Z9 Type Expansion Connecting Sleeve

Compared with the Z5 type, the Z4 type expansion coupling sleeve has the same taper of each cone ring, and there is a flange in the middle of the inner ring, which is easy to disassemble. The Z5 type has a longer joining surface and a smaller taper, which is used in occasions that transfer larger loads and require higher centering accuracy. ...

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. ...

The Z8 type expansion coupling sleeve transmits large torque for a long time during work, which is easy to cause fatigue and deformation of the metal, causing fatigue and wear between the expansion sleeve and the fastener. At the same time, the sintering machine is generally large, which makes it difficult.In response to such problems, polymer composite materials can be used for on-site...
