序言本文研究的主要目标,是动力传动上用的小齿轮齿数为2～4齿制造的大齿数比的圆柱齿轮副,这种齿轮副可供实际应用,但应明确其设计、制造及承载能力。一般说来,动力传递用的圆柱齿轮传动装置的齿数比z_2/z_1,单级的最大限度约为10。为了使齿数比增大,采用减少小齿轮齿数的方法是最有效的。但是,作为传递动力的齿轮,通常z_1=6～7是极 Preamble The main objective of this study is the cylindrical gear pair with a large number of teeth made from 2 to 4 teeth on a power transmission. This gear pair can be used in practice, but its design, manufacture and carrying capacity should be clearly defined . In general, the power transmission with cylindrical gear transmission gear ratio z_2 / z_1, single-stage maximum of about 10. In order to increase the gear ratio, the method of reducing the number of pinion gears is most effective. However, as a power transmitting gear, usually z_1 = 6 to 7 is the pole
