Driving structure based on eccentric shaft

Abstract

The invention discloses a driving structure based on an eccentric shaft. The driving structure comprises a base body with an inner cavity, a driven part movably assembled in the inner cavity and an eccentric shaft in linkage fit with the driven part, the eccentric shaft comprises a first rotating shaft part and a second rotating shaft part which are coaxially arranged, an eccentric shaft part which is arranged between the first rotating shaft part and the second rotating shaft part and eccentrically arranged is further included, the diameter of the first rotating shaft part is larger than thediameter of the second rotating shaft part, a first shaft hole penetrating through the interior and the exterior is formed in the side wall of one side of the inner cavity of the base body, a second shaft hole is formed in the position, opposite to the first shaft hole position, of the other side wall of the inner cavity, the diameter of the first shaft hole is larger than that of the second shafthole, the first rotating shaft part is rotatably matched with the first shaft hole, the second rotating shaft part is rotatably matched with the second shaft hole, and the eccentric shaft part is inlinkage fit with the driven part. The base body forming of the driving structure is easier, the production cost is effectively reduced, the eccentric shaft and the base body can be more easily mounted, and the assembling efficiency can be greatly improved.

Description

technical field

[0001] The invention relates to the technical field of mechanical transmission, in particular to a driving structure based on an eccentric shaft. Background technique

[0002] In the prior art of mechanical transmission structures, it is a common form to convert the rotational motion of the shaft into the sliding motion of the driven part relative to the base through the eccentric shaft. The existing eccentric shaft is usually provided with a first shaft part, an eccentric shaft part and a second shaft part in sequence along the axial direction, the first shaft part and the second shaft part are coaxial and have approximately the same diameter, and the eccentric shaft part is opposite to the first shaft part The coaxial eccentric arrangement of the part and the second rotating shaft part. Since the diameters of the first shaft part and the second shaft part are approximately the same, the size of the two shaft holes matched with the first shaft part and the ...
