A machine builder required a vertical axis drive to draw, stack and transfer parts of pipe in an oil field environment. The application load was very heavy and needed to be transported vertically over a long distance.
The client 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 solution, which shared the strain 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 experienced induction-hardened teeth to provide high thrust capability. To insure that the racks remained stationary under the high loading, two meter long racks were utilized 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 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 base plates, each plate having a recess to received a slicing put in. Each pair of foundation gear rack for Woodworking Industry plates is installed on helpful information plate, and numerous such instruction plates are installed on a common tubular shaft. Each foundation plate includes a toothed rack. The toothed racks of every pair of foundation plates engage a common pinion installed on the tubular shaft. The radial distance of each foundation plate is modified by a screw and the racks and pinion ensure that the radial adjustment could be exactly the same for each person in the same couple of base plates. Make use of – Milling cutters for woodworking planetary gearbox machines.
Linear motion is indispensable to moving machines; it transports equipment 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 systems are linear motors and ballscrew drives. Rack-and-pinion drives are often overlooked as past-era technology with limited positioning accuracy. However, this assumption is certainly invalid.
Precision-ground mounting areas to restricted tolerances, wear-resistant surface treatments, individually deburred equipment teeth, and small, low-mass designs are boosting performance. Actually, rack-and-pinion drives evaluate favorably to linear motors in addition to 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 far 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.
