A machine builder required a vertical axis drive to pull, stack and transfer sections 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 minimize the weight of the structure while keeping a higher level of safety.
Due to the high loading, ATLANTA offered a multi-drive option, 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 essential for the application form, an induction-hardened rack was used. This rack had induction-hardened teeth to provide high thrust capability. To insure that the racks remained stationary beneath the high loading, two meter long racks were utilized to maximize the amount of mounting screws utilized per section and dowel pins had been used to pin the racks set up.

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 foundation plates, each plate having a recess to gear rack for Material Handling Industry received a slicing place. Each pair of base 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 base plates engage a common pinion set up on the tubular shaft. The radial distance of each base plate is modified by a screw and the racks and pinion ensure that the radial adjustment could be exactly the same for each person in the same pair of base plates.

Linear motion is usually indispensable to moving machines; it transports tools and products effectively and controllably. The mechanisms that generate linear motion are generally rated by their axial velocity and acceleration, axial forces versus structural volume, lifestyle, rigidity, and positioning accuracy.
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 can be invalid.

Precision-ground mounting surfaces to limited tolerances, wear-resistant surface remedies, individually deburred gear teeth, and small, low-mass styles are boosting performance. In fact, rack-and-pinion drives evaluate favorably to linear motors as well as roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic efficiency and unlimited travel distance. Some include superior servogears and actuators with backlash less than 1 arc-min., efficiency to 98.5%, and a lot more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units can even run true to 10 µm, for protection and smooth motion.
