GEAR CLUTCH Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention relates to rigid compensating clutches designed for connection of shafts with angular and parallel misalignment of axes in heavy-load transmissions with big angles of misalignment of connected shafts. Proposed clutch has clutch members with external outer barrel teeth and cage with involute internal teeth in meshing with external teeth. Pitch circle radii of involute profiles of tooth spaces in cage exceed pitch circle radius of clutch member teeth. Centers of pitch circles of tooth space profiles lie on intersection of their axes with circumference whose center lies on axis of cage. Pitch circle radius of cage tooth space profiles is found from equation r₂=r₁+(1.125…1.6)where r₂ is pitch circle radius of cage tooth spaces; r₁ is pitch circle radius of clutch member teeth; b is length of clutch member teeth.

EFFECT: increased service life and load capacity of clutch.
