Helical bevel gearbox

Round the corner with the right motor: Helical bevel gearboxes.

Are you looking for higher dynamics, lower weight, a very small installation space for the angular transmission of motion and forces?

Here’s the solution from STOBER: helical bevel gearboxes from the K, KL and KS series!

BENEFITS

When developing its helical bevel gearboxes, STOBER focused on achieving the lowest possible power loss – and reaching a high gear efficiency. The gearboxes achieve the best value of 97% in particular due to the high-quality technology used to manufacture the helical gearing.

Other outstanding features are the unsurpassed smooth operation and the high power density.

The torsion-resistant monoblock design favorably reduces the noise development of the gearboxes.

97% gear efficiency

K gearboxes are very torsion-resistant helical bevel gearboxes featuring high-quality helical gearing. The series is available in three different classes, so you can adapt it perfectly to the application you need.

K gearboxes also have an impressive single-cast design and a wide range of housing designs.

The gearboxes are available either as compact servo, Lean or asynchronous helical bevel geared motors for direct attachment or they can be attached to all common synchronous servo motors by suitable adapters.

KL series helical bevel gearboxes are also manufactured from a single mold without any seams and are used primarily when applications call for high dynamics, low weight and, above all, a small installation space. This makes them ideal for the packaging industry.

KL gearboxes also have an impressive and extremely attractive price-performance ratio.

The gearboxes are either available as directly attached, compact servo or Lean helical bevel geared motors or they can be attached to all common synchronous servo motors by suitable adapters.

Thanks to the technology that provides robust bearings and high-quality gearing, the gearboxes of the KS series are extremely durable and tip-resistant.

They can be used in continuous operation without any problems – even at high speed levels. One of the most important features of the KS series is also its very high torsional stiffness.

KS gearboxes are either available as directly attached, compact servo bevel geared motors or they can be attached to all common synchronous servo motors by suitable adapters.
