Abstract
The present work is an endeavor to investigate analytically and experimentally the film thickness variation during teeth mesh in spur gears. The analytical approach simulated gears mesh by equivalent rigid discs. Both hydrodynamic and squeeze actions contribute to lubricant film formation. The contribution of squeeze action is more effective in gear lubrication than that due to hydrodynamic action. The complicated dynamic and contact conditions in gears during power transmission dictate the variation of generated film thickness values between meshing gears’ teeth. Experimentally, a specially designed test rig with associate measuring techniques were constructed. Attained results were recorded and analyzed. Experimental results showed that the oil film thickness decreases through mesh period to a minimum at theend of gears teeth mesh which confirm the analytical predictions.
