A machine builder required a vertical axis drive to draw, stack and transfer parts of pipe in an oil field environment. The application load was very large and would have to be transported vertically over an extended distance.
The client 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 remedy, which shared the strain over four pinions running 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 essential for the application, 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 utilized to maximize the number of mounting screws utilized 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 gear rack for Woodworking Industry foundation plates, each plate having a recess to received a slicing place. Each pair of basis plates is installed on helpful information plate, and numerous such instruction plates are installed on a common tubular shaft. Each base plate has 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 foundation plate is adjusted by a screw and the racks and pinion make sure that the radial adjustment can be specifically the same for each person in the same couple of base plates. Make use of – Milling cutters for woodworking planetary gearbox devices.
Linear motion can be indispensable to moving machines; it transports tools and products efficiently and controllably. The mechanisms that generate linear motion are generally rated 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 are often overlooked as past-generation technology with limited positioning accuracy. However, this assumption is invalid.
Precision-ground mounting surfaces to restricted tolerances, wear-resistant surface remedies, individually deburred equipment teeth, and small, low-mass styles are boosting performance. In fact, rack-and-pinion drives compare favorably to linear motors along with roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic functionality and unlimited travel distance. Some include high quality servogears and actuators with backlash 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 may also run true to 10 µm, for safety and smooth motion.
