A machine builder required a vertical axis drive to draw, stack and transfer parts 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 reduce the weight of the structure while keeping a high level of safety.
Due to the high loading, ATLANTA offered a multi-drive solution, which shared the load over four pinions running 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 acquired induction-hardened teeth to supply high thrust capacity. To insure that the racks remained stationary beneath the high loading, two meter lengthy racks were utilized to maximize the number of mounting screws utilized 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 bottom plates, each plate having a recess to received a slicing insert. Each pair of foundation plates is mounted on a guide plate, and numerous such instruction plates are mounted 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 range of each basis plate is adjusted by a screw and the racks and pinion ensure that the radial adjustment can be exactly the same for each person in the same couple of base plates.

Linear motion is certainly indispensable to gear rack for Material Handling Industry moving machines; it transports equipment and products efficiently and controllably. The mechanisms that generate linear movement are generally rated by their axial velocity and acceleration, axial forces versus structural quantity, existence, 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 surfaces to tight tolerances, wear-resistant surface remedies, individually deburred equipment teeth, and small, low-mass designs are boosting performance. Actually, rack-and-pinion drives evaluate favorably to linear motors along with roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic performance and unlimited travel distance. Some include superior servogears and actuators with backlash significantly less than 1 arc-min., performance to 98.5%, and far more compact sizes than standard servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 µm, for basic safety and smooth motion.
