Planetary gearboxes (PLG) have the highest continuous torque capacity of all types of gearbox; at the same time they have a very compact design, low weight and excellent efficiency.For our planetary gearboxes there are, depending on customer requirements, a variety of different materials combineable, whereby continuous torques reach up to 160 Nm, and ratios
from 4:1 to 710.5:1 are available.
The construction sizes are partly available to different degrees:
EB: Smooth running l cost-optimized l duty cycle S5
LN: Smooth running l cost-optimized l duty cycle S5
LL: Durable l smooth running l all duty cycles l IP65 optional
HP: High power density l extra robust l all duty cycles l IP65
Spirotec gearboxes (STG) are gearboxes with right-angled output. Core element of the series STG is the spiral wheelset. It enables to reliably transmit high moment with comparatively small centre distance in a small space. The Spirotec Gearbox is outstanding quiet in operation. It is by far less noisy then e.g. bevel gearboxes. The gear is wear-free, because both gearing parts are made of hardened steel. Thus the gearing parts have
an extremely high lifetime and the lubricant is free from contamination, which preserves the sealing rings of drive shaft and output shaft. The gearbox is designed in monobloc construction which provides particularly high meshing precision and a better drive system stiffness.
Worm gearboxes (SG) are noted for their very quietrunning.
The worm gear shaft has bearings on both sides. The gear
components, made of bronze or steel, and the lubrication ensure
a long service life at the rated torque. In many applications,
the right angle (outputshaft 90° to motor) is the optimum design
solution. On request, worm gearboxes can be supplied with a
hollow output shaft.
