Slider coupling

SliderCouplingThe 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 low, without heat treatment.

  SliderCouplingThe 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 rotation speed n<250r/min, where the shaft stiffness is relatively large and there is no severe impact.
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 are more value-for-money, and the ability to choose sliders of different materials is the general trend of this coupling.Juren can provide a variety of raw material 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-degree positioning, without zero-clearance, but has the functions of absorbing vibration and reducing noise.The non-metallic slider also has a good electrical effect 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 slider is floating, the two-axis movement must ensure that the slider does not fall off.
