INTERNAL CONSTRUCTION

Ultimate RA is a heavy-duty, right-angle, low-backlash helical planetary gearbox. 

  • The planet carrier is a massive cage providing stiffness and acceleration capacity.
  • It is monobloc with the output flange.
  • The cage is centered into the inner planetary ring by means of 2 preloaded angular-contact ball bearings (for small sizes) or tapered-roller bearings (sizes above 140). This construction reinforces the acceleration capacity and the gearbox acceptance of fast reversals.
  • We recommend this line for applications using application factor Ka<2.25 (refer to the information section for more details about application factors).

Right-angle gearhead

  • The motor shaft connection is a balanced coupling, so the efforts on your motor bearings are minimal.
  • Installation is fast and easy thanks to a 1-screw lock to your motor shaft.
  • The input flange features weight reduction.
  • The gearbox will be delivered with the adapting flange corresponding to your motor.

FEATURES

QUIET OPERATION

The Ultimate RA line follows the Perfect PitchTM concept, including the use of helical toothing to provide a silent and safe operation to your system. Refer to the PerfectPitch conceptTM section for more detailed information.

VERY HIGH ACCELERATION CAPACITY

The planet carrier is a massive cage, designed to increase torsional stiffness and acceleration capacity. This design provides a perfect alignment of the gears, even at maximum torque. 

This gearbox is adapted to permantent, extreme variations of torque like in delta robots or punching machines.

HIGH RADIAL AND AXIAL LOADS ACCEPTANCE

The planet carrier is strongly by angular-contact ball-bearings or tapered roller bearings (sizes above 140).

MONOBLOC RING GEAR IN FORGED STEEL

The planetary ring gear is monobloc with the output adapting flange and includes the 2 bearing locations.

LONG-LASTING PRECISION, WITH UP TO 4 SATELLITE GEARS PER STAGE

High-precision planet gears in Japanese, carburized and quenched steel allow high torque density and strong accelerations, year after year, without loss of precision.

They are supported by large, carburized needles (bearings without cages), in order to maximize torque capacity and lifetime.

SAFETY FOR YOUR MOTOR SHAFT

The Ultimate RA line features a standard, balanced coupling with a press-fitted pinion, to limit radial efforts on your motor shaft.

  1. Following the ISO 6336-2 standard, for a 20,000 hours life with a 1,25 application factor, at nominal speed with 60°C internal temperature. Applying a lower torque prolounges life significantly.

  2. Following ISO 6336-2 standard, for 2,000h (10% of life) with a 1,4 safety factor, at nominal speed with 60°C internal temperature. Using a torque higher than the nominal torque wears the internal gears.

  3. 1,000 occurences maximum

  4. Speed at which nominal torque can be applied for 20,000 hours

  5. Acceptable for a short duration only

  6. Applied at the middle of the output shaft with a 100 rpm speed.

  7. Measured with a 60°C gearbox using nominal speed and torque. Refer to temperature factors in dedicated section.

  8. Minimum life at nominal speed and torque. Using lower speed and/or torque prolounges life significantly.

  9. At nominal speed, measured at 1m.

* Other ratios are available upon request

** For 2 stages gearboxes, we can have a reduced input (R) or a powerful input (P). The standard is with a reduced input.

!  Sizes 200 and above lead-time can reach 10 to 12 weeks for the 1st order.
