Planetary servo gear units
|
|
|
The low backlash PSC planetary servo gear units
are designed for the 30 to 305 Nm torque classes.
They were designed to combine the greatest
possible flexibility and cost-efficiency because
not every application requires high-performance
components.
They provide a basis for diverse, dynamic and
cost-optimized drive solutions.
The PSC planetary servo gear units are available
in the following versions:
- PSC = B5 output, smooth output shaft
- PSKC = B5 output, with keyway
- PSCZ = B14, output, smooth output shaft
- PSKCZ = B14 output, with keyway

The low backlash PSF planetary servo gear units
are designed for the 25 to 3000 Nm torque classes.
The permitted acceleration torques are
significantly higher than these values.
Three output versions are available:
- PSF: Solid shaft
- PSKF: Solid shaft with key
- PSBF: Flange block shaft in accordance with
EN ISO 9409

Helical-bevel servo gear units
|
|
|
The low backlash BSF helical-bevel servo gear
units are designed for the 40 to 1500 Nm torque
classes. The permitted acceleration torques are
significantly higher than these values.
These right-angle servo gear units are available
in five output versions:
- BSF: Solid shaft
- BSKF: Solid shaft with key
- BSBF: Flange block shaft (EN ISO 9409)
- BSHF: Hollow shaft with shrink disc
- BSAF: Hollow shaft with keyway (Shaft
mounted gear unit)
All versions are equipped with a B5 mounting
flange and optional foot mounting and torque arm.
Because of this, these drive units can be
optimally integrated into existing applications.
The combination of a helical input stage and a
hypoid output stage results in ratio ranges which
can be covered by the single-stage bevel (wheel)
and hypoid gear unit or by the single-stage
helical-worm gear unit with high transmission
quality. The circumferential backlash remains
constantly low throughout the gear unit’s
service life.

Accessories and options for servo gear units and servo
gearmotors
Motor adapter
The EPH motor adaptor for planetary servo gear units and EBH
motor adaptor for helical-bevel gear units can be used to
connect all commercial servomotors in a simple and
time-efficient manner to servo gear units from SEW-EURODRIVE.
Reduced backlash
Optional for planetary servo gear units and helical-bevel
servo gear units. The circumferential backlash of these gear
units is considerably less than that of the standard versions
so that positioning tasks can be solved with great
precision. The circumferential backlash is specified in
angular minutes [ '] in the technical data.
Minimized circumferential backlash
Optional for planetary servo gear units. The circumferential
backlash of these gear units is reduced even further than
that of the reduced backlash version and therefore allows
for even greater precision when performing positioning
tasks.
PSC series planetary gear units
Thanks to its high degree of flexibility and variability,
the PSC gear unit series offers economic solutions for many
applications. Combined with drive electronics from SEW-EURODRIVE,
they provide customized, cost-optimized drive solutions that
ensure a high level of process reliability in system
operation. The variability in the tried and tested modular
system allows for simple integration into existing
automation systems.
PSC series overview
- 4 sizes
- Choice of 2 output flanges (B5 or B14)
- Torque range of 30 to 350 Nm (270 to 3100 in-lb)
- Very high power density thanks to direct motor
mounting
- Large variety of reduction ratios
- Flexible motor mounting thanks to new adapter concept
- Reliability thanks to application-specific
lubrication: Oil / grease
- Operation independent of mounting position
- Exterior surface protection OS1 to OS4 optional
May be used wherever varied or reduced machine performance
requires adjustable drive engineering. Cost-effectiveness is
the key criterion.
