Analysis of Oil Film Temperature Distribution of the High Speed Shaft Journal Bearings of Gear Box Applied in the Coal Mine Hoisting Machine

The paper describes the analysis of oil film temperature distributions that are generated in the gear train journal bearings of high speed shaft. The oil film temperature distributions were obtained on the assumption of adiabatic, laminar oil film for the finite bearing length, parallel axis of journal and bush and radial load of bearings. Maximum oil film temperature was determined based on the obtained oil film temperature distributions. The calculation were carried-out on the condition of static equilibrium position of journal.
