旋筛式碾米机力能传输规律的分析

Analysis of Force and Energy Transmitting in a Rice Whitener with Rotating Screen Barrel

基于旋筛式碾米机筛筒的机械传动系统故障,对旋筛式碾米机的力能传输规律进行了分析。结果表明,旋筛式碾米机空载与负载时的力能传输路线完全不一样。旋筛的机械传动系统设计必须以米筛的摩擦转矩为依据,并考虑碾米机闷车时的严重情况,实例分析也验证了这一点。

The rules for force and energy transmission in a rice whitener were analyzed based on mechanical transmission troubles of the rotating screen barrel in it.The results indicated that the force and energy of transmitting way with load is fully different from that without load in the rice whitener.The mechanical transmission system for the rotating screen barrel must be designed on the basis of the friction torque applied to the rice screen and under consideration of overload of the rice whitener.This also is verified by an analysis of design instances.
