Cost-effective and compact: gearbox system for service robotics

ReBeL gearbox system

ReBeL®: fully integrated single joints

Construct your automation with a ReBeL® actuator. With your control system ...

Quickly build your own robot kinematics with fully integrated individual joints. Based on the ReBeL® gearboxes, an individual robot can be constructed with the help of connecting elements, and thanks to the additional electronic components also as a cobot.
The ReBeL® gearbox can be used, for example, in the last axis of articulated arm, linear robot and delta robots in front of various gripper systems. The cobot gearbox system with fully integrated gearboxes helps implement a wide variety of cobot concepts quickly. The plug & play solution means that the user doesn't have to worry about power electronics.

  • Can be integrated up to 5 times faster than gearboxes without a control system
  • Up to 8 times more torque than RL-S-17
  • 2 installation sizes
  • 25% lighter than standard strain wave gears

The ReBeL strain wave gear is fundamentally different from the previous robolink® worm gears: instead of stepper motors, it uses light, brushless direct current motors (BLDC motors). Add the motor controller, and you have a fully integrated strain wave gear. This type of motor is usually used in service robotics. The gearbox is constructed as follows:

  • A: output with encoder and mounting flange
  • B: tribologically optimised polymer strain wave gear
  • C: brushless DC motor (external rotor)
  • D: CAN-BUS motor driver board
