Abstract
As one of the important parts of RV reducer, high precision eccentric shaft has been machined by X-C linkage grinding. The grinding mechanism of eccentric shaft X-C linkage is analyzed for improving the machining accuracy; the roundness error of eccentric shaft and the X and C axis compensation gains calculation method are proposed. The coupling compensation control scheme of roundness error is designed based on the prediction characteristics of feed-forward control. The X-C grinding simulation model of the eccentric shaft is established. Comparison with conventional machining, the feed-forward coupling compensation control designed in this paper, can effectively improve the roundness accuracy of eccentric axis X-C linkage grinding.
