    Oldham couplingIt consists of two half couplings with grooves on the end faces and one with convex teeth on both sides 
    The middle disk is composed.Because the convex teeth can slide in the groove, the relative displacement between the two shafts during installation and operation can be compensated.The material of the coupling 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 where the speed n<250r/min, the rigidity of the shaft is relatively large, and there is no severe impact.    
    ●The structure of the slider coupling is similar to that of the cross slider coupling, the difference is that the middle cross slider is square sliding. The specific dimensions and technical parameters of the cross slider coupling
    The specific dimensions and technical parameter blocks of the Oldham slider coupling use the middle slider 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 half couplings.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. The relative offset of the two axes must be compensated, 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 direction △α≤ 40'.

    The cross slide coupling is also known as the metal cross slide 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 slide coupling. The speed is low. , Transmission with larger torque.The Oldham 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.
