WH type slider coupling
The structure of the WH type slider coupling is similar to the cross slider coupling, so it is also called a "slider coupling". The difference is that the middle cross slider is a square slider, and the middle slider is used for half coupling on both sides. The end face of the shaft slides in the corresponding radial groove to realize the coupling of the two halves of the shaft coupling.
WH-type slider coupling is suitable for occasions where the speed n is less than 250r/min, where the shaft has greater rigidity and no 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 low, 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 semi-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, pay attention to the working speed not greater than the specified value when selecting.Allowable compensation: axial x=1~2mm, radial y≤0.2mm, angular α≤40 degrees.
The center slider of the WH type slider coupling 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-type slider couplings are matched with a slight pressure between the center slider and the shaft sleeve. 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, so the WH type slider coupling should be checked or replaced frequently.
WH type slider coupling is often used in common motors, and can also be used to connect servo motors in individual occasions. The relative displacement is corrected by the sliding of the center slider during use.Because it is the friction between the slider and the sleeve that resists the relative displacement, the bearing load between them will not increase due to the increase in the relative displacement.
