A machine builder required a vertical axis drive to pull, stack and transfer sections of pipe in an oil field environment. The application form 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.
Due to the high loading, ATLANTA offered a multi-drive alternative, which shared the strain over four pinions running 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 important 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 lengthy racks were used to maximize the number of mounting screws used per section and dowel pins were used to pin the racks in place.
The Ever-Power solution met all the requirements from the customer 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 place. Each pair of basis plates is installed on helpful information plate, and numerous such instruction plates are installed on a common tubular shaft. Each foundation plate has a toothed rack. The toothed racks of every pair of base plates engage a common pinion installed on the tubular shaft. The radial range of each foundation plate is adjusted by a screw and the racks and pinion make sure that the radial adjustment can be precisely the same for each person in the same pair of base plates.

Linear motion is usually indispensable to moving machines; it transports tools 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, 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 surfaces to limited tolerances, wear-resistant surface remedies, individually deburred gear teeth, and small, low-mass designs are boosting performance. Actually, rack-and-pinion drives evaluate favorably to linear motors and also roller or gear rack for Woodworking Industry ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic performance and unlimited travel distance. Some include high quality 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 security and smooth motion.
