For high-speed, heavy-load parallel shaft applications, cylindrical helical gears are the industry standard due to their smooth, quiet operation. The angled teeth engage gradually, allowing for higher load capacities and significantly lower operating noise than spur gears. Our high-performance cylindrical helical gear is engineered to deliver smooth, quiet power transmission under demanding operating conditions. Since 2007, our facility in Pujiang has produced high-quality parallel shaft gears. By utilizing advanced CNC gear-hobbing lines and finishing machinery, we supply premium cylindrical helical gear sets that meet the strict requirements of high-speed industrial gearboxes.
We manufacture each cylindrical helical gear from selected alloy steel, utilizing precise hobbing and gear-shaving processes to ensure accurate helix angles and tooth profiles. This precise control over the helix angle ensures optimal tooth contact overlap, reducing vibrations and extending the fatigue life of your drivetrains. Every gear run is tracked through our ISO 9001:2015 certified quality system, with critical dimensions verified on our CY40P gear testing center. For international buyers seeking a reliable, direct-factory gear supplier, we provide competitive pricing, robust packaging, and dedicated technical support to help you grow your business. |
