Product Details

Z11 type expansion coupling sleeve positioning, simple hub hole, wide application.Has good interchangeability.Since the expansion sleeve can combine the shaft hub with a larger matching gap, the bolts are loosened when disassembling, and the connected parts can be easily disassembled.When swelling, the contact surface is tightly fitted and not rusted, and it is also easy to disassemble.

The Z11 type expansion coupling sleeve is a keyless coupling device. Its principle and purpose are to generate a huge holding force between the inner ring and the shaft, and between the outer ring and the hub through the action of the tension bolt, so as to realize the mechanical and The keyless connection of the shaft.When under load, torque, axial force or the combined load of the two are transmitted by the combined pressure of the expansion sleeve and the machine parts and shaft and the accompanying friction force.The expansion sleeve connection mainly has the following advantages: centering; easy installation/adjustment/disassembly; stable connection; it can protect the equipment from damage when overloaded, especially suitable for transferring heavy loads.It is widely used in heavy machinery, wind power generation, packaging machinery, printing machinery, CNC machine tools, automation equipment, etc.

Compared with the Z11 type, the Z2 type expansion coupling sleeve has a long joint surface and is centered. It is used in the occasions that require high rotation accuracy and transmit large loads.It 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.
