A machine builder required a vertical axis drive to draw, stack and transfer parts of pipe in an essential oil field environment. The application form load was very weighty and needed to be transported vertically over an extended distance.
The client also asked to reduce the gear rack for Material Handling Industry weight of the structure while keeping a high level of safety.
Due to the high loading, ATLANTA offered a multi-drive alternative, which shared the strain over four pinions working on two lengths of rack. This allowed a smaller rack and pinion to be utilized, reducing the weight of the axis drives.
Since accuracy was not important for the application form, an induction-hardened rack was used. This rack had induction-hardened teeth to provide high thrust capability. To insure that the racks remained stationary under the high loading, two meter lengthy racks were used to maximize the amount of mounting screws utilized per section and dowel pins had been utilized to pin the racks set up.
The Ever-Power solution met all the requirements from the customer 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 insert. Each pair of foundation plates is installed on helpful information plate, and numerous this kind of instruction plates are installed on a common tubular shaft. Each base plate has a toothed rack. The toothed racks of every pair of bottom plates engage a common pinion installed on the tubular shaft. The radial range of each base plate is modified by a screw and the racks and pinion ensure that the radial adjustment could be exactly the same for every person in the same couple of base plates. USE – Milling cutters for woodworking planetary gearbox machines.
Linear motion can be indispensable to moving machines; it transports tools and products effectively and controllably. The mechanisms that generate linear motion are generally rated by their axial velocity and acceleration, axial forces versus structural volume, existence, rigidity, and positioning precision.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives are often overlooked as past-era 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 small, low-mass styles are boosting performance. In fact, rack-and-pinion drives evaluate favorably to linear motors as well as roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic overall performance and unlimited travel range. Some include high quality 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 can even run true to 10 µm, for basic safety and smooth motion.
