Wiser SQ is an economical, helical planetary gearbox.

 

 

The planet carrier is a "cage" (monobloc part holding the gears from both sides), providing stiffness and acceleration capacity to the gearbox.

 

The planet carrier is monobloc with the output shaft too.

 

This cage is centered into the inner planetary ring by means of 2 radial ball-bearings. This construction reinforces the acceleration capacity because the tilt of the shaft is limited, and the gearbox is able to accept significant torque variations.

 

 

 

 

 

 

 

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 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.
