Gear ratio i=8 for precision gearboxes with helical gearing

Neugart refines the range of coaxial planetary gearboxes and now offers even more choice for the perfect drive solution in the future: Effective immediately, the gear ratio i=8 is also available for precision gearboxes with helical gearing.

The ability to choose between helical and straight gearing for a ratio of i=8 means that the respective design-related advantages for this gear ratio can be used even better for specific applications: Planetary gearboxes with helical gearing are characterized by low-noise and highly precise synchronization. This makes them the right choice for especially demanding applications. In contrast, gearboxes with straight gearing offer a higher power density, especially when it comes to high torques.

Specifically, the new ratio i=8 is available for precision gearboxes with helical gearing having either an output shaft (PSN series) or an output flange (PSFN). The PSN gearbox series has been designed primarily for tasks in which high dynamics and low-noise operation are paramount. The PSFN, on the other hand, with its torsionally stiff flange output shaft, is predestined for highly dynamic applications where positioning accuracy is crucial.

Neugart is one of the few suppliers in the world to offer planetary gearboxes with straight as well as helical gearing. The gear ratio range now extends from i=3 to i=100 for both types of gearing. Single-stage gearboxes are used for gear ratios from i=3 to i=10, while two-stage gearboxes are used in the range between i=12 and i=100. All single-stage coaxial precision gearboxes from Neugart are characterized by a low torsional backlash of less than 3 arcmin. This can even be optionally reduced to less than 1 arcmin. This ensures very high positioning accuracy even with changing directions of rotation.
