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

The customer also asked to minimize the weight of the structure while keeping a high level of safety.
Due to the high loading, ATLANTA offered a multi-drive gear rack for Woodworking Industry alternative, which shared the strain over four pinions working on two lengths of rack. This allowed a smaller rack and pinion to be used, 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 under the high loading, two meter lengthy racks were utilized to maximize the amount of mounting screws used per section and dowel pins had been used to pin the racks in place.

The Ever-Power solution met all the requirements from the client and was able to handle the high loading from the pipes being transported.
A milling cutter for a wooden working machine has pairs of foundation plates, each plate having a recess to received a slicing place. Each pair of foundation plates is mounted on helpful information plate, and numerous this kind of instruction plates are installed on a common tubular shaft. Each foundation plate has a toothed rack. The toothed racks of every pair of base plates engage a common pinion installed 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 exactly the same for every person in the same pair of base plates.

Linear motion can be indispensable to moving 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 quantity, existence, 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 is usually invalid.

Precision-ground mounting surfaces to limited tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and compact, low-mass designs are boosting performance. In fact, rack-and-pinion drives evaluate favorably to linear motors and also roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic overall performance and unlimited travel range. Some include premium servogears and actuators with backlash less than 1 arc-min., efficiency to 98.5%, and far more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 ┬Ám, for basic safety and smooth motion.
