Abstract

PROBLEM TO BE SOLVED: To improve the balance of a force in converting a vibrating or a reciprocating movement into a rotating movement and to reduce the vibration loss by providing acting elements between an output rotor and an input vibrator and by setting the acting elements each to thrust the output rotor in the opposite direction from each other. SOLUTION: When an input vibrator 2 is connected to a spindle 6 via an elastic body 5 and vibratingly reciprocates in the direction shown by an arrow, clearances 4 formed in the bottom ends of acting elements 3 are disappeared in lowering of the input vibrator 2 so as to be in contact with an output rotor 1. Then, the two acting elements 3 each thrust the output rotor 1 in the opposite directions so as to provide the output rotor 1 with a rotating force about a rotation axis 7. Secondly, when the input vibrator 2 is raised, the output rotor 1 continues to rotate by the inertia, while the input vibrator 2 returns to its original position. The vibration reciprocating movement of the input vibrator 2 is continuously converted into the rotating movement of the output rotor 1 by this repetition. The spindle 6 is fixed to a pedestal 9 and a bearing 8 is composed of a ball bearing, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial application] Motion direction conversion mechanism of industrial equipment

[0002]

2. Description of the Related Art In industrial equipment, there has been a combination of gears in a mechanism for converting a vibrating reciprocating motion into a rotary motion in industrial equipment, but a main mechanism is a crank mechanism as an element.

[0003]

The object of the present invention is to convert a reciprocating motion into a rotary motion as in the case of a crank mechanism. And the vibration loss was a major drawback. It is an object of the present invention to eliminate this and to convert the vertical reciprocating motion into a horizontal rotating motion.

Means for Solving the Problems As means for solving the problems,
A rod-like working body (3) is provided between the output rotating body (1) and the input vibrating body (2), and the two working bodies strike the output rotating body (1) diagonally in opposite directions to twist. Gives a rotational force about the rotation axis (7) to the output rotating body (1).
At this time, the balance and transmission of the force are always symmetric with respect to the rotation axis (7).

[0005]

[Operation] To explain this with reference to FIG. 2, the input vibrator (2) is connected to the main shaft (6) via the elastic body (5), so that the input vibrator (2) is With the reciprocating vibration, when the input vibrating body (2) is lowered, the small gap (4) at the lower end of the working body (3) is eliminated and the output rotating body (1) comes into contact.

At this time, the two rotating bodies (3) push the output rotating body (1) obliquely in opposite directions to each other, so that the twisting force is applied to the output rotating body (1) about the rotation axis (7). And give a turning force.

Next, when the input vibrating body (2) rises, a gap (4) occurs, and the output rotating body (1) continues to rotate due to inertia, but the input vibrating body (2) returns to its original state. .

By this repetition, the reciprocating vibration of the input vibrator (2) is continuously converted into the rotational motion of the output rotor (1).

The output shaft (10) extracts the rotational force of the output rotating body (1) to the outside. The main shaft (6) is fixed to the pedestal (9), and the bearing (8) is a ball bearing or the like.

【Example】

[0010] In order to operate smoothly in the implementation,
Either the working body (3) or the output rotating body (1) needs to be an elastic body such as a leaf spring or a rubber disk.

[0011] In addition, a large number of multiple acting bodies (3) are possible. The rotation speed increases as the position of the action point approaches the rotation axis (7). The further the distance, the slower the rotation speed, but it operates with small input.

The positions or functions of the input vibrating body (2) and the output rotating body (1) can be interchanged. In other words, in this case, the state is protruded from below, and the gap (4) becomes the upper end of the operating body (3). Although universal joints can be used above and below the working body (3) instead of the gap (4), the structure becomes more complicated.

Since the configuration is as described above, the following effects can be obtained.

When converting vibration or reciprocating motion into rotary motion, the flow of force is well-balanced and the vibration loss is small for smoothness.

An unprecedented new element has been obtained in which the output rotation plane is perpendicular to the vibrating reciprocating input line.
