NEUGART GEARBOX FOR SERVO MOTORS

Planetary gearboxes are required for a wide range of electrical motion applications. Together with our manufacturer Neugart we offer various versions of servo gearboxes. Planetary gearboxes with output shaft are most frequently used.

Planetary gearboxes must be securely connected to the servo motor on the motor side (drive input side) and to the customer's mechanical system on the output side. For this purpose, the input flange of the planetary gearhead is individually adapted to the servo motor on the motor side by the manufacturer.

On the output side, various variants are available for the output shaft:

  • output shaft with keyway for positive-fit and reliable power transmission
  • smooth output shaft for a force-fit connection to a clutch (for highest torque transmissions also in reversing operation)
  • Multi-tooth shaft according to DIN 5480 for toothed output shaft (e.g. for force-fit connection to a pinion with internal gearing)

 

The planetary gearbox units with output shaft are the ideal solution for many dynamic applications due to the low inertia of the rotating output shaft. The wide variety of planetary gearheads with output shaft gives you the maximum flexibility to select the right product for your application.

 

The most important features of planetary gearboxes with output shaft:

 

  • flexibility through compact unit consisting of planetary gearbox with output shaft and servo motor
  • flexibility through product variety with 1 to 3 gear stages, various reduction ratios, different toothings
  • low inertia of the rotating output shaft
  • suitable for dynamic applications

 

A special feature of Neugart is the option of purchasing the servo gearboxes directly with an assembled pinion tailored to your application. This means you receive a gearbox-pinion combination developed from a single source that guarantees the ideal technical match for your rack and pinion drive.

 

Another special feature at Neugart is the option of preparing the planetary gearbox directly for use in an industrial truck. The NGV series planetary gearboxes meet the special requirements of AGVs (AGVs) for compact design, high load capacity, high reliability and efficiency. In the NGV servo gearbox, specially developed wheels almost completely encase the gearbox. This means that the gearbox is basically located outside the vehicle in the wheel. This saves space. If the overall length of the drivetrain is to be reduced even further, the gearbox can also be mounted in what is known as direct engine mounting. In this case, the sun pinion is mounted directly on the motor shaft and the gearbox housing is bolted to the motor. This saves even more length by eliminating the motor adapter plate.

 

A wide variety of adapters make it possible to fit the NGV gearbox to almost any motor. Your advantage: You can use the optimum motors and control units for your application, because Neugart, as a pure gearbox manufacturer, offers its solutions independent of motors and control units from batch size 1. As Actronic Solutions, we can also offer you ready-made packages with servo motor and servo controller for low voltage, so that you can put your AGV into operation straight away:

 

 

The stainless steel servo gearboxes of the HLAE series from the manufacturer Neugart have been specially adapted to the requirements of the pharmaceutical industry and food technology. To prevent contamination, not only did the material have to be carefully selected, but the geometry of the gearbox also had to be designed in such a way that no dirt pockets or biofilms of germs and bacteria could form. The hygienic design of the HLAE gearbox has no dead spaces. Corners and edges are specially rounded to prevent build-up. The electropolished stainless steel surface and the special seals for IP69K protection also allow regular cleaning, even with aggressive cleaning substances.

 

The HLAE stainless steel servo gearboxes can be easily combined with our Kollmorgen hygienic servo motors and Tolomatic stainless steel lead screw linear actuators:
