The Z12A type expansion coupling sleeve is easy to disassemble and has good interchangeability.Since the expansion sleeve can combine the shaft hub with a larger fit gap, the bolts are loosened when disassembling, so that the connected parts can be easily disassembled.
Compared with the Z11 type, the Z2 type expansion coupling sleeve has a long joint surface and high centering accuracy. It is used in the occasions where the rotation accuracy is higher and the transmission of larger loads is required.It consists of a split double cone inner ring with different tapers, a split double cone outer ring and two double cone compression rings, which are locked with hexagon socket bolts.
The Z10 type expansion coupling sleeve is suitable for the keyless coupling device between the shaft and the sleeve. It can apply clamping force to the sleeve from the outside to form a mechanical compression fit between the shaft and the sleeve, and transmit torque. The expansion sleeve itself does not Transmit any moment and load, easy to install and disassemble.
