The working principle of the slider coupling and the introduction of raw materials

Many people have heard of couplings, but do not know the working principle of the coupling and what the original information is. The following is the relevant content brought by the editor, and I hope that we can have a harvest!

Operating principle and structure of slider coupling

The slider of the slider coupling uses nylon square blocks as the elastic body, and the center slider is used to slide in the corresponding radial grooves on the end faces of the two halves of the coupling to complete the coupling of the two halves.This coupling has high noise, low power and fast wear. Generally, it is not used as much as possible. As long as the rotation speed is very low, the slider coupling specified in this specification is suitable for oil pump equipment or other occasions with small transmission torque. The relative offset of the two axes must be compensated, and the function of shock absorption and cushioning; its operating 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'.  
Cross slider coupling is also called metal slider coupling. Its slider is ring-shaped and made of steel or wear-resistant alloy. It is suitable for transmission cross slider couplings with low speed and large transmission torque. The device consists of two half couplings with grooves on the end faces and a center plate with convex teeth on both sides.Because the convex teeth can slide in the groove, the relative displacement between the two shafts during the device and operation can be compensated.The material of this kind of coupling parts can be made of 45 steel, and the work surface needs heat treatment to improve its hardness; when the requirements are lower, Q275 steel can also be used without heat treatment.In order to reduce conflict and wear, oil should be injected from the oil hole of the center plate for smoothness during use.Since the half-coupling and the central disc form a moving pair and cannot produce relative rolling, the angular velocity of the driving shaft and the driven shaft should be equal.However, when working with relative displacement between the two shafts, a large centrifugal force will be generated on the center plate, which will increase the dynamic load and wear.Therefore, when selecting, it should be noted that the operating speed should not be greater than the regulated value.This kind of coupling is generally used for speed n<250r/min, the rigidity of the shaft is large, and there is no severe impact.   
      
    　　The slider coupling is not like other couplings. It does not have an elastic element that can work the same as a tension spring, so it will not increase the bearing load due to the increase of the relative displacement between the shafts.In any case, this series of couplings are more worthwhile, and the ability to choose sliders with different materials is the advantage of this coupling.Juren can provide a variety of original data center sliders to choose from according to the specific requirements of customers to get used to different uses.Generally speaking, one type of material is suitable for zero gap, high torque rigidity and high torque, and the other type of material is suitable for low-precision positioning, without zero gap, but has the function of absorbing sensation and reducing noise.The electrical insulation effect of the non-metallic slider can be used as a mechanical fuse.When the engineering plastic slider is damaged, the transmission effect will be completely stopped, and then the valuable mechanical parts will be maintained.This planning is suitable for large parallel relative displacements.The three-part design of the split slider coupling restricts its ability to compensate for axial errors. For example, it cannot be used in push-pull applications.At the same time, since the center slider is floating, the two-axis movement is necessary to ensure that the slider does not fall.
The material of the sliding block coupling parts can be made of 45 steel, and the appearance of the operation requires heat treatment to improve its hardness; Q275 steel can also be used when the requirements are lower, without heat treatment.In order to reduce conflict and wear, oil should be injected from the oil hole of the center plate for smoothness during use.Since the half-coupling and the central disc form a moving pair and cannot produce relative rolling, the angular velocity of the driving shaft and the driven shaft should be equal.However, when working with relative displacement between the two shafts, a large centrifugal force will be generated on the center plate, which will increase the dynamic load and wear.Therefore, when selecting, it should be noted that the operating speed should not be greater than the rule value.This kind of coupling is generally used for speed n<250r/min, the rigidity of the shaft is large, and there is no severe impact.The central sliding block is connected to the shaft sleeves at the two ends through the clamping grooves at the two ends that are 90° relative to each other, and then reaches the intention of transmitting torque.The center sliding block and the shaft sleeve are matched with a small pressure, which can make the coupling have zero gap operation in the equipment operation.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 perform its original function after replacement.Slider couplings are often used in common motors, and can also be used to connect servo motors on a single occasion, and the relative displacement can be corrected by the sliding of the center slider during use.Since it is the conflicting force between the slider and the sleeve that opposes the relative displacement, the bearing load between them will not increase due to the addition of the relative displacement.
