Rack gear drive - is a type of mechanical gear, which converts the rotational motion of the driving pinion into the linear motion of the rack (rare - vice versa). Rack gear drive transmits the torque and angular speed with a sufficiently high efficiency (0.94 - 0.99). Due to the low price, easy maintenance and good precision of the movement, rack-and-pinion drive is widely used in mechanical industry, construction, mining and other industries.
The racks are a common drive solution in the linear motion technology. "Zetek" company offers a wide range of racks. Depending on the application of rack pair, racks are available with straight, slanting and herringbone teeth. For works at the small and medium speeds, or if a high accuracy of the movement is required, the slanting teeth are applied.
In details ›››Gear wheel (pinion) - is a detail of the gear drive, which is made as a disk with cut teeth. As in the case of racks, the profile of gear wheels can be straight, slanting and herringbone, depending on the drive destination. Performing the rotational movement, pinion is meshed with another gear wheel or rack, making the transmission of angular speed and torque to the driven shaft (or on the rod in the case of rack gear drive).
