The bearing contact angle and the roller half taper angle are two important parameters of a large taper conical roller bearing,they influence the load and life of the bearing.

Design of stamping mould of cold header for big cone angle conical roller;

Discussion on machining technology for spherical fiducial surface of tapered roller;

Study of generatrix shape of tapered roller processed with centerless grinding;

Improvement of regulation wheel guiding surface during tapered rollers outer surface grinding;

Contour surface construction of conical cam mechanism with swinging conical roller follower;

The design of the contour surface of the conical cam with translating conical roller follower;

In this paper,a special spherical surface cam with a conical roller follower is put forward.

Design of superfinish leading roll for producing taper roller;

Radius measuring instrument of taper rollers surface of ball;

Then, the number of cycles applying the contact stress on each part in period of working life is calculated, and the calculation formula of the contact stress, the fatigue strength and the static load strength for this taper roller bearing are derived.
