As the most prevalent kind of cylindrical gears, spur gears have a simple design characterized by straight teeth evenly distributed along the gear’s perimeter. They are extensively employed in industrial mechanical setups due to their simple structure and stable efficiency in operation. Engineered for electric motors and gearboxes, this OEM module 3 spur gear is manufactured from premium 40Cr alloy steel. With a precise heat treatment achieving 50-55HRC, it ensures superior wear resistance to handle frequent starts and continuous loads. Manufactured with high accuracy standards, the module 3 spur gear also guarantees low noise, stable meshing, and high transmission efficiency under high-speed operation.

Customized Spur Gears for Motor
As an important component for industrial equipment, spur gears are closely related to motor smooth and stable running. Specially engineered for high-speed electric motor applications, our spur gears combine cost-effectiveness with excellent mechanical performance. Manufactured from high-quality 40Cr alloy steel, these module 3 spur gears undergo a strictly controlled heat treatment process to achieve 50-55HRC, effectively reducing friction and improving gear performances during operation. They also minimize transmission vibration and reduce noise during operation, helping motors run smoothly and energy-efficiently under continuous loads, thereby improving overall motor efficiency.

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.
