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.
The Z2 type expansion sleeve is composed of an open double cone inner ring, an open double cone outer ring and two double cone compression rings. In order to facilitate disassembly, the Z2 type expansion sleeve has screw holes for disassembly on a compression ring, with a total of 2 to 4 points along the circumference.
The 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 transfer larger 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, and the neutrality is good.
