Aiming at the problem of thermal deformation of dry hobbing machine, this paper focused on the study of temperature change mechanism and temperature rise characteristic. By analyzing the heat generation characteristics under the energy conversion of multivariate heterogeneous energies such as electric energy, mechanical energy, and hydraulic energy, a whole process heat transfer model was established to reveal the complex heat transfer mechanism of the dry hobbing machine. Through the combination of infrared thermal imaging and sensor online temperature measurement method, the temperature of key points of dry hobbing machine were measured during the dry hobbing of an automotive gear. To obtain the temperature rise curve of the machine tool, Python was used for experiment data processing. On this basis, the temperature rise characteristic of dry hobbing machine was discussed. The results can provide support for the thermal deformation control and thermal balance design of dry hobbing machine.

“…The hob and the gear wheel are rotated in spatial according to the strict transmission ratio to form the gear tooth profile. At the same time, the axial feed of the hob relative to FS forms a full tooth width (Yang et al, 2018;Zhao et al, 2021). Similar to the hobbing process, in the CM process, the FS rotation is the main movement (autorotation around the Z axis), which rotates continuously around the axis at a constant speed.…”

Strain wave gear, also known as "harmonic drive" is widely used in the industrial robotics field due to the excellent deceleration performance. The tooth modification of the flexspline faces the requirements of high accuracy and service life. In this paper, a novel spatial tooth profile modification method along the circumferential direction of flexspline for strain wave gear is proposed. The circumferential modification method has a small change of meshing point position and working pressure angle, which is beneficial to maintain the transmission accuracy and improve the service life. In addition, the relation model of spatial motion between hob and flexspline, and the relation between tooth profile and modification quantity are study in the view of engineering application aim to reveal that the principle of circumferential modification is the rotation of the tooth profile along the center of the tooth apex circle. And the feasibility of circumferential modification is verified by a actual machining. Then, two main factors, circumferential modification quantity and radius of flexspline indexing circle are analyzed. Afterward, the novel stepwise modification of the circumferential spatial tooth profile of flexspline is introduced. Finally, a case study of circumferential spatial tooth profile modification of flexspline for strain wave gear is conducted. The case study shows that the maximum distance offset value in circumferential modification is 7.8 μm, which is smaller than the traditional modification value (13.2 μm), and the maximum working pressure angle value is 2.24 °, which is smaller than the minimum value (3.93 °) in traditional modification. And the FEM results and the cross-section tooth pairs comparing with the theoretical model also show the possibility of the proposed modification method.

Harmonic drive is widely used in the industrial robotics field due to the excellent deceleration performance. The tooth modification of the flexspline in the harmonic drive faces a great challenge. In this paper, a novel spatial tooth profile modification method along the circumferential direction of flexspline for a harmonic drive is proposed. Through the hob circumferential offset, the tooth profile rotates and the tooth thickness of interference part is reduced, then the spatial meshing is realized. The circumferential modification method has a small change of meshing point position and small pressure angle, which is beneficial to maintain the trans-mission accuracy and improve the service life of the harmonic drive. In addition, the relation model of spatial motion between hob and flexspline, and the relation between tooth profile and modification quantity are studied. Two main factors, circumferential modification quantity and radius of flexspline indexing circle on circumferential modification are analyzed. Afterward, the novel stepwise modification of the circumferential spatial tooth profile of flexspline is introduced. Finally, a case study of circumferential spatial tooth profile modification of flexspline for harmonic drive is conducted to show the advantages of the proposed modification method.
