cross
Slider couplingIn the structural design and series design, based on the size of the transmission torque, the structure of the coupling and the strength of the hub, determine the range of the shaft hole (the largest and the smallest shaft hole) and the long cross slip of the shaft hole The allowable speed range of the block coupling is determined by calculation according to the allowable linear speed and maximum outer edge size of different materials of the coupling.The allowable speed range of Oldham couplings of different materials, varieties and specifications are different. Changing the material of the coupling can increase the allowable speed range of the coupling. The allowable speed range for steel is greater than the allowable speed for cast iron. Use speed.
Cross slide type shaft coupling is often used in common motors, and can also be used to connect servo motors in some occasions. The relative displacement can be corrected by the sliding of the center slide during use.The slider couplings produced by different manufacturers in the market are not exactly the same.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 semi-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, it should be noted that the working speed should not be greater than the specified value when selecting.
