Embodiment Construction
[0018] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] A method for processing a steering gear support bushing according to the present invention, comprising:
[0020] In the first step, concave grooves 1 a are evenly distributed along the inner hole of the rack housing 1 in the circumferential direction; the number of concave grooves 1 a is 4-9.
[0021] In the second step, the support pad 2 is injection-molded at the concave groove on the rack housing 1. The injection-molded support pad includes the convex part 2a injected into the concave groove of the rack housing 1, and the injection molding on the rack housing. The annular part 2b of the inner hole of the body 1; the annular part has through holes 2c uniformly distributed in the circumferential direction and serrated protrusions 2d; the convex part 2a and the annular part 2b of the injection-molded support pad are integrated with the rack hous...
