Thermal Characteristic of High Speed Motorized Spindle for Wood-Working Machines

The structure characteristics of high speed motorized spindle for wood-working machines are introduced and the mechanism of thermal deformation of motorized spindle is analyzed.The finite element analysis model of high speed motorized spindle for wood-working machines thermal characteristics is built.The static temperature field is calculated using software ANSYS.The real working conditions are simulated by step loaded transient thermal analysis and the temperature rising trend is got which can be used for temperature control of motorized spindle.By the result of simulation,the main measures to improve the thermal characteristic of the high speed motorized spindle for wood-working machines are put and references to structure design of motorized spindle are offered.
