A machine builder required a vertical axis drive to pull, stack and transfer parts of pipe in an essential oil field environment. The application form load was very weighty and would have to be transported vertically over a long distance.

The client also asked to reduce the weight of the structure while keeping a higher level of safety.
Due to the high loading, ATLANTA offered a multi-drive option, which shared the strain over four pinions running on two lengths of rack. This allowed a smaller sized rack and pinion to be utilized, reducing the weight of the axis drives.

Since accuracy had not been essential for the application, an induction-hardened rack was used. This rack got induction-hardened teeth to supply high thrust capacity. To insure that the racks remained stationary beneath the high loading, two meter lengthy racks were utilized to maximize the amount of mounting screws utilized per section and dowel pins had been used to pin the racks set up.

The Ever-Power solution met all of the requirements from the client and was able to handle the high loading from the pipes being transported.
A milling cutter for a wooden operating machine has pairs of foundation plates, each plate having a recess to received a slicing place. Each pair of base plates is mounted on a guide plate, and numerous this kind of instruction plates are installed on a common tubular shaft. Each base plate has a toothed rack. The toothed racks of each pair of foundation plates engage a common pinion set up on the tubular shaft. The radial distance of each basis plate is altered by a screw and the racks and pinion be sure that the radial adjustment could be precisely 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, life, rigidity, and positioning accuracy.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives are often overlooked as past-era 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 along with roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic overall performance and unlimited travel range. Some include superior servogears and actuators with backlash less than 1 arc-min., effectiveness to 98.5%, and far more compact sizes than gear rack for Material Handling Industry standard servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 ┬Ám, for protection and smooth motion.
