Coupling spacing
Thread Content
Could someone please give some advice? What should be the appropriate distance between the coupling between the slurry pump and the motor? Is it related to the pump’s speed?
Coupling torque calculation: The power of the power source in the transmission system should be greater than the power required by the workpiece machine. The theoretical short torque T at the high-speed end connected to the power unit can be calculated based on the power and speed of the power unit ； Based on the operating condition coefficient K and other relevant coefficients, the calculated torque Tc of the coupling can be determined. The coupling T is inversely proportional to n; therefore, T at the low-speed end is greater than T at the high-speed end.
Thank you to the moderator for the method of calculating coupling torque. However, what I’m more eager to know is the issue of the spacing between couplings, that is, the distance between the two mating wheels
Normally, I see that maintenance technicians keep it within 2–3 MM; I’m not sure about the reason behind this. I think as long as both ends operate in balance, there shouldn’t be any major problems.
Our pins are also usually around 2-3 mm in length
This spacing should be determined based on your coupling! ! Look at what kind of coupling you’ve used! !
The spacing between couplings of different types varies. The selection of a coupling depends on the motor’s speed and power; generally, the dimensions of couplings are provided in the product catalogs issued by coupling manufacturers, so you can take a look at those
