Abstract
A method of making a universal joint outer member affording a cavity with axially extending grooves in the wall thereof for receiving torque transmitting balls, comprising fitting into a preformed outer member, of light weight material, one or more wear resistant elements which define the grooves, and subjecting the assembly to an extrusion operation to secure the groove-defining elements in position and form the outer member to size.
Claims4
A method of making a universal joint outer member affording a cavity with axially extending grooves in the wall thereof for receiving balls for torque transmission, comprising the steps of providing at least one element affording groove-defining surfaces, providing an outer member affording a cavity shaped to receive said at least one groove-defining element and of a relatively light weight material permanently deformable by extrusion, introducing said at least one groove-defining element into said outer member, introducing into said outer member a former for determining the final positions of the grooves and dimensions of the cavity, and subjecting this assembly to an extrusion process to form the outer member to the required size and to secure said at least one groove-defining element therein.
