INTERNAL CONSTRUCTION

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.

 

 

 

 

 

spirit LINE FEATURES

MEDIUM ACCELERATION CAPACITY

The planet carrier is supported by 2 radial ball-bearings. This design is adapted to moderate torque variation or acceleration where a particularly low noise level is not required.

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, carburized needles (bearings without cages), in order to maximize torque capacity and lifetime.

The Spirit line features low-backlash (under 5 arc-min backlash for 1-stage gearboxes, and under 8 arc-min backlash for 2 stages gearboxes)

MONOBLOC RING GEAR

The ring gear belongs to the housing, what increases stiffness and allows sharp variations of torque and acceleration. The housing is a monobloc part that includes gear and bearings locations.

SAFETY FOR YOUR MOTOR SHAFT

Spirit features a standard, balanced coupling, to limit vibration on your motor shaft and prolounge your motor's bearings life.

  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.
