Cnc Spiral Bevel Gear Lapping Machine Tool Technology

This paper does some profound researches on the key technology of manufacture CNC bevel and hypoid gear lapping machines. Firstly, the mechanism of cutting process of lapping was studied. The lapping movement mode of Swinging Pinion Cone and the V&H Check were proposed. Based on the gear mesh theory and tooth contact analysis, the relationship between V&H adjustment and the movement of contact pattern and the theory of backlash control were analyzed. Then some criterions of evaluating the effect of lapping were given. Secondly, based on the V&H Check mode, the implementation details of full flank lapping movement were discussed, which include full flank lapping movement control technology, lapping effect control technology, gearset auto mesh technology, auto backlash detection and setting technology, auto runout detection technology, auto nicks and burrs detection technology, and so on. Thirdly, the paper studies about the compound supply system, which is a very important system of a CNC bevel lapper. In this section, the components of the compound were analyzed in the paper and how they influence the lapping effect. And based on the analyses of the compound system, a compound supply system with perfect function is designed. The CNC bevel and hypoid gear lapping technology discussed in this paper guides the trial-manufacture of a CNC bevel and hypoid gear lapping machine. Finally, some lapping experiments on the Gleason PHOENIX 600 HTL Turbo-Lapper were done. The performance of the trial-manufacturing CNC bevel and hypoid gear lapping machine is obvious. It also proves that the lapping technology provided in the paper is true, which can be applied in the modern CNC bevel and hypoid gear lapping machine.
