1. First, according to the requirements of mechanical properties and, if no tooth gap, the level of torsional rigidity, vibration, impact absorption, etc., select the appropriate type of flexible coupling.
2. From the driven machinery (such as electrical) power [KW, HP], and coupling using the rotational speed [N] to seek to withstand the torque coupling [TA]
TA (Kg.m) = 973.5 × KW / N (rpm) = 716.2 × HP / N (rpm) or TA (N · m) = 9550 × KW / N (r / min) 3. By being positive coefficient in the table Richard load factor K 1, running time factor K.
3, start-stop frequency coefficient K 3, ambient temperature coefficient of K 4, to seek correction torque [TD].
TD = TA · K 1 · K 2 · K 3 · K 4
4. Use common coupling torque [TN] must be greater than is being torque [TD].
TN ≥ TD
5 • Flexible couplings can bear the maximum torque [TM] must be greater than its original side and passive side of the maximum torque generated by the two sides [TS].
TM ≥ TS
6. To determine whether the scope of application of pore size.
7. Apart from the above selection steps, for the vibrational frequencies and must review. The torque changes in the natural vibration frequency and axis the number of [N 1] to avoid resonance phenomena.
