Abstract

Spiral bevel gears are manufactured and used in pairs. When one part usually pinion fatigued, the pair will be replaced. It inevitably leads to a waste of resources and time. To solve this phenomenon, a method to remanufacture pinion with ease-off topology modification is proposed. First, the wheel and pinion were measured to fitting tooth surface, and then a conjugate surface of wheel fitting tooth surface was derived. Secondly, an ease-off topology surface was superimposed to the conjugate surface to improve mesh performance, and then a design tooth surface was obtained. Thirdly, a mathematical model to process pinion was established and original machine-tool settings parameters of pinion were calculated. The deviations between design and original tooth surface of pinion were count, and an error correction model of tooth surface was established to adjust machine-tool settings parameters. Finally, an experimental verification was conducted. The pinion was remanufactured by a face-milled generator and the mesh performance was consistent with design. The result demonstrates the method proposed is effectiveness and feasible. It provides reference for the remanufacture of large-size spiral bevel gears and has good value for engineering application.

一种利用面铣削铣床对大尺寸螺旋锥齿轮进行缓动拓扑修饰的再制造方法

螺旋锥齿轮是成对制造和使用的。通常当一个零件齿轮疲劳时，副将被更换。这不可避免地会导致资源和时间的浪费。针对这一现象，提出了一种缓脱拓扑修饰的小齿轮再制造方法。首先对轮齿和小齿轮进行拟合齿面测量，然后推导出齿轮拟合齿面共轭曲面。其次，在共轭曲面上叠加缓脱拓扑曲面以提高啮合性能，得到设计齿面;第三，建立了小齿轮加工的数学模型，计算了小齿轮的原始机床设置参数。计算了齿轮设计齿面与原齿面偏差，建立了齿面误差修正模型，对机床设置参数进行了调整。最后进行了实验验证。用面铣发电机对小齿轮进行了再加工，啮合性能与设计一致。结果表明，该方法是有效可行的。为大尺寸螺旋锥齿轮的再制造提供了参考，具有较好的工程应用价值。
