The elastic spacer has multiple blade branches, and the Flexible Coupling makes the elastic spacer fit with the shaft sleeve on both sides through extrusion, thus ensuring its zero-gap performance. The Flexible Coupling is driven by squeezing, while the slider quincunx Flexible Coupling is driven by shearing force. The elastic spacer will lose its elasticity due to flattening and deformation, and the preload will disappear, resulting in the loss of zero clearance performance. It may also be found after the problem occurs. When replacing wearing parts, the Flexible Coupling needs to be moved axially to compensate for the relative deviation of the two shafts.
The Flexible Coupling is mainly composed of two convex teeth that are closely meshed and subjected to radial extrusion to transmit torque. When the two axes are relatively offset, the elastic element will have corresponding elastic deformation, which plays the role of automatic compensation. Flexible Coupling is mainly applicable to working occasions with frequent starting, positive and reverse rotation, medium and high speed, medium torque and high reliability requirements, such as metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, textile, water pump, fan, etc. The flexible coupling works stably and reliably, has good damping, buffering and electrical insulation performance, and has large axial, radial and angular compensation capacity.
Flexible Couplings has simple structure, small radial size, light weight and small moment of inertia, and is suitable for medium and high speed applications. High-strength polyurethane elastic element is wear-resistant and oil-resistant, with large bearing capacity, long service life, safe and reliable. Flexible Coupling requires no lubrication, less maintenance work, and can operate continuously for a long time. The Flexible Coupling plays a vital role in the service life. The polyurethane elastomer used in the Flexible Coupling has elasticity and wear resistance.
Flexible Coupling has the advantages of stamping resistance, oil resistance, etc. In some cases, the elastomer material can also be nylon or nitrile rubber. The material of Flexible Coupling is generally steel or cast iron, and can also be aluminum alloy or nylon. The Flexible Coupling has the characteristics of compensating for the offset of two shafts, damping, buffering, small radial size, simple design, no need to be smooth, high bearing strength, and convenient maintenance. It is suitable for connecting two coaxial lines, the forward and reverse directions are capricious, and the standard operation is reliable. The elastic components of the Flexible Coupling are made of polyurethane and cast nylon. Different materials are selected according to different environments.
