New planetary gearboxes with mounted pinionEngineering360 News Desk | June 18, 2021
Neugart is extending its portfolio of planetary gearboxes, especially for rack and pinion drives, with an additional option for a mounted pinion from its in-house production.
Two specific types of pinion are available: the PK1 pinion is mounted to the splined output shaft of the gearbox, whereby the secure connection that is required is provided by internal teeth in accordance with DIN 5480. The PM1 pinion, on the other hand, is designed for gearboxes with a flange output shaft, and is equipped with a mechanical interface, which is standardized in accordance with EN ISO 9409-1. Both types are available with a helical cut, and the PK1 is also available with a straight cut. The pinions are also available in four different modules and with different numbers of teeth.
The pinion option can also be combined with a total of eight gearbox series: including a coaxial planetary gearbox with an output shaft (PLHE) and an output flange (PFHE) from the Economy Line, which includes durable and powerful standard gearboxes with an outstanding price/performance ratio. Two coaxial planetary gearboxes with an output shaft (PSN and PLN) or output flange (PSFN and PLFN) and right angle planetary gearboxes (WPLN and WPSFN) are available in the Precision Line, which represents the outstanding accuracy of precision gearboxes.
These pinion/planetary gearbox type combination options ensure that not only can a solution be found for a wide range of applications, but usually several, meaning that the torsional stiffness of the flanged gearboxes is greater than that of gearboxes with an output shaft. If the construction space situation is the decisive criterion, the constructor can use the short gearbox with the output flange or the right angle precision gearboxes. If precision is the decisive factor, the constructor can opt for the greater accuracy and torsional stiffness of the precision gearboxes. On the other hand, economy gearboxes are a solution that is financially more attractive for standard applications.
