A machine builder required a vertical axis drive to draw, stack and transfer parts of pipe in an essential oil field environment. The application load was very weighty and would have to be transported vertically over a long distance.
The client also asked to reduce the gear rack for Woodworking Industry weight of the structure while keeping a high level of safety.
Because of the high loading, ATLANTA offered a multi-drive option, which shared the load 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 experienced induction-hardened teeth to supply high thrust capability. To 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 had been used to pin the racks set up.
The Ever-Power solution met all the requirements from the client and was able to handle the high loading from the pipes being transported.
A milling cutter for a wooden working machine has pairs of base plates, each plate having a recess to received a slicing place. Each pair of base plates is mounted on a guide plate, and numerous this kind of instruction plates are installed on a common tubular shaft. Each foundation plate includes a toothed rack. The toothed racks of each pair of base plates engage a common pinion set up on the tubular shaft. The radial range of each foundation plate is altered by a screw and the racks and pinion make sure that the radial adjustment could be specifically the same for every person in the same couple of base plates. USE – Milling cutters for woodworking planetary gearbox machines.
Linear motion is definitely indispensable to moving machines; it transports equipment and products efficiently and controllably. The mechanisms that generate linear movement are generally rated by their axial velocity and acceleration, axial forces versus structural volume, lifestyle, rigidity, and positioning accuracy.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives are often overlooked as past-era technology with limited positioning accuracy. However, this assumption can be invalid.
Precision-ground mounting areas to limited tolerances, wear-resistant surface remedies, individually deburred gear teeth, and small, low-mass designs are boosting performance. In fact, rack-and-pinion drives evaluate favorably to linear motors along with roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic functionality and unlimited travel range. Some include high quality servogears and actuators with backlash significantly less than 1 arc-min., performance to 98.5%, and a lot more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units can even run true to 10 µm, for security and smooth motion.
