FAULHABER focuses on torque, noise, and power with new GPT gearheads

FAULHABER launched its new GPT gearhead household this week. With this new household of drive parts, the corporate stated it has centered on flexibility, energy density, and value.

The brand new collection of gears is designed to work with the DC drives in FAULHABER’s GXR/SXR gearhead household. The gearheads can be flexibly mixed with varied motors from the usual vary, similar to motors from the flat BXT brushless household or brushless DC drives.

This permits for matched mixtures of encoders, drives, and gearheads, stated the Schönaich, Germany-based firm. It added that they are often mixed compactly and with matching diameters with out extra connecting parts.

GPT gears designed for top torques and cargo adjustments

FAULHABER stated it developed the GPT gear collection for notably excessive torques. As much as six planets per stage allow a shorter total size and thus extra energy within the smallest of areas, it defined. The GPT planetary gears are product of hardened stainless-steel, and their connections are repeatedly welded. This allows the dependable transmission of excessive forces.

The gearboxes can be found in diameters from 14 to 42 mm (0.5 to 1.6 in.) and are considerably shorter than various fashions of the identical diameter. They tolerate fixed load adjustments in addition to abrupt or very sturdy ones, in line with FAULHABER.

For instance, the 42 GPT collection can obtain an intermittent torque of as much as 25 Nm. Relying on the variant, steady torques between 06 and 18 Nm and speeds of as much as 24,000 rpm are attainable.

Because of a variety of evenly distributed discount ratios — from 3:1 to 1437:1 — drive methods may be tailored to all kinds of functions, famous FAULHABER. Optimized part coordination and high-performance lubricants contribute to an additional enhance in efficiency, as does the vast choice of completely different output bearings.

FAULHABER reduces noise for collaborative functions

FAULHABER stated it developed the low-noise collection of the GPT household for functions which can be used near folks or as a result of a number of motors are used. With an enter gear stage product of plastic gears, the 22 GPT LN and 32 GPT LN scale back the noise degree by as much as 10 dB in contrast with the usual model, stated the company.

Nonetheless, they’ll transmit occasional peak torques of as much as 4 and 12 Nm, respectively. They function in a large temperature vary from -30° to +110°C (-22° to 230°F) and may keep their excessive effectivity even with frequent or sudden load adjustments. Not solely is their efficiency spectacular, however so is their price-performance ratio, claimed FAULHABER.

The HT fashions are appropriate for environmental situations that require extra strong variants, the corporate stated. With their tailored geometry, they’ll deal with increased masses, supply improved dynamics, and maximize efficiency, it asserted.

The brand new drives can be found with three or 4 gear levels, in quite a few discount ratios, and with an working temperature vary between -30° and +120°C (248°F). Sudden load adjustments or emergency stops don’t restrict the lengthy service lifetime of the drives, stated FAULHABER. The gear backlash is 0.8° or 0.6°, relying on the mannequin, enabling exact and repeatable positioning in a variety of functions.
