RETRACTED: Analysis of temperature change mechanism and temperature rise characteristics of dry hobbing machine tool under heterogeneous energy conversion

Abstract

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.
