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 weighty and would have to be transported vertically over a long distance.
The customer also asked to minimize the weight of the structure while keeping a high level of safety.
Due to the high loading, ATLANTA offered a multi-drive answer, which shared the load over four pinions running on two lengths of rack. This allowed a smaller rack and pinion to be utilized, reducing the weight of the axis drives.
Since accuracy had not been important for the application, an induction-hardened rack was used. This rack experienced induction-hardened teeth to gear rack for Woodworking Industry provide high thrust capacity. To insure that the racks remained stationary beneath the high loading, two meter long racks were utilized to maximize the amount of mounting screws used per section and dowel pins were used to pin the racks set up.
The Ever-Power solution met all of the requirements from the customer and was able to 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 put in. Each pair of foundation 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 base plates engage a common pinion set up on the tubular shaft. The radial range of each basis plate is altered by a screw and the racks and pinion make sure that the radial adjustment can be precisely the same for every person in the same couple of base plates.

Linear motion is definitely indispensable to moving machines; it transports equipment and products efficiently and controllably. The mechanisms that generate linear motion are generally ranked by their axial velocity and acceleration, axial forces versus structural volume, existence, 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 precision. However, this assumption is usually invalid.
Precision-ground mounting surfaces to tight tolerances, wear-resistant surface remedies, individually deburred equipment teeth, and compact, low-mass styles are boosting performance. Actually, rack-and-pinion drives compare favorably to linear motors along with roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic efficiency and unlimited travel range. 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 safety and smooth motion.
