Z3 type swelling inner and outer cone ring

Z1 type expansion coupling sleeve is composed of inner and outer cone rings.The structure is compact and light, suitable for occasions with small installation space.It can be used instead of various key connections or interference fit connections.In order to transmit large loads, multiple pairs of expansion sleeves can be used. The single-sided compression does not exceed 4 pairs of rings, and the double-sided compression can reach 8 pairs of rings, with good centering. ...

The Z2 type expansion coupling sleeve is composed of an open double cone inner ring, an open double cone outer ring and two double cone compression rings. It is tightened with hexagon socket bolts. When tightening, the elastic ring is not axially relative to the hub. Compared with the Z1 type, the radial pressure and the transmitted load can be generated by the same pressing force. ...

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. ...
