Industrial robots and collaborative robots (cobots) require drive components that combine the highest positioning accuracy with a compact installation space and low weight. Every axis joint must be low in backlash, stiff and dynamic in order to enable precise path movements and short cycle times. At the same time, low inherent inertia and high overload capacity are decisive for robot performance.
The requirements for service life and reliability are particularly high in robotics, as failures in automated production lines can interrupt entire production processes. Drive components must remain low in backlash and reliable over millions of cycles.
WMH Herion supplies planetary gear unit and pinion systems and servo worm gear units for linear axes and joints in robot systems. The compact drive elements offer high stiffness, low backlash and good dynamic properties for fast and precise robot movements.
For portal and gantry robots, WMH Herion supplies ground rack and pinion drives that combine high feed forces with positioning accurate to the µm. The matched system of rack, pinion and gear unit enables optimum performance and simple system integration.
For robotics, WMH Herion offers ground racks and planetary gear unit and pinion systems for linear axes, servo worm gear units for joint and positioning applications as well as compact couplings for low-backlash drive trains. All products are designed for highly dynamic cycles with the highest repeat accuracy requirements.
WMH Herion supplies complete rack and pinion drive systems for portal and gantry robots as well as drive assemblies for linear axes and positioning systems. The systems are designed for the specific dynamic, accuracy and stiffness requirements of the robot system.
What distinguishes WMH Herion as a partner?
Robot applications and cobots demand drive components with the tightest tolerances, minimal reversal backlash and high fatigue strength in compact dimensions. WMH Herion produces spur gears and gear units in precise quality grades that meet these requirements, and beyond the standard range offers individual special versions for particular installation space specifications and ratio requirements.
What this means for your robotics projects: you receive technical advice from a single source, fast sample deliveries and a stable series supply. Design engineering and sales work together directly, no delays due to long coordination channels. ISO 9001 certified, 100% inspection for safety-relevant elements, proven in robotics and automation technology.
Which rack and pinion drives are suitable for portal robots?
For portal robots, ground helical racks with a planetary gear unit and pinion drive are recommended, as this combination offers the highest positioning accuracy, high stiffness and good dynamic behaviour. WMH Herion supplies all components matched to one another and can cut them to customer length.
What backlash values can be expected with servo worm gear units from WMH Herion?
Servo worm gear units from WMH Herion are designed for low-backlash operation in positioning applications. The exact backlash values depend on the gear unit size and version. WMH Herion will advise you on selecting the optimum gear unit version for your specific accuracy requirements.
Does WMH Herion also supply complete assemblies?
Yes. In addition to individual components, we offer assembled handling axes and complex multi-axis systems, fully assembled, tested and ready for use.
