Abstract
In a process for the adjustment of backlash between a pinon (20) and a rack (10) in a rack-pinion drive, a motor-gearbox assembly (30) including a motor and a gearbox is supported on a carrier (40) via a positioning mechanism (42) for precisely positioning the assembly (30) in a radial position relative to the rack (10). In the process, the assembly (30) is positioned in a first radial distance relative to the rack (10), using the positioning mechanism (42) and a first circumferential backlash between the pinon (20) and the rack (10) is determined at a first position of the pinion (20) along the rack (10), based on measurements taken on an input side of the gearbox. Then, the assembly (30) and/or the rack (10) are positioned in a second position of the pinion (20) along the rack (10), different from the first position, and a second circumferential backlash between the pinon (20) and the rack (10) is determined at the second position, based on measurements taken on the input side of the gearbox A minimal circumferential backlash is determined from the determined first circumferential backlash and the determined second circumferential backlash (and possibly further measurements), and…
