A machine builder required a vertical axis drive to pull, stack and transfer sections of pipe in an oil field environment. The application load was very weighty 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 remedy, which shared the strain over four pinions working on two lengths of rack. This allowed a smaller rack and pinion to be used, reducing the weight of the axis drives.
Since accuracy had not been important for the application form, an induction-hardened rack was used. This rack got induction-hardened teeth to supply high thrust capacity. To insure that the racks remained stationary beneath the high loading, two meter lengthy racks were used to maximize the amount of mounting screws utilized per section and dowel pins had been utilized to pin the racks in place.
The Ever-Power solution met all of the requirements from the customer and could handle the high loading from the pipes being transported.
A milling cutter for a wooden operating machine has pairs of base plates, each plate having a recess to received a slicing place. Each pair of base plates is installed on helpful information plate, and numerous such instruction plates are mounted on a common tubular shaft. Each basis plate has a toothed rack. The toothed racks of each pair of bottom plates engage a common pinion installed on the tubular shaft. The radial distance of each base 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 certainly indispensable to shifting machines; it transports tools and products efficiently 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-era technology with limited positioning accuracy. However, this assumption is invalid.
Precision-ground mounting surfaces to restricted tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and compact, low-mass designs 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 provide high dynamic functionality and unlimited travel range. Some include superior servogears and actuators with backlash significantly 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 may also run true to 10 µm, for security and smooth motion.
