Hello, gentlemen! I would like to ask, if someone can point me to some source of information, how to design and calculate wave reducers.
I am doing this for my school project. I have a book, which has all the formulas etc, but I am stuck with three errors already and I do not have any other source of this information to verify, if the error is in my brain or in the book. Few examples: 1) there is formula for involute function of pressure angle between gear hob and the gear (that is needed to calculate correction for flexible gear). One of the elements in that formula is correction ratio x_2; The formula for calculating x_2 is given as well. And guess what, one of elements in that formula is the involute function of pressure angle between gear hob and the gear. So there is magic circle, 2 unknown values depending each on other. But I managed to solve that. 2) there is some mysterious ratio in 2 formulas for wave generator profle parameters and correction ratio for internal gear without any explanation, what is it and how it is calculated. 3) the formula for efficiency ratio is doomed already before starting to calculate it: n=1/(1+a+2,2*10^5*u) a - not explained, what is that, but it is given that for flexible bearing a=0,14 u - reduction ratio, u = 89 It does not really matters, because 2,2*10^5 means that the efficiency is virtually non-existent. 4) Wave generator is elipse, expected ovality (d1 - d2)/2 should be around value of modulus of teeth, which in my case is 0,7, but I am getting 0,17, which just means that the gears will remain engaged all around their perimeters, which is failure. I have been trying to find something in the international databases we have available through school's library IT tools, but no luck. Googling just gives me total rubbish. Obviously I fail at choosing correct keywords. Can You point me to some place, where I could find, how to design and calculate wave reducer? All the flexible gears, flexible bearings etc. Thanks!
