    Oil film between rollers in full complement bearing

    Unfortunately I don't have Hamrock & Dowson handy, however the argument goes along these lines: Whatever the relative speed between the two objects you are trying to build a film between you need a route to get oil into that contact. A classic journal (plain bearing) gives that (like in some...

    Oil film between rollers in full complement bearing

    On the basis of some discussion with manufacturers, it appears that for signicant acceleration fields as in our design, an outer-ring guided cage would be more in our interests. It was argued that the caged arranged would provide more effective entrapment of the oil between sliding contacts...

    Oil film between rollers in full complement bearing

    Thanks English Muffin. True - the cage has been the area of concern. I would like to determine what the critical speed and loading conditions would be for the full complement option.

    Oil film between rollers in full complement bearing

    Thank you - that is precisely the point I hope to be able to illustrate by means of some analysis from first principles. I would like to be able to do the hydrodynamic calculations to derive the expected oil film thickness for the particular application with our given the roller speeds, loads...

    Oil film between rollers in full complement bearing

    Thanks for that - I'll see if I can dig it up. Anything online specific to this problem? With thanks Francis

    Oil film between rollers in full complement bearing

    Would anyone be able to direct me to references on the topic of calculating the lubrication characteristics in full complement roller bearings, with particular reference to the oil film thickness between the counter-rotating surfaces at rolling element contact. The application involves a planet...
