1、Expansion coupling sleeve (referred to as expansion sleeve), is widely used in today's international heavy loads under the mechanical coupling of an advanced basic components, in the wheels and shafts of the coupling, it is by tightening the high-strength bolts to make the production of pressure and friction between the inclusive surface of the realization of the load transfer of a keyless coupling device.
2、Easy to dismantle, stable process, easy to dismantle, easy to maintain
3、Tight design, excellent design, more excellent product technology.
4、Stable performance, excellent production process, to ensure excellent performance.
5、Long service life, high strength, tightening sleeve rely on friction transmission, no keyway weakening of the coupled parts, no wear and tear in the work.
6, good protection performance, tightening sleeve and then overloaded, will lose the linkage, can protect the equipment from damage.
7, structural diversity, tightening sleeve coupling can withstand multiple loads, its structure can be made into multiple styles, but also more tightening sleeve series use.
8, the tightening sleeve installation without heating, cooling and pressurization equipment, only the bolt required to tighten the torque can be, and the bolt required to tighten the torque can be, and the tightening sleeve can be used in series. It is only necessary to tighten the bolts to the required torque, and it is easy to adjust.
