The structure, dimensions, and installation methods of the Z9 expansion coupling sleeve product (expansion sleeve) are common to similar products, and all comply with ISO standards.Technical instructions and technical performance can meet the requirements of the use of the machine, and at the same time, they are also the basic accessories for domestically produced replacement parts.
Features of Z8 type expansion coupling sleeve: Z8 type locking coupling disc Z8 type expansion sleeve is suitable for coupling the shaft and the parts on the shaft to transmit torque and axial force.The torque Mt and axial force Ft specified in the standard are calculated according to the corresponding screw tension, and the tightening torque of the screw should reach the required rated value in the technical parameter table.
The Z7C expansion coupling sleeve is a keyless coupling device between the shaft and the sleeve. This device can apply a clamping force to the sleeve from the outside to form a mechanical compression fit between the shaft and the sleeve to transmit torque and expand. The tight sleeve itself does not transmit any torque or load.
