Abstract:
Pair of interacting gear rims of the rotary machine including no less than one said pair of gear rims interacting with each other with creation of variable volume chambers, eccentrically located one inside the other with eccentricity e equal to the difference of the interacting surface radiuses;profile of contact surface of inner and outer gear rim has an axis of symmetry, bounded by conjugated arcs, and consisting of n>2 identical parts, conjugated among themselves; said identical part of the said inner gear rim is bounded by the arc of radius p1, conjugated at its ends with the arcs of radius q1 and of radius a+p1, where a=p1+q1, said arc of radius q1 conjugated at the other end with the arc of radius b+q1, where b>0, which is conjugated at the other end with the said arc of radius a+p1 of adjacent identical part, which completes the said gear rim profile; said identical part of the said outer gear rim is bounded by the arc of radius p2=p1+e, conjugated at its ends with the arcs of radius q2=aâˆ’p2 and of radius a+p2, said arc of radius q2 conjugated at the other end with the arc of radius b+q2, which is conjugated at the other end with the said arc of radius a+p2 of adjacent identical part, which completes the said gear rim profile.
