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 reduce the weight of the structure while keeping a higher level of safety.
Because of the high loading, ATLANTA offered a multi-drive alternative, which shared the strain 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 was not important for the application form, an induction-hardened rack was used. This rack got induction-hardened teeth to provide high thrust capacity. To insure that the racks remained stationary beneath the high loading, two meter lengthy racks were used to maximize the number of mounting screws used per section and dowel pins had been utilized to pin the racks set up.
The Ever-Power solution met all the requirements from the customer and could handle the high loading from the pipes being transported.
A milling cutter for a wooden functioning 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 foundation 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 every person in the same couple of base plates.

Linear motion is 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, lifestyle, rigidity, and positioning precision.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives are often overlooked as past-generation technology with gear rack for Material Handling Industry limited positioning accuracy. However, this assumption is usually invalid.
Precision-ground mounting surfaces to limited tolerances, wear-resistant surface remedies, individually deburred gear teeth, and small, low-mass designs 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 offer high dynamic overall performance and unlimited travel distance. Some include high quality servogears and actuators with backlash less than 1 arc-min., performance to 98.5%, and far more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 µm, for protection and smooth motion.
