Spirit is an economical, low-backlash planetary gearbox with a rotating flange.

 

 

 

 

 

Moderate radial loads can be accepted thanks to the 2 radial ball bearings supporting the shaft.

The planetary ring gear is monobloc (belongs to the housing), to reinforce stiffness.

The rotating output flange provides a convenient solution for attaching wheels (in low-speed AGV applications for instance).

We recommend this line for applications using application factor Ka<1.3 (refer to the information section for more details about application factors).

 

 

 

 

 

 

 

 

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.

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.
