1.Engine Timing Synchronization: When used in the 6D114 engine’s timing system, it drives the camshaft gear, ensuring valves open and close at the correct piston positions – preventing valve-piston collision and optimizing fuel combustion.
2.Swing Drive Torque Transfer: In excavator swing assemblies, it meshes with the swing ring gear, transferring torque from the planetary gearbox to rotate the upper structure (cab, boom, bucket) smoothly and precisely.
3.Speed Regulation: Adjusts rotational speed to match component requirements – e.g., reducing high-speed motor input to low-speed swing motion, or synchronizing crankshaft/camshaft speeds.
4.Load Distribution: Even tooth contact distributes high torque across multiple teeth, preventing tooth damage and extending the service life of both the pinion and mating gear.
