Multi-deformable-body dynamics analysis on the ring gear of planetary gear set

Elastodynamics of Spur Planetary Gear Transmissions in Consideration of Ring Gear Flexibility;

Manufacturing annular gear of coal with new matrial of 25Cr2MoVA,adopting reasonable thermal treatment technologies of secondary aging during rough and finish machining and final two-phase method gas nitriding to make tooth surface of annular gear obtain higher hardness and abrasive resistance to increase its service life.

This paper discusses that by using the tubular blank of the cold extrusion of annular gear,the exetent of deformation and the flow of the metal can be reduced;and the flow of deformation and the flexible deformation of the dies can alao be reduced.

The quality analysis for gas nitrocarburized inner gear ring of heavy truck imported from Austria was taken by means of macro/micro-examination, hardness measuring and running test.

In the condition of uniaxial drive,the bearing force of the three inner gear ring of 3-ring reducer is same.

The technology improvement of long inner gear circle;
