Today I would like to introduce the important points of using shaft coupling:
1. The shaft 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 must not be loose or damaged; the keys of the coupling should be tightly fitted and must not be loose.
3. The gear coupling and the Oldham coupling should be lubricated regularly, usually every 2 to 3 months to add grease once, 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 the axial movement shall not be greater than 5mm.
5. The coupling is not allowed to have cracks, if there are cracks, it needs to be replaced (it can be tapped with a small hammer and judged by the sound).
6. The tooth thickness of the gear coupling is worn. When the wear of the lifting mechanism exceeds 15% of the original tooth thickness, it should be scrapped when the wear of the operating mechanism exceeds 25%, and it should also 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 or aged, they should be replaced in time.
If you’re interested in hearing more about our coupling feel free to give us a call or an email, or you can read more on the coupling product page.
