Cat® Torsion Hub and Coupling is used to connect the engine to the hydraulic pump, and to absorb the torsional vibrations and shocks that occur during operation. They are part of the power train system that transfers the mechanical power from the engine to the hydraulic system, which then powers the drive wheels and the attachments. The torsional hub helps to reduce the noise and vibration from the engine, and to protect the hydraulic pump from excessive torque or speed fluctuations. The torsional hub also allows for some misalignment between the engine and the pump shafts. The coupling is a device that is mounted on the torsional hub, and has a splined connection to the hydraulic pump shaft. The coupling helps to transmit the rotational motion from the engine to the pump, and to accommodate some angular or axial movement between the shafts. The coupling also provides some protection from overload or jamming of the hydraulic system. The torsional hub and coupling are important components of the Cat® Machine's power train system, as they ensure a smooth and efficient transfer of power from the engine to the hydraulic system. They also enhance the durability and performance of the engine and the pump, and prevent damage or failure of the hydraulic system.
