Spur gears are cylindrical gears with straight teeth cut parallel to their rotational axis, used to connect parallel shafts that rotate in opposite directions. They are known for their simplicity, efficiency, and common usage, with designs that accommodate predominantly rolling contact of the tooth surfaces, achieving high mechanical efficiency of up to 99 percent. Custom spur gears are widely used in industrial equipment to transfer mechanical motion as well as control speed, power and torque. These simple motion gears are cost-effective and durable, providing a positive,constant speed drive to facilitate daily industrial operations.

Spur Gear For Industrial Gearbox
As a type of spur gear, external spur gear are widely used in gearbox applications. Inside each industrial gearbox, spur gears act as the fundamental power transmission element connecting parallel rotating shafts. Featuring straight and parallel teeth, spur gears achieve near 99% mechanical efficiency during meshing, minimizing friction and energy waste during torque and speed adjustment. Their precise tooth also ensures seamless engagement with mating gears, enabling the gearbox to achieve high reduction ratios, compact power output, and improved efficiency. This balanced meshing also reduces stress on individual components and extend the overall life of the industrial gearbox.

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.
