The working principle of the slider coupling

　　The slider of the slider coupling uses nylon square blocks as the elastic body, and the middle slider is used 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.This coupling has high noise, low efficiency and fast wear. Generally, it is not used as much as possible. It is only used for occasions with very low speed. The slider coupling specified in this standard is suitable for oil pump devices or other occasions with small transmission torque. Compensate the relative offset of the two axes, shock absorption and cushioning performance; its working temperature is -20~70°C.The nominal torque transmitted is 16~500N.m.Allowable compensation amount: axial △ x=1~2mm, radial △ y ≤ 0.2mm, angular △α≤ 40'. 

　　Unlike other couplings, the slider coupling does not have an elastic element that can work like a spring, so the bearing load will not increase due to the increase in the relative displacement between the shafts.In any case, this series of couplings are more worthwhile, and the ability to choose sliders of different materials is a big 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 the electrical insulation function, which can be used as a mechanical fuse.When the engineering plastic slider is damaged, the transmission effect will be 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 ensures that the slider will not fall off.

　　As the use time increases, the slider may lose its recoilless function due to wear, but the center slider is not expensive, and it is easy to replace, and it can still play its original performance after replacement.Slider couplings are often used in common motors. In some cases, they can also be used to connect servo motors. The sliding of the center slider is used to correct the relative displacement 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.
