How to use the coupling safely?

Normal useCouplingCan improve work efficiency, so what problems should we pay attention to when using it?yieldCoupling manufacturersTo explain to you:

1.CouplingMust not exceed the specified axis deflection and radial displacement, so as not to affect its transmission performance.

2. The bolts must not be loose or defective.

3. GearCoupling和Oldham couplingIt should be lubricated regularly, generally once every 2×3 months, to avoid serious gear wear and serious consequences.

4. GearCouplingThe contact length of the tooth width must not be less than 70%, and the momentum of the axial groove must not exceed 5 mm.

5.CouplingCracks are not allowed. If there is a crack, it needs to be replaced (it can be hit with a hammer and judged by sound).

6.CouplingThe keys should fit tightly and should not be loosened.

7. When the crane mechanism exceeds 15% of the original tooth thickness, the working mechanism exceeds 25%, and when there is a broken tooth, the tooth thickness of the gear coupling should be scrapped.

8. Column pinCouplingIf the elastic ring and the sealing ring of the gear coupling are damaged or aging, they should be replaced in time.

CouplingThe installation error should be strictly controlled, and it is usually required that the installation error does not exceed the allowable compensation 1≤2.

Note that after checking the alignment of the two shafts connected, the relative displacement should not be greater than the allowable compensation.Minimizing the relative displacement can extend the service life of the connecting machine or coupling.

In order to meet the lubrication requirements of gear couplings, the amount, quality and sealing condition of the lubricating oil should be checked regularly, and should be supplemented or replaced when necessary.

For high-speed rotating machineryCoupling, Generally need to carry out dynamic balance test and assembly according to the label.The weight difference between the connecting bolts is strictly limited and cannot be replaced at will.
