YCB arc gear pumps are mainly gear, KCG axis, the pump body, cover, the axial bearing, sealing etc. Using double circular-arc gear tooth sine curve.
主要有齿轮、轴、泵体、泵盖、轴承套、轴端密封等组成。齿轮采用双圆弧正弦曲线齿形制造。
The shaft is fixed to the wheel body and arranged uniformly on the tooth path, and the outside diameter of the bearing or the shaft sleeve jacketed on the shaft is as wide as the tooth path.
所述轴固联于轮体，等分排列于齿道上，套于轴的轴承或轴套的外径与齿道等 宽。
The calculation results showed the bearing capability of gear transmission could be greatly improved by reasonably selecting tooth profile shift coefficient.
计算结果表明：合理选择变位参数可以大大提高齿轮传动的承载能力。
