A machine builder required a vertical axis drive to draw, stack and transfer sections of pipe in an oil field environment. The application form load was very large and would have 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.
Because of the high loading, ATLANTA offered a multi-drive remedy, which gear rack for Material Handling Industry shared the strain over four pinions working 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 essential 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 lengthy racks were utilized to maximize the amount 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 was able to handle the high loading from the pipes being transported.
A milling cutter for a wooden working machine has pairs of foundation plates, each plate having a recess to received a slicing put in. Each pair of foundation plates is mounted on helpful information plate, and numerous this kind of instruction plates are installed on a common tubular shaft. Each basis plate includes a toothed rack. The toothed racks of every pair of base plates engage a common pinion set up on the tubular shaft. The radial distance of each basis plate is altered by a screw and the racks and pinion ensure that the radial adjustment could be specifically the same for each person in the same pair of base plates.

Linear motion is indispensable to shifting machines; it transports equipment and products efficiently and controllably. The mechanisms that generate linear movement are generally ranked by their axial velocity and acceleration, axial forces versus structural quantity, life, rigidity, and positioning accuracy.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives tend to be overlooked as past-generation technology with limited positioning precision. However, this assumption is definitely invalid.
Precision-ground mounting surfaces to tight tolerances, wear-resistant surface treatments, individually deburred gear teeth, and small, low-mass designs are boosting performance. Actually, rack-and-pinion drives compare favorably to linear motors and also roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic performance and unlimited travel range. Some include premium servogears and actuators with backlash significantly 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.
