Introduction:

Drum gear coupling is widely used in industry, in people's life is rarely used, may we do not know too much about drum gear coupling. As long as it is a machine, with a long time, the failure of the machine is a very normal situation, drum gear coupling is no exception, the drum gear coupling common failure what?

Common failures of drum gear coupling:

If the material design of the drum gear coupling is not reasonable, the top of the drum type coupling tooth position will not reach the required accuracy. If the drum coupling is installed too large, it is likely to cause the top gap of the drum coupling teeth to disappear. There is a common fault is that the quality of the oil of the drum gear coupling is too poor, and the operation of the drum gear coupling will affect the efficiency of the drum gear coupling.

Gear coupling is made up of the same number of teeth inner ring and flange half coupling with outer teeth and other parts. The outer teeth are divided into straight teeth and drum teeth two kinds of teeth, the so-called drum teeth is to make the outer teeth into a sphere, the spherical center on the axis of the gear, the clearance of the tooth side is larger than the general gear, drum tooth coupling can allow a larger angular displacement (relative to the straight tooth coupling), can improve the contact conditions of the teeth, improve the ability to transfer torque, prolong the service life.

To sum up:

When the drum gear coupling is working, the two axes produce relative displacement, and the tooth surface of the internal and external teeth periodically make axial relative sliding, which will inevitably form the wear and power loss of the tooth surface, so the gear coupling needs to work in a good lubrication and seal state. The radial size of the gear coupling is small, the carrying capacity is large, and the long is used for the shafting drive of low speed and heavy load working conditions. The high-precision and dynamic balanced gear coupling can be used for high-speed transmission, such as the shafting drive of the steam turbine. Because the angular compensation of the drum type coupling is greater than that of the straight type coupling, the drum type coupling is widely used at home and abroad, and the straight type coupling belongs to the eliminated products, the user should try not to choose.
