側の何れか一方に用いて効果的とした■プーリに関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pulley which can be effectively used on either the driving side or the driven side of a V-belt transmission mechanism.
一般にＶベルト伝達機構は、駆動側■プーリと従動側Ｖ
プーリの組合せにより動力を伝達するものであるが、Ｖ
ベルトとＶプーリの接触面は左右二面あり、その両接触
面は実際上傾斜等に微差があるためＶベルトが■プーリ
に接触するピッチ径が左右で異なる。In general, the V-belt transmission mechanism consists of a drive side pulley and a driven side V
Power is transmitted by a combination of pulleys, but V
There are two contact surfaces between the belt and the V pulley, left and right, and since there is actually a slight difference in slope between the two contact surfaces, the pitch diameter at which the V belt contacts the pulley differs between the left and right sides.
したがってＶベルトおよび■プーリの左右両面で接触す
るピッチ径が異なるためピッチ径周速度の誤差が発生し
て滑りを生ずる。Therefore, since the pitch diameters at which the V-belt and the left and right pulleys contact each other are different, an error in pitch diameter circumferential speed occurs, resulting in slippage.
したがって、摩擦ロスが発生し機械効率の低下、発熱の
増大はさけられない。Therefore, friction loss occurs, resulting in a decrease in mechanical efficiency and an increase in heat generation.
この発明はこのような点に鑑み、Ｖベルトと■プーリの

リを提供するものである。In view of these points, the present invention provides a (1) pulley that can automatically correct circumferential velocity errors on the friction surfaces of the V-belt and (1) pulley.

当接関連させたものである。FIGS. 1 and 2 show an embodiment of the pulley according to the present invention, in which a fixed conical plate 3 is fixed to the rotating shaft 1 with a key 2, and a fixed conical plate 3 is loosely fitted to the rotating shaft 1 via a sliding member 4. The floating conical plate 5 constitutes a pulley A, and the floating conical plate 5 of the V pulley
A friction body 7 integrally provided with a rotary shaft 1 and a key 6 is brought into contact with the outer surface of the rotary shaft 1.

れをＶプーリＡを介して従動軸１に伝達する。In the embodiment, the pulley A having the above configuration is provided on the driven side, and the V-belt 11 is passed between it and the pulley 10 on the driving side.
The rotation of the driving side pulley 10 is transmitted to the V belt 11, and this is transmitted to the driven shaft 1 via the V pulley A.
このとき、Ｖベルトの張力、回転力等によってその遊動
円錐板５を外方へ抑圧移動しこれを摩擦体７に適当な接
圧力のもとに当接せしめる。At this time, the floating conical plate 5 is pressed and moved outward by the tension, rotational force, etc. of the V-belt, and brought into contact with the friction body 7 under an appropriate contact pressure.

Since the circumferential speeds of the two friction surfaces 12, 12' and 13, 13' with respect to the rotating shaft are different, the floating conical plate 5 comes into contact with the friction body 7 fixed to the rotating shaft with a constant friction force, so that the friction surface 12.
The circumferential speed error at 13 is automatically corrected and becomes the same as the other friction surfaces 12' and 13', eliminating slippage between the V-belt and pulley 1, thereby eliminating friction loss.

An elastic needle roller 4 is attached to the boss portion 3a of the fixed conical plate 3.
The floating conical plate 5 is loosely fitted through the pulley, and the helical spring is fitted onto the boss portion 3a of the fixed conical plate on one end surface of the boss portion 5a of the floating conical plate 5 of the pulley. A friction body 7 made of the following is brought into contact with the friction body 7.
この実施例では摩擦体７に蔓巻発条を用いたが、先の実
施例と同様の周速度誤差修正動作を行うものである。In this embodiment, a helical spring is used for the friction body 7, but the same circumferential speed error correction operation as in the previous embodiment is performed.

て各種機械装置の高速化が実現できる。As explained above, this invention automatically corrects circumferential speed errors in the friction surfaces of the belt and pulley, which have traditionally been a bottleneck, and eliminates rotational resistance of the belt, thereby reducing the transmitted torque at high speed rotation. It can be maintained at approximately 100%, and as a result, it is possible to increase the speed of various mechanical devices by increasing mechanical efficiency and reducing heat generation.
