Drum gear coupling is widely used in industry. It is seldom used in people's life. Maybe you don't know much about it. As long as the machine is used for a long time, it is normal for the machine to fail, and the drum gear coupling is no exception. What are the common failures of the drum gear coupling?

If the design of drum gear coupling material is not reasonable enough, the top part of drum gear coupling will not reach the required accuracy. If the installation of the drum gear coupling is too large, it may cause the top clearance of the drum gear coupling to disappear. Another common fault is that the oil quality of the drum gear coupling is too poor, which will affect the working efficiency of the drum gear coupling when it operates.

Gear coupling is composed of inner ring with the same number of teeth and flange half coupling with outer teeth. The outer teeth are divided into straight teeth and drum teeth. The so-called drum teeth are spherical. The center of the spherical surface is on the axis of the gear. The backlash of the tooth is larger than that of the general gear. The drum teeth coupling can allow larger angular displacement (relative to the straight teeth coupling). It can improve the contact conditions of the teeth and improve the ability of transmitting torque. Long service life.

When the gear coupling is working, the relative displacement of the two axes occurs, and the tooth surfaces of the inner and outer teeth periodically slide in the opposite direction, which inevitably leads to tooth surface wear and power loss. Therefore, the gear coupling needs to work under good lubrication and sealing conditions. The gear coupling has small radial dimension, large load-carrying capacity, and is long for shafting transmission under low speed and heavy load conditions. The gear coupling with high accuracy and dynamic balance can be used for high-speed transmission, such as shafting transmission of dyeing steam turbine. Because the angular compensation of drum gear coupling is larger than that of straight gear coupling, drum gear coupling is widely used both at home and abroad. Straight tooth coupling belongs to the obsolete product, so the selector should not choose it as far as possible.
