Description

极少齿斜齿轮齿廓
本发明涉及一种齿轮端截齿廓。
目前研制适用于物质输送、增(减)压、计量使用场合的极少齿斜齿轮副的工作已成为人们很感兴趣的课题，而斜齿轮齿廓的研究是最为根本的内容。日本国昭58-6131专利所公开的齿廓是一种由摆线、渐开线和长幅外摆线所构成的齿廓，该专利的实施也成功地应用于容积式流量计。但是，该齿廓的渐开线与长幅外摆线的交点为奇点，运行过程中，相当一段时间内奇点都处于啮合状态。
本发明为克服上述现有技术存在的缺点而提供一种由圆的包络线、圆弧与长幅外摆线构成的极少齿斜齿轮端截齿廓。
本发明通过以下技术措施实施，它由圆的包络线a-b、圆弧b-c、长幅外摆线c-d构成光滑曲线，d-f为齿根圆弧，e-a为齿顶圆弧，b点在分度圆上。其中圆弧b-c与长幅外摆线c-d相切(无奇点)。几何尺寸相同，旋向相反，具有上述齿廓的一对斜齿轮，其工作齿面为共轭曲面。本发明斜齿轮副端截齿廓各段曲线的啮合关系如图2所示。1和1’分别是斜齿轮O和斜齿轮O’的节圆，在运行过程中，节圆1和1’作相对纯滚动，同时圆弧b-c与圆的包络线a’-b’共轭啮合，a沿着长幅外摆线c’-d’移动，并且圆弧b’-c’与圆的包络线a-b共轭啮合，a’沿长幅外摆线c-d移动。
本发明具有以下优点：(一)无奇点，啮合性能好，(二)便于加工，(三)特别适合于制造大口径的装置，且结构紧凑，(四)容易实现动平衡，因此运转平稳，无脉动，噪声低，(五)使用场合宽，能适用于诸如旋转式空气压缩机、真空泵、容积式流量计、液流泵等物质输送，需要增(减)压、计量场合。
附图说明如下：
图1为本发明端截齿廓曲线。
图2为啮合关系图。
