A machine builder comes with an program to rotate tooling around an Aerospace component and want to use a curved rack and pinion drive to achieve this. To keep accurate positioning, there will be two axis drives to rotate the axis and remove backlash using electric preloading.
The curved rack will be a special design by the client based on the machine requirements and the look envelope they have 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 loading. The rack was produced as a special item and used ATLANTA’s vast experience and knowledge in gear rack for Aerospace Industry china 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 offered a compact design to reduce the quantity of torque required at the 
reducer result. The reducer offered a rigid support of the flanged pinion and allowed for a huge reduction ratio to obtain the motor increase as high as feasible.
What is a gear rack? A rack and pinion can be a set of gears which convert rotational motion into linear motion. A circular gear known as the pinion engages tooth on a linear equipment bar called the gear rack. Rotational motion applied to the pinion causes the gear rack to move, thereby translating the rotational motion of the pinion into the linear movement of the gear rack.
Automotive steering, milling machines, grinders, and meat processing machines are a several machines using gear racks. Gear racks are also used in robotics, CNC routers, material handling systems, automation systems, and the aerospace sector.
We also offer custom gear rack production. We can manufacture gear racks in various materials such as plastic, brass, steel and aluminum. We can also manufacture spur gears, bevel gears, helical gears, gear 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 multitude of equipment types complete or will certainly cut gear teeth upon client supplied blanks. We make rack and pinion gears, face gears, band gears and other special gears for the following industries: aviation, defense and aerospace instrumentation, commercial, energy, general industry and equipment, healthcare, leisure, musical instrument, power tool, scientific analysis and transportation. Ever-Power manufactures gears using modern machining solutions to customer specifications.
