thread727-250309: Analysing FEA Gear Box Housing
Experts,
I have some doubts in doing a FEA analysis of housing with bevel gears.I hav taken the housing along with gears n bearings and applied the resulting radial loads on the bearings as two components one as the horizontal and the other vertical and the axial load of the bevel gear directly on the housing.I have 2 bearings each on the bevel gear.I am facing diffuclty in judgin the horizontal and vertical radial reaction directions which need to b applied on the bearings.(Note this radial reactions r got from some program).I hav attached a picture for reference. My doubt is whether the bearing reaction at location 2 & 3 will be in same or opposite reaction. My guess is it should be in opposite.I would also like to know the direction of reactions at 1 & 4.
Thanks

RE: Housing FEA analysis
remember there are two forces acting along that line of action (force and reaction). how to tell which one applies to which gear ? ... one gear will be driving the other, no? so one gear is loading the other, yes?
as for the reactions, wouldn't they be like a beam with an overhang load ?

one side (1&2) is loading the other (3&4),
so you can draw a free body that shows the loads at 1 & 2 being reacted by the contact force supplied by the other gear (ie reacting the driving force).
now your friend Might be saying that the loads at 1&2 are the same as the loads at 3&4 ... we've been saying that the loads at 1&2 are reacted at 3&4. these are the same thing, only expressed differently !?
