A machine builder required a vertical axis drive to draw, stack and transfer sections 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.
Because of 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 sized rack and pinion to be utilized, reducing the weight of the axis drives.
Since accuracy had not been essential for the application form, an induction-hardened rack was used. This rack got induction-hardened teeth to supply high thrust capacity. To insure that the racks remained stationary beneath 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 of the requirements from the client and was able to handle the high loading from the pipes being transported.
A milling cutter for a wooden working machine has pairs of bottom plates, each plate having a recess to received a slicing insert. Each pair of basis plates is installed on helpful information plate, and numerous this kind of instruction plates are installed on a common tubular shaft. Each foundation plate includes a toothed rack. The toothed racks of each pair of bottom plates engage a common pinion set up on the tubular shaft. The radial range of each basis plate is altered 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. USE – Milling cutters for woodworking planetary gearbox machines.
Linear motion is usually indispensable to moving machines; it transports tools 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 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 surfaces to limited tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and compact, low-mass designs are boosting performance. Actually, rack-and-pinion drives compare favorably to linear motors along with roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic overall performance and unlimited travel distance. Some include high quality servogears and actuators with backlash significantly less than 1 arc-min., efficiency to 98.5%, and far more compact sizes than regular servomotor-gear combinations. Some preassembled gear-pinion units may also run true to 10 µm, for security and gear rack for Material Handling Industry smooth motion.
