<p><P>PROBLEM TO BE SOLVED: To reduce gear noises by reducing an error in transmission of hypoid gears. <P>SOLUTION: In a pair of hypoid gears of first and second gears, errors in transmission are measured actually and plotted while displacing the second gear. By errors in virtual transmissions, intermediate parts between errors in actual transmission are interpolated to prepare a transmission error curve C1 by connecting the errors in actual and virtual transmissions. The area of the part surrounded by the transmission error curve C1 and a greatest allowance (a straight line M) of transmission errors is determined, and virtual partition lines N1, N2, N3 are drawn from the straight line M to the transverse axis so that the part in question may be divided at a specified area ratio. The hypoid gear 10 is constituted with the transverse coordinates of intersections of the transverse axis and the partition lines N1, N2, N3 as positions of the second gear 14, that is, as those of meshing of the first and second gears 12, 14 to determine acceptable quality levels respectively. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
