摘要/Abstract

摘要： 三角转子发动机径向密封片在密封槽内沿径向伸缩的现象称为窜动,它加速了径向密封片与气缸之间的磨损,降低了密封性能。在此对径向密封片窜动的影响因素进行详细分析并对窜动量进行了计算。对转子发动机的设计可起参考作用。

Abstract: The telescopic motion of the radial airproof patch in the airproof groove of the triangle rotor engine is named the stir.It accelerates the abrasion between the cylinder and itself and reduces the airproof performance.The analysis of the influence factors to the stir of the radial airproof patch is expounded and the stir quantity is calculated.It offers references to the design of the triangle rotor engine.

Key words: the theoretic profile of the cylinder, the actual profile of the cylinder, the radial airproof patch, the stir quantity
