Slider coupling

The slider coupling is also known as the metal cross slider coupling. Its slider is circular and made of steel or wear-resistant alloy. It is suitable for the specific size and technical parameters of the cross slider coupling. The speed is low. Transmission with larger torque.The cross slider coupling is composed of two half couplings with grooves on the end faces and a middle disc with convex teeth on both sides.Because the convex teeth can slide in the groove, the relative displacement between the two shafts during installation and operation can be compensated.The slider coupling is composed of two shaft sleeves and a central slider.The center slider is usually made of engineering plastic as a torque transmission element, and other materials, such as metal materials, can be selected under special circumstances.

　　Slider couplingThe material of the parts 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.This kind of coupling is generally used at a speed n<250r/min, where the shaft has greater rigidity and no severe impact.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.As the use time increases, the slider may lose its recoilless function due to wear, but the center slider is not expensive and easy to replace, and it can still play its original performance after replacement.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 center 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.

application
　　Unlike other couplings, the slider coupling does not have an elastic element that can work like a spring, so it will not increase the bearing load due to the increase in the relative displacement between the shafts.In any case, this series of couplings is more worthwhile, and the ability to choose sliders of different materials is the biggest advantage of this coupling.Juren company can provide a variety of raw material center sliders to adapt to different applications according to the specific requirements of customers.Generally speaking, one type of material is suitable for zero-clearance, high-torque rigidity and high-torque situations, and the other type of material is suitable for low-precision positioning, without zero-clearance, but has the functions of absorbing vibration and reducing noise.The non-metallic slider also has excellent electrical insulation and can be used as a mechanical fuse.When the engineering plastic slider is damaged, the transmission effect will be completely terminated, so as to protect the valuable mechanical parts.This design is suitable for large parallel relative displacements.The separate three-part design of the slider coupling limits its ability to compensate for axial deviations, for example, it cannot be used in push-pull applications.At the same time, because the center slider is floating, the two-axis movement must ensure that the slider does not fall off.
