Excavator Spare Part Swing Gearbox Speed Reducer Swing Drive K1000350

This heavy-duty high-precision rotary reducer assembly (rotary gearbox/rotary drive) has a core original part number of K1000350. This assembly serves as the core transmission axis for the 360 ° rotation of the excavator body, perfectly adapting to the large and medium-sized main crawler excavator series. The product is designed with a multi-stage planetary gear transmission structure based on first principles, and the tooth surface adopts high-strength carburizing and quenching technology to bear the extreme shear force and impact load caused by high-frequency reversing, ensuring absolute certainty of torque output. The physical dimensions of the product packaging are approximately 580mm × 580mm × 690mm, with an overall net weight of approximately 165kg. The original factory standard position is precisely connected and seamlessly replaced.

"Extreme obstacle clearance and heavy load fastening: Before lifting and docking, the installation surface of the frame and the large gear ring of the slewing support must be thoroughly cleaned to ensure that the surface is free of rust and foreign objects. All high-strength fastening bolts must be coated with anti seize compound and tightened symmetrically and in stages using a torque wrench in strict accordance with the original factory standard torque.

Gear meshing and alignment (core avoidance pit): During installation, it is necessary to adjust the meshing clearance between the output gear of the reducer and the large gear ring of the slewing support, and apply a sufficient amount of special heavy-duty lubricating grease on the tooth surface. When restoring the connection of the rotary motor, it is necessary to check that the motor drain pipe is unobstructed.

No load micro transition: After installation, gear oil must be added to the standard line first. After the first ignition, control the vehicle body to rotate slowly at small angles left and right alternately for 10-15 minutes in an unloaded state. Only after confirming that the planetary gears are operating without abnormal noise and the thermodynamic state is stable can full working load be applied."
