CLASSIFICATION OF THE ADJUSTABLE TOOTH-LEVER MECHANISMS OF PERIODICAL TURN AND A MODERNIZED METHOD OF REGULATING ANGLE

The current method of controlling the duration of stops in the drives of periodic rotation of automatic machines and its constructive realization in the form of a gear-lever mechanism based on non-circular gear wheels were proposed. Additional design parameters have been determined, making it possible to adjust the gear-lever mechanism to different angles of the output shaft with no change in the lengths of the links of the basic lever mechanism. The essence of the proposed method of controlling the angle of emergence gear-lever mechanism is that in the process of turning the leading link mechanism rotation on the driven shaft is transmitted through non-circular gears, resulting in a change in the conjugate radii of the initial circles of the engaged gear pairs. A classification of possible variants of the structure of adjustable gear-lever mechanisms with non-circular gears was given.
