WH slider coupling

WH slider couplingAlso known as the metal cross slider coupling, the slider is ring-shaped and made of steel or alloy. The cross slider coupling is suitable for transmission with low speed and large transmission torque.The sliding block coupling is composed of two bushings and a sliding block.As a torque-transmitting element, the slider is usually made of engineering plastics. In this case, other materials, such as metal materials, can be selected.

The WH slider coupling utilizes the intermediate slider to slide in the corresponding radial grooves on the end faces of the half couplings on both sides to realize the coupling of the two halves. WH sliding block coupling is suitable for occasions where the speed n is less than 250 r/min, where the shaft has greater rigidity and does not have severe impact, such as ball mills.

The material of the WH slider coupling can be 45 steel, and the working surface needs to be heat treated to increase its hardness; Q275 steel can also be used when the requirements are lower, without heat treatment.In order to reduce friction and wear, oil should be injected from the oil hole of the middle plate for lubrication during use.Because the half-coupling and the intermediate disc form a moving pair and cannot rotate relative to each other, the angular velocity of the driving shaft and the driven shaft should be equal.However, when working with relative displacement between the two shafts, the middle disk will generate a large centrifugal force, which will increase the dynamic load and wear.Therefore, when selecting, pay attention that its working speed should not be greater than the specified value.Allowable compensation: axial x=1~2mm, radial y≤0.2mm, angular α≤40 degrees.

WH Slider Coupling Slider is generally made of nylon material, which is connected with the sleeves on both sides with 90° relative distribution on both sides, so as to achieve the purpose of transmitting torque. WH Slider Coupling The slider and the shaft sleeve are matched with a slight pressure. This pressure enables the coupling to run with zero clearance during the operation of the equipment.As the use time increases, the slider may lose its recoilless function due to wear. Therefore, the WH type slider coupling should be checked or replaced frequently.

WH Slider Couplings are often used in common motors, and can also be used to connect servo motors on individual occasions. The relative displacement can be corrected by the sliding of the slider during use.Because the resistance to the relative displacement is the friction between the slider and the sleeve, the bearing load between them will not increase due to the increase in the relative displacement.
