The Z5 type expansion coupling sleeve is used for the occasions that transfer large loads and require high centering accuracy.Compared with the Z4 type, the taper of each cone ring is the same, and there is a flange in the middle of the inner ring, which is easy to disassemble. The Z5 type has a longer bonding surface and a smaller taper.
Compared with the Z4 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. The Z4 type expansion sleeve is composed 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.
Z3 type expansion coupling sleeve characteristics: Z3 type expansion inner and outer cone rings are tightened with hexagon socket bolts, which can transmit larger loads, and there is a disassembly threaded hole on a cone ring; Z3 type has a longer joint surface, good neutrality, and is applicable It is used in occasions where high rotation accuracy is required and large loads are transmitted.
