Selection principle:

1) Torque T: T↑, select rigid coupling, non-elastic components or flexible coupling with metal elastic components; T has impact vibration, choose flexible coupling with elastic element;

2) Rotational speed n: n↑, flexible coupling of non-metallic elastic components;

3) For neutral: for neutral rigid coupling, flexible coupling should be selected when compensation is required;

4) Assembly and disassembly: considering the convenience of assembly and disassembly, choose the coupling with direct radial movement;

5) Environment: If working at high temperature, do not choose a coupling with non-metallic components;

6) Cost: under the same conditions, try to choose low price, simple maintenance.

Coupling type selection:

1) Simple selection type of coupling: TC=KT=9550KPw/n

Calculation torque type:

TC -- calculated torque, N·m;

T -- theoretical (nominal) torque, N·m;

K -- working condition coefficient, see Table 18-1;

Pw -- Theoretical (nominal) working power, kW;

n -- working speed, r/mm;

2) Τc≤[n] -- nominal torque and allowable torque of τc coupling, N·m; See an opportunity
