A machine builder required a vertical axis drive to draw, stack and transfer sections of pipe in an 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 minimize the weight of the structure while keeping a higher level of safety.
Due to the high loading, ATLANTA offered a multi-drive alternative, which shared the strain over four pinions running 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 was not essential for the application, an induction-hardened rack was used. This rack acquired induction-hardened teeth to supply high thrust capacity. To insure that the racks remained stationary under the high loading, two meter lengthy racks were used to maximize the number of mounting screws utilized per section and dowel pins were used to pin the racks in place.
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 working machine has pairs of foundation plates, each plate having a recess to received a slicing put in. Each pair of basis plates is installed on a guide plate, and numerous such instruction plates are installed on a common tubular shaft. Each base plate has a toothed rack. The toothed racks of each pair of bottom plates engage a common pinion installed on the tubular shaft. The radial range of each basis plate is modified by a screw and the racks and pinion ensure that the radial adjustment could be specifically the same for every person in the same pair of base plates.

Linear motion is usually indispensable to moving machines; it transports equipment and products effectively and controllably. The mechanisms that gear rack for Woodworking Industry generate linear movement are generally rated by their axial velocity and acceleration, axial forces versus structural volume, life, rigidity, and positioning accuracy.
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 certainly invalid.
Precision-ground mounting areas to restricted tolerances, wear-resistant surface treatments, individually deburred gear teeth, and compact, low-mass designs are boosting performance. In fact, rack-and-pinion drives compare favorably to linear motors in addition to roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic overall performance and unlimited travel distance. Some include high quality servogears and actuators with backlash significantly less than 1 arc-min., effectiveness 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.
