Tips: Safe use of coupling

1. The coupling is not allowed to exceed the specified axis line skew and radial displacement, so as not to affect its transmission performance.
2. The bolts of the coupling shall not be loose or damaged; the keys of the coupling shall be closely matched and shall not be loose.
3. The gear coupling and the Oldham coupling should be lubricated regularly, and grease should be added once every 2 to 3 months, so as to avoid severe wear of the gear teeth and cause serious consequences.
4. The contact length of the tooth width of the gear coupling shall not be less than 70%, and its axial movement shall not exceed 5mm.
5. The coupling is not allowed to have cracks. If there are cracks, it needs to be replaced (it can be hit with a small hammer, and judged according to the sound).
6. The tooth thickness of the gear coupling is worn. When the wear amount of the lifting mechanism exceeds 15% of the original tooth thickness, the running mechanism should be scrapped when it exceeds 25%, and it should be scrapped when there are broken teeth.
7. If the elastic ring of the pin coupling and the sealing ring of the gear coupling are damaged and aged, they should be replaced in time.
