WH slider couplingIt is composed of two shafts and a central slider.The central sliding block acts as a torque transmitting element, which is usually made of engineering plastics.Other materials can be selected under special circumstances, such as metal materials.
Due to the reduced mass of the middle sliding block and elasticity, it has a higher limit speed.The middle sliding block can also be made of nylon, and the amount of graphite or molybdenum dioxide is added during the preparation so that it can be lubricated by itself during use. This kind of coupling has a simple structure and a compact size. It is suitable for low power and high speed. There is no severe impact.Couplings are noisy, low in efficiency, and wear fast. Generally, they should not be used as much as possible. They are only used in applications with very low speed, such as ball mills.
The central sliding block is connected with the shaft sleeves on both sides by 90° oppositely distributed clamping grooves on both sides, so as to achieve the purpose of transmitting torque.The center sliding block and the shaft sleeve are matched with a slight pressure, which enables the coupling to run with zero clearance during the operation of the equipment.Over time, the slider may lose its recoilless function due to wear, but the center slider is not expensive and easy to replace. After replacement, it can still play its original performance.
