Properties of electrically preloaded rack-and-pinion drives
Production Engineering, 2015Ball screw drives are very common in industrial applications and, therefore, thorough analyses of their characteristics exist. Rack-and-pinion drives are a good alternative, if large travel ranges and high dynamics are required. However, they are not scientifically and systematically analysed.

Adaptive preloading for rack-and-pinion drive systems
CIRP Annals - Manufacturing Technology, 2018Abstract In the field of machine tools, rack-and-pinion drive systems are one of the commonly used feed drive systems. In order to achieve the high accuracy specifications of modern production facilities, these drives are electrically preloaded to reduce backlash in the drive train.

Automated backlash determination on rack-and-pinion drives
2023 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2023 12021207One characteristic of rack-and-pinion drives is that they are usually subject to backlash. In non-high precision applications, such as laser cutting, a certain amount of backlash is tolerated.

A rack-and-pinion device at the molecular scale
Nature Materials, 2006Molecular machines, and in particular molecular motors with synthetic molecular structures and fuelled by external light, voltage or chemical conversions, have recently been reported. Most of these experiments are carried out in solution with a large ensemble of molecules and without access to one molecule at a time, a key point for future use of ...
