A machine builder required a vertical axis drive to pull, 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 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 option, which shared the load over four pinions operating on two lengths of rack. This allowed a smaller rack and pinion to be used, reducing the weight of the axis drives.
Since accuracy was not essential for the application form, an induction-hardened rack was used. This rack got induction-hardened teeth to supply high thrust capacity. To insure that the racks remained stationary under the high loading, two meter long racks were utilized to maximize the number of mounting screws used 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 could handle the high loading from the pipes being transported.
A milling cutter for a wooden functioning machine has pairs of base plates, each plate having a gear rack for Material Handling Industry recess to received a slicing insert. Each pair of foundation plates is mounted on a guide plate, and numerous such instruction plates are installed on a common tubular shaft. Each base plate has a toothed rack. The toothed racks of every 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 precisely the same for each person in the same pair of base plates.

Linear motion is indispensable to shifting machines; it transports tools 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, lifestyle, rigidity, and positioning precision.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives tend to be overlooked as past-era technology with limited positioning accuracy. However, this assumption is certainly invalid.
Precision-ground mounting areas to tight tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and compact, low-mass designs are boosting performance. In fact, rack-and-pinion drives compare favorably to linear motors and also roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic performance and unlimited travel range. Some include premium servogears and actuators with backlash less than 1 arc-min., performance to 98.5%, and a lot more compact sizes than standard servomotor-gear combinations. Some preassembled gear-pinion units can even run true to 10 µm, for safety and smooth motion.
