Helical-bevel
gear units from SEW-EURODRIVE provide a high degree of efficiency
of over 95% in both torque directions and at all input speeds –
performance designed to last. High-endurance gearing enables high-torque,
wear-free operation long into the future. The remarkably high efficiency
of our helical-bevel gearmotors makes them energy-savers. As they
also have a long maintenance-free service life, they can be used
in every application with AC asynchronous motors and synchronous
servomotors.

Installation
of angular gear units is particularly space-saving. The attenuation
characteristics are a further bonus resulting from the simplicity
of the mechanical design. As a result of longitudinal application
of the force on the input shaft, the torque impulses are dampened.
The noise level for this device is very low, even when a large amount
of force is applied. This means that our helical-worm gearmotors
can be used even for stage elevators.

The
variety of sizes allows almost all requirements to be met. For high
output speeds, the RX57 to RX107 series of single-stage gear units
offers compact, space-saving solutions. And applications where weight
is an issue will benefit from our multi-stage gear units: Thanks
to their die-cast aluminum design, the models R07, R17 and R27 are
three particularly efficient lightweights – ideal as satellite drives
and for use in light machine constructions.

A
standard drive that is not only favored because of its performance,
but also for its structural properties. Typically found in conveyor
and materials processing applications, the parallel shaft helical
gearmotors from SEW-EURODRIVE can always be relied on to perform
diverse drive tasks.

SPIROPLAN^® servo gearmotors with
directly installed CMP synchronous servomotors are extremely efficient,
quiet and, with a wide variety of different designs, offer the customer
the greatest possible flexibility. The W37/W47 Spiroplan right-angle
gear units enable high speeds at even the smallest reduction ratios
and the wear-free gearing minimizes losses due to friction and optimizes
the mechanical efficiency. Thanks to the gearing, maximum performance
is easily achieved. In addition, the low initial and life cycle
costs make these drives ideal for simple positioning and conveyor
applications.¹
