    • The present invention provides a manufacturing method of a spherical roller bearing retainer which comprises: a cage forming step of forming a material into a cup shape; a guide hole punching step of forming guide holes along the circumference of the cage divided equally and on which rollers are placed; a chamber forming step of forming a chamber on both sides of the guide hole to minimize the friction between the roller and the cage and to smoothly drive the roller; a bottom bore expanding step of expanding a hole on the bottom of the cage; and a cage-width processing step of removing burr generated on the upper and lower ends of the cage and to adjust the width measurement of the cage. The manufacturing method of a spherical roller bearing retainer is provided to reduce a contact area of a roller, thereby reducing the friction of the roller; and to smoothly supply lubricant to a gap between a guide hole and a roller to reduce the frictional heat of the roller, the frictional torque and vibration of a bearing, and the abrasion and noise of the bearing, thereby improving the properties of the bearing and extending the service life of the bearing.
    • 本发明提供了一种球面滚子轴承保持器的制造方法,该方法包括:将形成为杯状的材料的保持架形成步骤; 引导孔冲压步骤,沿着所述笼的圆周形成沿着所述平坦分割的导向孔,并且在所述辊上放置所述导向孔; 腔室形成步骤,在引导孔的两侧形成腔室,以最小化辊子和保持器之间的摩擦力并平滑地驱动辊子; 底部孔扩展步骤,其扩大所述笼的底部的孔; 以及保持架宽度加工步骤,去除在保持架的上端和下端产生的毛刺并调整保持架的宽度测量。 提供了一种球面滚子轴承保持器的制造方法,以减小辊的接触面积,从而减小辊的摩擦力; 并且平滑地将润滑剂供给到导向孔和滚子之间的间隙,以减小滚子的摩擦热,轴承的摩擦扭矩和振动以及轴承的磨损和噪音,从而改善轴承的性能和 延长轴承的使用寿命。
