1) The maximum operating compensation refers to the two-axis phase offset formed by the combined factors such as manufacturing errors, installation errors, and changes in working load caused by vibration, impact, and temperature changes in the working state.
2) The surface of half coupling, flange coupling, flange half coupling, brake wheel, brake wheel half coupling is not allowed to have cracks, shrinkage holes, air bubbles, slag inclusion and other defects that affect strength. The surface of the brake wheel should be quenched with a hardness of 45~55HRC, and the depth of the hardened layer is greater than 3mm.
3) The shape of the elastic parts should be smooth and flat, the working surface should not have pitting, and there should be no defects such as impurities, bubbles, cracks, etc. inside.
4) The shaft hole tolerance of the semi-coupling is in accordance with the provisions of GB/T3852-1997, and the surface roughness Ra value of the shaft hole is not less than 1.6um.
5) The coupling must be trial-assembled before leaving the factory. The half-coupling and the elastic part should be installed in no less than two positions relative to each other, which should be easy to install and disassemble.
6) The coupling used under high-speed working conditions should undergo a balance test with the main shaft system.
7) The coupling should be cleaned before packaging, and the coupling surface should be coated with anti-rust agent, and the non-coupling surface should be coated with paint or other anti-rust treatment.
