Bevel Gears

Bevel Gears

锥齿轮

Bevel gears are used for power transmission between intersecting shafts, typically at a 90° shaft angle. Gyan Drive produces straight bevel gears, spiral bevel gears, and conjugate internal gears. Batch production at GB Class 4~5 precision with gear milling and grinding capabilities. Straight bevel gears offer simple structure and low cost; spiral bevel gears provide smooth meshing, high load capacity, and low noise.
