711-67-11662 COUPLING COMPLETE

This is the most critical application part of the coupling assembly. For example:
In a mechanically driven bulldozer, the engine flywheel is connected to the input shaft of the gearbox through a rubber elastic coupling assembly. The rubber component buffers the vibration of the engine, compensates for the installation deviation between the flywheel and the gearbox shaft, and ensures smooth power transmission to the gearbox.
In a fully hydraulic bulldozer, the engine is connected to the transfer case through a coupling assembly, which then distributes power to the walking hydraulic pump, working device hydraulic pump, etc. The coupling needs to adapt to the composite load and shaft displacement when multiple pumps are driven.

The hydraulic system of bulldozers (such as the main pump and steering pump) is usually driven by the engine or transfer case, and the coupling assembly is used to connect the drive shaft and the hydraulic pump input shaft. For example:
The drive end of the gear pump or plunger pump is connected to the output shaft of the transfer case through an elastic coupling, which avoids pump body wear caused by the pump shaft not being concentric with the drive shaft, and reduces the transmission of vibration during pump operation to the engine.
