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 heavy and needed to be transported vertically over an extended 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 solution, which shared the strain over four pinions operating on two lengths of rack. This allowed a smaller rack and gear rack for Woodworking Industry pinion to be used, reducing the weight of the axis drives.
Since accuracy was not essential for the application form, an induction-hardened rack was used. This rack had induction-hardened teeth to supply 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 utilized per section and dowel pins were utilized to pin the racks in place.
The Ever-Power solution met all of the requirements from the client and could handle the high loading from the pipes being transported.
A milling cutter for a wooden functioning machine has pairs of base plates, each plate having a recess to received a slicing put in. Each pair of basis plates is mounted on a guide plate, and numerous this kind of instruction plates are mounted on a common tubular shaft. Each foundation plate includes a toothed rack. The toothed racks of every pair of base 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 can be precisely the same for every person in the same couple of base plates.

Linear motion is certainly indispensable to moving machines; it transports equipment and products effectively and controllably. The mechanisms that generate linear movement are generally ranked by their axial velocity and acceleration, axial forces versus structural volume, 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 can be invalid.
Precision-ground mounting surfaces to limited tolerances, wear-resistant surface remedies, individually deburred gear teeth, and compact, low-mass designs are boosting performance. Actually, 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 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 protection and smooth motion.
