（2）画剪力图，弯矩图：（3）＞所以此梁不安全。6．已知一标准渐开线直齿圆柱齿轮，其齿顶圆直径da1＝77.5mm，齿数z1＝29。现要求设计一个大齿轮与其相啮合，传动的安装中心距a＝145mm，试计算这个大齿轮的主要尺寸。（分度圆直径d2、齿顶圆直径da2、齿根圆直径df2、基圆直径db2）解：讲评：牢记和熟练掌握齿轮参数计算公式7．两级平行轴斜齿圆柱齿轮传动如图所示，高速级mn＝3mm，1＝15°Z2＝51；低速级mn＝5mm，Z3＝17试问：（1）低速级斜齿轮旋向如何选择才能使中间轴上两齿轮轴向力的方向相反?（2）低速级齿轮取多大螺旋角2才能使中间轴的轴向力相互抵消?解：（1）低速级斜齿轮旋向为左旋，才能使中间轴上两齿轮轴向力相反。（2）→8.27°8．单级闭式直齿圆柱齿轮传动，已知小齿轮材料为45钢，调质处理，大齿轮材料为ZG45，正火处理，已知传递功率Pl＝4kW，n1＝720r/min，m＝4mm，zl＝25，z2＝73，b1=84mm，b2=78mm，双向运转，齿轮在轴上对称布置，中等冲击，电动机驱动。试校核此齿轮传动的强度。解：小齿选用45号钢，轮调质处理，查表硬度220HBS大齿轮ZG45硬度180HBC查表得查表得：计算转矩：由于原动机为电动机，中等冲击，对称布置，故得K=1.2由于是闭式齿轮，我们先较核齿面接触疲劳强度，我们按标准中心距进行较核：∴（安全）下面，我们再较核齿根弯曲疲劳强度。查表得：＜＜(安全)3．图示的各蜗杆传动均以蜗杆为主动件。试标出图中未注明的蜗轮或蜗杆的转向及旋向，并画出蜗杆和蜗轮受力的作用点和三个分力的方向。（a）（b）答：（a）（b）1．图示所示轮系，已知Z1=18、Z2=20、Z2'=25、Z3=25、Z3'=2、Z4=40，求该轮系的传动比，并判断蜗轮4的转向。解：i＝转向：逆时针2．在图示轮系中，已知z1、z2、z2'、z3、z4、z4'、z5、z5'、z6。求传动比i16。解：3．如图所示的轮系，已知（右旋）若，求齿条线速度的大小和方向。解：4．图示行星轮系，已知Z1=Z2’=41，Z2=Z3=39，试计算传动比iH1解：由于轮3为固定轮（即），＝3．V带传动n1=1450r/min，fv=0.51，包角＝150°，预紧力F0=360N。试问：1）该传动所能传递的最大有效拉力是多少?2）若d1=100mm，其传递的最大转矩为多少?3）若传动的效率为0.95，弹性滑动忽略不计，从动轮输出功率为多少?解：（1）（2）（3）2．请判断图示四个轴中，哪一个轴的结构有错误，出现的是什么错误，应如何改正。
