Hello, I have to decide and give dimensions to two covers of a helical gear box. The pinion and the second shaft (with the gear) are supported on bearings on each side. (cover) Does anyone have a recomendaiton on the best way to do it? I thought on rought (or small) bore diameters of each cover and then assembly of the two covers and final machining of the two bores on each part. Is there a simpler but still good option as this one? (Maybe less complex..In my way I think there are at least two stages: 1. each part machining. 2. Assembly and bores final machining 3. final machining of each part on the inside - chamfers etc.) Thanks!
