Z9 Type Expansion Connecting Sleeve
The structure, dimensions and installation method of Z9 type expansion sleeve products (expansion sleeve) are common to similar products, and all comply with ISO standards.Technical instructions and technical performance can meet the requirements of the use of the machine, and are also basic accessories for domestically produced replacement parts.
The Z9 type expansion sleeve is often used for the connection of the belt conveyor drive roller body. The principle and purpose of the Z9 type expansion sleeve is 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 keyless connection of the machine and the shaft.When under load, the 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 the shaft and the associated frictional force.
Z9 type expansion sleeve mainly has the following advantages: centering; convenient installation/adjustment/disassembly; stable connection; it can protect the equipment from damage when overloaded, especially suitable for transferring heavy loads.Widely used in heavy machinery, light industry machinery, food machinery, packaging machinery, textile machinery, printing machinery, CNC machine tools, automation equipment, etc.
