A special-shaped circular slider combination kinematic mechanism

Abstract

The invention discloses a special-shaped round sliding block assembly movement mechanical mechanism. The special-shaped round sliding block assembly movement mechanical mechanism is characterized in that a round sliding block assembly, a linear movement assembly, a crankshaft, a machine body and the like are included; eccentric holes of the round sliding block assembly are combined with a crankshaft neck of the crankshaft, a friction pair is arranged between the eccentric holes of the round sliding block assembly and the crankshaft neck of the crankshaft, and the outer circles of round sliding blocks are combined with the linear movement assembly through the friction pair; the round sliding block assembly comprises the round sliding blocks, the eccentric holes, a connecting pair and bearing bushes; and the linear movement assembly is arranged on the outer diameters of the round sliding blocks and comprises a cross head, a guide rail, the arc friction pair, holes, a transmission rod, a knuckle bearing, a plunger rod, a self-aligning bearing and the like. The special-shaped round sliding block assembly movement mechanical mechanism has the beneficial effects that the two round sliding blocks can work independently, power can be transmitted to the corresponding round sliding blocks, redundant movement connection of the two round sliding blocks is released, movement components and friction pair restraints in the structure are reduced, friction of a movement pair is lowered, and mechanical movement can be more smooth and more durable.

Description

technical field [0001] The invention belongs to the field of sports machinery, and in particular relates to a special-shaped circular slider assembly sports machinery mechanism. Background technique [0002] The clam-line motion of the circular slider is a good theory in mechanical motion. It has been proposed at home and abroad for hundreds of years, and many scholars have also conducted various researches. However, it has not been well developed and substantively applied so far. The core technology of the clam-line motion of the circular slider is to replace the traditional crank-link mechanism with a motion mechanism such as a circular slider, which has the advantages of simple structure, small size, stable operation, and low noise. Clam line motion is a combination of reciprocating motion technology and rotor motion technology. In the current clam line motion mechanism, the conjoined circular slider structure has the following problems: [0003] Because there are activ...

AI Technical Summary

Problems solved by technology

Now research or experiment with circular slider clam line movement, the used conjoined eccentric circular slider is rigidly connected or integrated, which produces mechanical movement constraints, and the parallel axes of the rotating moving parts have irregular angles when they are running, resulting in axial force , to accelerate the wear of each kinematic pair and friction pair, resulting in oil heating and mechanical performance degradation
