Thermal Structure Coupling Analysis of Lathe Built-In Electric Spindle under Intermittent Load

Abstract:

Built-in electric spindle has been the core component of machine tool, whose temperature problem is serious. Internal heat source are greatly influenced by load. Based on which has the function of automatic clipping chuck inversion type vertical lathe built-in electric spindle prototype as the research object, using the theory of thermal stress and finite element, established the intermittent load cases hot - structure coupling numerical analysis model of the electric spindle. After overall analyzing electric spindle within the transient temperature field under the action of the intermittent load, the winding temperature changing with time curve is given. On that basis, electric spindle thermal deformation has been carried on the analysis and calculation, gets the shaft extension end axial thermal deformation, provides theoretical basis for the thermal error compensation.
