A machine builder required a vertical axis drive to pull, stack and transfer sections of pipe in an essential oil field environment. The application form load was very large and needed to be transported vertically over a long 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 option, which shared the load over four pinions running on two lengths of rack. This allowed a smaller sized rack and pinion to be utilized, reducing the weight of the axis drives.
Since accuracy was not important for the application, an induction-hardened rack was used. This rack acquired 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 number of mounting screws used per section and dowel pins had been utilized to pin the racks set up.
The gear rack for Woodworking Industry 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 operating machine has pairs of bottom plates, each plate having a recess to received a slicing place. Each pair of foundation plates is mounted on helpful information plate, and numerous such instruction plates are installed on a common tubular shaft. Each basis plate has a toothed rack. The toothed racks of each pair of bottom plates engage a common pinion set up on the tubular shaft. The radial range of each basis 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 can be indispensable to shifting machines; it transports equipment and products effectively and controllably. The mechanisms that generate linear motion are generally rated by their axial velocity and acceleration, axial forces versus structural quantity, life, 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 usually invalid.
Precision-ground mounting areas to restricted tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and small, low-mass styles are boosting performance. Actually, rack-and-pinion drives evaluate favorably to linear motors in addition to 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 significantly less than 1 arc-min., performance to 98.5%, and far more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 µm, for safety and smooth motion.
