A machine builder has an app to rotate tooling around an Aerospace element and want to use a curved rack and pinion drive to do this. To keep accurate positioning, there would be two axis drives to rotate the axis and remove backlash using electric preloading.

The curved rack would be a special design by the customer based on the machine requirements and the design envelope they need to work with.
ATLANTA could work with the customer on the look of the curved rack to boost it’s manufacturability and concur that it would be able to handle the application loading. The rack was produced as a special item and used ATLANTA’s vast encounter and knowledge in gear rack for Aerospace Industry equipment production.

A precision planetary reducer was selected with a ISO flanged pinion mounted to the output to drive on the rack. The flanged pinion provided a compact design to reduce the amount of torque required at the reducer result. The reducer offered a rigid support of the flanged pinion and allowed for a large reduction ratio to find the motor increase as high as possible.
What is a equipment rack? A rack and pinion is a couple of gears which convert rotational movement into linear movement. A circular equipment called the pinion engages tooth on a linear gear bar called the apparatus rack. Rotational motion applied to the pinion causes the apparatus rack to move, therefore translating the rotational motion of the pinion into the linear motion of the apparatus rack.

Automotive steering, milling machines, grinders, and meat processing machines certainly are a several machines using gear racks. Gear racks are also found in robotics, CNC routers, materials handling systems, automation systems, and the aerospace market.

We also offer customized gear rack manufacturing. We can manufacture equipment racks in a variety of materials such as for example plastic, brass, metal and aluminum. We can also manufacture spur gears, bevel gears, helical gears, equipment clusters, metric gears, anti-backlash gears, worm gears, gear blanks, gear share, pinion shafts, ratchets and pawls. We are able to also manufacture gears with pin hubs, clamp hubs, or hubless.
We manufacture a wide variety of equipment types complete or can cut gear teeth on client supplied blanks. We make rack and pinion gears, face gears, band gears and other special gears for the next industries: aviation, defense and aerospace instrumentation, commercial, energy, general market and equipment, healthcare, leisure, musical instrument, power tool, scientific research and transportation. Ever-Power manufactures gears using modern machining methods to customer specifications.
