The expansion sleeve is a kind of advanced basic parts which is widely used in the heavy load mechanical coupling in today's international, in the wheel and shaft coupling, it is a kind of keyless coupling device by tightening the high strength bolt to make the pressure and friction produced between the inclusive surface to achieve the load transmission.
●
High strength, tightening sleeve relies on friction transmission, no keyway weakening of the linked parts, no wear and tear in the work.
●
Tensioning sleeve again when overloaded, will lose the linkage, can protect the equipment from damage.
●
The tightening sleeve coupling can bear multiple loads, its structure can be made into multiple styles, but also more than one tightening sleeve in series use.
●
No heating, cooling or pressure-reducing equipment is required for the installation of the tightening sleeve, only the torque required for the bolts can be tightened, and it is easy to adjust.
