1338610 Sets of toothed gear boxes HANSEN TRANSMISSIONS INTERNATIONAL NV SA 7 Dec 1970 [11 March 1970] 57946/70 Heading F2Q A set of n (e.g. 10) gear speed reducers A, B, &c. each having an input gear, an output gear, and a plurality of intermediate gears, the distances a 00 , a 0 , a 1 &c. between the centres of successive intermeshing gears, increasing from the input to the output gear, has the distances a 1 , a 2 &c., between the centres of the output gears and the gears meshing with them forming a progression of which the ratios between terms form a geometric progression, i.e. a 2 /a 1 = h 1 ; a 3 /a 2 = h 1 p; a 4 /a 3 = h 1 p<SP>2</SP>; &c. For example h 1 = 2; p is less than 1; a 00 and a 0 are also in the series but not necessarily adjacent terms; the set of speed reducers may have maximum permissible output torques ranging from 90 to 7000 mkg. |
