CouplingIt is the intermediate connecting part of each motion mechanism, it has a direct impact on the normal operation of each motion machine, so pay attention to the following 8 points when using:
1. The bolts of the coupling must not be loose or damaged.
2. The coupling is not allowed to have cracks, if there is a crack, it needs to be replaced (it can be knocked with a small hammer, judged by the sound).
3. The key of the coupling should be tightly matched and not loose.
4. The coupling is not allowed to have a skew and radial displacement exceeding the specified axis line, so as not to affect its transmission performance.
5. If the elastic ring of the pin coupling and the sealing ring of the gear coupling are damaged and aging, please pay attention to timely replacement.
6. If the tooth thickness of the gear coupling is worn out, when the lifting mechanism exceeds 15% of the original tooth thickness, when it exceeds 25% of the original tooth thickness, it should be scrapped if there is a broken tooth.
7. The contact length of the tooth width of the gear coupling shall not be less than 70%, and the axial movement shall not be greater than 5mm.
8. Gear coupling and
Oldham couplingRegular lubrication is required, and grease is generally added once every 2 to 3 months to avoid severe consequences caused by severe wear of the gear teeth.
