基于水田分层土壤的平板挤压力与下陷深度之间的关系,详细分析了作用于轮齿上的正应力随运动状态及结构参数变化的分布特性及正压力的形成过程,得到了正压力和剪切力的解析式。结果表明,滑转率的增加将导致作用于轮齿顶部最大正压力的减小和最大正压力位置角的前移、轮齿驱动面上正压力的增大及正压力位置角的前移。速度临界角对作用于轮齿上的正压力有很大影响。
Based on the relationship between plate extrusion pressure and depth of subsidence in paddy soil, the distribution of normal stress acting on gear teeth with the movement and structural parameters and the forming process of positive pressure are analyzed in detail. Positive pressure And analytical solution of shear force. The results show that the increase of slip rate will lead to the decrease of the maximum positive pressure on the top of the gear tooth and the advancement of the position of the maximum positive pressure, the increase of the positive pressure on the driving face of the gear tooth, and the advancement of the positive pressure position angle. The critical angle of speed has a great effect on the positive pressure acting on the gear teeth.
