【摘要】 分析了小参数涡旋压缩机压缩腔的压力载荷和温度,建立了小参数涡旋齿的弯曲疲劳强度模型。以天然气涡旋压缩机为例,计算了小参数涡旋齿的弯曲疲劳强度。结果表明,选择合适的排气角、材料和参数,修正涡旋齿的起始端,是提高涡旋齿弯曲疲劳强度的重要方法。更多还原

【Abstract】 The pressure loads and temperatures in compression chambers of scroll compressor with small parameters are analyzed.A bending fatigue strength model for scroll wrap is established.The bending fatigue strength of scroll wrap with small parameters is calculated set the natural gas scroll compressor as an example.The result shows that the important method of improving the bending fatigue strength of scroll wrap is to select suitable discharge angle,material and parameter,and to correct the starting side of scroll wrap.更多还原
