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 heavy and would have 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.
Because of the high loading, ATLANTA offered a multi-drive solution, which shared the load over four pinions operating on two lengths of rack. This allowed a smaller rack and pinion to be used, reducing the weight of the axis drives.
Since accuracy was not essential for the application form, an gear rack for Material Handling Industry 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 number of mounting screws utilized per section and dowel pins were used to pin the racks in place.
The Ever-Power solution met all the requirements from the client 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 place. Each pair of base plates is mounted on a guide plate, and numerous such instruction plates are mounted on a common tubular shaft. Each foundation plate has a toothed rack. The toothed racks of every pair of bottom plates engage a common pinion installed on the tubular shaft. The radial range of each base plate is altered by a screw and the racks and pinion be sure that the radial adjustment can be exactly the same for each person in the same couple of base plates.

Linear motion is indispensable to shifting 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, lifestyle, rigidity, and positioning precision.
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 definitely invalid.
Precision-ground mounting areas to limited tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and compact, low-mass styles are boosting performance. Actually, 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 performance and unlimited travel distance. Some include high quality servogears and actuators with backlash significantly less than 1 arc-min., efficiency to 98.5%, and a lot more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units can even run true to 10 µm, for protection and smooth motion.
