A machine builder required a vertical axis drive to draw, stack and transfer parts of pipe in an essential oil field environment. The application load was very large and needed to be transported vertically over a long distance.
The customer also asked to minimize the weight of the structure while keeping a higher level of safety.
Due to the high loading, ATLANTA offered a multi-drive remedy, which shared the load over four pinions running on two lengths of rack. This allowed a smaller rack and pinion to be used, reducing the weight of the axis drives.
Since accuracy was not essential for the application form, an induction-hardened rack was used. This rack had induction-hardened teeth to supply high thrust capacity. To insure that the racks remained stationary beneath the high loading, two meter lengthy racks were used to maximize the number of mounting screws used per section and dowel pins had been used to pin the racks in place.
The Ever-Power solution met all of the requirements from the customer and was able to handle the high gear rack for Material Handling Industry loading from the pipes being transported.
A milling cutter for a wooden working machine has pairs of base plates, each plate having a recess to received a slicing place. Each pair of base plates is installed on helpful information plate, and numerous such instruction plates are mounted on a common tubular shaft. Each foundation plate includes a toothed rack. The toothed racks of each pair of foundation plates engage a common pinion set up on the tubular shaft. The radial range of each basis plate is altered by a screw and the racks and pinion be sure that the radial adjustment can be specifically the same for every person in the same pair of base plates.

Linear motion is indispensable to shifting machines; it transports tools and products effectively and controllably. The mechanisms that generate linear motion are generally rated by their axial velocity and acceleration, axial forces versus structural volume, existence, rigidity, and positioning precision.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives tend to be overlooked as past-era technology with limited positioning precision. However, this assumption is invalid.
Precision-ground mounting surfaces to restricted tolerances, wear-resistant surface treatments, individually deburred gear teeth, and compact, low-mass designs are boosting performance. In fact, rack-and-pinion drives compare favorably to linear motors in addition to roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic functionality and unlimited travel range. Some include high quality servogears and actuators with backlash less than 1 arc-min., performance to 98.5%, and a lot more compact sizes than standard servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 µm, for basic safety and smooth motion.
