第３〜６図は、軸方向移動不可能な軸へのスラスト力
が働く嵌合部品12の抜け止めとして、部品16のこう配キ
ー及び部品17の山形板を使用した例である。FIGS. 3 to 6 show an example in which a gradient key of the component 16 and a chevron plate of the component 17 are used to prevent the fitting component 12 from exerting a thrust force on a shaft that cannot move in the axial direction.
このような従来技術には次のような問題点がある。 Such a conventional technique has the following problems.
（１） 部品12が肉厚の薄い歯車の場合は、こう配キー
16の打込みにより、打込み側のピツチ径が部分的に膨ら
みに起因する歯形の狂い、歯当りの悪化により、歯車の
強度低下、異常騒音等の不具合を発生する惧れがある。(1) If the part 12 is a thin gear,
There is a concern that the driving of No. 16 may cause irregularities in the tooth profile due to partial bulging of the pitch diameter on the driving side and deterioration of the tooth contact, resulting in problems such as reduced gear strength and abnormal noise.
（２） 軸方向の任意の位置決めは不可能である。(2) Arbitrary positioning in the axial direction is impossible.
本考案は、上記の問題点を解決したスラスト保持リン
グ装置を提供することを目的とするものである。An object of the present invention is to provide a thrust retaining ring device that solves the above-mentioned problems.
スラスト力が働くはすば歯車を回転軸に設けたキー溝
に嵌合される平行キーを介して回転軸に取付け、前記は
すば歯車のスラスト力が働く側にスクリュー保持リング
を、前記回転軸のキー溝上の任意位置で圧入固定したこ
とを特徴とする。A helical gear on which a thrust force acts is attached to a rotating shaft via a parallel key fitted into a key groove provided on the rotating shaft, and a screw holding ring is attached to a side of the helical gear on which a thrust force acts, by rotating the screw. The shaft is press-fitted and fixed at an arbitrary position on the keyway.
（１） 回転軸に歯車を装着する場合、歯車の変形が伴
なわないので、歯車の噛合に悪影響が出ない。このため
異常音の発生がなく、耐久性も向上する。(1) When a gear is mounted on the rotating shaft, no deformation of the gear accompanies, so that there is no adverse effect on meshing of the gear. Therefore, no abnormal sound is generated, and the durability is improved.
（２） 軸方向の位置決めが容易なので、相手ギヤに多
少の軸方向誤差が生じても容易に調整ができる。(2) Since positioning in the axial direction is easy, adjustment can be easily performed even if a slight axial error occurs in the mating gear.
（３） 回転軸に段差がなく、しかも軸端に止めねじや
スナツプリング用みぞ加工が不要なので、安価な締結が
可能となる。(3) Since there is no step on the rotating shaft and no set screw or groove for snapping is required at the shaft end, inexpensive fastening is possible.
第１図及び第２図に於いて、１は回転軸、２ははすば
歯車、３は平行キー、4,4はスラスト保持リングで、ス
ラスト保持リング４と回転軸１とは圧入状態にある。In FIGS. 1 and 2, 1 is a rotating shaft, 2 is a helical gear, 3 is a parallel key, 4 and 4 are thrust retaining rings, and the thrust retaining ring 4 and the rotating shaft 1 are press-fitted. is there.
次に、作用を説明する。 Next, the operation will be described.
回転軸１の回転力は、平行キー３を会して歯車２に伝
達される。歯車ははすば歯車なので、回転方向や、ねじ
れ方向の組合せによって、左右のスラスト力が発生す
る。The torque of the rotating shaft 1 is transmitted to the gear 2 through the parallel key 3. Since the gear is a helical gear, left and right thrust forces are generated depending on the combination of the rotation direction and the twist direction.
このとき、歯車はこれに対応して軸方向に移動しよう
とするが、本考案のスラスト保持リング４により、この
動きを阻止する。本考案は前記はすば歯車以外に、平歯
車、プーリ等の動力伝達部品にも適用できる。片側にの
みスラスト力が作用する場合は、スラスト保持リングも
片側だけに設ければよい。At this time, the gears try to move in the axial direction correspondingly, but this movement is prevented by the thrust retaining ring 4 of the present invention. The present invention can be applied to power transmission parts such as spur gears and pulleys in addition to the helical gears. When the thrust force acts on only one side, the thrust retaining ring may be provided only on one side.

Since it can be fixed at any position on the key groove, it can be easily adjusted even if a slight axial error occurs in the mating gear, or the helical gear is held without deformation of the helical gear when holding it. Since there is no adverse effect on the meshing of the shaft, no abnormal noise is generated and the durability is improved. Also, it is not necessary to machine grooves on the circumference of the rotating shaft such as set screws and snap rings. Has the effect of
