Most couplings have been standardized or standardized. The general mechanical designer’s task is to select couplings. The basic steps for selection are:
1. Select the type of coupling;
2. Calculate the calculated torque of the coupling;
3. Determine the type of coupling;
4. Check the maximum torque;
5. Coordinate the diameter of the shaft hole; specify the corresponding installation accuracy of the components;
6. Carry out necessary carrying capacity check.
Choose the type of coupling: You should fully understand the size and nature of the working load, the speed, the working environment, etc., and choose the type of coupling in combination with the performance, application range and use occasions of the common coupling.
Calculate the calculated torque of the coupling
TCA=KAT
T is the nominal torque transmitted by the coupling.
KA is the working condition coefficient.
Determine the coupling model: According to TCA≤[T], the coupling model is determined by the coupling standard, and [T] is the allowable torque of the coupling.
Check the maximum speed: the speed n of the connected shaft should not exceed the maximum speed nmax allowed by the coupling, namely
n≤max
Carry out necessary checks: In addition to meeting the requirements of torque and speed, the coupling should also be checked for the bearing capacity of the parts in the coupling when necessary, such as the allowable temperature check of non-metallic components.
