GEAR

摘要

FIELD: machine building. ^ SUBSTANCE: gear consists of driving and driven tooth spiral wheels. Teeth of the driving wheel do not have dedendums. The teeth of the driven wheel are formed with recesses. At end cross section of wheels radius R of curvature of addendum of the driving wheel is constant and is equal to constant radius of curvature of the conjugated to it recess of the driven wheel. In normal cross section the tooth of the driving wheel has a profile of half of ellipse with radial arrangement of its bigger axis. ^ EFFECT: maximum allowed load capacity. ^ 5 dwg
