FIELD: machine building.SUBSTANCE: gear hydraulic unit includes gears, teeth 2 of which are made of thin-wall plates and located in a chamber formed with a housing and side discs. Cavities are located on end surfaces of discs in suction and discharge zones. Thin-wall plates are made from elastic material and each tooth 2 of gears is equipped as to height with cone-shaped slot 3. Slot 13 is located in central part of tooth 2. Vertexes of slots 13 are directed towards rotation axis of each of the gears. Conjugation lines of cavities and side discs have curved shape. Width of teeth 2 of gears from their pitch line towards heads owing to availability of slots 13 is higher than width of tooth 2 root.EFFECT: improving productivity of a hydraulic unit and reducing pulsations of working liquid flow supplied to an actuator of the hydraulic unit, where it is used.5 dwg |
