Abstract In order to further improve the grinding efficiency of face gear, this paper presents a novel method for grinding face gear along contact trace using disk CBN wheel. Firstly, the grinding principle of face gear is studied, and the tooth surface equations of rack and gear shaper cutter are derived, thus formulating the tooth surface equation of disk CBN wheel. Secondly, considering the structure of the face gear grinding machine tool and the impact of the grinding wheel parameters on the face gear tooth surface, the disk CBN wheel configuration is proposed, and the calculation method of the tool position of the face gear grinding is established. Thirdly, according to the structural characteristics of the grinding wheel, the tooth surface contact trace of the face gear is designed, and the face gear development grinding processing method along the tooth surface contact traces is presented. Finally, a test of grinding spur face gear with disk CBN wheel is carried out on a laboratory-made five-axis face gear processing machine. The test results verified the correctness of the face gear grinding. Compared with the dish wheel for grinding face gear, the grinding method proposed in this paper can further improve the grinding efficiency of face gear. This method will break new ground for the engineering application of the face gear. Keywords Face gear . Disk CBN wheel . Contact trace . Grinding . Five-axis machine
1 Introduction Face gear transmission is a new advanced transmission form in which spur gear meshes with bevel gear. It has the characteristics of small size, light weight, simplified axial support, and easy power split. Face gear transmission is widely used in the fields of aerospace, engineering machinery, and marine ships, which has produced significant application effects and shows broad application prospects. Zanzi et al. investigated an approach for the application of longitudinal plunging in the manufacturing of a double crowned pinion of a face gear drive [1]. Based on standard cutting tools and standard bevel gear machines, Stadtfeld proposed the coniface process and results in short cutting times comparable with straight coniflex bevel gears [2].
