Product Characteristics
High-rigidity Vibration-damping HT250 Cast Iron Housing
Integrally cast housing made of HT250 grey cast iron with dense internal reinforcing ribs and uniform thick wall. The natural vibration absorption characteristic of cast iron absorbs impact vibration during equipment start and stop, compatible with full-range industrial reduction transmission scenarios such as mixing, conveying, lifting and metallurgy.
Carburized & Hardened Precision Gear Sets in 20CrMnTi
Gears are made of 20CrMnTi alloy steel with deep carburizing and quenching, maintaining tooth surface hardness of 58-62HRC. Spur gears reach Grade 6 precision and bevel gears Grade 7 after precision grinding, with wide meshing surface to resist fatigue and long-term alternating loads.
Modular Heavy-duty Matching Transmission Components
The output main shaft is forged from tempered 40Cr alloy steel. Two bearing options are available: standard domestic heavy-duty HRB, LYC, ZWZ bearings, and upgraded imported SKF bearings. Double-layer Taiwan oil seals on shaft ends plus housing surface sealant build a multi-layer protection system against dust and oil leakage.
Product advantages
Grading High Transmission Efficiency with Lower Energy Loss
2-stage reduction gearbox achieves 96% efficiency, and 3-stage model stably reaches 94%. Minimal meshing clearance of precision gears cuts power loss greatly, reducing overall power consumption and factory operating costs during long-hour continuous operation.
Low Temperature Rise & Ultra-quiet Operation for Multiple Working Conditions
Temperature rise ≤40℃ under no load, maximum temperature rise limited within 55℃ under full load, and overall operating noise ≤65dB. Smooth gear meshing greatly eliminates transmission resonance, enabling stable operation in high-temperature, dusty and round-the-clock workshops, complying with environmental noise reduction standards.
100% Full Pre-shipment Inspection & Long-term Anti-leakage Guarantee
Every reduction gearbox undergoes extended no-load and full-load running inspection before delivery. The precisely milled housing joint surface and optimized anti-sling oil shaft structure fundamentally eliminate common oil seepage and leakage defects under high-pressure operation.

FAQ
Q: What extra protection upgrades are available for dusty and humid working conditions?
A:Reinforced dust baffles, water-resistant fluororubber oil seals and thickened anti-corrosion paint coating for housing are optional, which effectively block erosion from moisture, mineral dust and mud.
Q:Are multiple output flange sizes available for one gearbox model?
A:Custom non-standard flanges, vertical bases, torque arms and other mounting accessories are supported to match connection dimensions of motors, mixers, conveyors and other machinery.
Q:What causes slight vibration during gearbox operation and how to fix it?
A:Standard ratios range from 3 to 100. Three-stage gear transmission structure is adopted for ultra-large speed ratios, delivering higher torque output for low-speed heavy-duty driving equipment.
