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

The curved rack will be a special design simply by the customer based on the device requirements and the design envelope they have to work with.
ATLANTA was able to work with the customer on the look of the curved rack to boost it’s manufacturability and confirm that it would be able to handle the application loading. The rack was created as a special item and utilized ATLANTA’s vast experience and knowledge in equipment production.

A precision planetary reducer was selected with a ISO flanged pinion mounted to the output to operate a vehicle on the rack. The flanged pinion provided a compact style to reduce the amount of torque required at the reducer output. The reducer offered a rigid support of the flanged pinion and allowed for a large reduction ratio to get the motor speed up as high as feasible.
What is a gear rack? A rack and pinion is usually a pair of gears which convert rotational movement into linear motion. A circular equipment known as the pinion engages teeth on a linear equipment bar called the gear rack. Rotational motion put on the pinion causes the gear 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 are a few of the machines using gear racks. Gear racks are also found in robotics, CNC routers, materials managing systems, automation systems, and the aerospace market.

We also offer custom gear rack production. We can manufacture gear racks in various materials such as plastic, brass, metal and aluminum. We are able to also manufacture spur gears, bevel gears, helical gears, gear clusters, metric gears, anti-backlash gears, worm gears, gear blanks, gear stock, pinion shafts, ratchets and pawls. We are able to also produce gears with pin hubs, clamp hubs, or hubless.
We manufacture a multitude of equipment types complete or can cut gear teeth upon customer supplied blanks. We make rack and pinion gears, face gears, ring gears and other particular gears for the next industries: aviation, defense and aerospace instrumentation, commercial, energy, general market and equipment, healthcare, leisure, musical instrument, power tool, scientific study and transportation. Ever-Power manufactures gears using contemporary machining solutions to customer specifications.
