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

The curved rack would be a special design simply by the customer based on the device requirements and the design envelope they need to work with.
ATLANTA was able to work with the customer on the design of the curved rack to improve it’s manufacturability and concur that it would end up being able to handle the application form loading. The rack was created as a particular item and used ATLANTA’s vast encounter and knowledge in 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 style to reduce the amount of torque needed at the reducer result. The reducer provided a rigid support of the flanged pinion and allowed for a huge reduction ratio to get the motor increase as high as possible.
What is a equipment rack? A rack and pinion is a pair of gears which convert rotational motion into linear motion. A circular gear known as the pinion engages teeth on a linear gear bar called the apparatus rack. Rotational motion put on the pinion causes the apparatus rack to move, thereby translating the rotational motion of the pinion into the linear movement 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 handling systems, automation systems, and the aerospace sector.

We also offer customized gear rack production. We can manufacture equipment racks in a variety of materials such as plastic, brass, metal and aluminum. We are able to also produce 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 wide variety of gear types complete or will cut gear teeth on consumer supplied blanks. We make rack and pinion gears, face gears, ring gears and other unique gears for the following industries: aviation, defense and aerospace instrumentation, industrial, energy, general gear rack for Aerospace Industry china sector and equipment, healthcare, leisure, musical instrument, power tool, scientific analysis and transportation. Ever-Power manufactures gears using modern machining methods to customer specifications.
