SL cross slide coupling (Q/JL03-2001)

SLOldham coupling(Q/JL03-2001) is composed of two shaft sleeves and a sliding block.The slider as a torque transmission element is usually made of engineering plastics, in which case other materials, such as metal materials, can be selected.The sliding block is connected with the shaft sleeves on both sides by 90° oppositely distributed clamping slots on both sides, so as to achieve the purpose of torque transmission.The sliding block and the shaft sleeve are matched with a slight pressure, which enables the coupling to run with zero clearance during the operation of the equipment.As the use time increases, the slider may lose its recoilless function due to wear. However, the slider is not expensive and is easy to replace. After replacement, it can still exert its original performance.

SL Cross Slider Coupling (Q/JL03-2001) is often used in common motors, and can also be used to connect servo motors in some occasions, and the relative displacement can be corrected by the sliding of the slider 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 at a rotation speed n<250r/min, where the shaft stiffness is relatively large and there is no severe impact.

The SL cross slider coupling (Q/JL03-2001) consists 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 material of this coupling part 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 at a rotation speed n<250r/min, where the shaft stiffness is relatively large and there is no severe impact.

The material of the SL Oldham Coupling (Q/JL03-2001) 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.The Oldham slider coupling is also known as the metal slider coupling. The slider has a circular ring shape and is made of steel or alloy. It is suitable for transmissions with low speed and large transmission torque.
