Custom Gear Production Case Study: Prototype Spur Gear for Drone Drive Unit

Our company has a specialized team skilled in thin-walled processing.

This is an example of a spur gear used in the drive unit of a drone. It was a case where we were commissioned to manufacture gears as a prototype development product. Since the gears are used in drones, they required a small module and a lightweight blank shape. Additionally, due to the active research and development in the industry, there was a request for short lead times for processing at the time of the order. Our company has a specialized team skilled in thin-walled processing, and we carried out the blank processing in that department. Since these are aircraft-related parts, we requested a cooperating company capable of special handling for heat treatment. Furthermore, due to the complexity of the blank shape, process design was challenging, and we took measures to minimize deformation of the blank shape by setting excess material. As a result, we were able to achieve the thin-walled shape requested at the time of the order, and we managed the special processes such as heat treatment without any issues. Additionally, while chamfering is necessary at each corner for stress dispersion, manual chamfering was required for the tooth parts. To suppress variations in quality from such manual work, we continuously conducted shape measurements and quality checks during processing.
