The characteristics of rigid couplings: rigid couplings have light weight, low inertia and high sensitivity. In practical applications, rigid couplings are easy to maintain and oil-resistant.And in a high-speed environment, it can compensate for the relative displacement caused by high-speed operation.Of course, if the relative displacement can be successfully controlled, it can also perform very well in the servo system.
The surface roughness of the coupling refers to the small spacing and small peak and valley unevenness of the machined surface.The distance (wave distance) between the two wave crests or two wave troughs is very small (below 1mm), and it is difficult to distinguish with the naked eye, so it belongs to the microscopic geometric shape error.The smaller the surface roughness, the smoother the surface.
