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.
