摘要： A tool for stamping annular blanks to form retainers for truncated spherical members in a single stroke stamping operation comprises a sectored punch having at least one pair of diametrically opposed sectors of a cyclinder separated from one another at their apexes such that the sectors of two punches can be intermated. The distal ends of the sectors are spherically contoured such that alternating spherical surfaces are formed on the inside surface of the retainers by two intermating sectored punches. The sectored punches form alternating cylindrical and spherical surfaces into the upper and lower portions of a blank to form the retainer. The cylindrical surfaces permit spherical members to be inserted into the retainers by hand or with the use of hand tools.

摘要： The present invention provides a retainer comprising a substantially planar support member having an opening therein designed to receive an annular member such as a bearing. Around the opening a plurality of slits are formed extending generally radially outwardly from the opening to form a plurality of retainer lips. The retainer lips are bent out of the plane of the support member such that the retainer will receive and fixedly engage the bearing in a snap fit. Bearing guides and steps may be used in aligning the bearing in the retainer.
摘要翻译：本发明提供了一种保持器，其包括基本上平面的支撑构件，其具有设置成容纳诸如轴承的环形构件的开口。围绕开口形成多个狭缝，其形成为从开口大致径向向外延伸以形成多个保持唇。保持器唇部从支撑构件的平面弯曲，使得保持器将以卡扣配合接收并固定地接合轴承。可以使用轴承导轨和台阶来对准保持架中的轴承。
