A machine builder required a vertical axis drive to pull, stack and transfer parts of pipe in an oil field environment. The application load was very heavy and would have 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.
Due to the high loading, ATLANTA offered a multi-drive solution, which shared the load over four pinions running 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 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 number of mounting screws utilized per section and dowel pins had been utilized to pin the racks in place.
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 functioning machine has pairs of foundation plates, each plate having a recess to received a slicing put in. Each pair of base plates is mounted on a guide plate, and numerous such instruction plates are mounted on a common tubular shaft. Each basis plate includes a toothed rack. The toothed racks of each pair of foundation plates engage a common pinion installed on the tubular shaft. The radial distance of each basis plate is adjusted by a screw and the racks and pinion make sure that the radial adjustment can be gear rack for Material Handling Industry exactly the same for each person in the same pair of base plates. Make use of – Milling cutters for woodworking planetary gearbox devices.
Linear motion is usually 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, lifestyle, 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 accuracy. However, this assumption is definitely invalid.
Precision-ground mounting areas to limited tolerances, wear-resistant surface remedies, individually deburred gear teeth, and small, low-mass styles are boosting performance. Actually, rack-and-pinion drives evaluate 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 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.
