Pump Replacement Rubber Excavator Coupling 11nb-13011 For Hyunday R480LC-9S

It is a rubber part used in a mechanical drive shaft train that connects two shafts or shafts with slewing parts. It plays the role of transmitting motion and power, and has functions such as compensating for the relative displacement of the two axes and cushioning shock absorption. Unlike other shock absorption products, it is mainly used to attenuate the torsional vibration of the drive shaft system, while other products mainly attenuate mechanical linear vibration. According to the force, rubber elastic couplings can be divided into compression type and shear type. According to the structural use, the former has rubber sleeve pin coupling, rubber plate coupling, plum blossom elastic coupling, universal elastic coupling and air spring coupling and other varieties; The latter has rubber-metal ring couplings, tire couplings, and U-shaped rubber couplings. Such products have small modulus, large elastic deformation, can withstand loads in different directions, and have small damping, and are widely used in vehicles, ships and various machinery. Excellent absorption of vibration and shock and reduced noise from mechanisms. The rubber part of the elastomer consists of polygonal rubber and aluminum filled with its apex, each of which is firmly vulcanized and bonded together. The rubber body is bolted with the cylinder bushing and flange bushing respectively, and the transmission is carried out through the rubber body. In particular, the radial bolted connection is a pre-deformed rubber body connected to the cylinder bushing, so it is a pre-compression structure with excellent flexibility, and can be transmitted with excellent absorption of vibration and shock.
