When you seeking high-precision angular power transmission solutions for space-constrained complex drivetrains, our Bevel Gears deliver core values of compact design, high torque transmission, and low-noise operation, specifically engineered for demanding applications like automotive differentials, construction machinery steering systems, marine propulsion units, and aircraft landing gear. Addressing challenges such as stringent assembly precision requirements, tooth surface stress concentration failures, and prominent vibration/noise under alternating loads, we provide three groundbreaking solutions: 20CrMnTiH carburized alloy straight bevel gears (surface hardness HRC60+, 150% impact-resistant lifespan enhancement), spiral bevel gears (35° optimized helix angle, 50% increased contact area, ≤60dB noise), and zerol bevel gears (axial-force-free design for precision instrument indexing mechanisms).  Utilizing 5-axis closed-loop machining centers (AGMA Class 12 precision) and tooth surface topology modification technology, we achieve 99% transmission efficiency and micron-level meshing consistency. Validated by extreme testing: 100,000 km of operation without abnormal wear in heavy truck differentials, ISO 6336 strength certification for agricultural steering systems, and aircraft gearbox vibration levels below 0.5mm/s. Our bevel gears redefine reliability through innovation-backed performance.
