ISO 9409-1-A Flanged Pinions


We have recently expanded our range of ISO 9409-1-A flanged pinions.  This allows the machine designer the flexibility of choosing the best flanged pinion to meet the application needs.

The new TR flanged pinions have compact designs to reduce the amount of drive torque required.  Traditionally, flanged pinions have large pitch diameters which increase the amount of torque on the reducer they mount to.

With the new TR Pinion range, the pinion pitch diameters are significantly smaller, reducing the drive torque required and allowing a smaller reducer to be used.  The pinions are easily mounted and replaceable if future repair is needed.

This hardened & ground pinion range has a quality level of DIN 5 and is available in straight (spur) and helical-toothed versions, in metric modules 2.0 through 8.0.  The pinions can mount to any reducers with ISO 9409-1 flanged connections, see table below.

The combination of the TR pinions, with their low inertia and high accuracy, used with ATLANTA’s precision gear racks, make it possible to achieve very highly dynamic axis drives with high precision and repeatability.

Other Products Available:

Servo Reducers are available in five levels of precision to meet any application needs.  Perfect for use in applications that demand high performance, precise positioning and repeatability.  Angular backlash levels down to less than 1 arc-minutes are available as standard.  Optional integral pinion shafts are also available to mount directly to hollow output shaft.

Zero-Backlash Rack & Pinion Drives, for applications requiring ultra-precise positioning and repeatability, the system backlash can be eliminated by using a split-pinion or dual pinions.

 

Helical Splined Pinions, are provided with DIN 5480 internal splines to mount directly to popular planetary gearboxes, such as Alpha and Stober.  This interface provides a tight integration of the pinion to the gearbox output, reducing overhung loading and backlash between the components.

Integrated Racks mount directly to most standard linear guides (HIWIN, IKO, INA, NSK, SKF, Star, THK, etc.), eliminating the need for additional machining and alignment, saving time and money.
