Abstract

The invention relates to motion converters with an oblique washer and can be used in pneumatic and hydraulic motors. The purpose of the invention is the improvement of manufacturability and the elimination of "dead positions by supplying the mechanism with additional shafts. When pressure is applied to the cavity above the slider 2, the concentric 11 and eccentric 5 shafts will begin to turn. The shaft 5, shifting upward, informs the slider 2, so that the eccentric shaft 6 begins to shift upward, turn the concentric shaft 12 and rotate itself. After turning the slider 2 by 180 ° amp; pressure is applied to the lower cavity, and the cycle repeats. The mechanism is reversible, i.e., the shafts of 11, 12, 1 nfl, 4 Il can be the leading links. and (L co 05 tsD 00 oo 4

Description

The invention relates to mechanical engineering, namely to converters of one type of movement into another, and can be used, in particular, in pneumatic tools and hydraulic motors.

The purpose of the invention is to increase the efficiency of me. Khanizm by eliminating "dead positions in the process of work, which increases the efficiency of its use.

FIG. 1 shows the mechanism with the slider in its extreme upper position, a longitudinal section; in fig. 2 - mechanism with a slider in its lowest position, a longitudinal section; in fig. 3 is a section A-A in FIG. one; in fig. 4 shows a graph of the dependence of Mcr on the output shaft versus the angle of the sliding angle of the slider, where the shaded indicates an additional value of L k. the equalizing total MKRMechanism contains a cornus 1 with a cylindrical straight line yushi, placed in it with the possibility of rotation and reciprocating motion, an o-rim 2, made in the form of a cylinder with inclined parallel to each other 3 and 4, and eccentric shafts 5 and 6, edged to the slider 2, the ends 7 and 8 of which are parallel to the ends 3 and 4 of the slider 2 and interact with them, while the other ends 9 and 10 are inclined, parallel to each other and turned relative to the ends 3 and 4 of the slider 2 by 90 °. Concentric to the slider 2 in the housing 1 additional shafts 11 and 12 are placed, the inner ends 13 and 14 of which are parallel to the ends 9 and 10 of the eccentric shafts 5 and 6.

The mechanism works in the following way.

When pressure P is applied to the upper cavity above the slider 2, the latter, descending, puts pressure on the end 7 of the eccentric shaft 5. Since the end 9 of the shaft 5 and the end 13 of the concentric shaft 11 are turned relative to the end 7 by 90 °, the shaft 11 and him and shaft 5 begin to turn. At the same time, the shaft 5, together with the slider 2, shifts downward and, exerting an end 7, pressure on the end face 4 of the slider 2 causes the slide to be inserted as well. When moving the slider 2, the eccentric shaft 6, mixing up, acts on the end face 14 concentric of shaft 12, giving it a challenge, and at the same time turns itself.

When the slider 2 rotates 180 °, the pressure P is supplied to the lower cavity under the slider 2, as a result of which the cycle repeats.

Thus, the reciprocating movement of the slider 2 is converted into reciprocating and vrasive movements of the shafts 5 and 6 and into the revolving movement of the shafts 11 and 12 with a practically constant torque.

The turning of the inclined ends on the eccentric shafts 5 and 6 by 90 ° relative to each other excludes their "dead positions." To obtain the reverse, the eccentricity of shafts 5 and 6 should be changed to the opposite. The message to the shafts 11 and 12 of forced rotation from an external drive allows their rotational movement to be converted into reciprocating and rotating movements of the shafts 5 and 6 and the slide 2.
