Detailed parameters of SL cross slider coupling
The SL cross slider coupling is also known as the metal slider coupling. It consists of two half couplings with radial grooves on the end faces and a middle slider with a tenon at each end. The two ends of the middle slider are The tenons are 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 concentric or skewed, the slider will slide in the groove during movement, so the groove and the slider Lubricant should be added to the working surface of the shaft. If the two shafts are not concentric, when the speed is high, the eccentricity of the slider will produce a lot of centrifugal force wear and bring additional load to the shaft and shaft. Therefore, it is only suitable for low speed and transmission Large load occasions.

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.
