SL cross slider coupling

SL cross slider couplingAlso known as metal slider coupling, it is a type of cross slider coupling. The SL cross slider coupling has two half couplings with radial grooves on the end faces and a tenon at each end. The two ends of the middle slider have tenons perpendicular to each other, and they are respectively embedded in the grooves of the two half couplings to form a moving pair. If the measuring axis is not centered or skewed, the slider will move Sliding in the groove, so the groove and the working surface of the slider should be lubricated. If the two shafts are not concentric, when the speed is high, due to the eccentricity of the slider, a large amount of centrifugal wear will be generated, and the shaft and The shaft brings additional load, so it is only suitable for low-speed, high-transmitted load occasions.

The material of the SL cross slider coupling is 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 of the SL cross slider coupling and the intermediate disc form a moving pair, which 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.

SL十字滑块联轴器一般用于转速n<250r/min,轴的刚度较大，且无剧烈冲击处。SL十字滑块联轴器许用补偿量：轴向△ x=1~2mm，径向y≤0.04d(d为轴径），角向α≤40′转速一般不超过300r/min。
