FIELD: machine building. ^ SUBSTANCE: drive chain consists of internal plates (3) stationary connected with insertions (4) and of external plates (1) stationary connected with rollers (2). Pitch by axles of rollers for internal and external links is different. Here are disclosed formulas for determination of chain pitch for internal links, for external links and for nominal pitch. ^ EFFECT: low specific quantity of metal, high reliability, absence of rollers at simultaneous reduction of gear teeth wear, raised carrying capacity of joints, low noise. ^ 2 dwg |
