FIELD: machine building.SUBSTANCE: chain gear consists of a roller chain with even number of links, and of chain wheels with even number of teeth. The pitch of internal links (t1) is greater than the standard pitch (t) and respectively the pitch of chain wheel teeth is increased. Circumferential width of one tooth (1) out of each pair of adjacent teeth (1, 2) is increased. Wedge angle of widened teeth is greater than the standard wedge angle and is determined according to the proposed dependence.EFFECT: invention allows for the improvement of chain gear operation kinematics and increase of its service life.2 cl, 2 dwg |
