The 3D f in ite e em entm ode o f spur gear tran sm ission for th erm a ana ysis has b een estab ish ed b ased on uti ization of heat transfer theory, friction th eory and gear m esh ing theory. By adopting infin ite e em entm ethod, the tem p erature distribution, th erm a distortion, and th erm a stress of th e spur gear driving under h igh o i tem p erature fau t state are ca cu ated. T he variation regu ation of tem p erature fie d and th erm a deform ation are ana yzed, and th e frequency and distortion of th e gear are ca cu ated. Th e der ived resu ts sh ow th e changes o f sh ape, disp acem ent and equ iva ent stress under norm a frequen cy and ab norm a frequ ency. Th e research resu t isw orth to be con su ted in fau t diagno sis of gear box in w ind turb ine generating un its.
