A machine builder required a vertical axis drive to draw, stack and transfer sections of pipe in an essential oil field environment. The application form load was very weighty and would have to be transported vertically over a long distance.
The customer also asked to minimize the weight of the gear rack for Material Handling Industry structure while keeping a higher level of safety.
Due to the high loading, ATLANTA offered a multi-drive alternative, which shared the load over four pinions working on two lengths of rack. This allowed a smaller sized rack and pinion to be utilized, reducing the weight of the axis drives.
Since accuracy was not essential for the application, an induction-hardened rack was used. This rack experienced induction-hardened teeth to supply high thrust capability. To insure that the racks remained stationary under the high loading, two meter lengthy racks were utilized to maximize the number of mounting screws utilized per section and dowel pins had been used to pin the racks set up.
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 foundation plates, each plate having a recess to received a slicing place. Each pair of basis plates is installed on a guide plate, and numerous such instruction plates are installed on a common tubular shaft. Each base plate has a toothed rack. The toothed racks of every pair of bottom plates engage a common pinion installed on the tubular shaft. The radial range of each basis plate is altered by a screw and the racks and pinion ensure that the radial adjustment can be specifically the same for each person in the same pair of base plates.

Linear motion is definitely indispensable to shifting machines; it transports equipment and products effectively 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 accuracy.
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 can be invalid.
Precision-ground mounting areas to restricted tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and small, low-mass designs are boosting performance. Actually, rack-and-pinion drives compare favorably to linear motors as well as roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic functionality and unlimited travel distance. Some include premium servogears and actuators with backlash 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 safety and smooth motion.
