a longitudinal sectional view showing the brake device 7 when the braking force applied to the rotating shaft 15 in FIG. 2 is released. FIG. 2 shows the brake device 7 when the braking force for the rotating shaft 15 is generated. The brake device 7 is supported by the hoisting machine body 5. The brake device 7 brakes the drive sheave 6 by applying a braking force to the rotating shaft 15 of the motor in the hoisting machine body 5.
　ブレーキ装置７は、巻上機本体５のケーシングと一体になっている第１の固定部材であるブレーキ支持部材２１と、ブレーキ支持部材２１に固定されているロッド２２と、ブレーキ支持部材２１にロッド２２を固定する締結具である固定ナット２３と、ロッド２２に設けられ、回転軸１５の軸線方向についてブレーキ支持部材２１から離れた位置に配置されている第２の固定部材であるエンドプレート２４と、ブレーキ支持部材２１とエンドプレート２４との間に配置されているスライド被押圧体２５と、ロッド２２にスライド可能に設けられ、ブレーキ支持部材２１とスライド被押圧体２５との間に配置されているアマチュア２６と、エンドプレート２４に向けてアマチュア２６を付勢する付勢体である制動ばね２７と、制動ばね２７の付勢力に逆らってブレーキ支持部材２１に近づく方向へアマチュア２６を変位させる電磁コイル２８とを有している。 The brake device 7 includes a brake support member 21 that is a first fixing member integrated with a casing of the hoisting machine body 5, a rod 22 that is fixed to the brake support member 21, and a rod that is attached to the brake support member 21. A fixing nut 23 that is a fastener for fixing 22, an end plate 24 that is provided on the rod 22, and is a second fixing member that is disposed at a position away from the brake support member 21 in the axial direction of the rotary shaft 15; The slide pressed body 25 disposed between the brake support member 21 and the end plate 24 and the rod 22 are slidably provided, and are disposed between the brake support member 21 and the slide pressed body 25. An armature 26, a braking spring 27 that is an urging body that urges the armature 26 toward the end plate 24, And an electromagnetic coil 28 that displaces the armature 26 in a direction approaching the brake support member 21 against the force.
　ブレーキ支持部材２１には、ロッド通し穴２９が回転軸１５の軸線方向に沿って設けられている。ロッド通し穴２９は、ロッド通し穴２９の深さ方向に沿った大径穴２９１と、大径穴２９１からロッド通し穴２９の深さ方向へ連続する小径穴２９２とを有している。大径穴２９１の内径は、小径穴２９２の内径よりも大きくなっている。これにより、大径穴２９１と小径穴２９２との境界には、穴側段差部２９３が形成されている。 The brake support member 21 is provided with a rod through hole 29 along the axial direction of the rotary shaft 15. The rod through hole 29 has a large diameter hole 291 along the depth direction of the rod through hole 29 and a small diameter hole 292 continuous from the large diameter hole 291 in the depth direction of the rod through hole 29. The inner diameter of the large diameter hole 291 is larger than the inner diameter of the small diameter hole 292. Thereby, a hole-side step 293 is formed at the boundary between the large-diameter hole 291 and the small-diameter hole 292.
　ロッド２２は、第１のロッド部２２１と、第１のロッド部２２１の一端部から第１のロッド部２２１の軸線方向へ延びている第２のロッド部２２２とを有している。第１のロッド部２２１の他端部は、ロッドねじ部２２１ａになっている。 The rod 22 includes a first rod portion 221 and a second rod portion 222 extending from one end portion of the first rod portion 221 in the axial direction of the first rod portion 221. The other end portion of the first rod portion 221 is a rod screw portion 221a.
　第１のロッド部２２１の外径は、第２のロッド部２２２の外径よりも大きくなっている。これにより、第１のロッド部２２１と第２のロッド部２２２との境界には、ロッド側段差部２２３が形成されている。第２のロッド部２２２は、ねじ部になっている。 The outer diameter of the first rod part 221 is larger than the outer diameter of the second rod part 222. Thereby, a rod-side step 223 is formed at the boundary between the first rod part 221 and the second rod part 222. The second rod portion 222 is a screw portion.
　ロッド２２は、第１のロッド部２２１の一部と、第２のロッド部２２２の一部とをブレーキ支持部材２１の両側から突出させた状態で、ロッド通し穴２９に通されている。これにより、ロッド２２は、回転軸１５の軸線方向に沿ってブレーキ支持部材２１を貫通している。また、ロッド２２は、ロッド側段差部２２３を穴側段差部２９３に接触させた状態で、ブレーキ支持部材２１に固定されている。回転軸１５の軸線方向についてのブレーキ支持部材２１に対するロッド２２の位置決めは、ロッド側段差部２２３が穴側段差部２９３に接触することにより行われている。 The rod 22 is passed through the rod through hole 29 with a part of the first rod part 221 and a part of the second rod part 222 protruding from both sides of the brake support member 21. Thereby, the rod 22 penetrates the brake support member 21 along the axial direction of the rotating shaft 15. The rod 22 is fixed to the brake support member 21 in a state where the rod-side step 223 is in contact with the hole-side step 293. Positioning of the rod 22 with respect to the brake support member 21 in the axial direction of the rotating shaft 15 is performed by the rod-side step portion 223 contacting the hole-side step portion 293.
　固定ナット２３は、ねじ部である第２のロッド部２２２に嵌められている。また、固定ナット２３は、ロッド側段差部２２３を穴側段差部２９３に押し付ける方向へブレーキ支持部材２１に対して締め込むことにより、ロッド２２をブレーキ支持部材２１に固定している。 The fixing nut 23 is fitted into the second rod portion 222 which is a screw portion. The fixing nut 23 fixes the rod 22 to the brake support member 21 by tightening the rod side step 223 with respect to the brake support member 21 in a direction in which the rod side step 223 is pressed against the hole side step 293.
　第１のロッド部２２１のロッドねじ部２２１ａには、一対の調整ナット３０が嵌められている。エンドプレート２４は、一対の調整ナット３０の間で締め付けられることにより第１のロッドねじ部２２１ａに固定されている。ロッド２２に対するエンドプレート２４の位置は、第１のロッドねじ部２２１ａに対する一対の調整ナット３０の位置を調整することにより、ロッド２２の軸線方向について調整可能になっている。 A pair of adjustment nuts 30 are fitted to the rod screw portion 221a of the first rod portion 221. The end plate 24 is fixed to the first rod screw portion 221a by being tightened between the pair of adjustment nuts 30. The position of the end plate 24 with respect to the rod 22 can be adjusted in the axial direction of the rod 22 by adjusting the position of the pair of adjusting nuts 30 with respect to the first rod screw portion 221a.
　スライド被押圧体２５は、複数のブレーキディスク２５１と、複数のブレーキディスク２５１の間に配置されている中間スライド部材である中間プレート２５２とを有している。この例では、ブレーキディスク２５１の数が２個、中間プレート２５２の数が１個になっている。 The slide pressed body 25 includes a plurality of brake disks 251 and an intermediate plate 252 that is an intermediate slide member disposed between the plurality of brake disks 251. In this example, the number of brake disks 251 is two and the number of intermediate plates 252 is one.
　回転軸１５は、各ブレーキディスク２５１の中央部を貫通している。回転軸１５の外周部には、スプライン部１５１が回転軸１５の軸線方向に沿って設けられている。各ブレーキディスク２５１は、スプライン結合によってスプライン部１５１に設けられている。即ち、各ブレーキディスク２５１は、スプライン部１５１に対して回転軸１５の軸線方向へスライド可能で、かつスプライン部１５１に対する回転軸１５の周方向への変位が阻止された状態で、スプライン部１５１に設けられている。これにより、各ブレーキディスク２５１は、回転軸１５と一体に回転する。 The rotary shaft 15 passes through the center of each brake disk 251. A spline portion 151 is provided along the axial direction of the rotating shaft 15 on the outer peripheral portion of the rotating shaft 15. Each brake disk 251 is provided in the spline part 151 by spline coupling. That is, each brake disk 251 is slidable in the axial direction of the rotary shaft 15 with respect to the spline portion 151, and in the state where displacement of the rotary shaft 15 in the circumferential direction with respect to the spline portion 151 is prevented, Is provided. Thereby, each brake disk 251 rotates integrally with the rotating shaft 15.
　中間プレート２５２は、第１のロッド部２２１にスライド可能に設けられている。これにより、中間プレート２５２は、ロッド２２の軸線方向へロッド２２に対して変位可能になっている。また、中間プレート２５２の周方向への回転は、ロッド２２によって阻止されている。 The intermediate plate 252 is slidably provided on the first rod portion 221. Thereby, the intermediate plate 252 can be displaced with respect to the rod 22 in the axial direction of the rod 22. Further, the rotation of the intermediate plate 252 in the circumferential direction is blocked by the rod 22.
　アマチュア２６は、第１のロッド部２２１にスライド可能に設けられている。これにより、アマチュア２６は、ロッド２２の軸線方向へロッド２２に対して変位可能になっている。また、アマチュア２６の周方向への回転は、ロッド２２によって阻止されている。 The amateur 26 is slidably provided on the first rod portion 221. Thereby, the armature 26 can be displaced with respect to the rod 22 in the axial direction of the rod 22. The rotation of the armature 26 in the circumferential direction is blocked by the rod 22.
　アマチュア２６、中間プレート２５２及びエンドプレート２４のそれぞれには、制動部材であるブレーキライニング３２が設けられている。ブレーキライニング３２は、アマチュア２６とブレーキディスク２５１との間、ブレーキディスク２５１と中間プレート２５２との間、及びブレーキディスク２５１とエンドプレート２４との間のそれぞれに配置されている。 Each of the amateur 26, the intermediate plate 252 and the end plate 24 is provided with a brake lining 32 which is a braking member. The brake lining 32 is disposed between the amateur 26 and the brake disk 251, between the brake disk 251 and the intermediate plate 252, and between the brake disk 251 and the end plate 24.
　アマチュア２６は、スライド被押圧体２５をエンドプレート２４に押圧する図３に示す制動位置と、制動位置よりもブレーキ支持部材２１に近い図２に示す解除位置との間で変位可能になっている。 The amateur 26 can be displaced between a braking position shown in FIG. 3 that presses the slide pressed body 25 against the end plate 24 and a release position shown in FIG. 2 that is closer to the brake support member 21 than the braking position. .
　アマチュア２６が制動位置にあるときには、アマチュア２６とブレーキディスク２５１との間、ブレーキディスク２５１と中間プレート２５２との間、及びブレーキディスク２５１とエンドプレート２４との間のそれぞれにブレーキライニング３２が介在した状態で、スライド被押圧体２５がエンドプレート２４に押圧される。スライド被押圧体２５がエンドプレート２４に押圧されている状態では、各ブレーキライニング３２がブレーキディスク２５１に接触する。即ち、スライド被押圧体２５がエンドプレート２４に押圧されると、各ブレーキディスク２５１がブレーキライニング３２で両側から挟圧される。これにより、各ブレーキディスク２５１及び回転軸１５に制動力が与えられる。 When the amateur 26 is in the braking position, the brake lining 32 is interposed between the amateur 26 and the brake disc 251, between the brake disc 251 and the intermediate plate 252, and between the brake disc 251 and the end plate 24. In this state, the slide pressed body 25 is pressed against the end plate 24. In a state where the slide pressed body 25 is pressed against the end plate 24, each brake lining 32 contacts the brake disc 251. That is, when the slide pressed body 25 is pressed against the end plate 24, each brake disk 251 is clamped from both sides by the brake lining 32. As a result, a braking force is applied to each brake disk 251 and the rotating shaft 15.
　アマチュア２６が解除位置にあるときには、スライド被押圧体２５がエンドプレート２４に押圧された状態が解除される。これにより、各ブレーキディスク２５１がスプライン部１５１に対してスライドするとともに中間プレート２５２が第１のロッド部２２１に対してスライドして、各ブレーキライニング３２が各ブレーキディスク２５１から離れる。各ブレーキライニング３２が各ブレーキディスク２５１から離れると、各ブレーキディスク２５１及び回転軸１５に対する制動力が解除される。 When the amateur 26 is in the release position, the state in which the slide pressed body 25 is pressed by the end plate 24 is released. Thereby, each brake disk 251 slides with respect to the spline part 151, and the intermediate plate 252 slides with respect to the first rod part 221, so that each brake lining 32 is separated from each brake disk 251. When each brake lining 32 is separated from each brake disk 251, the braking force on each brake disk 251 and the rotary shaft 15 is released.
　制動ばね２７は、ブレーキ支持部材２１とアマチュア２６との間に配置されている。ブレーキ支持部材２１には、制動ばね２７が配置された凹部３１が設けられている。制動ばね２７は、ブレーキ支持部材２１とアマチュア２６との間で縮められている。これにより、制動ばね２７は、ブレーキ支持部材２１とアマチュア２６とが互いに離れる方向へ弾性復元力を発生し、制動位置へアマチュア２６を付勢している。 The braking spring 27 is disposed between the brake support member 21 and the amateur 26. The brake support member 21 is provided with a recess 31 in which a brake spring 27 is disposed. The brake spring 27 is contracted between the brake support member 21 and the amateur 26. Accordingly, the brake spring 27 generates an elastic restoring force in a direction in which the brake support member 21 and the armature 26 are separated from each other, and urges the armature 26 to the brake position.
　電磁コイル２８は、ブレーキ支持部材２１に設けられている。また、電磁コイル２８は、電磁コイル２８への通電により、制動ばね２７の付勢力に逆らってアマチュア２６を吸引する電磁吸引力を発生する。アマチュア２６は、電磁コイル２８の電磁吸引力の発生により、制動ばね２７の付勢力に逆らって解除位置に変位される。 The electromagnetic coil 28 is provided on the brake support member 21. The electromagnetic coil 28 generates an electromagnetic attractive force that attracts the armature 26 against the urging force of the braking spring 27 by energizing the electromagnetic coil 28. The amateur 26 is displaced to the release position against the urging force of the brake spring 27 by the generation of the electromagnetic attractive force of the electromagnetic coil 28.
　スライド被押圧体２５は、アマチュア２６が制動位置にあるときに、図３に示すように、エンドプレート２４からブレーキ支持部材２１側に設定された設定範囲Ａに収まる。回転軸１５の軸線方向についての設定範囲Ａの寸法は、各ブレーキディスク２５１、中間プレート２５２及びブレーキライニング３２のそれぞれの厚さに基づいて設定されている。 When the armature 26 is in the braking position, the slide pressed body 25 is within the set range A set on the brake support member 21 side from the end plate 24 as shown in FIG. The dimension of the setting range A in the axial direction of the rotary shaft 15 is set based on the thickness of each brake disk 251, intermediate plate 252, and brake lining 32.
　第２のロッド部２２２におけるブレーキ支持部材２１から突出している部分の長さＬ１は、設定範囲Ａの寸法よりも長くなっている。また、スプライン部１５１は、図３に示すように、設定範囲Ａからブレーキ支持部材２１側とは反対側へ延長されている。スプライン部１５１における設定範囲Ａから延長されている部分の長さＬ２は、設定範囲Ａの寸法以上の寸法になっている。 The length L1 of the portion protruding from the brake support member 21 in the second rod portion 222 is longer than the dimension of the setting range A. Moreover, the spline part 151 is extended from the setting range A to the opposite side to the brake support member 21 side, as shown in FIG. The length L2 of the part extended from the setting range A in the spline part 151 is a dimension larger than the dimension of the setting range A.
　各ブレーキディスク２５１の少なくともいずれかの内径部分には、スプライン部１５１に接触する清掃部材３３が設けられている。清掃部材３３は、スプライン部１５１に接触しながらスプライン部１５１に対して移動することにより、スプライン部１５１に付着した異物を除去する。この例では、２つのブレーキディスク２５１のうち、ブレーキ支持部材２１に近い一方のブレーキディスク２５１にのみ清掃部材３３が設けられている。清掃部材３３としては、例えば砥石、やすり又はブラシが用いられている。 At least one inner diameter portion of each brake disk 251 is provided with a cleaning member 33 that contacts the spline portion 151. The cleaning member 33 moves with respect to the spline part 151 while being in contact with the spline part 151, thereby removing foreign matters attached to the spline part 151. In this example, the cleaning member 33 is provided only on one of the two brake disks 251 that is close to the brake support member 21. As the cleaning member 33, for example, a grindstone, a file, or a brush is used.
　図４は、図３の清掃部材３３を示す拡大図である。また、図５は、図４のＶ－Ｖ線に沿った断面図である。清掃部材３３は、ブレーキディスク２５１の内面に形成されている凹部３４内に配置されている。凹部３４は、ブレーキディスク２５１の厚さ方向の中間部に設けられている。これにより、ブレーキディスク２５１の厚さ方向についての凹部３４の両側には、一対の側壁２５１ａが形成されている。また、清掃部材３３は、スプライン部１５１の溝部の底面に接触している。凹部３４の内面と清掃部材３３との間には、隙間が存在している。 FIG. 4 is an enlarged view showing the cleaning member 33 of FIG. FIG. 5 is a sectional view taken along line VV in FIG. The cleaning member 33 is disposed in a recess 34 formed on the inner surface of the brake disk 251. The concave portion 34 is provided at an intermediate portion in the thickness direction of the brake disk 251. Thus, a pair of side walls 251a are formed on both sides of the recess 34 in the thickness direction of the brake disk 251. Further, the cleaning member 33 is in contact with the bottom surface of the groove portion of the spline portion 151. There is a gap between the inner surface of the recess 34 and the cleaning member 33.
　清掃部材３３は、弾性体である押圧ばね３５を介してブレーキディスク２５１に取り付けられている。また、清掃部材３３は、押圧ばね３５の弾性復元力によってスプライン部１５１に押圧されている。なお、清掃部材３３は、弾性体であるゴムを介してブレーキディスク２５１に取り付けられていてもよい。 The cleaning member 33 is attached to the brake disc 251 via a pressing spring 35 that is an elastic body. The cleaning member 33 is pressed against the spline part 151 by the elastic restoring force of the pressing spring 35. The cleaning member 33 may be attached to the brake disc 251 via rubber that is an elastic body.
　次に、ブレーキ装置７の動作について説明する。例えばかご２が乗場階に停止している状態では、電磁コイル２８への通電が停止されている。このときには、制動ばね２７の付勢力によってアマチュア２６が制動位置に達している。これにより、図３に示すように、アマチュア２６とブレーキディスク２５１との間、ブレーキディスク２５１と中間プレート２５２との間、及びブレーキディスク２５１とエンドプレート２４との間のそれぞれにブレーキライニング３２が介在した状態で、スライド被押圧体２５がエンドプレート２４に押圧されている。従って、このときには、各ブレーキディスク２５１がブレーキライニング３２で挟圧され、各ブレーキディスク２５１及び回転軸１５に制動力が与えられている。 Next, the operation of the brake device 7 will be described. For example, when the car 2 is stopped on the landing floor, the energization of the electromagnetic coil 28 is stopped. At this time, the armature 26 has reached the braking position by the urging force of the braking spring 27. As a result, as shown in FIG. 3, the brake lining 32 is interposed between the armature 26 and the brake disk 251, between the brake disk 251 and the intermediate plate 252, and between the brake disk 251 and the end plate 24. In this state, the slide pressed body 25 is pressed against the end plate 24. Accordingly, at this time, each brake disk 251 is pinched by the brake lining 32, and a braking force is applied to each brake disk 251 and the rotating shaft 15.
　例えばかご２の移動を開始するときには、ブレーキ装置７がブレーキ解放動作を行う。ブレーキ装置７がブレーキ解放動作を行うときには、電磁コイル２８への通電が行われる。これにより、電磁コイル２８が電磁吸引力を発生し、アマチュア２６が制動ばね２７の付勢力に逆らって制動位置から解除位置へ変位される。このとき、巻上機本体５のモータの駆動力により回転軸１５が回転し、各ブレーキディスク２５１が回転軸１５と一体に回転する。また、ブレーキディスク２５１の回転に伴ってブレーキディスク２５１がスプライン部１５１をスライドし、各ブレーキディスク２５１のそれぞれの位置が、図２に示すように、アマチュア２６と中間プレート２５２との間、及び中間プレート２５２とエンドプレート２４との間のそれぞれの中立位置になる。これにより、各ブレーキディスク２５１がブレーキライニング３２から離れ、各ブレーキディスク２５１及び回転軸１５に対する制動力が解除される。このときのスプライン部１５１に対するブレーキディスク２５１のスライド量は微小であり、清掃部材３３は、押圧ばね３５の弾性変形によってスプライン部１５１に対して移動しない。 For example, when the movement of the car 2 is started, the brake device 7 performs a brake releasing operation. When the brake device 7 performs the brake releasing operation, the electromagnetic coil 28 is energized. As a result, the electromagnetic coil 28 generates an electromagnetic attractive force, and the armature 26 is displaced from the braking position to the release position against the urging force of the braking spring 27. At this time, the rotating shaft 15 is rotated by the driving force of the motor of the hoisting machine body 5, and each brake disk 251 rotates integrally with the rotating shaft 15. Further, as the brake disk 251 rotates, the brake disk 251 slides on the spline portion 151, and each position of each brake disk 251 is between the armature 26 and the intermediate plate 252, as shown in FIG. Each neutral position is between the plate 252 and the end plate 24. Thereby, each brake disk 251 leaves | separates from the brake lining 32, and the braking force with respect to each brake disk 251 and the rotating shaft 15 is cancelled | released. The sliding amount of the brake disk 251 with respect to the spline part 151 at this time is very small, and the cleaning member 33 does not move relative to the spline part 151 due to elastic deformation of the pressing spring 35.
　ブレーキ装置７がブレーキ制動動作を行うときには、電磁コイル２８への通電が停止される。電磁コイル２８への通電が停止されると、制動ばね２７の付勢力によりアマチュア２６が解除位置から制動位置へ変位される。これにより、各ブレーキディスク２５１及び中間プレート２５２がエンドプレート２４に向けてスライドし、図３に示すように、スライド被押圧体２５がアマチュア２６によってエンドプレート２４に押圧される。これにより、各ブレーキディスク２５１がブレーキライニング３２で挟圧され、各ブレーキディスク２５１及び回転軸１５に制動力が与えられる。このときも、スプライン部１５１に対するブレーキディスク２５１のスライド量は微小であり、清掃部材３３は、押圧ばね３５の弾性変形によってスプライン部１５１に対して移動しない。 When the brake device 7 performs a brake braking operation, the energization of the electromagnetic coil 28 is stopped. When energization of the electromagnetic coil 28 is stopped, the armature 26 is displaced from the release position to the braking position by the biasing force of the braking spring 27. As a result, each brake disk 251 and the intermediate plate 252 slide toward the end plate 24, and the slide pressed body 25 is pressed against the end plate 24 by the armature 26 as shown in FIG. As a result, each brake disk 251 is clamped by the brake lining 32, and a braking force is applied to each brake disk 251 and the rotating shaft 15. Also at this time, the sliding amount of the brake disc 251 with respect to the spline part 151 is very small, and the cleaning member 33 does not move relative to the spline part 151 due to the elastic deformation of the pressing spring 35.
　ここで、ブレーキ装置７の使用を継続すると、回転軸１５に設けられているスプライン部１５１には、ブレーキライニング３２の摩耗粉等の異物が付着する。異物がスプライン部１５１に付着すると、各ブレーキディスク２５１がスプライン部１５１をスライドしにくくなり、ブレーキ装置７の動作に不具合が生じるおそれがある。従って、スプライン部１５１を定期的に清掃して、スプライン部１５１に付着した異物を除去する必要がある。 Here, if the use of the brake device 7 is continued, foreign matter such as abrasion powder of the brake lining 32 adheres to the spline portion 151 provided on the rotary shaft 15. If foreign matter adheres to the spline part 151, it becomes difficult for each brake disk 251 to slide on the spline part 151, and there is a possibility that a malfunction occurs in the operation of the brake device 7. Therefore, it is necessary to periodically clean the spline part 151 to remove foreign matter adhering to the spline part 151.
　次に、スプライン部１５１を清掃する方法について説明する。図６は、図２のスプライン部１５１を清掃しているときの状態を示す縦断面図である。スプライン部１５１を清掃するときには、まず、アマチュア２６を解除位置に変位させた状態で保持具４１をブレーキ支持部材２１及びアマチュア２６に嵌める。これにより、電磁コイル２８への通電を停止しても、アマチュア２６が解除位置に保持される。 Next, a method for cleaning the spline portion 151 will be described. FIG. 6 is a longitudinal sectional view showing a state when the spline portion 151 of FIG. 2 is being cleaned. When cleaning the spline portion 151, first, the holder 41 is fitted to the brake support member 21 and the armature 26 with the armature 26 being displaced to the release position. Thereby, even if the energization to the electromagnetic coil 28 is stopped, the armature 26 is held at the release position.
　この後、ロッド２２をブレーキ支持部材２１に固定している固定ナット２３を緩めた後、固定ナット２３を回しながら、第２のロッド部２２２の端部にまで固定ナット２３を第２のロッド部２２２に対して移動させる。このとき、固定ナット２３は第２のロッド部２２２から外さない。 Thereafter, after loosening the fixing nut 23 that fixes the rod 22 to the brake support member 21, the fixing nut 23 is turned to the end of the second rod portion 222 while turning the fixing nut 23. Move to 222. At this time, the fixing nut 23 is not removed from the second rod portion 222.
　この後、第２のロッド部２２２をブレーキ支持部材２１に押し込んでロッド２２をブレーキ支持部材２１に対して移動させる。これにより、ブレーキ支持部材２１から離れる方向へエンドプレート２４が変位され、エンドプレート２４とアマチュア２６との間の距離が拡大する。このとき、固定ナット２３が第２のロッド部２２２に取り付けられたままになっているので、ロッド２２がブレーキ支持部材２１から外れることはない。 Thereafter, the second rod portion 222 is pushed into the brake support member 21 to move the rod 22 relative to the brake support member 21. Thereby, the end plate 24 is displaced in the direction away from the brake support member 21, and the distance between the end plate 24 and the armature 26 is increased. At this time, since the fixing nut 23 remains attached to the second rod portion 222, the rod 22 does not come off from the brake support member 21.
　この後、各ブレーキディスク２５１及び中間プレート２５２をエンドプレート２４に向けて移動させる。これにより、ブレーキ装置７の通常使用時の各ブレーキディスク２５１の可動範囲Ｂから外れた位置、即ちスプライン部１５１における寸法Ｌ２の延長範囲内の位置へ各ブレーキディスク２５１及び中間プレート２５２が移動し、可動範囲Ｂではスプライン部１５１の全体が露出する。 Thereafter, each brake disk 251 and the intermediate plate 252 are moved toward the end plate 24. Thereby, each brake disk 251 and the intermediate plate 252 move to a position outside the movable range B of each brake disk 251 during normal use of the brake device 7, that is, to a position within the extension range of the dimension L2 in the spline portion 151. In the movable range B, the entire spline portion 151 is exposed.
　この後、清掃部材３３が設けられた一方のブレーキディスク２５１を可動範囲Ｂでスプライン部１５１に沿って移動させる。これにより、清掃部材３３がスプライン部１５１に接触しながら移動し、異物が清掃部材３３によってスプライン部１５１から除去される。このとき、清掃部材３３は、凹部３４の側壁２５１ａに押されながら移動する。なお、清掃部材３３の１回の移動で異物が除去しきれない場合は、清掃部材３３を複数回往復移動させることにより、スプライン部１５１から異物を除去する。 Thereafter, one brake disk 251 provided with the cleaning member 33 is moved along the spline portion 151 within the movable range B. As a result, the cleaning member 33 moves while contacting the spline portion 151, and the foreign matter is removed from the spline portion 151 by the cleaning member 33. At this time, the cleaning member 33 moves while being pushed by the side wall 251 a of the recess 34. In addition, when a foreign material cannot be removed by one movement of the cleaning member 33, the foreign material is removed from the spline part 151 by reciprocating the cleaning member 33 a plurality of times.
　スプライン部１５１から異物が除去された後、ロッド２２のロッド側段差部２２３がロッド通し穴２９の穴側段差部２９３に接触するまで、第１のロッド部２２１をブレーキ支持部材２１に対して押し込む。このとき、各ブレーキディスク２５１をスプライン部１５１にスライドさせながら、エンドプレート２４をブレーキ支持部材２１に近づける。ロッド側段差部２２３が穴側段差部２９３に接触すると、エンドプレート２４が元の位置に戻り、ブレーキ支持部材２１に対するエンドプレート２４の位置決めが自動的に行われる。 After the foreign matter is removed from the spline portion 151, the first rod portion 221 is pushed into the brake support member 21 until the rod-side step portion 223 of the rod 22 contacts the hole-side step portion 293 of the rod through hole 29. . At this time, the end plate 24 is brought close to the brake support member 21 while sliding each brake disk 251 to the spline portion 151. When the rod-side step 223 contacts the hole-side step 293, the end plate 24 returns to the original position, and the end plate 24 is automatically positioned with respect to the brake support member 21.
　この後、第２のロッド部２２２に取り付けられている固定ナット２３を締め込んで、ロッド２２をブレーキ支持部材２１に固定する。 Thereafter, the fixing nut 23 attached to the second rod portion 222 is tightened to fix the rod 22 to the brake support member 21.
　この後、ブレーキ支持部材２１及びアマチュア２６から保持具４１を外す。このようにして、スプライン部１５１に対する清掃作業を行う。 After this, the holder 41 is removed from the brake support member 21 and the armature 26. In this way, the cleaning operation for the spline portion 151 is performed.
　このようなブレーキ装置７では、アマチュア２６が制動位置にあるときに、スライド被押圧体２５が設定範囲Ａに収まるようになっており、第２のロッド部２２２におけるブレーキ支持部材２１から突出する部分の長さＬ１が、設定範囲Ａの寸法よりも長くなっているので、スプライン部１５１を清掃するときに、固定ナット２３を第２のロッド部２２２に取り付けたまま、各ブレーキディスク２５１の通常の可動範囲Ｂから外れた位置へ各ブレーキディスク２５１を移動させることができる。これにより、エンドプレート２４をロッド２２から外したりロッド２２をブレーキ支持部材２１から外したりせずに、スプライン部１５１の清掃を行うことができる。即ち、ブレーキ装置７を分解しないでスプライン部１５１の清掃を行うことができる。従って、ブレーキ装置７のメンテナンス作業の手間の軽減化を図ることができる。 In such a brake device 7, when the armature 26 is in the braking position, the slide pressed body 25 falls within the setting range A, and the portion protruding from the brake support member 21 in the second rod portion 222. Since the length L1 of the brake disc 251 is longer than the dimension of the setting range A, when the spline portion 151 is cleaned, the fixing nut 23 remains attached to the second rod portion 222. Each brake disk 251 can be moved to a position outside the movable range B. Thereby, the spline part 151 can be cleaned without removing the end plate 24 from the rod 22 or removing the rod 22 from the brake support member 21. That is, the spline part 151 can be cleaned without disassembling the brake device 7. Therefore, it is possible to reduce the maintenance work of the brake device 7.
　また、ブレーキディスク２５１には、スプライン部１５１に接触する清掃部材３３が設けられ、清掃部材３３は、砥石、やすり又はブラシであるので、ブレーキディスク２５１を移動させるだけで、スプライン部１５１に付着している異物を容易にかつより確実に除去することができる。 Further, the brake disk 251 is provided with a cleaning member 33 that contacts the spline part 151. Since the cleaning member 33 is a grindstone, a file, or a brush, the brake disk 251 adheres to the spline part 151 only by moving the brake disk 251. It is possible to easily and more reliably remove the foreign matter.
　また、ブレーキディスク２５１には、スプライン部１５１に接触する清掃部材３３が押圧ばね３５を介して設けられているので、スプライン部１５１に清掃部材３３を押圧ばね３５によって押圧することができ、スプライン部１５１に付着した異物をさらに確実に除去することができる。また、ブレーキ装置７の通常使用時には、ブレーキディスク２５１がスプライン部１５１に対してスライドされても、押圧ばね３５の弾性変形によって清掃部材３３をスプライン部１５１に対して移動させないようにすることができる。これにより、ブレーキ装置７の通常使用時に清掃部材３３が擦れることによって生じるスプライン部１５１の不必要な摩耗を防止することができる。 Moreover, since the cleaning member 33 which contacts the spline part 151 is provided in the brake disk 251 via the press spring 35, the cleaning member 33 can be pressed to the spline part 151 by the press spring 35, and the spline part Foreign matter adhering to 151 can be further reliably removed. In addition, during normal use of the brake device 7, even if the brake disk 251 is slid with respect to the spline portion 151, the cleaning member 33 can be prevented from moving with respect to the spline portion 151 due to elastic deformation of the pressing spring 35. . Thereby, unnecessary wear of the spline portion 151 caused by rubbing the cleaning member 33 during normal use of the brake device 7 can be prevented.
　また、スライド被押圧体２５は、２つのブレーキディスク２５１と、２つのブレーキディスク２５１の間に配置され、第１のロッド部２２１にスライド可能に設けられている中間プレート２５２とを有しているので、２つのブレーキディスク２５１を有するブレーキ装置７に対してメンテナンス作業の手間の軽減化を図ることができる。 The slide pressed body 25 includes two brake discs 251 and an intermediate plate 252 that is disposed between the two brake discs 251 and is slidably provided on the first rod portion 221. Therefore, the maintenance work for the brake device 7 having the two brake disks 251 can be reduced.
　なお、上記の例では、スライド被押圧体２５が有するブレーキディスク２５１の数が２つになっているが、３つ以上のブレーキディスク２５１をスライド被押圧体２５が有していてもよい。この場合、各ブレーキディスク２５１のそれぞれの間に中間スライド部材である中間プレート２５２が配置される。 In the above example, the number of brake disks 251 included in the slide pressed body 25 is two, but the slide pressed body 25 may include three or more brake disks 251. In this case, an intermediate plate 252 that is an intermediate slide member is disposed between each brake disk 251.
　また、上記の例では、ブレーキライニング３２がアマチュア２６、中間プレート２５２及びエンドプレート２４のそれぞれに設けられているが、各ブレーキディスク２５１のそれぞれにブレーキライニング３２を設けてもよい。このようにしても、アマチュア２６とブレーキディスク２５１との間、ブレーキディスク２５１と中間プレート２５２との間、及びブレーキディスク２５１とエンドプレート２４との間のそれぞれにブレーキライニング３２が介在した状態で、スライド被押圧体２５をエンドプレート２４に押圧することができ、各ブレーキディスク２５１に制動力を与えることができる。 In the above example, the brake lining 32 is provided on each of the amateur 26, the intermediate plate 252 and the end plate 24. However, the brake lining 32 may be provided on each brake disk 251. Even in this case, with the brake lining 32 interposed between the amateur 26 and the brake disk 251, between the brake disk 251 and the intermediate plate 252, and between the brake disk 251 and the end plate 24, The slide pressed body 25 can be pressed against the end plate 24, and a braking force can be applied to each brake disk 251.
　また、上記の例では、２つのブレーキディスク２５１のうち、一方のブレーキディスク２５１にのみ清掃部材３３が設けられているが、２つのブレーキディスク２５１のそれぞれに清掃部材３３を設けてもよい。 In the above example, the cleaning member 33 is provided only on one of the two brake disks 251, but the cleaning member 33 may be provided on each of the two brake disks 251.
　実施の形態２．
　図７は、この発明の実施の形態２によるブレーキ装置７を示す縦断面図である。また、図８は、図７の回転軸１５に対する制動力を解除しているときのブレーキ装置７を示す縦断面図である。なお、図７は、回転軸１５に対する制動力を発生しているときのブレーキ装置７を示している。スライド被押圧体２５は、１つのブレーキディスク２５１を有している。ブレーキディスク２５１には、スプライン部１５１に接触する清掃部材３３が設けられている。清掃部材３３は、弾性体である押圧ばね３５を介してブレーキディスク２５１に取り付けられている。ブレーキディスク２５１、清掃部材３３及び押圧ばね３５の構成は実施の形態１と同様である。 Embodiment 2. FIG.
FIG. 7 is a longitudinal sectional view showing a brake device 7 according to Embodiment 2 of the present invention. FIG. 8 is a longitudinal sectional view showing the brake device 7 when the braking force to the rotating shaft 15 in FIG. 7 is released. FIG. 7 shows the brake device 7 when the braking force for the rotating shaft 15 is generated. The slide pressed body 25 has one brake disk 251. The brake disk 251 is provided with a cleaning member 33 that contacts the spline portion 151. The cleaning member 33 is attached to the brake disc 251 via a pressing spring 35 that is an elastic body. The configurations of the brake disk 251, the cleaning member 33, and the pressing spring 35 are the same as those in the first embodiment.
　アマチュア２６が制動位置にあるときには、アマチュア２６とブレーキディスク２５１との間、及びブレーキディスク２５１とエンドプレート２４との間のそれぞれにブレーキライニング３２が介在した状態で、スライド被押圧体２５がエンドプレート２４に押圧される。スライド被押圧体２５がエンドプレート２４に押圧されている状態では、ブレーキライニング３２がブレーキディスク２５１に接触する。即ち、スライド被押圧体２５がエンドプレート２４に押圧されると、ブレーキディスク２５１がブレーキライニング３２で両側から挟圧される。これにより、ブレーキディスク２５１及び回転軸１５に制動力が与えられる。 When the amateur 26 is in the braking position, the slide pressed body 25 is moved between the armature 26 and the brake disk 251 and between the brake disk 251 and the end plate 24 with the brake lining 32 interposed therebetween. 24 is pressed. In a state where the slide pressed body 25 is pressed against the end plate 24, the brake lining 32 contacts the brake disc 251. That is, when the slide pressed body 25 is pressed against the end plate 24, the brake disk 251 is clamped from both sides by the brake lining 32. As a result, a braking force is applied to the brake disk 251 and the rotating shaft 15.
　アマチュア２６が解除位置にあるときには、スライド被押圧体２５がエンドプレート２４に押圧された状態が解除される。これにより、各ブレーキライニング３２がブレーキディスク２５１から離れ、ブレーキディスク２５１及び回転軸１５に対する制動力が解除される。他の構成は実施の形態１と同様である。 When the amateur 26 is in the release position, the state in which the slide pressed body 25 is pressed by the end plate 24 is released. Thereby, each brake lining 32 leaves | separates from the brake disc 251, and the braking force with respect to the brake disc 251 and the rotating shaft 15 is cancelled | released. Other configurations are the same as those in the first embodiment.
　このように、スライド被押圧体２５が有するブレーキディスク２５１の数が１つである場合でも、エンドプレート２４をロッド２２から外したりロッド２２をブレーキ支持部材２１から外したりせずにブレーキ装置７を分解しないで、スプライン部１５１の清掃を行うことができる。従って、ブレーキ装置７のメンテナンス作業の手間の軽減化を図ることができる。 As described above, even when the number of brake discs 251 included in the slide pressed body 25 is one, the brake device 7 is removed without removing the end plate 24 from the rod 22 or the rod 22 from the brake support member 21. The spline portion 151 can be cleaned without disassembling. Therefore, it is possible to reduce the maintenance work of the brake device 7.
　なお、上記の例では、ブレーキライニング３２がアマチュア２６及びエンドプレート２４のそれぞれに設けられているが、図９に示すように、ブレーキディスク２５１の両面にブレーキライニング３２を設けてもよい。このようにしても、アマチュア２６とブレーキディスク２５１との間、及びブレーキディスク２５１とエンドプレート２４との間のそれぞれにブレーキライニング３２が介在した状態で、スライド被押圧体２５をエンドプレート２４に押圧することができ、ブレーキディスク２５１に制動力を与えることができる。 In the above example, the brake lining 32 is provided on each of the amateur 26 and the end plate 24, but the brake lining 32 may be provided on both surfaces of the brake disc 251 as shown in FIG. Even in this case, the slide pressed body 25 is pressed against the end plate 24 with the brake lining 32 interposed between the armature 26 and the brake disk 251 and between the brake disk 251 and the end plate 24. The braking force can be applied to the brake disc 251.
　また、各上記実施の形態では、スプライン部１５１に接触する清掃部材３３が押圧ばね３５を介してブレーキディスク２５１に取り付けられているが、ブレーキディスク２５１に清掃部材３３を直接取り付けてもよい。このようにしても、清掃部材３３をスプライン部１５１に接触させながら、ブレーキディスク２５１と一体に清掃部材３３を移動させることができ、スプライン部１５１に付着した異物を除去することができる。 In each of the above embodiments, the cleaning member 33 that contacts the spline portion 151 is attached to the brake disk 251 via the pressing spring 35. However, the cleaning member 33 may be directly attached to the brake disk 251. Even in this case, the cleaning member 33 can be moved integrally with the brake disk 251 while the cleaning member 33 is in contact with the spline portion 151, and foreign matter adhering to the spline portion 151 can be removed.
　また、各上記実施の形態では、清掃部材３３がブレーキディスク２５１に設けられているが、清掃部材３３はなくてもよい。このようにしても、ブレーキディスク２５１の通常の可動範囲Ｂから外れた位置へスライド被押圧体２５を移動させることができ、ブレーキディスク２５１の通常の可動範囲Ｂでスプライン部１５１の全体を露出させることができる。これにより、可動範囲Ｂでのスプライン部１５１を容易に清掃することができ、ブレーキ装置７のメンテナンス作業の手間の軽減化を図ることができる。 Further, in each of the above embodiments, the cleaning member 33 is provided on the brake disk 251, but the cleaning member 33 may not be provided.

Thereby, the spline part 151 in the movable range B can be easily cleaned, and the maintenance work of the brake device 7 can be reduced.
