The flexible external tooth car which in the rigid internal tooth car

摘要

Wave gear device (1), from the movement locus for the teeth (2) rigid internal gear teeth in (34c) principal section of κ = 1 coefficient deflection flexible external gear (3), both gears (2, 3 to obtain a similar curve tooth that used to define the addendum tooth profile). I was subjected to a dislocation corresponding to the difference between the κ coefficient deflection principal section of (34c) from the similarity of these curves, and κ _{o (} 1) coefficient deflection open end cross section flexible external gear (3) of (34a) to obtain the tooth profile curve, to form addendum tooth profile portion of the two gears (51 and 41) by using these. The inner composite tooth profile of the tooth height, which is defined straight tooth part and addendum tooth profile portion 51 and 41, were connected to these and (52 and 42), tooth root tooth appropriate portions of that to avoid interference and (53,43) I the tooth (24), external teeth (34) teeth. In addition, the two gears having regard to the Corning of the flexible external gear, and over the teeth muscle whole is subjected to a negative dislocation open end cross section flexible external gear (3) from (34a) inner end cross-section through (34b) I have realized the engagement reasonable.
