A machine builder required a vertical axis drive to pull, stack and transfer parts of pipe in an oil field environment. The application load was very weighty and needed 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 option, which shared the load over four pinions running on two lengths of rack. This allowed a smaller rack and pinion to be utilized, reducing the weight of the axis drives.

Since accuracy was not essential for the application form, an induction-hardened rack was used. This rack acquired induction-hardened teeth to provide high thrust capacity. To insure that the racks remained stationary under the high loading, two meter lengthy racks were utilized to maximize the amount of mounting screws utilized per section and dowel pins were used to pin the racks in place.

The Ever-Power solution met all the requirements from the customer 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 insert. Each pair of base plates is installed 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 each pair of foundation plates engage a common pinion set up on the tubular shaft. The radial range of each base plate is adjusted by a screw and the racks and pinion be sure that the radial adjustment could be specifically the same for every person in the same pair of base plates.

Linear motion is definitely indispensable to shifting machines; it transports tools and products effectively and controllably. The mechanisms that generate linear movement are generally ranked by their axial velocity and acceleration, axial forces versus structural volume, existence, rigidity, and positioning precision.
Two common linear دنده دنده ای برای صنعت نجاری systems are linear motors and ballscrew drives. Rack-and-pinion drives tend to be overlooked as past-era technology with limited positioning accuracy. However, this assumption can be invalid.

Precision-ground mounting areas to tight 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 and also roller or ground-thread ballscrews.
New-generation rack-and-pinion systems provide high dynamic efficiency and unlimited travel distance. Some include high quality servogears and actuators with backlash less than 1 arc-min., efficiency 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 protection and smooth motion.
