PKX-ME Right-Angle Planetary Gearbox with Adapter

Planetary gearbox P with KX bevel gearbox and ME adapter. Ratio range 3:1 – 300:1. Max. torque 21 – 3,300 Nm. Backlash 2.0 – 8.5 arcmin. Efficiency 94 – 96%. Protection class IP65 / IP66. Noise level ≤ 64 dB(A). Cast iron housing. Ideal for small and confined installation spaces. The right-angle gearbox is optionally available with reduced backlash, ZV rack-and-pinion drive, ATEX explosion-proof design, or with a directly mounted EZ / LM servo motor without adapter and coupling.

Features of Stober Motor Adapters

• Quick and easy mounting of any servo motor.

• One-piece, robust clamping coupling with expansion function.

• Lowest mass moments of inertia for maximum operating dynamics.

• Balanced for quiet, vibration-free operation, even at high speeds.

• Wide range of motor shaft diameters and lengths.

• Precise fit thanks to accurate motor centering.

• The motor can be removed in any position.

• Optional double sealing of the adapter for larger gearbox models.

• Optionally available without adapter and coupling for direct mounting of EZ or LM servo motors.

• To reduce backlash, the motor shaft bearing must have an axially backlash-free design.

EasyAdapt (ME/MEL)

• One-piece, robust clamping coupling with expansion function.

FlexiAdapt (MF)

• Robust, laser-welded bellows coupling with expansion function.

• With integrated thermal length compensation, compensates for the linear expansion of the motor shaft.

• Motor shaft isolated from axial forces.

Motor Adapter with Backlash-Free Jaw Coupling (MQ)

• With integrated thermal length compensation, compensates for the linear expansion of the motor shaft.
