Large Slewing Ring Gear for CNC Machinery

Slewing ring gear

Our large ring gears are made of high-quality 42CrMo alloy steel sourced from qualified regular manufacturers, with traceable and reliable raw materials. Featuring excellent hardenability, high strength, superior toughness, outstanding fatigue and impact resistance, 42CrMo steel has stable low-temperature performance and no obvious temper brittleness, ensuring reliable load capacity and long service life of large-diameter ring gears. We adopt a complete set of mature processes including precision forging, finish machining, and tooth surface intermediate frequency quenching. All finished products undergo strict hardness testing and full-dimensional precision calibration. With accurate tooth profiles, tight tolerances and uniform hardness, our ring gears effectively avoid common defects such as processing deformation, abnormal wear, transmission jamming and precision attenuation.

Features & performance advantages

To solve the industry pain points of large 5-meter ring gears such as difficult precision control and easy deformation, we adopt customized tooling, segmented precision processing and overall calibration technology, combined with multiple stress relief aging treatments to strictly control product flatness, coaxiality and assembly accuracy. Our ring gears operate stably with low vibration, low noise and low power loss, effectively improving the overall machining accuracy and operational stability of precision machine tools and reducing long-term equipment maintenance costs.

FAQ

1. What is the service life and wear resistance of large-diameter ring gears? Are they suitable for continuous heavy-duty working conditions?

Our 5-meter large-diameter ring gears are made of high-quality 42CrMo alloy steel. With uniform tooth surface hardness and controllable hardened layer depth, the products feature excellent wear resistance, pitting resistance and spalling resistance. After professional stress relief and stabilization treatment, the ring gears can adapt to severe working conditions such as 24-hour continuous heavy load, alternating load and frequent start-stop operation. They greatly reduce failures including tooth surface wear, tooth breakage and fatigue damage, with a significantly longer service life than ordinary ring gears, fully meeting the long-term service requirements of heavy-duty precision machine tools.

2. Do you support matched machining of ring gears to fit original host equipment?

We provide precision matched machining services for gears and ring gear sets. According to customers’ original equipment parameters, old part mapping data, installation benchmarks and meshing clearance requirements, we conduct targeted customized processing in strict accordance with original factory assembly standards. All matched products adopt unified precision grades and heat treatment parameters, featuring smooth meshing, stable transmission, low noise and controllable backlash, which can perfectly match various heavy-duty precision machine tools and replace original parts.
