The new PH series satisfies market requirements for low-backlash planetary gears with higher torsional stiffness and stability together with a longer operational life for the output shaft bearings.
The new PH series satisfies market requirements for low-backlash planetary gears with higher torsional stiffness and stability together with a longer operational life for the output shaft bearings.
The internal workings of this compact design draw on the proven technology of helical cut gears in existing planetary gearboxes.
The output shaft is designed as a flange according to ISO9409.
As a result it is possible to directly bolt on pinions, gearbelt pulleys, transmission shafts, rotary actuators, or rotary tables.
Expensive shaft hub connections such as shrink discs are no longer necessary.
The gearbox series consists of six sizes with torques from 100 to 6000Nm.
Exact gear ratios can be selected in the range of 5 to 100.
The standard model already has a backlash of 3arc-min, and can be easily reduced to 1arc-min.
These characteristics of the new PH planetary gear series are especially suited to drive solutions demanding the highest standards for smooth running, precision and reliability.
