摘要： 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.
摘要翻译：一种用于在电机/齿轮驱动器壳体轴的孔中形成和安装套筒和推力构件以支撑马达/齿轮驱动轴以防止径向和轴向运动的方法和装置。门形成在马达/齿轮驱动器壳体中，并与壳体中的单独的第一和第二孔连通。将模芯插入到壳体中并封闭一个孔，以允许将熔融塑料注入形成在模芯的末端部分和第一孔之间的空腔中以形成环形套筒。环形套筒的内径大于马达/齿轮传动轴的端部末端部分的外径，与驱动轴的外径标称间隔，但在径向变形时由驱动轴支承地接合传动轴。驱动轴插入壳体中使得驱动轴的末端部分密封壳体中的第二孔，从而将熔融塑料注入第二孔中以形成与驱动轴的端部轴向接合的推力构件以防止在操作期间驱动轴的轴向运动。
