    name:

    Z6 type expansion coupling sleeve

    description:The main purpose of Z6 type expansion coupling sleeve (referred to as expansion sleeve) is to replace the coupling effect of single key and spline to realize the coupling of mechanical parts (such as gears, flywheels, belt pulleys, etc.) and shafts to transmit loads. Its function In use, it is divided into two categories: expansion and locking.
    Detailed introduction:

    Z6 type expansion coupling sleeveThe main purpose of (referred to as the expansion sleeve) is to replace the connection of single keys and splines to realize the connection of mechanical parts (such as gears, flywheels, belt pulleys, etc.) and shafts to transmit loads. Its function is divided into expansion during use. Two categories with locking.

    Expansion coupling sleeve as a kind of basic parts, industrially developed in the XNUMXs, such as Germany, Japan, etc., widely adopted this for mechanical coupling under heavy loads.In the connection of the wheel and the shaft, it is a keyless connection device that realizes the load transmission by tightening the bolts to make the pressure and friction between the containing surfaces realize the connection between the mechanical parts (such as gears, flywheels, pulleys, etc.) and the shaft. Connection to transfer load.When it is in use, through the action of bolts, a huge holding force is generated between the inner ring and the shaft, and between the outer ring and the hub; when under load, the torque is transmitted by the combined pressure of the expansion sleeve and the mechanical part and the accompanying frictional force. , Axial force or the combined load of the two.
