Spur gears are one of the most widely used gear types in mechanical power transmission systems. They feature straight teeth that are parallel to the gear axis, allowing it to transmit motion and power between parallel shafts efficiently. Engineered for mechanical transmissions, this OEM external tooth spur gear for reducer features outstanding material of 20CrMnTi. Featuring a case-hardened surface reaching 58-62 HRC, this gear provides outstanding fatigue resistance and exceptional durability during operation. To guarantee smooth, quiet, and reliable power transmission, each gear is undergoing precision machining by advanced hobbing equipment to strictly meet DIN 8 accuracy class standards, ensuring minimal backlash and superior meshing efficiency.
External Tooth Spur Gear For Reducer
Spur Gear for Reducer
Spur gears are one of the most common cylindrical gears applied in mechanical transmission parts. Their simple structure, high load-bearing capacity, and stable transmission efficiency make them an ideal choice for reducer applications. Our spur gears are specifically engineered for speed reducer units, manufactured from 20CrMnTi steel. Through a precise carburizing and quenching heat treatment, it achieves a surface hardness of 58–62 HRC, delivering excellent wear resistance, and outstanding core toughness to withstand heavy shock loads and continuous operation. Additionally, featuring straight and parallel teeth, spur gears achieve near 99% mechanical efficiency during meshing, minimizing friction and energy waste during torque and speed adjustment.
