Helical Gear Box
The BHT-Series Modular Gear Units from Bhagirath Heavy Transmission are engineered with cutting-edge technology and decades of manufacturing expertise. Designed under the modular design principle, our gearboxes offer high efficiency, compactness, and easy serviceability—ideal for demanding industrial applications.
Design & Construction Highlights
- Modular Design Principle:
Gear sizes, transmission ratios, and dimensions follow standard series for efficient mass production and rapid delivery cycles. - Material & Build:
- Gear components are made from case-hardened steels of highest strength
- Housings are constructed from vibration-damping grey cast iron and MS Steel Plate Fabricated duly stress Relived
- Bearings are amply dimensioned for long service life
- Gear profiles include ground helical gears and lapped spiral bevel gears for smooth, quiet performance
- Machining & Quality Control:
Manufactured using state-of-the-art CNC machines and continuously monitored through high-precision measuring instruments to ensure perfect alignment and tolerance.
