Good day everybody,
My name is Dillen and I am a member of a formula student team in The Netherlands. Currently we are designing our first own produced planetary reduction gearbox for our electric AMK motors. The gearbox will be a stepped/compound configuration. Due to data of other formula student teams we know that these types of gearboxes can heat up to 90 degree celsius (194 F) during hard use. The housing of this gearbox will be made out of 7075-T6 aluminium. A 2 row angular contact ball bearing needs to be interferenced fitted with the outer ring into the housing. The bearing has an inner (bore) diameter of 50mm and a outer diamter of 90mm. The problem I face is how do I determine the right iso fit for the bearing seat in the housing? The aluminium housing expands alot more than the steel outer ring of the bearing. At all times i need to make sure it stays in an interference fit.
I came a cross AN tolerance rings. Does somebody have experience with these rings. And are these rings suitable for a bearing that connects the wheelhub to the gearbox housing.
Thank you in advance for your time and effort.
