【産業上の利用分野】[Industrial applications]

この考案は、所定間隔離して配置された転がり軸受の外輪の相互間に介在され る転がり軸受用の間座に関する。 The present invention relates to a spacer for a rolling bearing, which is interposed between outer rings of rolling bearings which are spaced apart from each other by a predetermined distance.

【0002】[0002]

【従来の技術】[Prior Art]

従来、ハウジングの内部に軸方向へ所定間隔離した状態でアンギュラ軸受やテ ーパローラ軸受等の転がり軸受を配置したスピンドル等においては、両転がり軸 受間に間座を介在させて、転がり軸受の予圧調整(以下「隙間調整」も含む概念 として使用する)を行っている。 Conventionally, in spindles, etc. where rolling bearings such as angular bearings and taper roller bearings have been arranged inside the housing in the axial direction with a prescribed separation, a spacer is placed between both rolling bearings to preload the rolling bearings. Adjustments (hereinafter used as a concept that also includes “gap adjustment”) are being performed.

【0003】 ところで、スピンドルのハウジングに、予圧調整された転がり軸受を組付ける 場合、一般に、軸と転がり軸受との嵌合をタイトにし、軸受ナットやステップド スリーブを用いて、転がり軸受を軸方向に対して固定している。しかし、この組 付けに際して、軸受ナットの締めつけ加減、ステップドスリーブの押圧力、軸と 転がり軸受とのタイト量等の差異によって、所望の予圧を得られない場合がある 。By the way, when assembling a preload-adjusted rolling bearing in a spindle housing, generally, the fitting between the shaft and the rolling bearing is made tight, and the rolling bearing is axially moved by using a bearing nut or a stepped sleeve. Fixed against. However, in this installation, the desired preload may not be obtained due to differences in the amount of tightening of the bearing nut, the pressing force of the stepped sleeve, and the tight amount between the shaft and the rolling bearing.

【0004】 そこで、幅寸法を変化させることにより、転がり軸受の予圧を調整できるよう にした間座が提案されている(たとえば実公昭45−14964号公報参照)。 この間座は、一対の半円体を、端面同士を突き合わせた状態でピン結合し、この 結合体を2個組合わせて環状の間座としたものであり、各半円体の突き合わせ面 は、周方向へ沿って傾斜する互いに逆向きのテーパ面に形成されており、各半円 体を周方向に相対的に回動させることによって、その結合状態における総幅を調 整することができる。Therefore, a spacer has been proposed in which the preload of the rolling bearing can be adjusted by changing the width dimension (see, for example, Japanese Utility Model Publication No. 45-14964). This spacer is a pair of semicircular bodies that are pin-coupled with their end faces abutted, and two of these coupled bodies are combined to form an annular spacer. The abutting surface of each semicircular body is The tapered surfaces are formed so as to incline along the circumferential direction and are opposite to each other, and the total width in the coupled state can be adjusted by relatively rotating each semicircle in the circumferential direction.

【0005】[0005]

【考案が解決しようとする課題】[Problems to be solved by the device]

上記の構成の間座によれば、半円体同士を周方向に相対的に回動させることに より転がり軸受の予圧を調整することができるが、転がり軸受を軸に固定した状 態では、上記予圧調整を行うことができず、したがって予圧調整の都度、軸に対 する転がり軸受の固定を解除する必要があり、予圧調整に手間がかかるという問 題があった。 According to the spacer having the above structure, the preload of the rolling bearing can be adjusted by relatively rotating the semicircular bodies in the circumferential direction.However, in the state where the rolling bearing is fixed to the shaft, Since the above preload adjustment cannot be performed, it is necessary to release the fixation of the rolling bearing to the shaft each time the preload adjustment is performed, which causes a problem in that the preload adjustment takes time.

【0006】 また、上記テーパ面が、半円体の周方向へ沿って傾斜しているので、半円体の 組合わせ状態における端面の平行度をミクロン単位で確保する必要がある点と相 まって、当該テーパ面の加工が非常に困難であるという問題もあった。 この考案は上記問題点に鑑みてなされたものであり、転がり軸受を軸に固定し た状態で予圧調整を簡単に行うことができるとともに、製造の容易な転がり軸受 用の間座を提供することを目的とする。Further, since the tapered surface is inclined along the circumferential direction of the semicircular body, it is necessary to secure the parallelism of the end faces in the combined state of the semicircular bodies in the unit of micron. There is also a problem that it is very difficult to process the tapered surface. The present invention has been made in view of the above problems, and provides a spacer for a rolling bearing that allows easy preload adjustment while the rolling bearing is fixed to the shaft and is easy to manufacture. With the goal.

【課題を解決するための手段】[Means for Solving the Problems]

上記目的を達成するためのこの考案の転がり軸受用の間座としては、軸方向へ 所定間隔離した状態でハウジング内に配置された軸受外輪の相互間に介在される 転がり軸受用の間座であって、軸方向へ直列に配置された一対の環状体を備え、 各環状体の一端部が、周方向への回動操作によって軸方向へ互いに接離できるよ うに、ねじを介して互いに連結されているものである。 As a spacer for a rolling bearing of the present invention to achieve the above object, a spacer for a rolling bearing which is interposed between bearing outer rings arranged in a housing in a state of being separated by a predetermined distance in the axial direction is used. It has a pair of annular bodies arranged in series in the axial direction, and one end of each annular body is connected to each other via screws so that they can be brought into and out of each other in the axial direction by a rotational operation in the circumferential direction. It has been done.

【作用】[Action]

上記の構成の転がり軸受用の間座によれば、環状体を周方向へ相対回動させる ことによって、両者を軸方向へ接離させて、両環状体の総幅を調整することがで きる。したがって、転がり軸受を軸から取外すことなく予圧調整を行うことがで きる。 According to the rolling bearing spacer having the above-described configuration, the annular bodies are relatively rotated in the circumferential direction so that they are brought into contact with and separated from each other in the axial direction, and the total width of both annular bodies can be adjusted. . Therefore, the preload can be adjusted without removing the rolling bearing from the shaft.

【0010】 上記各転がり軸受2の内輪21間には、両者間の間隔を規制するスリーブ4が 介在されており、これら内輪21およびスリーブ4は、スピンドル軸3の一端部 に形成された鍔部31と、他端部に螺合された軸受ナット32との間で挟持され て、軸方向への移動が規制されている。また、右端の外輪22の端面は、ハウジ ング1の端部に形成された鍔部11に係止されており、これによって各転がり軸 受2の右方向への移動が規制されている。さらに、上記ハウジング1の他端部に は、転がり軸受2の外輪22と所定しめ代を設けた状態で、カバー12が取付け られている。なお、上記左側に配置された一対の転がり軸受2と、右側に配置さ れた一対の転がり軸受2とは、左右それぞれの外輪22をハウジング1の軸方向 外方へ押圧することにより予圧を調整できるように、互いに反対方向へ向けて配 置されている。また、同一方向へ向けて配置された一対の転がり軸受2間には、 両者の外輪22間の間隔を規制するためのスリーブ4aが介在されている。A sleeve 4 is interposed between the inner races 21 of the rolling bearings 2 to control the distance between the inner races 21. The inner race 21 and the sleeve 4 are formed on one end of the spindle shaft 3 with a collar portion. It is sandwiched between 31 and a bearing nut 32 screwed to the other end, and the movement in the axial direction is restricted. Further, the end surface of the outer ring 22 at the right end is locked to the flange portion 11 formed at the end portion of the housing 1, and thereby the rightward movement of each rolling bearing 2 is restricted. Further, a cover 12 is attached to the other end of the housing 1 with the outer ring 22 of the rolling bearing 2 and a predetermined interference. The pair of rolling bearings 2 arranged on the left side and the pair of rolling bearings 2 arranged on the right side adjust the preload by pressing the left and right outer rings 22 outward in the axial direction of the housing 1. As possible, they are arranged in opposite directions. Further, between the pair of rolling bearings 2 arranged in the same direction, a sleeve 4a for restricting the distance between the outer rings 22 is interposed.

【0011】 上記間座Aは、内側に配置された転がり軸受2のうちの一方の転がり軸受2の 外輪22に一端面を当接させた第1の環状体51と、他方の転がり軸受2の外輪 22に一端面を当接させた第2の環状体52とを備えている。そして、上記第1 の環状体51の他端部には雌ねじ51aが形成され、第2の環状体52の他端部 には雄ねじ52aが形成されており、各環状体51,52は、上記雌ねじ51a と雄ねじ52aとを互いに螺合させた状態で、同心にて軸方向へ直列に配置され ている。なお、第1の環状体51には、上記第2の環状体52の雄ねじ52aを 押圧して、両環状体51,52の相対的な回動を規制するための止めねじ53が 螺合されている。また、両環状体51,52の外周には、両者を相対的に回動操 作するための工具を係合するための係合孔51b,52bが、周方向へ沿って所 定間隔ごとに形成されている。The spacer A has a first annular body 51 having one end surface abutting on an outer ring 22 of one of the rolling bearings 2 arranged inside, and the other rolling bearing 2. The outer ring 22 is provided with a second annular body 52 whose one end surface is in contact with the outer ring 22. An internal thread 51a is formed on the other end of the first annular body 51, and an external thread 52a is formed on the other end of the second annular body 52. The female screw 51a and the male screw 52a are screwed together and are concentrically arranged in series in the axial direction. A set screw 53 for pressing the male screw 52a of the second annular body 52 to regulate the relative rotation of the two annular bodies 51, 52 is screwed into the first annular body 51. ing. Further, engaging holes 51b and 52b for engaging a tool for relatively rotating the two annular bodies 51 and 52 are provided on the outer periphery of the annular bodies 51 and 52 at regular intervals along the circumferential direction.

【0012】 以上の構成であれば、転がり軸受2をスピンドル軸3に固定した状態でハウジ ング1から取出し、一対の環状体51,52を周方向へ相対的に回動することに より、両環状体51,52の総幅Lを変化させて転がり軸受2の外輪22に対す る押圧力、すなわち予圧力を調整することができる。このように上記実施例によ れば、転がり軸受2をスピンドル軸3に固定した状態で、当該転がり軸受2の予 圧調整を行うことができるので、予圧調整を容易かつ迅速に行うことができる。 また、ねじを利用した予圧調整であるので、環状体を容易に製造することができ る。With the above configuration, the rolling bearing 2 is fixed to the spindle shaft 3 and is taken out from the housing 1, and the pair of annular bodies 51 and 52 are relatively rotated in the circumferential direction. The total width L of the annular bodies 51, 52 can be changed to adjust the pressing force, that is, the preload, against the outer ring 22 of the rolling bearing 2. As described above, according to the above-described embodiment, the preload adjustment of the rolling bearing 2 can be performed in a state where the rolling bearing 2 is fixed to the spindle shaft 3, so that the preload adjustment can be performed easily and quickly. . Further, since the preload adjustment is performed by using the screw, the annular body can be easily manufactured.

【0013】 なお、この考案の転がり軸受用の間座Aは、上記実施例に限定されるものでな く、たとえば図2に示すように、両環状体51,52の突き合わせ側の端部に、 互いに逆ねじの雄ねじ51c,52cを形成し、この雄ねじ51c,52cに対 して、途中から逆ねじを切った連結環54を螺合させてもよく、この場合には上 記連結環54と両環状体51,52とを相対的に回動させることによって、両環 状体51,52の総幅Lを調整することができる。The rolling bearing spacer A of the present invention is not limited to the above-described embodiment. For example, as shown in FIG. 2, the abutment side ends of both annular bodies 51 and 52 are provided. It is also possible to form male screws 51c and 52c of opposite threads to each other and screw a connecting ring 54 with a reverse thread cut from the middle to the male screws 51c and 52c. In this case, the above-mentioned connecting ring 54 By rotating the two annular bodies 51, 52 relative to each other, the total width L of the two annular bodies 51, 52 can be adjusted.

【0014】 また、上記間座Aは、高速回転時において軸受の円滑な回転を確保するための 軸受隙間の調整にも勿論用いることができる。The spacer A can also be used for adjusting the bearing clearance to ensure smooth rotation of the bearing during high-speed rotation.
