A machine builder required a vertical axis drive to draw, stack and transfer parts of pipe in an oil field environment. The application form load was very large and would have to be transported vertically over a long distance.
The customer also asked to minimize the weight of the structure while keeping a high level of safety.
Due to the high loading, ATLANTA offered a multi-drive solution, 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 essential for the application, an induction-hardened rack was used. This rack had induction-hardened teeth to supply high thrust capacity. To insure that the racks remained stationary beneath the high loading, two meter lengthy racks were utilized to maximize the amount of mounting screws used per section and dowel pins were utilized to pin the racks set up.
The Ever-Power solution met all of the requirements from the customer and could handle the high loading from the pipes being transported.
A milling cutter for a wooden operating machine has pairs of foundation plates, each plate having a recess to received a slicing put in. Each pair of basis plates is installed on helpful information plate, and numerous such instruction plates are mounted 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 distance of each basis plate is adjusted by a screw and the racks and pinion ensure that the radial adjustment can be precisely 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 certainly indispensable to shifting 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 quantity, life, 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 precision. However, this assumption is invalid.
Precision-ground mounting areas to restricted tolerances, wear-resistant surface treatments, individually deburred gear teeth, and small, low-mass designs are boosting performance. In fact, rack-and-pinion drives gear rack for Material Handling Industry evaluate favorably to linear motors in addition to roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic overall performance and unlimited travel distance. Some include premium servogears and actuators with backlash significantly less than 1 arc-min., performance to 98.5%, and far more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units can even run true to 10 µm, for protection and smooth motion.
