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 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.
Due to 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 utilized, reducing the weight of the axis drives.
Since accuracy was not important for the application, an induction-hardened rack was used. This rack got induction-hardened teeth to provide high thrust capacity. To insure that the racks remained stationary under the high loading, two meter lengthy racks were utilized to maximize the amount of mounting screws used per section and dowel pins had been utilized to pin the racks set up.
The Ever-Power solution met all of 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 place. Each pair of base plates is installed on helpful information plate, and numerous this kind of instruction plates are mounted on a gear rack for Woodworking Industry common tubular shaft. Each basis plate has a toothed rack. The toothed racks of every pair of bottom plates engage a common pinion set up on the tubular shaft. The radial distance of each base plate is altered by a screw and the racks and pinion make sure that the radial adjustment can be specifically the same for every person in the same pair of base plates. USE – Milling cutters for woodworking planetary gearbox machines.
Linear motion is indispensable to moving machines; it transports equipment 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, life, 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 accuracy. However, this assumption is certainly invalid.
Precision-ground mounting surfaces to tight tolerances, wear-resistant surface treatments, individually deburred gear teeth, and compact, low-mass designs are boosting performance. Actually, rack-and-pinion drives compare favorably to linear motors along with roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic functionality and unlimited travel distance. Some include premium servogears and actuators with backlash less than 1 arc-min., efficiency to 98.5%, and a lot more compact sizes than standard servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 µm, for protection and smooth motion.
