Gear couplings are designed to connect coaxial horizontal shafts with angular, radial and axial displacements when transmitting torque from 0.71 to 250 kN · m.

It is a movable joint capable of compensating for angular deviations (for example, friction clutches are inadequate for this). Design toothed couplings consists of two toothed cages, which are connected by bolts, and two toothed bushings, which are inserted into these cages. On clips gear couplings lids with cuffs are also installed. The shafts to be connected are pressed into the holes of the bushings, and the teeth of the bushings (inserted into the cages) mesh with the teeth of the cages. Thus, the transmission of torque to gear couplings ... Caps with cuffs are used to protect the internal parts (teeth) from dust, debris, water. They also help keep the lubricant inside. toothed couplings .

The gear couplings themselves MZ have a high load capacity, which means that they can be used in a fairly wide range of angular velocities and moments. By operating conditions gear couplings not too whimsical. Usually they can withstand up to a day of continuous operation, and for a longer period it is necessary to make short, periodic stops. gear couplings can rotate in any direction with a maximum rotation speed, which must not exceed the speed specified by the manufacturer. Common application gear couplings is a connection of long shafts, for example for conveyor belts. And besides the mentioned alignment compensation, gear couplings are used for automatic control of mechanisms, and also perform some safety functions.
