The GPL-V (shaft) and GPL-H (hollow) are the company's lowest backlash (≤ 0.1 arc minute) planetary gearboxes for horizontal and vertical robotic applications. A patented design guarantees that the backlash will not increase over the life time of the gearbox. High tilting rigidity results in excellent positioning accuracy with a rated 20,000 hours, which is reportedly more than three times longer than comparable gearboxes in the market.
The noise level of 65dB compared to 69dB of comparable models makes it ideal for MRI applications where low noise levels are critical.
The efficiency is over 90 percent compared to 70 – 80 percent of other models allowing for lower power consumption, which could result in choosing a smaller motor.
Features include:
- Zero backlash (< 0.1arcmin)
- High torsional rigidity, torque density and accuracy
- Torque range from 400-3,000Nm
- 90 percent efficiency
- 65 dB noise level
- 20,000 hour service life
- Compact design
- Flange and hollow output designs
- Right-angle versions
- Seven frame sizes from 180-330mm
- Subassembly and fully enclosed versions
- Ratios from 40-200
- No maintenance

backlash
Reaction in dynamic motion systems where potential energy that was created while the object was in motion is released when the object stops. Release of this potential energy or inertia causes the device to quickly snap backward relative to the last direction of motion. Backlash can cause a system’s final resting position to be different from what was intended and from where the control system intended to stop the device.
