Spur-Gear-System Efficiency at Part and Full Load [PDF]
A simple method for predicting the part- and full-load power loss of a steel spur gearset of arbitrary geometry supported by ball bearings is described. The analysis algebraically accounts for losses due to gear sliding, rolling traction, and windage in ...

Performance of jet- and inner-ring-lubricated 35 millimeter bore ball bearings operating to 2.5 million DN [PDF]
Parametric tests were conducted with a 35 millimeter bore, angular contact ball bearing having a single outer land guided cage. Lubrication was achieved by flowing oil through axial grooves and radial holes machined in the inner ring of the bearing. Test

Operating limitations of high speed jet lubricated ball bearings [PDF]
A parametric study was performed with 120-mm bore angular-contact ball bearings having a nominal contact angle of 20 degrees. The bearings had either an inner- or an outer-race land riding cage, and lubrication was by recirculating oil jets which had ...
