A machine builder required a vertical axis drive to draw, stack and transfer sections of pipe in an oil field environment. The application load was very large and needed to be transported vertically over an extended 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 solution, which shared the strain over four pinions operating 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 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 could handle the high loading from the pipes being transported.
A milling cutter for a wooden operating machine has pairs of foundation plates, each plate having a recess to received a slicing put in. Each pair of basis plates is mounted on helpful information plate, and numerous this kind of instruction plates are mounted on a common tubular shaft. Each foundation plate has a toothed rack. The toothed racks of each pair of foundation plates engage a common pinion installed on the tubular shaft. The radial distance of each foundation plate is altered by a screw and the racks and pinion make sure that the radial adjustment could be exactly the same for each person in the same couple of base plates.

Linear motion is usually indispensable to shifting machines; it transports equipment and products effectively and controllably. The mechanisms that generate linear movement are generally rated by their axial velocity and acceleration, axial forces versus structural quantity, existence, rigidity, and positioning precision.
Two common linear systems are linear motors and ballscrew drives. gear rack for Woodworking Industry rack-and-pinion drives are often overlooked as past-era technology with limited positioning accuracy. However, this assumption can be invalid.
Precision-ground mounting areas to tight tolerances, wear-resistant surface remedies, individually deburred gear teeth, and small, low-mass styles are boosting performance. In fact, rack-and-pinion drives evaluate favorably to linear motors as well as roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic overall performance and unlimited travel distance. Some include superior servogears and actuators with backlash less than 1 arc-min., effectiveness to 98.5%, and far more compact sizes than standard servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 µm, for basic safety and smooth motion.
