There are three types of coupling shaft deviations. The first type: radial deviation, that is, the two shafts are parallel but the center line is no longer on the same straight line. The deviation generated at this time is called the radial deviation; the second type is the angular deviation. That is, the deviation caused by the center of the two shafts at an angle to each other; the third type is the axial deviation, that is, the deviation caused by the reciprocating micro movement of the two shafts.
Deviations not only occur in the assembly of the equipment, but vibration, thermal expansion, bearing wear and other factors in the working process can cause deviations. Therefore, it is recommended to adjust the axial deviation to less than 1/3 of the maximum value.
The maximum allowable deviation of various couplings means that when only one deviation exists, when two or more deviations exist at the same time, the allowable value should be less than 1/2 of the maximum deviation in each specification table.

When the WGT drum gear coupling is in operation, the two shafts produce relative angular displacement, and the tooth surfaces of the inner and outer teeth periodically slide relative to each other in the axial direction, which will inevitably cause tooth surface wear and power consumption. Therefore, the gear coupling needs Work in a good and sealed state.
WGT drum gear couplings have small radial dimensions and large carrying capacity. They are often used in shaft transmissions under low-speed and heavy-duty conditions. High-precision and dynamically balanced gear couplings can be used for high-speed transmissions, such as combustion engines. The shafting transmission of the steam turbine.Since the angular compensation of drum gear couplings is greater than that of straight gear couplings, drum gear couplings are widely used at home and abroad. Straight gear couplings are obsolete products, and those who choose should try not to use them. .
