The steel grit coupling is the same as the steel ball coupling. The transmitted torque can be adjusted by changing the filling amount of steel grit, which is easy to achieve overload protection.When the working machine is overloaded or stuck, the coupling can automatically slip to prevent the motor from burning out or other important parts from being damaged.
There are many types of couplings, and Oldham couplings and flange couplings are two of them.
There are hundreds of types of gear couplings, but there are two basic forms: 1. Internal gear and external gear combined. 2. End-tooth combination type.Other forms are deformations on these two foundations.
The coupling can choose between automatic reconnection and non-automatic reconnection. It has heat resistance (above 260℃).In addition, certain types of couplings also compensate for the axial, lateral and angular displacement of the shaft.
The coupling originally has the characteristics of high torque rigidity, zero rotation clearance, and elastic body compensation for the radial, axial and angular deviations of the two shafts in the transmission process of the manufacturing machinery, and the clockwise and counterclockwise rotation characteristics are equal.
Since the rubber block in the coupling will be elastically deformed when the torque is transmitted, it can automatically adjust the coaxiality between the motor shaft and the worm shaft within a certain range, so that a large concentricity (tolerance) is allowed during installation. 0.1mm), which is convenient for installation and maintenance. At the same time, the elastic coupling has the effect of slowing down the vibration in the transmission.
