摘要以螺旋角30°新型人字齿同步带和螺旋角0°直齿为研究对象，在相同实验条件下，对新型人字齿同步带传动进行噪声和振动实验研究。结果表明：(1)噪声与带横向振动同初张力、带的线密度、转速和产生的轴向力有关。 (2)新型人字齿不同于直齿同步带啮合冲击机理，比直齿同步带噪声低，最大降噪11 dB（A）。(3)新型人字齿比直齿同步带横向振动响应小，高速运行更平稳。(4)同国外螺旋角10°的斜齿和螺旋角20°的双螺旋齿同步带相比，新型人字齿同步带具有更好的降噪性能。

Abstract：The double helical synchronous belt with the spiral angle of 30 °and the straight tooth with 0° were chosen as research object. And the transmission noise and vibration were explored under the same experimental conditions. The experimental results show that: (1) the noise and transverse vibration are related to the initial tension, belt line density, rotational speed and axial force; (2) the noise level was decreased by 11 dB (A) compared with straight tooth synchronous belt due to the difference meshing impact mechanism; (3) the new double helical synchronous belt has smaller transverse vibration response and runs more stable than straight tooth one under high speed; (4) the noise reduction performance is better than the helical tooth with spiral angle of 10°and the double helical tooth with spiral angle of 20°abroad.

Key words： Double helical synchronous belt transmission Straight tooth synchronous belt Noise；Vibration；frequency
