A machine builder required a vertical axis drive to pull, stack and transfer sections of pipe in an essential oil field environment. The application load was very weighty and needed to be transported vertically over an extended distance.
The client also asked to reduce the weight of the structure while keeping a high level of safety.
Because of the high loading, ATLANTA offered a multi-drive remedy, which shared the strain over four pinions operating 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 essential for the application form, an induction-hardened rack was used. This rack acquired 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 amount of mounting screws used per section and dowel pins were utilized 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 working machine has pairs of base plates, each plate having a recess to received a slicing place. Each pair of base plates is mounted on a guide 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 adjusted by a screw and the racks and pinion gear rack for Woodworking Industry ensure that the radial adjustment can be exactly the same for every person in the same couple of base plates.

Linear motion is indispensable to moving machines; it transports equipment 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, 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 accuracy. However, this assumption is usually invalid.
Precision-ground mounting surfaces to limited tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and small, 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 distance. Some include high quality servogears and actuators with backlash significantly less than 1 arc-min., performance to 98.5%, and a lot more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 µm, for security and smooth motion.
