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 large and needed to be transported vertically over a long distance.
The customer also asked to reduce the weight of the structure while keeping a higher level of safety.
Due to the high loading, ATLANTA offered a multi-drive alternative, which shared the load over four pinions operating on two lengths of rack. This allowed a smaller sized rack and pinion to be utilized, reducing the weight of the axis drives.
Since accuracy was not essential for the application, an induction-hardened rack was used. This rack experienced induction-hardened teeth to supply high thrust capacity. To insure that the racks remained stationary under the high loading, two meter long racks were utilized to maximize the amount of mounting screws used per section and dowel pins had been 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 working machine has pairs of bottom plates, each plate having a recess to received a slicing place. 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 foundation plate includes a toothed rack. The toothed racks of each pair of base plates engage a common pinion installed on the tubular shaft. The radial range of each foundation plate is altered by a screw and the racks and pinion ensure that the radial adjustment can be precisely the same for every person in the same pair of base plates.

Linear motion can be indispensable to shifting machines; it transports tools and products effectively and controllably. The mechanisms that generate linear motion are generally rated by their axial velocity and acceleration, axial forces versus structural volume, life, 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 usually invalid.
Precision-ground mounting areas to restricted tolerances, wear-resistant surface remedies, individually deburred equipment teeth, and compact, low-mass 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 provide high dynamic performance and unlimited travel range. Some include superior 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 gear rack for Material Handling Industry preassembled gear-pinion units may also run true to 10 µm, for protection and smooth motion.
