Z6 Expanding sleeve is a kind of mechanical coupling components, compared with Z2 type, it is more suitable for transmitting torque and axial load larger occasions.
Z6 expansion sleeve structure is more unique, in the outer ring and the inner ring between the inner and outer pressure ring, inner and outer pressure ring outer wall is a slope, the bottom of the slope of the two rings are opposite, the outer ring of the inner wall, the inner ring outer wall are convex, and the pressure ring of the outer wall of the concave shape of the mutual compensation, the inner and outer ring are notched. When the bolt is tightened, the inner and outer pressure rings move relative to each other, and under the action of the slope, the inner ring shrinks and the outer ring expands outward, thus realizing the coupling of the shaft and hub.
This type of expansion sleeve has many advantages. When installing, no heating, cooling or pressurizing equipment, just tighten the bolts as required, and easy to adjust the position of the hub on the shaft. It relies on friction transmission, no keyway weakening to the coupled parts, and no relative motion, long service life and high strength. At the same time, in overloading can lose the role of the linkage, to protect the equipment from damage, easy to disassemble, the contact surface close fit is not easy to rust and corrosion, good interchangeability.
