A machine builder required a vertical axis drive to pull, stack and transfer sections of pipe in an oil field environment. The gear rack for Woodworking Industry application form load was very large and needed 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.
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 rack and pinion to be utilized, reducing the weight of the axis drives.

Since accuracy was not essential 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 under the high loading, two meter lengthy racks were utilized to maximize the number 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 was able to handle the high loading from the pipes being transported.
A milling cutter for a wooden functioning machine has pairs of bottom plates, each plate having a recess to received a slicing insert. Each pair of base plates is installed on a guide plate, and numerous such 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 base plate is modified by a screw and the racks and pinion be 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 moving machines; it transports equipment and products effectively and controllably. The mechanisms that generate linear motion are generally ranked 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-generation technology with limited positioning accuracy. However, this assumption is definitely invalid.

Precision-ground mounting surfaces to tight tolerances, wear-resistant surface treatments, individually deburred gear teeth, and small, low-mass designs are boosting performance. Actually, rack-and-pinion drives evaluate favorably to linear motors and also roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic efficiency and unlimited travel distance. Some include premium servogears and actuators with backlash less than 1 arc-min., performance to 98.5%, and far 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.
