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 heavy and needed to be transported vertically over a long distance.
The customer 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 remedy, which shared the strain over four pinions working on two lengths of rack. This allowed a smaller sized rack and pinion to be used, reducing the weight of the axis drives.
Since accuracy was not important for the application, an induction-hardened rack was used. This rack got induction-hardened teeth to provide high thrust capability. To insure that the racks remained stationary under the high loading, two meter long racks were used to maximize the amount of mounting screws used per section and dowel pins were 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 insert. Each pair of foundation plates is installed on a guide 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 bottom plates engage a common pinion set up on the tubular shaft. The radial range of each basis plate is modified by a screw and the racks and pinion be sure that the radial adjustment can be precisely the same for every person in the same couple of base plates.

Linear motion can be indispensable to moving machines; it transports equipment and products gear rack for Material Handling Industry efficiently and controllably. The mechanisms that generate linear motion are generally rated by their axial velocity and acceleration, axial forces versus structural quantity, life, 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 accuracy. However, this assumption can be 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 as well as roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic performance and unlimited travel range. Some include high quality servogears and actuators with backlash significantly 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.
