A machine builder required a vertical axis drive to draw, stack and transfer sections of pipe in an oil field environment. The application load was very large and would have to be transported vertically over an extended distance.

The client also asked to reduce the weight of the structure while keeping a higher level of safety.
Because of the high loading, ATLANTA offered a multi-drive remedy, which shared the strain over four pinions operating 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 experienced induction-hardened teeth to supply high thrust capacity. To gear rack for Material Handling Industry insure that the racks remained stationary under the high loading, two meter long racks were used to maximize the amount of mounting screws used 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 operating machine has pairs of foundation plates, each plate having a recess to received a slicing place. Each pair of basis plates is installed on a guide plate, and numerous such instruction plates are installed on a common tubular shaft. Each basis plate includes a toothed rack. The toothed racks of each pair of foundation plates engage a common pinion set up on the tubular shaft. The radial range of each foundation plate is modified by a screw and the racks and pinion be sure that the radial adjustment can be exactly the same for each person in the same pair of base plates.

Linear motion is usually indispensable to shifting machines; it transports tools 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, 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-generation technology with limited positioning precision. However, this assumption is invalid.

Precision-ground mounting areas to restricted tolerances, wear-resistant surface treatments, individually deburred gear teeth, and compact, low-mass styles are boosting performance. In fact, rack-and-pinion drives compare 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 high quality servogears and actuators with backlash less than 1 arc-min., efficiency 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.
