2919 Bearing Strength of Skew Cylinders

Abstract

The meshing of the crossed helical gears is theoretically considered to be a kind of point contact. The contact brings big power loss and frequent wearing. So, it is used as a motion transmission because of the small load capacity and the low efficiency. However, it may be perform the power transmission, if the contact area of the crossed helical gears increases according to the time passing. However, the contact of crossed cylinders has not tested yet so much. The purpose of the paper is to evaluate the effect of each factor of the scoring strength with the crossed cylinders testing machine. In this study, the operating time was investigated under various conditions of relative sliding velocity and hertzian pressure. The new tendency for the scoring strength was observed by the result of this investigation.
