Abstract

The invention discloses a bidirectional cam structure comprising a driving cam set and a movable swinging rod. The movable swinging rod comprises a movable member connection end part and a cam driving end part; the cam driving end part is formed by a first, second, and third driving rod parts; the driving cam set is formed by a first cam, a second am and a driving rotating shaft; the first driving rod part is equipped with a first rolling wheel; the first rolling wheel is pivoted to the first driving rod part via a first rotating shaft; the second driving rod part is equipped with a second rolling wheel; the second rolling wheel is pivoted to the first driving rod part via a second rotating shaft; the first rolling wheel has a contact with the first cam; and the second rolling wheel has a contact with the second cam. During the work, grooved pulley function can be achieved via two forward and backward single-direction cams formed by the first and second cams; and the bidirectional cam structure has compact structure.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission devices, in particular to a bidirectional cam mechanism. Background technique [0002] As an important type of mechanical transmission structure, the cam transmission mechanism is widely used in mechanical equipment; however, for the existing cam transmission mechanism, it often encounters reset failure, which seriously affects the mechanical The stability and reliability of the equipment. Contents of the invention [0003] The purpose of the present invention is to provide a two-way cam mechanism aiming at the deficiencies of the prior art, which is novel in design, compact in structure and capable of realizing the function of a sheave. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions. [0005] A two-way cam mechanism includes a driving cam group and a movable swing rod installed beside the driving cam g...
