A machine builder required a vertical axis drive to pull, stack and transfer sections of pipe in an oil field environment. The gear rack for Woodworking Industry application form load was very heavy and needed to be transported vertically over an extended distance.
The customer also asked to minimize the weight of the structure while keeping a higher level of safety.
Because of the high loading, ATLANTA offered a multi-drive solution, which shared the load over four pinions operating 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, an induction-hardened rack was used. This rack got induction-hardened teeth to supply high thrust capability. To insure that the racks remained stationary under the high loading, two meter lengthy racks were used 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 of the requirements from the customer and could handle the high loading from the pipes being transported.
A milling cutter for a wooden working machine has pairs of base 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 foundation plates engage a common pinion set up on the tubular shaft. The radial range of each base plate is modified by a screw and the racks and pinion be sure that the radial adjustment can be specifically the same for each person in the same couple of base plates.

Linear motion is definitely 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 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-era technology with limited positioning precision. However, this assumption can be invalid.
Precision-ground mounting areas to limited tolerances, wear-resistant surface remedies, individually deburred gear 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 offer high dynamic overall performance and unlimited travel range. 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.
