<p>PCT No. PCT/US88/00853 Sec. 371 Date May 25, 1990 Sec. 102(e) Date May 25, 1990 PCT Filed Mar. 21, 1988 PCT Pub. No. WO89/05933 PCT Pub. Date Jun. 29, 1989.A differential gear assembly of the type used in automotive and truck axles having multiple gear trains for interconnecting axle ends is provided with gearing components having a particular relationship between tooth numbers for simplifying assembly requirements of the differential. For example, each gear train includes a pair of combination gears (40, 50) formed with center worm wheel portions (42, 52) and first (44, 54) and second (46, 56) spur portions at either end. The tooth numbers ns of the spur portions (44, 54 and 46, 56) are made an integer multiple k of the tooth numbers n of the worm wheel portions (42, 52) of each combination gear (40, 50). The relationship can be expressed as follow: ns=k-n; k>1 and an integer=2(N.k)/w and N=no. of side gear teeth W=no. of gear trains This enables the respective gear trains w to be assembled in a properly timed relationship at an expanded number of easily recognizable rotational positions.</p> |
