A machine builder required a vertical axis drive to draw, stack and transfer sections of pipe in an essential oil field environment. The application load was very weighty and needed to be transported vertically over a long 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 alternative, which shared the strain over four pinions operating on two lengths of rack. This allowed a smaller sized rack and pinion to be used, 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 used to maximize the number of mounting screws used 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 could 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 base plates is installed on a guide 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 set up on the tubular shaft. The radial range of each foundation plate is modified by a screw and the racks and pinion ensure that the radial adjustment could be specifically the same for each person in the same pair of base plates.

Linear motion is usually indispensable to shifting machines; it transports equipment and products efficiently and controllably. The mechanisms that generate linear motion are generally ranked by their axial velocity and acceleration, axial forces versus structural volume, life, rigidity, and positioning accuracy.
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 definitely invalid.
gear rack for Material Handling Industry Precision-ground mounting areas to restricted tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and compact, low-mass styles are boosting performance. In fact, rack-and-pinion drives evaluate favorably to linear motors and also roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic efficiency and unlimited travel range. Some include superior 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 basic safety and smooth motion.
