Bevel Helical Gearbox is a type of gearbox that uses bevel gear stage at the input and the output of bevel stage is internally connected to Helical Gear Box.

The first bevel stage makes it feasible to transmit the power at a 90-degree angle with very good efficiency (Unlike Worm Gear Box). Thus, these are used when there is a space limitation for mounting motor in line or where overhang load of motor has to be reduced.

These can be manufactured in variety of configurations such as Right-Angle Bevel with Parallel Shaft Helical Gear Box, Hollow Output Shaft Mounted (with Keyway or Shrink Disc & Torque Arm), Right Angle Bevel with in line Helical Gear Box etc.

These type of right-angle gear boxes are reversible from output to input (Unlike Worm Gear Boxes). Some applications demand reversibility whereas in some applications, reversibility is not desired (such as hoisting etc.). These type of gear boxes are used where the reversibility is desired.

These type of Gear boxes are one of the most commonly used gear boxes for right angle transmission applications. They are commonly used in a wide range of industrial and commercial applications, such as Power Plants, Material Handling, Fertilizer Plant, Sugar Plant, Pharmaceutical Industries, Chemical Industries, Plastic Industries, Textile Industries, etc.

These type of gear boxes are also known as Bevel Helical Gear Reducers.
