摘要： A method of making a cage for use in a roller bearing comprises the steps of forming an inner circumferential groove centrally in an annular-shaped workpiece made of metal to define a circumferentially-extending side ring section on either side of the groove, punching the workpiece to form a plurality of axially-extending, circumferentially spaced-apart pockets for receiving rollers, and roughly abrading the outer peripheral surface of the workpiece. The punching and abrading steps inherently cause the outer peripheral surface of the workpiece at the side ring sections to become wavy, with a plurality of alternating recessed and raised portions. As a result of the abrading step, the difference in depth between the tops of the raised portions and the recessed portions is in the range of between approximately 60 .mu.m to 70 .mu.m. Accordingly, the outer peripheral surface of the workpiece is super finished to provide the tops of the raised portions with a cylindrical surface with a constant radius of curvature, while preserving the recessed portions. The workpiece is then split into two halves, following the super finishing step. As a result of the super finishing step, the difference in depth between the cylindrical surface and the recessed portions is in the range of between approximately 5 .mu.m to 50 .mu.m.
摘要翻译：一种制造用于滚子轴承的保持架的方法包括以下步骤：在由金属制成的环形工件中央形成内周槽，以在槽的任一侧上限定周向延伸的侧环部分，冲压工件以形成多个沿轴向延伸的周向间隔开的凹坑，用于接收辊子，并且大致磨蚀工件的外周表面。冲孔和研磨步骤固有地导致工件在侧环部分处的外周表面变成波状，具有多个交替的凸起和凸起部分。作为研磨步骤的结果，凸起部分的顶部和凹部之间的深度差在大约60μm至70μm之间的范围内。因此，对工件的外周面进行超精加工，以使凸起部的顶部具有恒定的曲率半径的圆筒面，同时保持凹部。然后在超精加工步骤之后将工件分成两半。作为超精加工步骤的结果，圆柱形表面和凹陷部分之间的深度差在大约5微米到50微米之间的范围内。

摘要： A protruding portion of a rotational speed detecting unit which is attached to a stationary side seal unit which is fixed to a stationary member which protruding portion protrudes axially and outer circumferentially of the stationary member is formed into a shape which has projecting portions in an axial direction, whereby the protrusion to the axial direction is reduced without reducing a bending strength in the axial direction, as a result of which the rotational speed detecting unit is miniaturized in the axial direction. Further, reinforcement members are embedded in an interior of the protruding portion, whereby the rotational speed detecting unit is miniaturized further in the axial direction.
