A machine builder required a vertical axis drive to pull, stack and transfer sections of pipe in an essential oil field environment. The application form load was very large 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 high level of safety.
Due to the high loading, ATLANTA offered a multi-drive alternative, which shared the load over four pinions working on two lengths of rack. This allowed a smaller rack and pinion to be utilized, reducing the weight of the axis drives.
Since accuracy was not essential for the application, an induction-hardened rack was used. This rack got induction-hardened teeth to supply high gear rack for Material Handling Industry thrust capacity. To insure that the racks remained stationary beneath the high loading, two meter lengthy racks were used to maximize the amount of mounting screws utilized per section and dowel pins were used 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 insert. Each pair of base plates is installed on a guide plate, and numerous such instruction plates are mounted on a common tubular shaft. Each base plate includes a toothed rack. The toothed racks of each pair of bottom plates engage a common pinion set up on the tubular shaft. The radial range of each base plate is altered by a screw and the racks and pinion make sure that the radial adjustment could be precisely the same for each person in the same couple of base plates.

Linear motion is indispensable to shifting machines; it transports tools and products efficiently and controllably. The mechanisms that generate linear movement are generally rated 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 tend to be overlooked as past-generation technology with limited positioning precision. However, this assumption is certainly invalid.
Precision-ground mounting areas to tight tolerances, wear-resistant surface remedies, individually deburred gear teeth, and small, low-mass designs are boosting performance. Actually, rack-and-pinion drives evaluate 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 high quality servogears and actuators with backlash less than 1 arc-min., effectiveness to 98.5%, and far more compact sizes than standard servomotor-gear combinations. Some preassembled gear-pinion units can even run true to 10 µm, for basic safety and smooth motion.
