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 heavy and needed to be transported vertically over a long distance.
The customer 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 alternative, which shared the strain 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 important for the application form, an induction-hardened rack was used. This rack had 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 amount of mounting screws used per section and dowel pins had been used to pin the racks set up.
The Ever-Power solution met all the requirements from the client and was able to handle the high loading from the pipes being transported.
A milling cutter for a wooden functioning machine has pairs of foundation plates, each plate having a recess to received a slicing put in. Each pair of foundation plates is mounted on helpful information plate, and numerous such instruction plates are installed on a common tubular shaft. Each basis 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 distance of each base plate is adjusted by a screw and the racks and pinion ensure that the radial adjustment can be exactly the same for each person in the same couple of base plates.

Linear motion can be gear rack for Material Handling Industry indispensable to moving machines; it transports equipment and products efficiently and controllably. The mechanisms that generate linear movement are generally rated by their axial velocity and acceleration, axial forces versus structural volume, life, rigidity, and positioning accuracy.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives tend to be overlooked as past-generation technology with limited positioning accuracy. However, this assumption can be invalid.
Precision-ground mounting surfaces to tight tolerances, wear-resistant surface treatments, individually deburred gear teeth, and small, low-mass styles are boosting performance. Actually, rack-and-pinion drives evaluate favorably to linear motors as well as roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic performance and unlimited travel range. 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 basic safety and smooth motion.
