摘要
用螺旋容腔平面分布图说明密封腔的形成、分布和移动情况,并导出随马达输出扭矩而产生的转子倾斜力矩的计算公式。说明马达负载压降对容积效率ηv及定子寿命有较大影响。
This article describes the formation, distribution and movement of the spiral chambers of a screw motor by the chambers' plain distribution graph, derives the formula for calculating the rotor's tilt moment accompanying the output torque of the motor, and indicates that the pressure drop of the motor's load exerts considerable influence on the volumetric efficiency and the stator's service life.
