Spur gears are the most common type of gears used to transmit power between two parallel shafts. Because the tooth traces are parallel to the shaft axis, axial thrust force can be minimized, enabling highly efficient power transmission. These spur gears used in UAV applications are characterized by excellent 40Cr steel and experience qualified heat treatment process to achieve 50-55 HRC, delivering exceptional impact resistance and outstanding wear durability during high-speed operations. To guarantee high efficiency and smooth operation, each gear is machined by advanced hobbing equipment, strictly meeting the DIN 8 standard. This precision ensures minimal backlash and superior meshing efficiency in flight control systems.

Spur Gear for UAV Applications
Our customized pump spur gears are manufactured from premium 40Cr alloy steel and processed to strict DIN 8 standards with complete heat treatment standards to 50-55HRC, perfectly matched to continuous operation of UAV systems for several advantages. First of all, it delivers excellent impact and wear resistance during continuous air operation, significantly reducing the risk of sudden power loss caused by gear damage. What’s more, it shows minimum backlashes as the DIN8 standard guarantees extremely tight gear meshing with minimal backlash. This translates to direct power transmission immediately. Furthermore, spur gears are easy to repair install and repair with high efficiency, brings much convenience in outdoor UAV activities.

Forging
When gears need high performance that needs to withstand high loads, high stress, impact loads or fatigue loads, forgings are suggested to use. Forging allows metal fibers to be continuously distributed along the gear profile, significantly improving root strength and fatigue life.
Turning
This is the process of cutting and shaping solid materials into precise parts. It uses tools like lathes, mills, and drills to remove excess material. Machining transforms a simple block of metal into a finished, functional component.
Gear Cutting
Gear Cutting includes all processes to create gear teeth after rough or fine machining. It shapes teeth to ensure smooth and efficient power transfer for performance, strength and cost efficiency.
Heat Treatment
Gears need to be running with two gears or above two gears, that makes them easy to be worn-out. That’s why most types of gears need to be harden through heat treatment.
ID & OD & Surface Grinding
ID grinding, OD grinding, Surface grinding are all belonging to CNC grinding which are the foundational precision abrasive machining processes used to achieve exceptional dimensional accuracy and surface finishes, especially on hardened materials.
Tooth Grinding
Tooth Grinding are the final processes are applied after heat treatment to correct distortion, improve geometry, and achieve the final surface finish necessary for quiet, efficient power transmission.
