摘要齿轮是重要的机械零件，在消费机械和工业机械中应用广泛。齿轮可分为五种，即正齿轮、斜齿轮、齿条齿轮、蜗杆和伞齿轮。直齿圆柱齿轮是齿轮的基本类型之一，其结构简单，加工方便，因此本文选择直齿圆柱齿轮作为研究对象。采用S形和C形过渡曲线设计直齿圆柱齿轮的轮齿。这些曲线使用G2参数Said-Ball三次曲线和回旋曲线模板构建。结果表明，C型齿轮模型的固有频率为0.7408 Hz，平均值较低，标准差分别为1.00E-3 mm和8.072E-3 mm，与S型齿轮模型和现有的齿轮模型相比，C型齿轮模型的位移最小。
ABSTRACT Gears are crucial mechanical components and considerably used in consumer and industrial machinery. Gears can be grouped into five types namely spur, helical, rack and pinion, worm and bevel. Spur gear has been selected as a case model in this study mainly because it is one of the basic types of gear which can be easily constructed and fabricated. Spur gear tooth is designed using S and C-shaped transition curves. These curves are constructed using the G2 parametric Said-Ball cubic curve and clothoid templates. The result demonstrates that the C-shaped gear model which consists of the natural frequency of0.7408 Hz and low onaverage and standard deviation of 1.00E-3 mm and 8.072E-3 mm offers the most affordable displacement when compared with S-shaped and existing gear models.
