Analysis of Manufacturing Technology for the Spherical Head Supporting Part

摘要

The spherical head supporting part is an essential part which connects the shell of one kind of front drive axle body, wheel driving and steering, braking structure and other key parts of the body, and to assume the function of load-bearing, steering, driving, braking and so on, it also has an important implications on the load-bearing capacity, steering capability, reliability, service life and safety of the front drive axle. This article mainly introduce the manufacture of the spherical head supporting part which the both ends are thick while the middle part is thin, inside the part is empty, both the inner and outer part are spherical and has special structures. Mainly introduce the technology of dual spherical head forging, hard turning, trundle processing that are used in the manufacture of this spherical head supporting part. Overcome the challenge of dual spherical head forging technology, both ends with reverse fillet shaft induction hardening surface manufacture technology. Smoothly finished debugging and manufacturing the spherical head supporting part. Also finished the test of the front drive axle. The spherical head supporting part's function, strength, stiffness, reliability, fully meet the requirements of bench test, reliable, and fully meet the demand of the vehicle matching.
