A machine builder required a vertical axis drive to pull, stack and transfer sections of pipe in an oil field environment. The application load was very heavy 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 higher level of safety.
Due to the high loading, ATLANTA offered a multi-drive solution, 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 form, an induction-hardened rack was used. This rack had induction-hardened teeth to provide high thrust capability. To insure that the racks remained stationary under the high loading, two meter long racks were utilized to maximize the amount of mounting screws utilized per section and dowel pins were utilized 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 bottom plates, each plate having a recess to received a slicing put in. Each pair of foundation plates is installed on a guide plate, and numerous this kind of instruction plates are mounted on a common tubular shaft. Each basis plate has a toothed rack. The toothed racks of every pair of base plates engage a common pinion set up on the tubular shaft. The radial distance of each base plate is adjusted by a screw and the racks and pinion be sure that the radial adjustment could be precisely the same for each person in the same pair of base plates.

Linear motion is definitely 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 are often overlooked as past-era technology with limited positioning accuracy. However, this assumption is definitely invalid.
Precision-ground mounting areas to limited tolerances, wear-resistant surface remedies, individually deburred gear teeth, and small, low-mass gear rack for Woodworking Industry styles are boosting performance. In fact, rack-and-pinion drives compare favorably to linear motors in addition to roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic overall performance and unlimited travel range. Some include premium servogears and actuators with backlash significantly less than 1 arc-min., effectiveness to 98.5%, and a lot more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 µm, for protection and smooth motion.
