    • PROBLEM TO BE SOLVED: To prevent local abrasion of a contact portion between a roller rolling and guiding a timing chain and a roller shaft rotatably supporting the roller.SOLUTION: A plurality of roller shafts 31 are provided at intervals in the longitudinal direction of guide bases 21 oppositely disposed to one side of a torque transmitting timing chain 5, and rollers 41 each including a plurality of chain guiding needle roller bearings are rotatably supported respectively by the roller shafts 31. The roller 41 has a cylindrical shape having the same diameter over the entire axial direction, and is movable in the axial direction relative to the timing chain 5, and the roller 41 is supported movably in the axial direction of the roller shaft 31. By the relative movement of the roller 41 and the timing chain 5 in the axial direction, and by the movement of the roller 41 relative to the roller shaft 31 in the axial direction, the contact portion between the roller 41 and the roller shaft 31 is varied in the axial direction, so that radial load is not applied locally.
    • 要解决的问题:为了防止辊滚动和引导正时链条之间的接触部分和可旋转地支撑辊子的辊轴的局部磨损。 解决方案:多个辊轴31沿着与转矩传递正时链条5的一侧相对设置的引导基座21的纵向间隔设置,并且每个包括多个链条引导滚针轴承的滚子41 可旋转地支撑在辊轴31上。辊41具有在整个轴向上具有相同直径的圆柱形形状,并且可相对于正时链条5在轴向方向上移动,并且辊41以轴向方式可移动地支撑 通过辊41和正时链条5在轴向上的相对运动,以及辊41相对于辊轴31沿轴向方向的运动,辊之间的接触部分 41和辊轴31在轴向方向上变化,使得不局部施加径向载荷。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a pulley block in which a single-row bearing is used, looseness in the bearing is decreased, and the service life is ensured. SOLUTION: A ball 17 of a ball bearing 3 is constituted so that it comes in contact with an outer ring 15 and an inner ring 16 respectively at a point A1 and a point A2 in the direction A slanting in one direction from a bearing center C2. The ball comes also in contact with the outer ring 15 and the inner ring 16 respectively at a point B1 and a point B2 in the direction B slanting in the other direction from the bearing center C2. If the radius of curvature of an outer-ring raceway 15a on the side of the point A1 is taken as OR1, the radius of curvature of an outer-ring raceway 15b on the side of the point B1 is taken as OR2, the radius of curvature of an inner-ring raceway 16a on the side of the point A2 is taken as IR1, and the radius of curvature of an inner-ring raceway 16b on the side of the point B2 is taken as IR2, the following inequalities OR1 COPYRIGHT: (C)2005,JPO&NCIPI

    • PURPOSE:To obtain a pulley manufacturable by press machining and having light weight by providing a position fixing hole and a regulating part on the closed side of an inside fixing part to support an outside rotary part through a bearing. CONSTITUTION:A cup shape of a hollow shaft 9 with a bottom 9a and a cylinder 9b is pressed in and fixed to the inner ring's inside diameter portion 7 of a bearing 1, and a cup shape of an auxiliary shaft 12 with a bottom 2a and a cylinder 12b is pressed into the outside diameter portion 11 on the opening end side of the hollow shaft 9. In order to fix a pulley to a bracket 22 through a bolt 24, an eccentric hole 19 and a fitting hole 20 each coninciding the other at their axial directions are provided at the bottoms 9a and 12a. Also, at the bottom 9a, a hexagonal tension regulating part in the form of a hole 21 is provided on the opposite side to the eccentric hole 19, where the shaft is centered.
