On the base of simply introducing running transmission mechanism of shearer,according to the theory of rack and pinion engagement,mainly analyses impact cause resulted from toothing between shearer involute sprocket and conveyor pin-rail,using the specific parameters.

An exact dynamic simulation of the gear mesh has come ture based on the advantage of Pro/E and ADAMS,taking the standard involute right tooth columnar gear as an example.

Comparison is made between the three kinds of bearing arrangement modes in bearing life and gear mesh.

The machining errors of gear that relate to the nature of involute are studied with gear engagement theory and combining grinding-machining in this paper and they are summarized as transmissio.

Based on the theories of digital conjugate surface and gear meshing,a method for machining Digital Gear Tooth Surfaces(DGTS) was proposed.

By the aid of theory of conjugate surfacesand theory of gear meshing, the generation of two dimen-sional digital tooth surfaces presented by discrete pointswas investigated.

Applying the research method of the theory of gear meshing,the author introduces the interrelated conception of t he sphere of gear research to the earn members.
