A machine builder required a vertical axis drive to pull, stack and transfer parts of pipe in an oil field environment. The application load was very large and needed to be transported vertically over an extended distance.
The client also asked to reduce the weight of the structure while keeping a high level of safety.
Due to the high loading, ATLANTA offered a multi-drive alternative, which shared the load over four pinions operating on two lengths of rack. This allowed a smaller sized rack and pinion to be used, gear rack for Woodworking Industry reducing the weight of the axis drives.
Since accuracy was not essential for the application, an induction-hardened rack was used. This rack experienced induction-hardened teeth to provide 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 were utilized to pin the racks set up.
The Ever-Power solution met all of the requirements from the customer and could handle the high loading from the pipes being transported.
A milling cutter for a wooden operating machine has pairs of base plates, each plate having a recess to received a slicing place. Each pair of base plates is mounted on a guide plate, and numerous such instruction plates are installed on a common tubular shaft. Each basis plate includes a toothed rack. The toothed racks of every pair of foundation plates engage a common pinion set up on the tubular shaft. The radial distance of each foundation plate is adjusted by a screw and the racks and pinion ensure that the radial adjustment can be precisely the same for every person in the same couple of base plates.

Linear motion is usually indispensable to shifting machines; it transports equipment and products effectively and controllably. The mechanisms that generate linear motion are generally ranked by their axial velocity and acceleration, axial forces versus structural volume, lifestyle, rigidity, and positioning precision.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives are often overlooked as past-generation technology with limited positioning accuracy. However, this assumption can be invalid.
Precision-ground mounting areas to tight tolerances, wear-resistant surface remedies, individually deburred gear teeth, and compact, low-mass styles are boosting performance. Actually, rack-and-pinion drives compare favorably to linear motors in addition to roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic performance and unlimited travel distance. Some include superior servogears and actuators with backlash less than 1 arc-min., effectiveness to 98.5%, and a lot more compact sizes than standard servomotor-gear combinations. Some preassembled gear-pinion units can even run true to 10 µm, for security and smooth motion.
