Reduction Gearboxes
Helical Bevel Gearbox

Helical bevel reduction gearboxes are used for transmitting mechanical power through ninety degrees.
Used in screw jack systems either with a hollow or solid output shaft. Ideal as the main drive for H, U and T configuration jacking systems. Also used fitted directly to screw jacks as a primary drive.
Up to 14000Nm torque transmission with gear ratios up to 1715:1.

Selecting the Right Reduction Gearbox
There are 3 factors to consider when selecting the correct reduction gearbox.
- Select a gearbox type to the closest required power (Pd)
- Find the closest matching output speed hence gear ratio for that gearbox type
- Check that the gearbox power rating is suitable for the actual output speed
