【０００２】[0002]
従来より、自動車或いはコンバインやトラクタ等の農業用機械等における変速 装置は、歯車式又は流体式のものが一般に広く使用されているが、近年、変速時 の操作性の向上、燃費の向上等を目的としてベルト式無段変速装置の開発が進め られている。 Conventionally, gear shifting in vehicles or agricultural machines such as combine harvesters and tractors Gear type or fluid type is generally widely used, but in recent years, during gear shifting Development of a belt-type continuously variable transmission for the purpose of improving operability and improving fuel efficiency Has been.
【０００３】 しかし、このベルト式無段変速装置に使用されるベルトは極めて高いトルクの 伝動能力を必要とし、従来の一般的なゴム製のＶベルトでは高い側圧に耐えきれ ず、座屈変形を生じて使用することができない。[0003] However, the belt used in this belt type continuously variable transmission has extremely high torque. Transmission power is required, and conventional general rubber V-belts can withstand high lateral pressure. Therefore, it cannot be used due to buckling deformation.
【０００４】 そこで、従来、斯かる要求を満足させるべく、各種の高負荷伝動用ベルトが知 られている（例えば特開昭４６−４８６１号、特開昭５５−２７５９５号、特開 昭５６−７６７４５号、特開昭５９−７７１４７号の各公報参照）。[0004] Therefore, in order to satisfy such requirements, various belts for high load transmission have been conventionally known. (For example, JP-A-46-4861, JP-A-55-27595, 56-76745 and JP-A-59-77147).
【０００５】 また、本出願人にあっては、基本的に、エンドレスの１対の張力帯と、左右側 面に該各張力帯を嵌合する嵌合溝及びプーリのベルト溝面に当接する当接部を有 する多数のブロックとで構成され、上記張力帯の上下面及び各ブロックの嵌合部 の上下面にそれぞれ互いに対応する嵌合可能な凹凸部を形成し、この張力帯及び 各ブロックの凹凸部を係合させて、ブロックを張力帯に対しベルト長手方向に係 止固定してなるブロックベルトと呼ばれる高負荷伝動用Ｖベルトを提案している （特開昭６０−４９１５１号公報、特開昭６１−２０６８４７号公報、特開昭６ ２−５４３４８号公報参照）。[0005] In addition, the applicant basically has a pair of endless tension bands and the left and right sides.

ところで、この種のブロックベルトにおいては、伝動可能な負荷に関連するプ ーリ推力を各ブロックで受ける構造であるので、該ブロックの強度を高めておか ないと、ブロック破壊に至る虞れがある。このため、各ブロックの内部に補強部 材を埋設することが行われているが、特に極めて高いトルクを連続的に作用させ た場合に対して、未だブロック強度が不足気味であり、改良の余地がある。 By the way, in this type of block belt, The structure is such that each block receives thrust, so the strength of the block must be increased. Otherwise, the block may be destroyed. For this reason, reinforcement parts are provided inside each block. Although the material is buried, it is necessary to apply extremely high torque continuously. However, the block strength is still insufficient, and there is room for improvement.
【０００７】 本考案は斯かる諸点に鑑みてなされたものであり、その目的は、上記のプーリ 推力により各ブロックの補強部材に加えられる応力を低減させる手段を講じるこ とにより、同荷重条件下における補強部材の応力値のピークを低減して、ブロッ クの破壊に至るまでの時間を大幅に延長し、ブロックベルトの高寿命化を図るこ とにある。[0007] The present invention has been made in view of the above points, and an object thereof is the above pulley. Take measures to reduce the stress applied to the reinforcing members of each block by thrust. By reducing the peak of the stress value of the reinforcing member under the same load condition, The time until the breakage of the block is significantly extended to extend the life of the block belt. And in.

この目的の達成のため、本考案の解決手段は、各ブロックにおいてその本体内 に埋設される補強部材を、ベルト幅方向に延びる上側及び下側ビーム部と、該両 ビーム部の中央部同士を上下に接続するセンターピラー部とで構成し、その補強 部材における上側ビーム部の根元部分に彎曲面を形成した。 To this end, the solution of the present invention is A reinforcing member embedded in the upper and lower beam portions extending in the belt width direction, Reinforced by the center pillar part that connects the central parts of the beam part up and down A curved surface was formed at the root of the upper beam portion of the member.
【０００９】 具体的には、本考案のＶベルトは、上下面に長手方向に並んで形成された上下 に対応する係合部を有し、内部に心線が埋設されたエンドレスの平ベルトからな る１対の張力帯を備えるとともに、本体内に、ベルト幅方向に延びる上側及び下 側ビーム部と、該両ビーム部の中央部同士を上下に接続するセンターピラー部と からなる補強部材を埋設してなる多数のブロックを備え、この各ブロックは、そ の外側面に上記張力帯を着脱可能に嵌合する切欠き状の嵌合溝と、該嵌合溝の上 下面にそれぞれ形成され、上記張力帯上下面の係合部にそれぞれ係合する係止部 と、外側面にプーリのベルト溝面に当接する当接部とを有し、張力帯の係合部と 各ブロックの係止部との係合により、ブロックが張力帯に対しベルト長手方向に 係止固定されてなるＶベルトである。[0009] Specifically, the V-belt of the present invention is a vertical belt formed on the upper and lower surfaces side by side in the longitudinal direction. The endless flat belt has an engaging part corresponding to And a pair of tension bands that extend in the belt width direction inside the body. A side beam portion and a center pillar portion that vertically connects the central portions of the both beam portions to each other It is equipped with a number of blocks in which a reinforcing member consisting of A notch-shaped fitting groove for detachably fitting the tension band on the outer surface of the Locking parts that are respectively formed on the lower surface and that engage with the engaging parts on the upper and lower surfaces of the tension band, respectively. And an abutting portion that abuts the belt groove surface of the pulley on the outer surface, By engaging with the locking part of each block, the block moves in the belt longitudinal direction with respect to the tension band. The V-belt is locked and fixed.
【００１０】 そして、その特徴は、上記各ブロックにおける補強部材は、その上側ビーム部 が中央部から両端部に向かって下方に彎曲していて、嵌合溝の上部ないし奥部に 対応する部分、つまり上側ビーム部の根元部分が彎曲面に形成されていることに ある。[0010] And the characteristic is that the reinforcing member in each block is Bends downward from the center toward both ends, and The corresponding part, that is, the base part of the upper beam part is formed in a curved surface is there.
【００１１】 また、請求項２の考案では、各ブロックにおける補強部材の上側ビーム部中央 に開口が形成されていることを特徴とする。[0011] Further, in the invention of claim 2, in the center of the upper beam portion of the reinforcing member in each block It is characterized in that an opening is formed in.
【００１２】[0012]
この構成により、請求項１の考案では、Ｖベルトがプーリのベルト溝面に係合 して負荷を伝動している状態では、各ブロックは、張力帯によりブロック上面か ら下面に向かう方向（プーリ中心に向かう方向）に押付力を、またベルト長さ方 向に剪断力をそれぞれ受け、上記剪断力によりブロック及びその内部の補強部材 が曲げられる。その際、ベルト回行方向の前側ではブロック及び補強部材表面は 引張応力面となり、後側面は圧縮応力面となる。このとき、補強部材において、 嵌合溝の上部ないし奥部に対応する、上側ビーム部の根元部分が彎曲面とされて いるので、この彎曲面により、該上側ビーム部根元部分への応力集中が緩和され る。その結果、補強部材ひいてはブロックの強度が高まり、よって極めて高いト ルクを連続的に作用させた場合であっても、ブロック破壊を回避でき、ベルトの 低速耐久性を高めることができる。 With this configuration, in the device of claim 1, the V-belt is engaged with the belt groove surface of the pulley. While the load is being transmitted by From the bottom to the bottom (direction toward the center of the pulley) Each block receives a shearing force in the same direction, and the shearing force causes the block and the reinforcing member inside the block. Can be bent. At that time, on the front side in the belt traveling direction, the block and the reinforcing member surface are It becomes a tensile stress surface and the rear side surface becomes a compressive stress surface. At this time, in the reinforcing member, The root of the upper beam, which corresponds to the top or back of the fitting groove, is a curved surface. Since this curved surface relieves stress concentration at the root of the upper beam, It As a result, the strength of the reinforcing member and thus of the block is increased, and therefore the extremely high strength Even if Luke is operated continuously, block destruction can be avoided and the belt Low speed durability can be improved.
【００１３】 請求項２の考案では、補強部材の上側ビーム部中央に開口が形成されているの で、該上側ビーム部が彎曲しているにも拘らず、補強部材の重心が上昇するのを 防いで、重心を張力帯の心線位置に位置付けることができるとともに、上側ビー ム部の重量増大を抑えることができ、よってベルトの高速耐久性を向上させるこ とができる。[0013] In the invention of claim 2, an opening is formed in the center of the upper beam portion of the reinforcing member. Therefore, it is possible to prevent the center of gravity of the reinforcing member from rising even though the upper beam portion is curved. The center of gravity can be positioned at the center line of the tension band by The increase in the weight of the belt can be suppressed, and thus the high speed durability of the belt can be improved. You can

【００１７】 上記各ブロック４は、図４に示すように、ブロック本体１４と、該ブロック本 体１４内にその略中央に位置するように埋設された補強部材９とからなる。そし て、上記補強部材９は、図５にも示すように、ベルト幅方向（左右方向）に延び る上側及び下側ビーム部１０，１１と、該両ビーム部１０，１１の左右中央部同 士を上下に接続するセンターピラー部１２とからなっていて、略Ｈ字状に形成さ れている。[0017] As shown in FIG. 4, each of the blocks 4 includes a block main body 14 and the block main body. The reinforcing member 9 is embedded in the body 14 so as to be located substantially at the center thereof. That The reinforcing member 9 extends in the belt width direction (left-right direction) as shown in FIG. Upper and lower beam parts 10 and 11 and the left and right central parts of the both beam parts 10 and 11 It is composed of a center pillar part 12 that connects the upper and lower players, and is formed in a substantially H shape. Has been.
【００１８】 さらに、本考案の特徴として、上記補強部材９における上側ビーム部１０は、 そのセンターピラー部１２に対応する中央部から左右両端に向かって下方に向か うように彎曲していて、全体として中高円弧状に曲がっている。また、この上側 ビーム部１０の彎曲により、上記各嵌合溝２上部ないし奥部に対応する、上側ビ ーム部１０の根元部分１０ａ（センターピラー部１２との接続部分）が略上側ビ ーム部１０に沿った彎曲面に形成されている。そして、上記上側ビーム部１０の 中央に開口としての貫通孔１３が貫通形成されている。[0018] Further, as a feature of the present invention, the upper beam portion 10 of the reinforcing member 9 is From the central portion corresponding to the center pillar portion 12 toward the left and right ends, It is curved like a curve, and is curved in a middle-high arc shape as a whole. Also above this Due to the bending of the beam part 10, the upper beam corresponding to the upper part or the inner part of each of the fitting grooves 2 is formed. The root portion 10a of the boom portion 10 (the connection portion with the center pillar portion 12) is substantially on the upper side. The curved surface is formed along the boom portion 10. Then, in the upper beam portion 10 A through hole 13 is formed as an opening in the center.
【００１９】 したがって、上記実施例においては、ＶベルトＡがプーリのベルト溝面に係合 して負荷を伝動している状態では、各ブロック４は、張力帯１，１によりブロッ ク４上面から下面に向かう方向（プーリ中心に向かう方向）に押付力を、またベ ルト長さ方向に剪断力をそれぞれ受けることになり、上記剪断力によりブロック ４及びその内部の補強部材９が曲げられる。その際、ベルト回行方向の前側では ブロック４及び補強部材９表面は引張応力面となり、後側面は圧縮応力面となる 。[0019] Therefore, in the above embodiment, the V belt A is engaged with the belt groove surface of the pulley. In the state where the load is transmitted to each block, each block 4 is blocked by the tension bands 1 and 1. 4 Apply pressing force in the direction from the upper surface to the lower surface (direction toward the pulley center), The shear force is applied in the length direction, and the shear force causes block 4 and the reinforcing member 9 inside thereof are bent. At that time, on the front side in the belt traveling direction The surface of the block 4 and the reinforcing member 9 becomes a tensile stress surface, and the rear surface becomes a compressive stress surface. .
【００２０】 そして、上記補強部材９の上側ビーム部１０の根元部分が彎曲面とされている ので、この彎曲面により、該上側ビーム部１０の根元部分１０ａへ上記応力が集 中せず、その根元部分１０ａに対する応力集中は確実に緩和される。このため、 補強部材９つまりブロック４の強度を高めることができ、よって、極めて高いト ルクが連続的に作用した場合であっても、ブロック４の破壊を防いで、ブロック ４の耐久性を高めてベルトＡの寿命を延ばすことができる。[0020] The base portion of the upper beam portion 10 of the reinforcing member 9 has a curved surface. Therefore, due to this curved surface, the stress is concentrated on the root portion 10a of the upper beam portion 10. The stress concentration on the root portion 10a is surely relieved without being centered. For this reason, It is possible to increase the strength of the reinforcing member 9, that is, the block 4, and thus the extremely high strength Prevents the destruction of Block 4 even if Luk acts continuously, 4 can be improved in durability and the life of the belt A can be extended.
【００２１】 また、このように上側ビーム部１０が中高状に彎曲することで、補強部材９の 重量が増大するとともに、その重心が張力帯１の心線１ａの位置（ピッチライン ）よりも上方にずれることが懸念される。しかし、この実施例では、上記上側ビ ーム部１０の中央に貫通孔１３が形成されているので、上記補強部材９の重心を 張力帯１の心線位置に位置付けることができ、しかも上側ビーム部１０の重量増 大をも抑えて、ベルトＡの高速耐久性を向上させることができる。[0021] In addition, by bending the upper beam portion 10 in a middle-height shape in this manner, the reinforcing member 9 As the weight increases, its center of gravity is located at the position of the core wire 1a of the tension band 1 (pitch line). ), There is a concern that it will shift upward. However, in this embodiment, the upper Since the through hole 13 is formed in the center of the arm portion 10, the center of gravity of the reinforcing member 9 is It can be located at the core position of the tension band 1, and the weight of the upper beam portion 10 is increased. It is possible to improve the high-speed durability of the belt A by suppressing the size.

Engaging a pair of tension bands formed with the engaging portions arranged side by side in the longitudinal direction There is a fitting groove, and the upper and lower surfaces of the fitting groove are engaged with the engaging portions of the upper and lower surfaces of the tension band. It is composed of a number of blocks with mating locking parts, and engages the engaging parts of the tension band and each block. By engaging with the locking part of the lock, the block is locked and fixed in the belt longitudinal direction with respect to the tension band. The upper beam part of the reinforcing member in each block is centered with respect to the fixed V belt. Bend downward from both sides toward both ends to correspond to the top or back of the fitting groove By configuring the base part of the upper beam part to be a curved surface, the upper part of the reinforcing member The stress acting on the root part of the beam is relaxed and the strength of the block under the same load condition is increased. Even if high torque is continuously applied, the block can be increased. It is possible to avoid breakage of the belt and, by extension, to significantly extend the life of the block belt. Wear.
【００２３】 請求項２の考案によると、各ブロックにおける補強部材の上側ビーム部中央に 開口を貫通形成したので、上側ビーム部の彎曲に伴う補強部材の重心の上昇移動 を防いで、重心を張力帯の心線位置に位置付けることができ、しかも上側ビーム 部の重量増大を抑えて、ベルトの高速耐久性の向上を図ることができる。[0023] According to the invention of claim 2, in the center of the upper beam portion of the reinforcing member in each block. Since the opening is formed through the opening, the center of gravity of the reinforcing member moves upward as the upper beam bends. The center of gravity can be positioned at the center of the tension band by preventing It is possible to improve the high-speed durability of the belt by suppressing an increase in the weight of the portion.
