wheel bearing
4.In this paper,the load acted on the outer ring of flexible bearing and on the ball has beensolved on the premise that it is considered that the flexible wheel and bearing effect distor-tion under the action of outer loading torsion on harmonic gear drive. According to thesolved load and with formulas concerned and theorems,the analysis has been made of allkinds of stress on the outer ring of flexible bearing and the conclusion more suitable for re-ality has been obtainde.

7.The 200 MW steam-turbo units in Shajiao A Power Plant have the problems of low oil pressure of the main oil pump, wear and tear of the cog-wheel coupling and thrust bearing, automatic switching inability of the pump system, etc. , which seriously impact the safety and reliability of the units.
9.Because of wearing of worm gear pair and lubricating failure of tip box,mounting failure of bevel gear wheel of high speed shaft of epicyclic rdeucer casing,diffcult bearing rotation,etc,the integral service life of chut drive housing of non bell top of 750m~3 blast furnace in Laiwu iron and steel Co. ,Ltd is shorted.
