Abstract

FIELD: mechanical engineering; manufacture of pumps and compressors. SUBSTANCE: during rotation of rotor, two rollers enter and leave in turn grooves in housing and rotor, thus changing the working volume of machine between housing, end plate, fixed roller fitted in housing and movable roller received by rotor groove. Geometry of grooves provides change-over based on theory and practice of cam mechanisms and overrunning clutch. Geometry of grooves in housing and in rotor shall ensure change-over of rollers at their geometric closing and geometry of rotor groove excludes seizing of rotor roller since tangent angle of groove and rotor exceeds angle of seizing; grooves have smooth change-over, without sharp edges. EFFECT: enhanced durability.

Изобретение относится к области машиностроения и может быть использовано при создании насосов, компрессоров. Два ролика при вращении ротора попеременно заходят и выходят из выемок то корпуса, то ротора, при этом меняется рабочий объем машины, заключенный между корпусом, торцовой крышкой, неподвижным роликом, находящимся в корпусе, и подвижным в выемке ротора. Предлагается геометрия выемок, обеспечивающая переход, исходя из теории и практики кулачковых механизмов и обгонной муфты. Геометрия выемок корпуса и ротора должна обеспечить переход роликов при их геометрическом замыкании, а геометрия выемки ротора исключает заклинивание ролика ротора, т.к. угол касания выемки и ротора больше угла заклинивания, при этом выемки имеют плавные переходы без острых кромок, что повышает долговечность механизма.The invention relates to mechanical engineering and can be used to create pumps, compressors. When the rotor rotates, two rollers alternately go in and out of the recesses of either the housing or the rotor, while the working volume of the machine, enclosed between the housing, the end cover, the stationary roller located in the housing, and the movable in the recess of the rotor, change. The geometry of the recesses is proposed, which provides a transition, based on the theory and practice of cam mechanisms and overrunning clutch. The geometry of the notches of the housing and the rotor should ensure the transition of the rollers when they are geometrically shorted, and the geometry of the notches of the rotor eliminates jamming of the rotor roller, because the contact angle of the recess and rotor is greater than the jamming angle, while the recesses have smooth transitions without sharp edges, which increases the durability of the mechanism.
