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.
The basic dimensions and parameters of the Z6 expansion sleeve:
A basic size (mm) Dimensions | Rated load | Socket head cap screws |
Pressure on joint surface between expansion sleeve and shaft pt N / mm2 |
Pressure on the joint surface between expansion sleeve and wheel load pt N / mm2 |
