A machine builder required a vertical axis drive to pull, stack and transfer sections of pipe in an oil field environment. The application load was very weighty and would have to be transported vertically over a long distance.
The client also asked to minimize the weight of the structure while keeping a high level of safety.
Because of the high loading, ATLANTA offered a multi-drive solution, 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 had not been essential for the application, an induction-hardened rack was used. This rack got induction-hardened teeth to provide high thrust capability. To insure that the racks remained stationary under the high loading, two meter long racks 
were utilized to maximize the number of mounting screws utilized per section and dowel pins had been utilized 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 base plates is mounted on helpful information plate, and numerous such instruction plates are installed on a gear rack for Material Handling Industry 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 indispensable to moving machines; it transports equipment and products effectively 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 areas to limited tolerances, wear-resistant surface remedies, individually deburred equipment teeth, and small, low-mass styles are boosting performance. In fact, rack-and-pinion drives evaluate favorably to linear motors and also roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic efficiency and unlimited travel distance. Some include superior servogears and actuators with backlash significantly less than 1 arc-min., efficiency to 98.5%, and a lot more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units can even run true to 10 µm, for safety and smooth motion.
