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 large and would have to be transported vertically over a long distance.
The client also asked to minimize 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 operating on two lengths of rack. This allowed a smaller rack and pinion to be used, reducing the weight of the axis drives.
Since accuracy was not essential for the application, an induction-hardened rack was used. This rack acquired induction-hardened teeth to provide high thrust capability. To insure that the racks remained stationary beneath the high loading, two meter long racks were utilized to maximize the number of mounting screws used per section and dowel pins were used 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 operating machine has pairs of base plates, each plate having a recess to received a slicing put in. Each pair of foundation plates is mounted on helpful information plate, and numerous such instruction plates are installed on a common tubular shaft. Each basis plate includes a toothed rack. The toothed racks of every pair of foundation plates engage a common pinion set up on the tubular shaft. The gear rack for Woodworking Industry radial range of each base plate is altered by a screw and the racks and pinion ensure that the radial adjustment could be exactly the same for every person in the same pair of base plates. USE – Milling cutters for woodworking planetary gearbox devices.
Linear motion is certainly indispensable to moving machines; it transports tools 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, life, rigidity, and positioning precision.
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 usually invalid.
Precision-ground mounting areas to limited tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and compact, low-mass designs are boosting performance. In fact, rack-and-pinion drives compare 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 superior servogears and actuators with backlash 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 security and smooth motion.
