How can I buy the correct ML plum-shaped elastic coupling?

There are two main types of ML plum-shaped elastic couplings, one is the traditional straight claw type, and the other is the curved (inward) claw type zero-backlash coupling.The traditional ML plum-shaped elastic coupling is not suitable for high-precision servo transmission applications.The zero-backlash claw type ML plum blossom elastic coupling is evolved on the basis of the straight claw type, but the difference is that its design can be suitable for the application of the servo system. It is often used to connect servo motors, stepping motors and ball screws. .The curved surface is to reduce the deformation of the elastic plum spacer and limit the influence of centripetal force on it during high-speed operation.The zero-clearance claw coupling is composed of two metal sleeves (usually made of aluminum alloy, stainless steel can also be provided) and a plum blossom elastic spacer.The plum blossom elastic spacer has multiple leaf branches. Like a slider coupling, it also squeezes the plum blossom elastic spacer and the sleeves on both sides to match, and thus its zero clearance performance.Different from the slider coupling, the ML plum-shaped elastic coupling is driven by squeezing while the slider coupling is driven by shear.When using a zero-clearance claw coupling, users should pay attention not to exceed the tolerance of the elastic element given by the manufacturer (under the premise of zero clearance), otherwise the plum elastic spacer will be squashed and deformed and lose its elasticity. The load disappears, resulting in the loss of zero-gap performance, and the user may only find out after a serious problem occurs.

The ML plum-shaped elastic coupling is suitable for balance performance and high-rotation applications (30000 rotations per minute), but it cannot meet the axial deviation.The greater the eccentricity and deflection angle, the greater the bearing load.Another value of concern is the failure of the ML plum-shaped elastic coupling.When Mei's elastic spacer is damaged or ineffective, the torque transmission will not be interrupted, and the metal nails of the two shaft sleeves bite, and the torque transmission continues, which may cause problems to the system.One of the main advantages of this coupling is that the appropriate plum elastic spacer material is selected according to availability.In addition, some automation companies also provide plum spacers made of various elastic materials.In addition, different hardness and temperature can help customers choose the right material to meet the usability performance standards.
