胀紧联结套是如今市场上广泛用于重型载荷下机械联结的一种先进的基础部件，在轴和轮的联结中，它是靠拧紧高强度螺栓使包容面间产生的压力和磨察力实现复核传送的一种装置。 Heave tight coupling sleeve are widely used in heavy load,it is the mechanical coupling of an advanced base parts. In the coupling of shaft and the wheel, it is a keyless connection device that relys on tight high strength bolt the tolerance between the pressure and friction load transmission.
