摘要： A cold-formed ring gear is made from a relatively thin circular metal body, the outer peripheral edge of which is preformed to define a radially inwardly opening U-shaped channel in the outer surface of which the gear tooth pattern is subsequentially cold rolled using a known method and tooling. The unique preformed plate body obviates the need for a grooved interior supporting mandrel and results in a toothed rim of substantially enhanced strength and rigidity. The gear tooth pattern which is cold rolled in the preform provides tooth faces of substantially enhanced width and depth relative to the width and thickness of the base material from which they are formed. All of the other known advantages of cold formed teeth, as opposed to conventional cut teeth, are also realized.

摘要： A telescopic power transmitting unit. The power transmitting unit includes a tubular inner member having an outer longitudinal cylindrical section connected to a universal coupling and an inner splined section which is mounted for axial sliding movement within a central member having inner and outer splines extending the full length of the central member. An outer tubular member has an outer longitudinal cylindrical section connected to a universal coupling and an inner splined section which is mounted for sliding movement with respect to the outer spline of the central member. Circumferential guide rings are mounted on the inner and outer surfaces of the central member and aid in guiding the cylindrical sections of the inner and outer members relative to the central member and serve as stops to limit extension of the inner and outer members. A floating cylindrical shield is spaced radially outward of the outer member to prevent foreign material from contacting the splined sections.
摘要翻译：伸缩式动力传递装置。动力传递单元包括管状内部构件，其具有连接到通用联接器的外部纵向圆柱形部分和内部花键部分，该内部花键部分安装成在具有延伸中心构件的全长的内部和外部花键的中心构件内进行轴向滑动运动。外管状构件具有连接到通用联轴器的外纵向圆柱形部分和内花键部分，其被安装成相对于中心构件的外花键滑动。周向导向环安装在中心构件的内表面和外表面上，并且有助于相对于中心构件引导内部构件和外部构件的圆柱形部分，并用作限制内部构件和外部构件延伸的止挡件。浮动圆柱形护罩与外部构件径向向外间隔开，以防异物接触花键部分。
