本発明はベルト式無段変速プーリ等の軸固定装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shaft fixing device for a belt type continuously variable speed pulley or the like.
ベルト式無段・変速プーリの固定円錐車等は、モーター
又は減速機の回転軸に取り付けるのが通常であり、この
場合、片持軸である。そのため固定円錐車を回転軸の根
本に取り付けていわゆるオーバーハング荷重を少くする
のが通例である。The fixed conical wheel of a belt-type continuously variable speed pulley is usually attached to the rotating shaft of a motor or speed reducer, and in this case, it is a cantilevered shaft. Therefore, it is customary to attach a fixed conical wheel to the base of the rotating shaft to reduce the so-called overhang load.

作ができないという欠陥が存した。From the above, conventionally, the rotary shaft and the boss of the fixed conical wheel are keyed together, a screw hole is provided in the boss in a direction perpendicular to the axial direction, and the tip of the fixing screw is screwed into this screw hole. is crimped onto the rotating shaft to fix the boss portion to the rotating shaft. However, the problem with screw fastening was that the fixing force between the boss and the rotating shaft was insufficient, and factors such as load fluctuations and shock loads caused problems such as wear of the key. As a means to solve the above defect, as shown in FIG. 4, a tapered member 4 is fitted to one end of the boss portion 2 in which a notch is formed in the axial direction, and the tapered member 4 has a tapered hole. The ring 6.8 is fitted and the ring 6.8 is fitted.
There is a fixing mechanism in which the boss part 2 is fixed to the shaft 12 by tightening the boss part 2a to the shaft 12 by tightening the boss part 2a in the axial direction. cannot be fixed. Furthermore, in the case of a motor shaft, there was a problem in that the motor 14 was in the way and the bolt could not be operated.
本発明は上記欠陥を除去することを目的とするものであ

に軸方向にスライド自在にキー結合している。A belt hooking surface 22d is formed on a monitoring portion 22c protruding from the boss portion 22a. Notches 24 and 26 are formed in one end of the boss portion 22a in the axial direction over a predetermined range. A keyway 28 is bored in the boss portion 22a in the axial direction. Reference numeral 30 designates a plurality of insertion holes 1 to 1 inserted concentrically through the monitoring portion 22c, and a recessed portion 30a for accommodating the head of a bolt is integrally formed in the insertion hole. Reference numeral 32 designates a tightening ring, which has a tapered surface corresponding to the tapered surface 22b formed on its inner diameter. The ring 32 has a plurality of threaded holes 34 formed therethrough in the thickness direction corresponding to the holes 30. 36
is a moving conical wheel, the boss portion of which is the aforementioned boss portion 22a.
The key is connected to the key so that it can slide freely in the axial direction.

リング３２を嵌合し、監部２２ｃの孔３０に挿入したボ
ルト４０を１１ング３２のねじ穴３４にゆるくねじ込む
。In the above configuration, when fixing the boss portion 22a to the shaft of a motor, for example, the ring 32 is fitted to one end of the boss portion 22a, and the bolt 40 inserted into the hole 30 of the guard portion 22c is inserted into the 11 ring. Loosely screw it into the screw hole 34 of 32.
次に、ボス部２２ａをモータ軸にその根本に達するまで
挿入し、モータ軸のキーをボス部２２ａのキー溝２８に
嵌合する。該状態において監部２２ｃはモータに近接対
向する。Next, the boss portion 22a is inserted into the motor shaft until it reaches its base, and the key of the motor shaft is fitted into the keyway 28 of the boss portion 22a. In this state, the monitoring section 22c faces the motor closely.

２ａはモータ軸に強固に固着される。Next, the bolt 40 is tightened tightly and rotated in the 3-direction to press the inner circumferential tapered surface of the ring 32 onto the tapered surface 22b of the boss portion 22a. Since notches 24 and 26 are formed at one end of the boss portion 22a, the pressure of the ring 32 causes the displacement in the diameter reduction direction, and the one end of the boss portion 22a is crimped to the outer circumferential surface of the motor shaft. Boss part 2 due to force
2a is firmly fixed to the motor shaft.
次に、ボス部２２ａに移動円錐車３６を取付ける。Next, the movable conical wheel 36 is attached to the boss portion 22a.

a along the axial direction, a bolt insertion hole 30 is opened at the other end of the boss portion 22a, the bolt is inserted through this opening, and the bolt is screwed into the screw hole of the tightening ring. Also good. In addition, in FIG. 1, 56 is a screw hole formed in the thickness direction of the guard part 22C. When tightening, when the ring 32 bites strongly into the tapered surface 22b, the bolt 40 is inserted into the screw hole 34.
If only the tapered surface 2 of the tightening ring 32 is loosened,
It is not possible to release the bite on 2b. Therefore, when you want to remove the boss portion 22a from the motor shaft,
The bolt 40 is removed from the screw hole 34, and then the bolt is screwed into the screw hole 56, and the tip of the bolt presses the tightening ring 32. As a result, the tightening ring 32 comes off the tapered surface 22b, and the boss portion 22a can be easily removed from the rotary motor shaft.
