Case Study for High-Precision Planetary Gear Manufacturing in the Aerospace Field by LS Manufacturing
In hi-tech industries, such as in aerospace, each component has a direct relation to the reliability and safety of all the equipment. We once faced an extremely challenging precision gear case: An aerospace equipment manufacturer was urgently in need of high-precision planetary gears for the new aero-engine whose performance requirements were very stringent.
Customer Challenges
The working conditions require this planetary gear to be stable in extremely low and high temperatures, at high speeds, and under heavy loads; the transmission accuracy must reach the highest ISO 4 standard. Traditional manufacturing processes for gears had bottlenecks in batch consistency and control of heat treatment deformation, failing to meet aerospace certification reliability requirements.
LS Manufacturing Solution
To address this challenge, a systematic solution was worked out by our engineering team. First, specialized software was used to optimize the tooth profile for impact resistance. Second, a German-imported CNC gear hobbing machine was employed for high-consistency rough machining, and controlled atmosphere heat treatment was carried out to precisely control tooth surface hardness and core toughness. Finally, we used CNC gear hobbing for final shaping and utilized a coordinate measuring machine to conduct full-dimensional inspection for each batch of products, so as to achieve traceability of data.
Results and Value
The gears delivered finally met and partially exceeded the accuracy requirements of ISO 4. Under extreme conditions, the service life of these gears improved threefold in the customer's bench tests, thus helping their engine products go through stringent aerospace certification. This solved not only the customer's current problem but also laid a good foundation for long-term strategic cooperation between the two parties.
