1 INTRODUCTION ¶)

9+e e3perimental researc+ concernin# t+e t+ermal

re#ime of planetary speed reducers is important in

order to identify t+e areas t+at ac+ieve +i#+er

temperatures0 9+e +eat produced is due to t+e friction

eteen t+e #ear flan2 profiles, t+e friction at t+e

earin#s of t+e planetary transmission and t+e friction

correspondin# to t+e luricant used0 9+e +eat t+at

results from t+ese t+ree factors is dissipated toardst+e outside enviroment, usin# conduction, convection

and radiation0 9+erefore, a natural coolin# occurs at

t+e surface of t+e planetary transmission0 ;eepin# in

mind t+e sensivity of t+e sealin#s of t+e planetary

transmission, and t+e effect of t+e t+ermal dilatation

over t+e sealin# itself, it is important to 2no t+e

surface temperature of t+e planetary transmission, as

ell as t+ermal #radients0 Also, t+e increase of t+e

temperature reac+ed durin# operation of t+e planetary

transmission leads to vapori:ation of t+e luricant,

leadin# in turn to intense friction and ear, t+ermal

crac2s and sei:ure of t+e #ears t+at form t+e planetary

transmission0 9+e t+ermal sei:ure p+enomenon

appears at +i#+ values of perip+eral speeds, t+e

decision factor ein# t+e temperature increase at

contact areas, t+e distruction of t+e luricant film and

micro-eldin# of t+e spots in contact0 As t+e result of

t+e relative motion of t+e toot+ flan2s t+ese micro-

eldments rea2 and t+en form a#ain at a ne

contact eteen toot+ flan2s ?R" 8/18, +avin# a #ear ratio of i4500

9+e otained results presented in t+is paper t+at t+e

+i#+est temperatures are ac+ieved at t+e first sta#e of

t+e planetary transmission as t+e result of t+e +i#+er perip+eral speeds of t+e sun, planet #ears and carrier0

9+erefore optimi:ation strate#ies concernin# t+e

temperature s+ould e directed toards t+e first

sta#e0 @n t+e ot+er side, optimi:ation strate#ies t+at

concern t+e flan2 play for e3ample (y s+iftin# t+e

profile of t+e sun and planet #ears) s+ould e directed

toards t+e suseuent sta#es, since t+e perip+eral

speeds are reduced y t+e ratio of t+e first sta#e, and

t+erefore +ave a lo influence on t+e overall t+ermal
