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 heavy and needed 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 option, 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, 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 amount of mounting screws utilized per section and dowel pins were utilized to pin the racks in place.
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 working machine has pairs of base plates, each plate having a recess to received a slicing insert. Each pair of foundation plates is installed on helpful information plate, and numerous this kind of instruction plates are installed on a common tubular shaft. Each base plate includes a toothed rack. The toothed racks of every pair of base plates engage a common pinion installed 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 can be specifically the same for every person in the same pair of base plates.

Linear motion is usually indispensable to shifting 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 gear rack for Material Handling Industry structural volume, existence, rigidity, and positioning precision.
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 certainly invalid.
Precision-ground mounting areas to limited tolerances, wear-resistant surface remedies, individually deburred equipment teeth, and compact, low-mass styles are boosting performance. In fact, 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 overall performance and unlimited travel distance. Some include superior servogears and actuators with backlash less than 1 arc-min., effectiveness to 98.5%, and far 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.
