| description | To provide a continuously variable transmission capable of suppressing wear of a sheave contact surface of a transmission belt.SOLUTION: A continuously variable transmission comprises a pair of pulleys each of which has a fixed sheave integrated with a rotating shaft and a movable sheave fitted to the rotating shaft so as to rotate integrally with the rotating shaft and to be movable in the axial direction of the rotating shaft, and a transmission belt wound around the pair of pulleys. A wall thickness of each of the fixed sheave and the movable sheave, in a range narrower than a radial width in a sheave contact surface of the transmission belt from a sheave outer diameter end toward a shaft center in a radial direction, is discontinuously thin in contrast with that in a range other than the narrower range.SELECTED DRAWING: Figure 3
【課題】伝動ベルトのシーブ接触面の摩耗を抑制することができる無段変速機を提供すること。【解決手段】回転軸と一体化された固定シーブと、回転軸と一体に回転するとともに回転軸の軸線方向に移動することができるように回転軸に嵌合した可動シーブとをそれぞれ有する一対のプーリと、一対のプーリに巻き掛けられた伝動ベルトとを備えた無段変速機であって、固定シーブ及び可動シーブのそれぞれの肉厚は、シーブ外径端から径方向で軸中心に向かって伝動ベルトのシーブ接触面における径方向の幅よりも狭い範囲が、狭い範囲以外に対して不連続で薄い。【選択図】図３ |
