INTERNAL CONSTRUCTION

Helical planetary gearbox

 

 

 

Wiser is a 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.

 

 

 

 

 

 

Coaxial gearbox

 

 

 

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.

 

 

 

 

 

 

 

PRODUCT-LINE FEATURES

Perfect Pitch concept

QUIET OPERATION

The Wiser range follows the Perfect PitchTM concept, including the use of helical gears to provide a silent and safe operation to your system. Refer to the PerfectPitch conceptTM section for more detailed information.

Low-cost helical gearbox

LOW TO MODERATE ACCELERATION CAPACITY

The planet carrier is a single-block "cage" that was designed to increase torsional stiffness in comparison with a cantilever-type planet carrier. The planets are firmly held from both sides in order to maximize their life in high torque conditions. This planet carrier is strongly supported by 2 radial ball-bearings, to ensure perfect alignment of the planet gears, even at maximum torque. This design is adapted to stable torque or moderate acceleration.

High precision planetary gearbox

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

low-backlash planetary gearbox

MORE SAFETY FOR YOUR MOTOR SHAFT

The Wiser range features a standard, balanced coupling, to make sure vibrations are not transmitted to your motor bearings.

  1. Calculation based on the ISO 6336-2 standard (life = 20,000 h, speed = nominal speed, internal temp = 60°C , Application Factor = 1,25).
  2. Calculation based on the ISO 6336-2 standard (life = 2,000 h, speed = nominal speed, internal temp = 60°C , Safety Factor = 1,4). This rating will not provide a 2,000 hours life if used at max speed. Contact us to get an estimation of the product lifetime in your application. Using a torque higher than the rated torque may affect the gearbox precision.
