The Z12B type expansion coupling sleeve can combine the shaft hub with a larger fit gap. When disassembling, loosen the bolts to make the connected parts easy to disassemble.When swelling, the contact surface is tightly fitted and not easy to rust, and it is also easy to disassemble.
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.
