A machine builder required a vertical axis drive to pull, stack and transfer parts of pipe in an oil field environment. The application form load was very weighty and would have to be transported vertically over an extended distance.
The customer also asked to reduce the weight of the structure while keeping a higher level of safety.
Due to 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 used, reducing the weight of the axis drives.
Since accuracy had not been important for the application form, an induction-hardened rack was used. This rack acquired induction-hardened teeth to provide high thrust capability. To insure that the racks remained stationary under the high loading, two meter lengthy racks were used to maximize the amount of mounting screws used per section and dowel pins were used to pin the racks set up.
The Ever-Power solution met all of 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 bottom plates, each plate gear rack for Woodworking Industry having a recess to received a slicing put in. Each pair of basis plates is installed on helpful information plate, and numerous such instruction plates are mounted on a common tubular shaft. Each basis plate includes a toothed rack. The toothed racks of each pair of bottom plates engage a common pinion set up on the tubular shaft. The radial distance of each basis plate is modified by a screw and the racks and pinion make sure that the radial adjustment could be specifically the same for every person in the same couple of base plates.

Linear motion is indispensable to shifting machines; it transports equipment and products efficiently and controllably. The mechanisms that generate linear motion are generally rated by their axial velocity and acceleration, axial forces versus 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 can be invalid.
Precision-ground mounting areas to tight tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and small, low-mass styles 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 offer 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.
