A machine builder required a vertical axis drive to draw, stack and transfer sections of pipe in an essential oil field environment. The application form load was very heavy and needed to be transported vertically over a long distance.
The customer also asked to minimize the weight of the structure while keeping a higher 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 got induction-hardened teeth to supply high thrust capability. To insure that the racks remained stationary under the high loading, two meter long racks were utilized to maximize the amount of mounting screws utilized per section and dowel pins had been used to pin the racks in place.
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 operating machine has pairs of bottom plates, each plate having a recess to received a slicing put in. Each pair of foundation plates is installed on helpful information plate, and numerous this kind of 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 range of each basis plate is modified by a screw and the racks and pinion make sure that the radial adjustment could be specifically the same for each person in the same pair of base plates.

Linear motion is certainly indispensable to moving machines; it transports tools and products efficiently and controllably. The mechanisms that generate linear motion are generally rated by their axial gear rack for Woodworking Industry velocity and acceleration, axial forces versus structural quantity, existence, rigidity, and positioning accuracy.
Two common linear systems are linear motors and ballscrew drives. Rack-and-pinion drives are often overlooked as past-era technology with limited positioning precision. However, this assumption is usually invalid.
Precision-ground mounting surfaces to limited tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and small, low-mass designs are boosting performance. In fact, 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 overall performance and unlimited travel range. Some include premium 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 basic safety and smooth motion.
