Henan SL cross slide 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.

Oldham couplingThe material of the 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.Oldham slider coupling is also known as metal slider coupling. Its slider is ring-shaped and made of steel or alloy. It is suitable for transmissions with low speed and large transmission torque.The Oldham coupling is composed of two half couplings with grooves on the end faces and an intermediate disc with protruding 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.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, pay attention to the working speed not greater than the specified value when selecting.This kind of coupling is generally used for speed n<250r/min, the rigidity of the shaft is relatively large, and there is no severe impact.
