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 heavy and would have to be transported vertically over an extended distance.
The customer also asked to minimize the weight of the structure while keeping a higher level of safety.
Because of the high loading, ATLANTA offered a multi-drive alternative, which shared the strain 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 had not been important for the application, an induction-hardened rack was used. This rack acquired 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 amount of mounting screws utilized per section and dowel pins had been utilized to pin the racks set up.
The Ever-Power solution met all of the requirements from the customer and could handle the high loading from the pipes being transported.
A milling cutter for a wooden operating machine has pairs of base plates, each plate having a recess to received a slicing place. Each pair of base plates is mounted on helpful information plate, and numerous such instruction plates are installed on a common gear rack for Woodworking Industry tubular shaft. Each base plate has a toothed rack. The toothed racks of every pair of base plates engage a common pinion set up on the tubular shaft. The radial distance of each foundation plate is altered by a screw and the racks and pinion make sure that the radial adjustment could be specifically the same for each person in the same couple of base plates.

Linear motion can be indispensable to shifting machines; it transports equipment and products efficiently and controllably. The mechanisms that generate linear movement are generally ranked by their axial velocity and acceleration, axial forces versus structural quantity, life, 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 precision. However, this assumption is invalid.
Precision-ground mounting areas to limited tolerances, wear-resistant surface remedies, individually deburred equipment teeth, and small, low-mass designs are boosting performance. Actually, rack-and-pinion drives compare favorably to linear motors as well as roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic functionality and unlimited travel distance. Some include superior servogears and actuators with backlash less than 1 arc-min., performance to 98.5%, and far more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 µm, for protection and smooth motion.
