Selection of couplings
Oct 30, 2018

Hydraulic pump transmission shaft can not withstand radial force and axial force, so the shaft end is not allowed to directly install pulleys, gears, sprockets, usually with a coupling drive shaft and pump drive shaft. As a result of manufacturing reasons, pump and coupling coaxial degree exceeded, assembly and there are deviations, then with the speed of the pump to increase the centrifugal force increase the coupling deformation, large deformation and increase the centrifugal force. The result is a vicious cycle, which results in vibration noise, which affects the service life of the pump. In addition, such as the coupling pin loose when the fastening, rubber ring wear not timely replacement and other factors affecting.
