SU1237834A1 - Mechanism for converting rotary motion to reciprocating motion - Google Patents

Description

The invention relates to mechanical engineering, in particular to mechanisms for converting rotational movement into reciprocating.

The purpose of the invention is to increase the reliability and expansion of kinematic possibilities by reducing the contact stresses in the links of the mechanism and due to the large number of combinations of the shape of the working surfaces of the glasses.

FIG. 1 shows a mechanism for converting rotational motion into reciprocating at the beginning moment of motion; in fig. 2 is the same at the final moment of movement in FIG. 3 is a section A-A in FIG. 2, FIG. 4 is a section BB in FIG. 2, FIG. 5 is a sectional view BB in FIG. 2, FIG. 6 is a view of FIG. 2,

The mechanism for converting the rotational motion into reciprocating includes a housing 1, a driving link 2 installed therein, made in the form of a sleeve, glasses 3 rigidly connected with it, working surfaces 4 of which are multi-faceted, intermediate link 5 and a driven link 6 s cylindrical grooves 7 at an angle to the axis of rotation of the driving link 2.

Intermediate link 5 is made in the form of balls installed in the grooves 7 of the driven link 6 and interacting with the working surfaces of the cups 3.

The mechanism works as follows.

When the driving link 2 with the glasses 3 rotates, the torque is transmitted to the balls of the intermediate link 5 through the edges of the working surfaces 4 of the glasses 3, which, moving along the grooves 7 of the follower link 6, transfer the reciprocating motion to the latter.

With this rotation of the drive link with the cups 3, as the balls of the intermediate link 5 move in the grooves 7, the follower link 6 performs a full 8-fold reciprocating motion, depending on the number h of the faces on the working surface 4 steel 3.
