The shape and structure of the cross slide coupling and the slide coupling are similar, and they are suitable for different working occasions.Let me briefly introduce you:
The Oldham coupling is composed of half couplings with grooves on two end faces and an intermediate disc with protruding teeth on both sides.During installation, the convex teeth on both sides of the middle plate are respectively inserted into the grooves of the two halves of the coupling, and the torque is transmitted by the mutual engagement of the groove and the convex teeth.Because the convex teeth can slide in the groove, it has the ability to compensate for the relative offset between the two shafts.
Because the semi-coupling and the intermediate disc form a moving pair, no relative rotation occurs, so the angular velocity of the driving shaft and the driven shaft are equal during operation.However, when working with a relative offset between the two shafts, the middle disk will generate a large centrifugal force, which will increase the dynamic load and wear.During use, lubricate the oil hole of the middle plate before each work of the coupling.
The coupling parts can be made of 45 steel, and the working surface must be heat-treated to increase the hardness; when the requirements are lower, it can also be made of Q275 steel without heat treatment.
Oldham couplings are generally used where the speed is low, the shaft rigidity is large, and there is no severe impact.
Slider couplingThe structure is similar to the cross slider coupling, except that the grooves on the two halves of the coupling are very wide, and the middle plate is modified into a square slider, and it is usually made of cloth-filled bakelite.Due to the small mass and elasticity of the middle square slider, it is allowed to withstand a higher limit speed.The middle sliding block can also be made of nylon, and a small amount of graphite or molybdenum disulfide is added during preparation to make it self-lubricating.The slider coupling is characterized by its simple structure and compact size, which is suitable for occasions with low power and high speed without severe impact.
