    Tips: Shaft coupling types

    Shaft couplings can be divided into two categories: rigid couplings and flexible couplings.

    Rigid couplings do not have the ability to buffer and compensate for the relative displacement of the two axes, and require strict alignment of the two axes. However, this type of coupling has simple structure, low manufacturing cost, convenient assembly and disassembly and maintenance, and can ensure that the two axes have high The neutrality of the, the transmission torque is large, and it is widely used. Commonly used are flange couplings, sleeve couplings and clamp couplings.

    Flexible couplings can be divided into flexible couplings without elastic elements and flexible couplings with elastic elements. The former type only has the ability to compensate the relative displacement of the two axes, but it cannot buffer and reduce vibration. The common ones are slippery. Block couplings, gear couplings, universal couplings and chain couplings, etc. The latter type contains elastic elements, which not only has the ability to compensate for the relative displacement of the two axes, but also has buffering and damping functions. However, the transmitted torque is limited by the strength of the elastic element, and is generally not as good as the flexible coupling without elastic elements. Commonly used are elastic sleeve pin couplings, elastic pin couplings, plum-shaped couplings, and tire-type couplings. Couplings, serpentine spring couplings and reed couplings, etc.

    Existing reviews of One Diaphragm Coupling, 5mm to 10mm
    Thoroughly impressed with its performance
    The coupling has a simple design but offers excellent torque transmission and vibration-damping capabilities. I especially appreciate how easy it was to install and how smoothly it runs. Highly recommend!

    High quality CNC coupling
    Buying this good single diaphragm coupler saved me a fortune, easy to install, I use the coupler to drive the ballscrews on my CNC mill, don't worry, it's sturdy and should last a long time.
