Frequently Asked Questions
-
Q What materials are available for the double helical gears, and how do I choose the right one?We offer engineering plastics including POM (Crystal Steel) and PA66. POM is recommended for applications requiring high rigidity and dimensional stability, while PA66 is preferred where higher impact resistance and temperature tolerance are needed. Our engineering team can assist you in selecting the optimal material based on your load and environment requirements.
-
Q What is the customization range for the helix angle and modulus?The helix angle can be customized from 0° to 35°, and the modulus range is 0.1 to 2.5. Outer diameters span from 10mm to 100mm with tooth counts from 3 to 100, providing extensive flexibility to meet diverse transmission design requirements.
-
Q What is the minimum order quantity (MOQ) for custom double helical gears?MOQ varies depending on the complexity of the customization and the material selected. Please contact our sales team with your specifications and we will provide a tailored quote along with the applicable MOQ for your project.
-
Q How is tooth profile accuracy ensured during production?All gears are manufactured using full Japanese equipment throughout the production process. Tooth profile accuracy is controlled within ±0.2mm, and each batch undergoes rigorous quality inspection to ensure consistency and precision before shipment.
-
Q Are these gears suitable for high-temperature or extreme-environment applications?Yes. The gears are rated for operating temperatures ranging from -30℃ to 120℃, making them suitable for a wide range of industrial and consumer environments. Noise levels are maintained below 45dB, and the gears pass life tests exceeding 500,000 revolutions without abnormal wear.
