Our country has been using the three-arc straight-line tooth profile of the former Soviet Union and Europe, although the transmission performance is good, but the design and manufacture are relatively complex. The involute tooth shape of 30 degree pressure angle is called HV chain drive, which ha...

Synchronized belt drive is a kind of meshing transmission between belt teeth and belt gear slots. Compared with gear meshing transmission, it also has the advantages of uniform instantaneous speed (i.e., good synchronization) and high transmission efficiency, but it has the advantages of larger s...

Noise plays an important role in evaluating the performance of machine tools. High torque arc synchronous belt drive is the main drive of modern NC machine tools. So how to control the noise of machine tools under the condition of high speed transmission? Reducing the noise of machine tools main...

1. Lifting accessories coupling oil shortage or lack. Or improper use of grease, resulting in calcification of grease, resulting in non-lubrication between the tooth surfaces of Plum Blossom Elastic Couplings, or poor lubrication, resulting in serious wear of the tooth surfaces. This situation ca...

In the structural design and series design of various coupling forms, the maximum and minimum range of shaft holes and the length of shaft holes are determined according to the magnitude of transmission torque, the structure of coupling and the contour strength.

The diaphragm coupling can compensate for the axial, radial and angular deviations between the active and slave motors caused by manufacturing errors, installation errors, load-bearing deformation and temperature rise changes.

Vibration analysis is one of the techniques to predict misalignment of coupling. It can judge the gradual change trend of equipment state. But when judging whether a device is in misalignment state, it is necessary to refer to a lot of data and examples in the past. It is also necessary to check ...
