Belt Conveyor Accessories Expansion sleeve Type Z9 expansion sleeve - lock coupling

Expansion sleeve is an advanced basic component widely used for mechanical connection under heavy load in the world today. In the connection between wheel and shaft, it is a kind of keyless coupling device that realizes load transmission by tightening high strength bolts to make the pressure and friction produced between the containing surfaces.

Expansion sleeve has the following advantages:

1. The use of expansion sleeve makes the manufacture and installation of host parts simple. The machining of the shaft and hole for installing the expansion sleeve does not require the same high manufacturing tolerances as the interference fit. When INSTALLING THE expansion sleeve, THERE is no need to heat, cool or pressurize the equipment, just tighten the bolt according to the required torque. The hub can be conveniently adjusted to the desired position on the shaft. Expansion sleeves can also be used to join poorly soldered parts.

2. Long service life and high strength. The expansion sleeve is driven by friction, which has no keyway to weaken the connected parts, no relative movement, and no wear and tear during work.

3, expansion sleeve in overload, will lose the connection, can protect the equipment from damage.

4, expansion sleeve connection can bear multiple loads, its structure can be made into a variety of patterns. According to the size of the installation load, you can also use multiple expansion sleeve in series.

5, the expansion sleeve disassembly is convenient, and has good interchangeability. Because the expansion sleeve can combine the hub of the shaft with larger clearance, the bolt can be loosened when disassembling, so that the connected part can be easily disassembled. When the expansion is tight, the contact surface is tight and does not rust, and it is easy to disassemble.
