Series

The G series a new generation of TwinSpin® high precision reduction gears with a new design of the main bearing and improved performance for the most demanding applications. G series introduced the increase in torque to weight ratio in comparison to the previous generation. Innovative design of main bearing resulted in the unprecedented tilting stiffness, high precision of the output bearing, and modularity of design which allows for customized solutions. Further improvements introduced with G series has yielded further friction reduction in transmission mechanism, lower hysteresis and low settings of Lost Motion, especially in small sizes. Finally, new sizes of reducers have been introduced with G series in standard and hollowshaft design to broaden the portfolio and application range of TwinSpin® reducers.

Advantages

high tilting stiffness
low friction
high precision output bearing
high torque density
reduced lost motion settings
high torque overload capacity

Series

The GH series represents TwinSpin high precision reduction gears with through-holes in the shafts, also known as the hollow-shaft version. Cables, tubes with compressed air, drive shafts and so on can be led through the hole in the shaft of the gear. The GH series high precision reduction gears comprise an accurate reduction mechanism and high-capacity radial and axial cylindrical bearings. This design of the reduction gears allows the mounting of the load directly on the output flange or case without a need of additional bearings.

Advantages

Large input shaft diameter
Fully sealed
Zero backlash reduction gears
High moment capacity
Excellent positioning accuracy and positioning repeatibility
High torsional and tilting stiffness

Load values in the table are valid for the nominal life of L10 = 6 000 [Hrs]..
· High precision reduction gears are preferred for intermittent cycles (S3-S8); the output speed in applications is an inverted variable.
· The continuous mode cycle (S1) should be consulted with the manufacturer.
· If the output speed in application is below 0,1 rpm please consult with the manufacturer.
· The values in the table refer to nominal operating temperature.
· Please note the temperature on the gear case that should not exceed 60°C.
