HPG-R Planetary Gear

Precision gears with helical gearing

The HPG-R Series Planetary Gears are available in 5 sizes with sixteen ratios from 3 to 50 with a repeatable peak torque between 5 and 1000 Nm. The torsional resistant output bearing enables the direct attachment of high payloads. Thanks to its helical gearing, the HPG-R is particularly quiet in operation. The preloaded ring gear maintains low backlash over the entire lifetime.

Helical gearing

The helical gearing in combination with the flexible ring gear ensures a long lifetime and low backlash in the gear. Another advantage of helical gearing is its smooth running behaviour in combination with low noise.

Wide range of variants

HPG-R Series planetary gears are available in 3 versions for the output: with output flange, with smooth output shaft and with output shaft and keyway.

Standard servomotors

The motor flange and the integrated clamping element enable the quick attachment of standard servo motors. The gear and motor form a compact and lightweight unit that can withstand high loads.
