INTERNAL CONSTRUCTION

  • X-Treme RA is a right-angle, helical, low-backlash planetary gearbox. The planet carrier is a cage, to provide stiffness and acceleration capacity. It is monobloc with the output shaft.

  • The shaft is strongly supported by tapered-roller bearings, to provide very high axial and radial loads acceptance.

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

  • This construction improves acceleration capacity and acceptance of frequent reversals.

  • We recommend this line for applications using application factor Ka<1.6 (refer to the information section for more details about application factors).

Orthogonal planetary gearbox

  • The right-angle transmission is handled by carburized and quenched, spiral-bevel gears made of premium Japanese steel, to offer long-lasting precision and acceptance of high fluctuations of torque or fast reversals.

  • 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.

X-Treme RA LINE FEATURES

SILENT OPERATION

Like for all Reckon gearheads, the X-Treme RA line follows the Perfect PitchTM concept, including the use of helical toothing to provide a silent and safe operation to your system. Refer to the PerfectPitch conceptTM section for more detailed information.

HIGH ACCELERATION CAPACITY, HIGH ADMISSIBLE LOADS ON SHAFT

The planet carrier is a massive monobloc cage, designed to increase torsional stiffness and allow strong acceleration.

It is strongly supported by 2 tapered roller-bearings. This design is adapted to medium to strong acceleration with very high efforts on the output shaft.

LONG-LASTING PRECISION

High-precision planet gears in Japanese, 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.

MONOBLOC RING GEAR

Ring gear belongs to the housing, to increase stiffness compared to the X-treme range.

SAFETY FOR YOUR MOTOR SHAFT BEARINGS

The X-treme range features a standard, balanced coupling with a press-fitted pinion, to limit radial efforts on your motor shaft.
