Detailed parameters of Z6 type expansion coupling sleeve

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, pulleys, etc.) and shafts to transmit loads. Its function In use, it is divided into two categories: expansion and locking.It is a new type of non-key coupling device that is widely used in the world to realize the connection of mechanical parts and shafts. It is a new type of non-key coupling device that realizes load transmission by tightening the pressure and friction force between the containing surface of the 12.9 grade high-strength screw.

As a kind of advanced basic parts, the expansion coupling sleeve has widely adopted this new technology for mechanical coupling under heavy loads in industrialized countries such as Germany, Japan, and the United States in the XNUMXs.In the connection of the wheel and the shaft, it is a keyless connection device that realizes the load transmission by tightening the high-strength bolts to make the pressure and friction between the containing surfaces realize the transmission of the mechanical parts (such as gears, flywheels, pulleys, etc.) The shaft connection is used to transfer the load.When it is in use, through the action of high-strength 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, it relies on the combined pressure of the expansion sleeve and the mechanical parts and the accompanying friction force. Transmit torque, axial force or a combined load of the two.
