The tooth coupling needs to simplify the mechanical models of the moment of inertia and stiffness of the active and driven sides in the transmission shaft system. Typically, it is simplified into two equivalent disks arranged on both sides of the coupling. To avoid resonance, change the frequency of cyclic load changes or the frequency of shaft system changes. Periodic load is a typical form of load in mechanical transmission for gear couplings during operation.

It is difficult for us to achieve this by changing the moment of inertia, while the stiffness of the shaft system is easily altered. The toothed coupling does not require lubrication and requires less maintenance work, and can operate continuously for a long time. The elastic spacer has multiple blade branches, otherwise the elastic spacer will be flattened, deformed, and lose its elasticity, and the pre load will disappear. After overall heat treatment, it has sufficient mechanical strength. One type of claw plate is a casting, which eliminates processing losses.

The main form of failure of toothed couplings is the use of metal teeth as elastic components, which have a large load transfer capacity, and there are no non-metallic components in the entire product. There is no relative movement between components, no friction or wear, so lubrication is not required, which is in line with the development direction of oil-free process equipment. The angular and axial stiffness are low, so the additional axial force and additional bending moment are very small.

Gear couplings have the functions of shock absorption and angular, axial, and radial displacement compensation. In fact, the way in which gear couplings transmit torque is similar. In addition to applying appropriate sealant or adding sealing gaskets to the static sealing area, a sealing ring should also be installed at both ends of the inner gear ring for sealing between the inner gear and the outer gear ring, with a long service life.
