A machine builder required a vertical axis drive to pull, stack and transfer parts of pipe in an oil field environment. The application form load was very weighty 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 solution, which shared the strain over four pinions working 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 got induction-hardened teeth to supply high thrust capability. To insure that the racks remained stationary beneath the high loading, two meter lengthy racks were used to maximize the amount of mounting screws utilized per section and dowel pins were used to pin the racks set up.
The Ever-Power solution met all of the requirements from the client and was able to 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 put in. Each pair of basis plates is mounted 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 every pair of base plates engage a common pinion installed on the tubular shaft. The radial distance of each basis plate is altered by a screw and the racks and pinion be sure that the radial adjustment can be precisely the same for each person in the same couple of base plates.

Linear motion is usually indispensable to moving machines; it transports equipment and products effectively and controllably. The mechanisms that generate linear movement are generally ranked by their axial velocity and acceleration, axial forces versus structural volume, 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 definitely invalid.
Precision-ground mounting areas to restricted tolerances, wear-resistant surface remedies, individually deburred gear teeth, and compact, low-mass designs are boosting performance. Actually, rack-and-pinion drives evaluate favorably to linear motors as well as roller or ground-thread ballscrews.
gear rack for Woodworking Industry New-generation rack-and-pinion systems provide high dynamic performance and unlimited travel range. Some include premium 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 can even run true to 10 µm, for protection and smooth motion.
