gear manufacturing

The loosening of the valve clamping part adopts the gear ring transmission mode. The gear ring transmission ratio is constant,

By coupling the strength design of gear based on EHL central stress fitting formula and the gear lubrication design based

Based on D-H formula, Dowson D and Higginson GR proposed the minimum oil film thickness formula of EHL in line

The root crack will directly change the effective cross-sectional area and moment of inertia of the simplified cantilever model of

Gear pair is the core component of gear transmission system, and time-varying meshing stiffness is the main excitation source of

In view of the distortion caused by various factors, such as the release of processing stress, the different time and

Generally, the heat treatment distortion of the controlled workpiece is focused on “quenching distortion”. The reason is that the quenching

1. Statistics of distortion data The distortion of batch gear production has statistical characteristics. In the mass production of gears,

The low life of the bevel gear of automobile rear axle in China is always a big problem. There are

1. Test to limit the effect of steel hardenability on distortion 1) Sample The test adopts two sizes of disk-shaped

The metallurgical factors of steel, such as grain size, non-metallic inclusions, banded structure, hardenability, etc., have an impact on the

It is the basic principle and method to reduce the distortion of workpiece to make the structure and quality of

During quenching and cooling, the workpiece will generate volume expansion and large thermal stress and structural stress. If the volume
