The material of the slide coupling parts can be steel, and the working surface needs to be heat treated to improve its hardness, and stainless steel can also be used when the requirements are low, and no heat treatment can be carried out. In order to reduce friction and wear, oil should be injected into the oil hole of the intermediate disc for lubrication. The slider of the slider coupling is circular and made of steel or wear-resistant alloy, which is suitable for transmission with low speed and large transmission torque.
Slider couplings
The slide coupling is composed of two half-couplings with grooves on the end face and an intermediate disc with teeth on both sides, because the teeth can slide in the grooves, so the relative displacement between the two shafts can be compensated during installation and operation. The slider coupling should not be used in some important occasions, and the claw teeth of the casting are prone to tooth punching in the case of high load
Bending the spiral groove in two different directions at the same time creates a lot of internal pressure, which can lead to premature damage to the coupling, although the long spiral groove coupling can be easily bent under the condition of various deviations. A plurality of holes perpendicular to the direction of the axis of rotation are arranged at its joint, and a cylindrical slider body of polyurethane material is movably arranged in the hole.
Reel couplings.
In the drive drive system, the slide coupling has the function of buffering, damping and increasing the driving force of the shafting. In practical applications, it is usually connected with an intermediate shaft to improve the compensation performance of the two-axis offset. The working capacity of the relative offset of the two rotating prefabricated components, the manufacturing and installation deviations between the connected prefabricated components, the temperature transition and the force deformation in operation, etc., all clearly stipulate the movability.
