Straight-cut gearing for a simple and cost-effective solution
- The Access range uses straight toothing, a more economical alternative to helical gearing—though inherently louder and offering reduced smoothness in operation.
- Backlash levels range from 7 to 18 arc-min, suitable for standard applications without stringent positioning requirements.
One-piece forged-steel housing
The monobloc forged-steel housing integrates the internal ring gear, broached directly into the casing. This construction ensures:
-
solid structural strength (no screw, no glue),
-
and cost-optimized manufacturing.
Case-Hardened and Tempered Planet Gears
The planet gears are made from carburized and quenched steel, providing:
-
long-term backlash stability,
-
increased wear resistance,
-
and the ability to withstand frequent accelerations and repetitive load profiles.
Forged-steel cage-type planet carrier
The planet carrier is a forged-steel cage, forming a monobloc assembly with the output shaft, which delivers:
-
unrivaled torsional stiffness for its category,
-
high mechanical reliability,
-
and reduced sensitivity to deformation under standard duty cycles.
Cantilevered output shaft support
The entire output stage operates in an overhung configuration, supported by two ball bearings at the gearbox output. This economical design is ideal for:
-
moderate radial loads,
-
low-dynamic applications,
-
machinery where extreme rigidity is not critical.
Especially suitable for:
-
applications with moderate radial and axial loads,
-
cost-efficient machines or standard duty cycles,
-
systems requiring 8 arc-minutes of backlash without the need for high rigidity,
-
projects where high product competitiveness is essential, without sacrificing reliability.
Fast, Secure and Easy Connection
- The motor-shaft interface uses a precision-balanced coupling, designed to minimize loads on the motor bearings and ensure smooth operation.
- Installation is quick and intuitive thanks to a single-bolt clamping system on the motor shaft, providing a firm and reliable assembly.
- Each gearbox is supplied with a motor-specific adapter flange, ready for immediate installation.
