泵齿轮端面砂带磨削及倒棱关键技术研究
|
摘要
为了实现齿轮端面及其棱边的高效一次加工,结合新型开式砂带磨削的方案和特点,设计了一种适用于齿轮端面的砂带磨削装置。该系统既有砂带磨削的柔性和适应性广的特点,又能通过磨削参数的调节实现端面棱边微小倒棱尺寸的精确控制。磨削系统采用了接触轮的往复振动方式,能够改善砂带表面磨料等高性。最后通过磨削试验探索得到最佳表面质量和倒棱尺寸的磨削参数,表面粗糙度能够维持在0.05μm以下,棱边不同位置微小倒棱尺寸能够满足给定的尺寸范围,也验证了该系统进行高精度磨削的有效性和稳定性。
To achieve high efficiency machining of gear face and tiny chamfer,an abrasive belt grinding device suitable for the gear face was developed and combined with the new open-type abrasive belt grinding scheme and characteristics. The grinding device is flexible and adaptable for grinding abrasive belt and can be accurately control the tiny chamfering dimensions of the end edge through adjusting grinding parameters. The grinding device adopts the reciprocal oscillation mode of a contact wheel to improve the consistence of abrasive wear height. Experimental results prove that the grinding device is feasible and stable for precision grinding. The grinding parameters were optimized to obtain the best gear face quality and chamfer size; the gear face roughness is kept below 0.05 μm,and the small size of the chamfer meets the given size range requirements in different edge positions.
