Abstract

PURPOSE: A rotational force generator using a mechanical spring is provided to cut down producing costs by simplifying the structure for limiting the rotational force of an input shaft to a main gear and to promote convenience in use by indicating time available for rotational force. CONSTITUTION: A clutch plate(14) is fixed to an input shaft(5) near a main gear(7'). The main gear is connected in an axial direction of the input shaft slidably and designed to apply elasticity toward the clutch plate by a spring(S). A locking protrusion(114) is formed on a side of the clutch plate opposed to the main gear, having a locking surface and a sliding surface. Another locking protrusion(17) is formed on a side of the main gear with a locking surface and a sliding surface. The two protrusions rotate the input shaft by an external force to wind a mechanical spring(6). The rotational force of the clutch plate by the input shaft is not transferred to the main gear. If the external force is removed from the input shaft, the locking protrusions are locked each other by elastic rotational force of the mechanical spring. Thereby, the rotational force of the mechanical spring is transferred to the main gear. The rotational force is generated through an output shaft(10a) for a long time if the external force is removed after rotation of the input shaft.

Apparatus for generating rotative force using spring}

The present invention relates to a rotational force generating device using a mainspring for generating a rotational force by using the mainspring, and more particularly, a rotational force using the mainspring which is simple in configuration and instructs the generation time of the rotational force to facilitate the use. It relates to a generator.

Representative examples of the motor may include a motor, a prime mover, and the like. The means for generating torque is applied to various fields of the industry.

However, in order to operate the rotational force generating means as described above, electricity or a liquid or solid fuel is required, and thus use in a situation where supply of electricity or fuel is difficult is limited.

As a representative for solving the problems of the rotational force generating means as described above is provided a rotational force generating device using a spring, the configuration is as follows.

9 is a cross-sectional view for explaining a rotational force generation process of the conventional rotational force generating apparatus 100 using a spring, Figure 10 is a perspective view seen from the C-C line direction in Figure 9, respectively.

Reference numerals 101, 102, and 103 are first, second, and third plates fixed by a plurality of fasteners 104 so as to maintain a predetermined distance in parallel, respectively.

Input shafts 105 passing through the first, second, and third partitions 101, 102, and 103 are rotatably coupled, and one end portion of the input shaft 105 protrudes outwardly of the first plate 101 and protrudes. At the distal end portion of the 105, a rotary ball engaging portion 105a formed in a flat surface is formed.

On the outer circumference of the input shaft 105 between the first plate 101 and the second plate 102, a spiral spring 106 wound in a spiral shape is disposed. And the inner end of the mainspring 106 is fixed to the outer periphery of the input shaft 105, the outer end of the mainspring 106 is any one fastener fixing the first plate 101 and the second plate 102 It is caught by 104 and fixed.

The main gear 107 is slidably coupled to the input shaft 105 between the second plate 102 and the third plate 103, and the ratchet wheel 108 is fixed to the side of the main gear 107.

In addition, the rotation plate 109 is fixed to the input shaft 105 of the position close to the ratchet wheel 108, and the outer end portion of the stop plate 110 is fixed to the rotation plate 109, and the inner end portion of the stop plate 110 is fixed. Is elastically inserted into the valley portion between teeth in the ratchet wheel 108.

In the above configuration, in the state in which the input shaft 105 is rotated in the counterclockwise direction (left direction), the inner end portion of the stopping plate 110 slides at the teeth of the ratchet wheel 108 so that the rotational force of the input shaft 105 is driven. When the input shaft 105 is rotated in the clockwise direction and is not transmitted to the gear 107, the inner end of the ratchet wheel 108 is locked to the valley of the ratchet wheel 108 so that the rotational force of the input shaft 105 is driven. It is intended to be transmitted to the gear 107.

The rotational force of the main gear 107 is configured to be doubled by the first and second double gears 111 and 112, and the doubled rotational force is output through the output shaft 112a which rotatably fixes the second double gear 100. The rotation speed of the output shaft 112a is maintained by the rotation speed control means 113.

The rotational speed control means 113 includes a double speed gear 113a engaged with the second double speed gear 112, a ratchet wheel 113b rotated by the double speed gear 113a, a ratchet wheel 113b, A pendulum plate 113c rotatably installed at an adjacent position, and a pair of jersey pins 113d fixed to the pendulum plate 113c and sequentially inserted into the valley portion of the ratchet wheel 113b.

The rotation speed control means 113 is a portion of the valley of the ratchet wheel 113b while the pair of jersey pins 113d slide along the tooth surface of the ratchet wheel 113b which rotates together with the output shaft 112a. The rotational speed of the output shaft 112a is controlled constantly by the action of being repeatedly inserted sequentially.

In order to generate the rotational force by using the conventional rotational force generating device as described above, first, the input shaft 105 in a state in which a rotating sphere (not shown) is coupled to the rotating sphere coupling portion 105a of the input shaft 105. Rotate counterclockwise.

In the state in which the input shaft 105 is rotated as described above, since the inner end portion of the stopping plate 110 slides in the teeth of the ratchet wheel 108, the rotational force of the input shaft 110 is not transmitted to the main gear 107. Due to the rotation of the input shaft 105, the spring spring 106 is wound toward the input shaft 105, the elastic rotational force is accumulated.

Here, when no external force is applied to the input shaft 105 during the process of rotating the input shaft 105, the inner end portion of the stop plate 110 is locked to the teeth of the ratchet wheel 108, so that the input shaft 105 is spring-loaded. There is no fear of the reverse rotation rapidly due to the elastic force of the 106.

As described above, after rotating the input shaft 105 by a certain number of revolutions using the rotary ball, and removing external force from the input shaft 105, the elastic rotational force accumulated in the spring spring 106 and the inner distal end of the stopper plate 110 Due to the locked state of the tooth wheel 108, the input shaft 105 rotates in the opposite direction with the main gear 107 in the opposite direction from the front, and the rotational force of the main gear 107 moves the first and second speed gears 111 and 112. It is assigned during transmission and generates a rotational force through the output shaft 112a.

Therefore, the rotational force generating device 100 using the springs as described above is widely used in a device requiring rotational force because it can generate rotational force for a considerable time in a situation where supply of fuel or electricity is difficult.

However, in the rotational force generating device 100 using the spring as described above, in order to intermittently rotate the rotational force of the input shaft 105 to the main gear 107, the ratchet wheel 108 rotating plate 109, the stop plate ( 110) and so on, and the configuration is not extremely simple, and since the possible time of rotational force is unknown, there is inconvenience in use.

SUMMARY OF THE INVENTION The present invention has been invented in view of the above-described conventional problems, and its object is to make the production cost of the entire apparatus low and inexpensive by extremely simple configuration for controlling the rotational force of the input shaft to the main gear. It is an object of the present invention to provide a rotational force generating device using a spring which can be supplied to the electric field and can indicate the possible time for the rotational force to greatly increase the ease of use.
