Damage to the coupling, There are many problems, such as torque overload, uncoordinated product clearance, especiallyPin couplingThe question starts withHL4For example, the connector is woolen polyurethane with a pin diameter of 30 mm. If the torque is too high, the pin will be broken.When the pin and the pin hole are too tight, it will not be able to compensate for the concentricity of the equipment at both ends. If the working state of the product equipment should lose concentricity, it will cause jitter and affect the equipment.When the pin gap is too large, not only will the torque be reduced, but the pin will also be unused.How to pay attention? The assembly is strict, and the reasonable clearance of the product is the top priority!Come to the company if you have any difficulties!
