某型小面额纸币清分机的传动轴强度及齿轮偏置角度校核
|
摘要
小面额纸币清分、计数一体机传动部分主要由锥齿轮、轴等零件组成,锥齿轮、轴的强度是影响清分机运行的主要部件。为了提高清分准确率,延长锥齿轮、轴的使用寿命,计算了锥齿轮和轴的强度,校核了偏置齿轮的角度。实验证明:偏置齿轮偏置角度为30°时,清分准确率高达85%;传动部分的稳定性得以提高,使用寿命得以延长。
A small denomination notes sorting and counting machine transmission parts are mainly composed of bevel gears and shafts. The strength of bevel gears and shafts is the main factor affecting the operation of the separator. In order to improve the accuracy of precision, the service life of bevel gear and shaft is extended, the strength of bevel gears and shafts is calculated, and the bias angle of the offset gears is checked. Experiments show: the bias offset angle of the gear for 30°, and distribution accuracy as high as 85%; the stability of the transmission part is improved, and the service life is extended.
