Clamp on cutting bearing hole of coal car wheel;

It is very important to measure and control the position of bearing hole when machining canular forked shaft.

Fracture behavior of bearing hole on supporting bar was analyzed using scanning electron microscope(SEM) and energy dispersive spectroscopy(EDS).

Based on three-dimensional coupled thermo-mechanical finite element analysis,with the help of FEM software(ANSYS), temperature field and displacement field of thermal deformation of bearing borizing are given.

The system is based on the air-electric sensor technology,which can automatically measure cylinder hole and main bearing hole of the cylinder block,make grouping and marking and meet high precision measure requirements.

It′s always one of the difficulties to machine main bearing holes on bedplate for large bore diesel engines.

Taking the correction of the gear shaft and bearing saddle bore of a reducer as the example, this paper probes into the problem of the correction of the gear shaft and bearing saddle bore often encountered in the inspection of e lectromechanic equipment, and according to the practical experiences, makes emph atically discussion on the brush plating repair technique.
