Reduction Gearboxes
In-Line Helical Gearbox

In-line helical bevel reduction gearboxes are used for transmitting mechanical power in-line with the electric motor or input drive.
Used in screw jack systems as the primary drive or on motorised screw jacks. Ideal as the main drive for I configuration jacking systems or H, U and T configurations when connected to an additional bevel gearbox.
Up to 12000Nm torque transmission with gear ratios up to 1481:1.

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
