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.Tighten with hexagon socket bolts. The elastic ring does not move axially relative to the hub during tightening. Compared with the Z1 type expansion coupling sleeve, the same compression force can generate large radial pressure and transmit large loads.In order to facilitate disassembly, there are screw holes for disassembly on a compression ring, and there are 2 to 4 holes along the circumference.The locking coupling plate is widely used in packaging, printing, textile, machine tools and other machinery. The working principle of the Z2 type expansion coupling sleeve: using the principle of the cone surface, by adjusting the axial displacement of the cone surface, the radial expansion is achieved; it has many characteristics such as large transmission torque, convenient disassembly and assembly, and reusability; the above characteristics make up for the key connection Many shortcomings, this product is a good choice to replace the key; a variety of metric or inch size outer and inner diameter to choose from; compared to the key connection, it can ensure that there is no gap in the transmission, and the service life is extremely long. Basic size (produced according to JB/T 2-7934)
