Abstract
A method and apparatus for forming and mounting a sleeve and a thrust member in a bore in a motor/gear drive housing shaft to support the motor/gear drive shaft against radial and axial movement. Gates are formed in the motor/gear drive housing and communicate with separate first and second bores in the housing. A mold core is inserted into the housing and closes off one bore to allow the injection of molten plastic into a cavity formed between the tip end portion of the mold core and the first bore to form an annular sleeve. The annular sleeve has an inner diameter larger than the outer diameter of the end tip portion of the motor/gear drive shaft to be nominally spaced from the outer diameter of the drive shaft, but is supportingly engaged by the drive shaft under radial deformation of the drive shaft. Insertion of the drive shaft into the housing causes the tip end portion of the drive shaft to sealing close the second bore in the housing allowing the injection of molten plastic into the second bore to form a thrust member axially engaged with the end of the drive shaft to resist axial movement of the drive shaft during operation.
