Bisection moving rocker arm mechanism driven by worm wheel and worm

Abstract

The invention discloses a bisection moving rocker arm mechanism driven by worm wheels and a worm, which comprises a worm, a left worm wheel, a right worm wheel, a left rocker arm, a right rocker arm, a left shaft and a right shaft, wherein the worm is respectively meshed with the left worm wheel and the right worm wheel; the left worm wheel and the right worm wheel are respectively rigidly connected with the left rocker arm and the right rocker arm; the center line of the left shaft and the center line of the right shaft are respectively coincident with the center line of the left worm wheel and the center line of the right worm wheel; the left shaft and the right shaft are respectively fixedly connected with the left rocker arm and the right rocker arm; the left worm wheel and the right worm wheel are driven by the worm to rotate relatively to the respective center line, i.e. the left shaft and the right shaft; and the left rocker arm and the right rocker arm fixedly connected with the left worm wheel and the right worm wheel are driven to respectively move relatively to the left shaft and the right shaft so as to realize the moving bisection of the two rocker arms. The bisection moving rocker arm mechanism driven by the worm wheels and the worm has the advantages of compact structure, excellent performance and good application prospect in the technical field of machinery and automotive engineering, and the bisection movement and the self-locking function of the mechanism can be realized.

Description

technical field [0001] The invention relates to a mechanical rocker mechanism, in particular to a turbine and worm driven bisecting motion rocker mechanism, which is a rocker mechanism capable of bisecting motion and belongs to the technical field of machinery and automobile engineering. Background technique [0002] The rocker arm mechanism is widely used in the field of mechanical and automotive engineering technology. Its main form is that a certain point in the middle of the rocker arm is hinged, which can realize the movement arm rotating around the hinge point. Now it is mainly used in the coal mining device of the coal mining machine, and the valve control in the engine device, as well as in the landing gear of the aircraft. Most of the existing rocker arm mechanisms use an oil cylinder structure to drive the rocker arm to rotate, or a pull rod mechanism to drive. These structures occupy a large space, are not compact enough, and cannot realize the self-locking functi...

AI Technical Summary

Problems solved by technology

Most of the existing rocker arm mechanisms use an oil cylinder structure to drive the rocker arm to rotate, or a pull rod mechanism to drive. These structures occupy a large space, are not compact enough, and cannot realize the self-locking function. Poor safety performance

Moreover, in the existing rocker arm structures, most of them realize the movement of a single rocker arm. In some cases where two rocker arms or even multiple rocker arms are required to move together, the functional requirements cannot be met.
