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

 

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)

 

 

 

 

 

 

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.

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 the nominal torque is applicable 20 000 hours.

5. Peak speed only.

6. Applied on the front face of the output shaft at 100rpm.

7. Measured at full load and at 25°C

8. Lifetime at nominal torque and speed. Consult us to obtain a free estimation of lifetime in your working conditions

9. Room temperature. Refer to temperature factors in dedicated section.

10. Ratio 10 at nominal speed, measured at 1m.

11. Actual values can change with design modification

12. Ultimate with rollers is an option (TR), except for size 200, 255 and 285 for which tapered roller bearings are included standard.
