Coupling encoder is mechanical transmission is mainly used to connect the shaft and the shaft, and other rotary parts, to transmit motion and torque, sometimes common parts can be used as a safety device, operation of the machine, the axis of the two can not be separated; only in the machine parking and open the connection, the two axes can be separation.

The coupling is a mechanical part with the purpose of passing the torque or the rotation angle, but it has different characteristics. Please select the correct coupling series according to the required characteristics, and then determine the pore size, size and parameters.

Positioning screw fixation: two positioning screws clearance 90 degrees on the fixed axis locking, is one of the most simple way to fix. As the front end of the screw and the axis of direct contact, may cause damage or removal of the axis of the axis.

The clamping screws tightening using six angle bolt strength, the cracks will shrink, and tightly clamp the axis. This way of fixing and removing is very convenient, will not cause the damage of the axis, is a very common way of fixing.

Key: fixed hole coupling with easy axis coupling and keyway, more tightly bite. It is suitable for high torque transmission and prevents axial sliding, which is usually matched with a positioning screw and a clamping screw.

Compound fixed: fixed shaft coupling, the use of two or more of the fixed method is known as the compound fixed.

Rotary encoder is a set of machine, light, electric precision technology in one of the high-tech crystal, through the photoelectric conversion, the output shaft can be the angular displacement, angular velocity and other mechanical parameters into the corresponding electric pulse with digital output.
