论述了旋耕刀正切刃的设计,推导了正切刃弯折方程,讨论了正切刃滑切角的计算,应用偏心圆方法设计了正切刃,并对有关参数进行了分析。
This paper describes the design of sidelong portion of rotary blades. According to theprocess of manufacture,the sidelong portion of rotary blades are formed by bending the ex-pansion graph on the lengthwise portion plane. The equationof sidelong edge after bendingis derived,and the calculation of grass-removing angles of sidelong portion is discussed in thispaper.It is showed that the grass-removing angles near the bending part are smaller than theother part of the sidelong edge. This is also a reason that rotary blades are easy to be twinedby the grass and straw. With the eccentric circle,the sidelong edge curves are designed, andsome parameters are analysed.
