A machine builder required a vertical axis drive to draw, stack and transfer parts of pipe in an oil field environment. The application load was very weighty and needed to be transported vertically over an extended distance.
The client also asked to reduce the weight of the structure while keeping a high level of safety.
Because of the high loading, ATLANTA offered a multi-drive answer, which shared the load 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 lengthy racks were used to maximize the number of mounting screws used per section and dowel pins were utilized 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 functioning machine has pairs of foundation plates, each plate having a recess to received a slicing insert. Each pair of base plates is installed on a guide plate, and numerous this kind of instruction plates are installed on a common tubular shaft. Each basis plate includes a gear rack for Woodworking Industry toothed rack. The toothed racks of each pair of foundation plates engage a common pinion set up on the tubular shaft. The radial distance of each foundation plate is modified 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 shifting machines; it transports equipment 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, existence, rigidity, and positioning accuracy.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives are often overlooked as past-generation technology with limited positioning accuracy. However, this assumption is usually invalid.
Precision-ground mounting areas to limited tolerances, wear-resistant surface remedies, individually deburred equipment teeth, and compact, low-mass designs are boosting performance. In fact, rack-and-pinion drives compare favorably to linear motors along with roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic efficiency and unlimited travel distance. Some include premium 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 security and smooth motion.
