MKH modular screw jack bevel gearbox

An economical solution for simple positioning tasks was always a customers’ wish that was not easy to fulfill. But now it is possible - with an MKH.
We were able to achieve this by a rigorous design-for-manufacture that incorporated all the cost advantages offered by production technology.

*Single-stage bevel gearing, with transmission ratios 1:1 or 2:1 and trapezoidal spindles, for loads up to 1000 N.

*MKH can be supplied:

• as a basic-version screw jack, where the spindle performs the motion

• as a travelling-nut screw jack, where the spindle rotates, and the nut performs the motion

• as transmission gearing in 4 versions, with 1:1 or 2:1 transmission ratio, maximum permitted speed 1000 rpm.

KH screw jack bevel gearbox

Type KH1 – KH3 screw jack bevel gearboxes are used as an preferred alternative to our worm gear jacks when high rates of motion are required (e.g. > 3meters/min) and the loads are not too high.

Typical applications are in automation and handling machinery, where duty cycles can be as high as 50%.

Ball-screw spindles are used, to ensure high quality performance. The bevel gear set features hardened and ground spiral-toothed bevel gears. The gearboxes are supplied with grease lubrication as standard. For more demanding requirements, we also offer oil lubrication.

The screw jack bevel gearboxes are available in basic and moving-nut versions, both types with transmission ratios of 1: 1 or 2:1.
3: 1 is possible in special cases.

If screw jack bevel gearboxes are compounded or used as jack systems, then no additional right-angle gearing is required, unlike worm gear jacks.

Brake motors are required to drive the KH gearboxes, since they are not self-locking. For manual positioning and subsidiary applications, we recommend our MKH modular screw jack bevel gearboxes.
