For some couplings, Figure 1, the replacement of flexible elements requires moving the coupling hubs along the shaft or moving the pump (or motor) on its base. For others it may require neither.
Coupling type and alignment The type and alignment of the coupling can also cause vibration in vertical pump motors. On hollow shaft designs, the coupling consists simply of the bolts that secure the ...
For most machines connected by a flexible coupling, the distance between shaft ends is quite specific, for example 1/2 in. on close-coupled drives, 7 in. on pump applications, or possibly 100 in ...
The right coupling for mechanical power transmission A wide range of couplings for power transmission ranging from miniature couplings, all steel gear couplings, flexible spider couplings, shaft ...
Coupling is when the turbine reaches roughly 90 percent of the speed of the pump. There is no more torque multiplication, and it would be at this stage when a lockup clutch would kick in. Lockup ...
"The pump -- is the motor but there is a long shaft that goes into where the water is to bring it up, and sends it through the pipeline," Zanoni said. "It has a coupling that holds the shaft together.
