I've been using the Mechsoft Bevel Gear wizard (a Solidworks 2004 add-on) to do design plus strength checks etc for a small 3:1 10DP Bevel Gear Transmission for a small Helicopter (2 Stroke engine 2 cyl 24Hp @5000 rpm) so after finaly settling on dimensions that give the green light the Gear has an approximate Gear size of around 4.5" ... ok not so bad ! but I would like this to be as small as possible due to weight factor.
2 days ago I visited a local Marine shop and on the counter top was a bunch of Spiral Bevel gears from various makes and models of outboards ... one of the gears I picked up was approx 3" and from a 40 Hp Suzuki, these do have a reasonably generous face width of around 3/4" to 1' or so.
Is mechsoft over doing the strength check ?
I need reliability but not the beef factor and I'm curious as something seems off here ?
looking at several Co's who make gears there also seems to be a wide gap in strengths due to material's and Hardness etc when trying to compare products with similar load and speeds.
I'm curious as to what others out there would consider a suitable DP or Module for a 3:1 Gear set with 24Hp at 5000 Rpm ?
TIA
