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 weighty and needed to be transported vertically over an extended distance.
The customer 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 answer, which shared the load over four pinions working on two lengths of rack. This allowed a smaller rack and pinion to be utilized, reducing the weight of the axis drives.
Since accuracy had not been important for the application, an induction-hardened rack was used. This rack experienced induction-hardened teeth to supply high thrust capacity. 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 set up.
The Ever-Power solution met all the requirements from the client and was able to handle the high loading from the pipes being transported.
A milling cutter for a wooden functioning machine has pairs of base plates, each plate having a recess to received a slicing put in. Each pair of foundation plates is installed on a guide plate, and numerous such instruction plates are mounted on a common tubular shaft. Each basis plate has a toothed rack. The toothed racks of each pair of base 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.

Linear motion can be indispensable to shifting machines; it transports tools and products effectively and controllably. The mechanisms that generate linear movement are generally rated by their axial velocity and acceleration, axial forces versus structural quantity, existence, rigidity, and positioning precision.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives tend to be overlooked as past-era technology with limited positioning precision. However, this assumption is invalid.
Precision-ground mounting areas to limited tolerances, wear-resistant surface remedies, individually deburred equipment teeth, and small, low-mass designs are boosting performance. Actually, rack-and-pinion drives compare favorably to linear motors and also roller or ground-thread ballscrews.
New-generation rack-and-pinion systems offer high dynamic efficiency and unlimited travel distance. Some include superior servogears and actuators with gear rack for Material Handling Industry backlash significantly 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 can even run true to 10 µm, for security and smooth motion.
