A machine builder required a vertical axis drive to draw, stack and transfer parts of pipe in an essential oil field environment. The application form load was very weighty and needed to be transported vertically over a long distance.
The client 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 answer, which shared the strain over four pinions operating 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 had not been 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 beneath the high loading, two meter long racks were used to maximize the number of mounting screws used per section and dowel pins were used to pin the racks in place.
The Ever-Power solution met all 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 place. Each pair of basis plates is mounted on helpful information plate, and numerous such instruction plates are mounted on a common tubular shaft. Each base plate includes a toothed rack. The toothed racks of each pair of foundation plates engage a common pinion set up on the tubular shaft. The radial range of each foundation plate is modified by a screw and the racks and pinion make sure that the radial adjustment can be exactly the same for every person in the same pair of base plates.

Linear motion is 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 quantity, life, rigidity, and positioning accuracy.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives are often overlooked as past-generation technology with limited positioning precision. However, this assumption is certainly invalid.
Precision-ground mounting surfaces to tight tolerances, wear-resistant surface treatments, individually deburred gear teeth, and compact, low-mass designs are boosting performance. Actually, rack-and-pinion drives evaluate favorably to linear motors and also roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic efficiency 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 rack for Woodworking Industry gear-pinion units can even run true to 10 µm, for safety and smooth motion.
