High flexible And Torsional Vibration Resistance Excavator Coupling For Flywheels Of Internal Combustion Engines
Excavator Coupling is used to connect the internal combustion engine to the hydraulic pump. It consists of three parts: iron core, elastomer and movable aluminum block. The torsion shaft coupling has simple structure and is easy to install and maintain. The high elastic element is made of synthetic rubber, which can absorb impact and impact. In addition to oil resistance and high temperature resistance, it also features insulation and noiseless operation. In the process of transmitting torque, it will not produce loads detrimental to the machine.
Excavator Coupling used to connect two shafts together at both ends to transmit power. Change the vibration characteristics of the rotating unit. Connect the drive and driven components. Introduce overload protection. Provide conditions for shaft connection of separately manufactured devices (such as motors and generators) and disconnection conditions for repair or modification. Provide shaft misalignment. Introduce mechanical flexibility. Reduce impact load transfer from one shaft to another. Sliding when overloaded.
