Planetary gearbox

Dunkermotoren has released the PLG63. A compact planetary gearbox with continuous torque up to 100 Nm, it integrates well with the BG65 S DC servomotor.

The gearbox can also be combined with brushless DC servomotors BG45 and BG75 and with the brushed DC motors GR63 and GR80.

The compact planetary gearbox PLG63 incorporates one, two or three stages of gears, with reductions from 3:1 to 960:1. Low backlash and predominant integer ratios are the basis for the assembly of high-precision drive solutions.

The noiseless running of this planetary gearbox is an advantage for many solutions in industrial automation, such as packaging machinery. This is achieved by using a helical cut gear in the first stage. Long life and maintenance-free operation is possible by nitrated steel gears and steel planetary wheels in the second and third stage. Sealed ball bearings are used on both sides, which are lubricated for their whole life cycle.

The bearings are specified for radial and axial loads up to 800 N at the output shaft. The planetary gearbox is suitable for ambient temperatures from -25 to +90 °C. However, for use in rough environmental conditions, the gearbox is protected against dust, dirt and liquids to IP54 class, and optionally up to IP65.
