INTERNAL CONSTRUCTION

Ultimate is a heavy-duty, low-backlash planetary gearbox. 

 

Low-backlash planetary gearhead

The planet carrier is a massive, rigid cage providing stiffness and acceleration capacity.

It is monobloc with the rotating output flange, for superior stiffness. Using a rotating flange instead of a male shaft improves significantly the radial and axial load acceptance.

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), for maximum load capacity. 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).

Note that we have developed a version of Ultimate especially for delta robots : "Ultimate NB" (consult us for more information)

 

 

 

High precision planetary gearbox

 

 

 

The servomotor 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 servomotor.

 

 

The gearhead will be delivered with the adapting flange corresponding to your motor.

 

 

 

ULTIMATE LINE FEATURES

QUIET OPERATION

The Ultimate 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 the torsional stiffness and the acceleration capacity. This design provides a perfect alignment of the gears, even at maximum torque. 

This gearhead is adapted to permanent, extreme variations of torque like in laser-cutting machines, delta robots or punching machines.

HIGH RADIAL AND AXIAL LOAD CAPACITY

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

Ultimate features a rotating output flange instead of a male shaft.

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

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

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

SAFETY FOR YOUR MOTOR SHAFT

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