The present invention relates to a rotational force generating device using a mainspring for generating a rotational force by using a mainspring, and more particularly, to a rotational force generating device using a mainspring with a simple configuration and improved ease of use.

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 generating process of the conventional rotational force generating apparatus 100 using a spring, and FIG. 10 is a perspective view seen from the A-A line in FIG.

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 rotational power 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, the ratchet wheel 108, the rotating plate 109, the stopping plate in order to intermittently rotate the rotational force of the input shaft 105 to the main gear 107. Since it is taking various configurations such as (110), the configuration is not extremely simple, and the possible time of rotational force is unknown and it is inconvenient in use because it cannot stop during operation.

The present invention has been invented in view of the above-mentioned conventional problems, and its object is to make the production cost of the whole apparatus low by making the configuration for clamping down the rotational force of the input shaft and the spring spring toward the output shaft extremely simple. It is an object of the present invention to provide a rotational force generating device using a spring that can be supplied at low cost and can indicate the possible time of rotational force and can be stopped during operation to greatly increase the ease of use.

Reference numerals 1, 2, and 3 are first, second, and third plates fixed by a plurality of fasteners 4 so as to maintain a predetermined distance in parallel, respectively, and these first, second, third plates (1, 2, 3). Are housed in the case (C).

The input shaft 5 is rotatably coupled through the first, second, and third partitions 1, 2, and 3, and one longitudinal end portion of the input shaft 5 protrudes outward of the first plate 1. The small gear 5a is coupled to the input shaft 5 between the first, second, and third partitions 1, 2, and 3.

Reference sign H is a rotational handle coupled to the tip of the input shaft 5 protruding out of the case C to facilitate the rotation of the input shaft 5.

The main gear 6 is rotatably installed by the main gear shaft 6a between the second and third partitions 2 and 3, and the main gear shaft 6a is the outer side of the third partition 3. The main gear 6 is engaged with the small gear 5a.

On the outer circumference of the main gear shaft 6a protruding to the outside of the third partition 3, a spiral spring 7 wound in a spiral shape is arranged. The inner leading end of the mainspring 7 is fixed to the outer circumference of the main gear shaft 6a, and the outer leading end of the main spring 7 is fixed to the inside of the case C.

When the input shaft 5 is rotated in the direction in which the spring spring 7 is wound by the above configuration, the small gear 5a, the main gear 6, and the spring spring coupled with the rotational force are coupled to the input shaft 5 ( 7) When the elastic rotational force is accumulated in the spring spring (7) and the external force is removed from the input shaft (5), the main gear (6) and the input shaft (5) in the reverse direction from the front by the elastic rotational force of the spring spring (7) It is supposed to rotate.

In the position where the main gear 6 is kept at a predetermined distance, the first gear 8 made of the small gear 8a and the standby gear 8b is connected to the second, third, and plate 2 by the gear shaft 8c. It is rotatably installed between and 3). At the position close to the first gear 8, a second gear 9 of the small gear 9a and the standby gear 9b is disposed between the second and third plates 2 and 3 by the output shaft 9c. It is installed so that rotation is possible. Here, the output shaft 9c of the second double speed gear 9 protrudes outward of the third plate 3, and the small gear 9a of the second double speed gear 9 is a standby gear of the first double speed gear 8. It is engaged with (8b).

Between the main gear 6 and the 1st speed gear 8, the power control gear 10 which consists of the small gear 10a and the standby gear 10b is rotatably provided by the gear shaft 10c. Wherein the gear shaft 10c is to be moved up and down along the arc-shaped guide groove (G) formed between the second, third plate (2, 3) and to receive an elastic force downward by the spring (S). The small gear 10a is meshed with the main gear 6 and the standby gear 10b is meshed with the small gear 8a of the first double gear 8. Here, the spring (S) is preferably to have an elastic force enough to resist the weight of the power control gear (10). As such, specifying the elastic force of the spring (S) is the power control gear 10 is slid in the guide groove (G) by its own weight when the rotational force generating device using the spring according to the present invention is inclined or upside down This is to prevent the meshing into the single speed gear 8 from becoming impossible.

In the above configuration, when the input shaft 5 is rotated so that the spring spring 6 is wound by an external force, as shown in FIG. 4, the gear shaft of the power control gear 10 is driven by the rotation moment of the main gear 6. 10c) is made to rise in the guide groove G. As shown in FIG. In this state, the small gear 10a of the power control gear 10 rotates while being engaged with the main gear 6, but the standby gear 10b is slid from the small gear 8a of the first double gear 8. By doing so, the rotational force of the input shaft 5 is transmitted only to the spring spring 7 and is not transmitted to the output shaft 9c.

In addition, when the external force is removed from the input shaft 5, as shown in FIG. 5, the gear shaft of the power interruption gear 10 is driven by the reverse rotation moment of the main gear 6 rotating by the elastic rotational force of the spring spring 7. 10c) is to descend in the guide groove (G). In this state, the small gear 10a of the power interruption gear 10 is rotated while being engaged with the main gear 6 and the standby gear 10b is engaged with the small gear 8a of the first double gear 8. As a result, the rotational force of the spring 7 is transmitted to the output shaft 9c through the main gear 6, the power control gear 10, and the first and second gears 8 and 9.

On the other hand, even if the rotational force generating device according to the present invention is inclined or inverted in the state in which the elastic rotational force of the elastic spring S is transmitted to the gear shaft 9c, the power is interrupted by the elastic force of the spring S. The gear shaft 10c of the gear 10 maintains the state of being moved toward the first gear 8 in the guide groove G so that the rotational force transmission to the gear shaft 10c through the power interruption gear 10 may be performed. No problem occurs.

The rotational speed of the output shaft 9c by the spring spring 7 is maintained by the rotational speed control means 11.

The rotation speed control means 11 includes a double speed gear 11a meshed with the second double speed gear 9, as shown in FIGS. 5 and 6, a ratchet wheel 11b rotated by the double speed gear 11a, The pendulum plate 11c rotatably installed on the upper portion of the ratchet wheel 11b and the lower portion of the pendulum plate 11c are integrally formed toward the ratchet wheel 11b and sequentially repeated in the valley portion of the ratchet wheel 11b. And a pair of blocking protrusions 11d inserted into each other.

The rotational speed control means 11 is a portion of the valley of the ratchet wheel 11b while the pair of stopping projections 11d slide along the tooth surface of the letch wheel 11b which rotates together with the output shaft 9c. The rotational speed of the output shaft 9c is constantly controlled by the action of being repeatedly inserted sequentially.

The rotatable time of the output shaft 10a is indicated by the actuation time indicating means 12.

The actuation time indicating means 12 is engaged with the small gears 5a between the first and second partitions 1 and 2 as shown in Figs. 2 and 3 to decelerate the rotational speeds of the first, second and third decelerations. The indicator needle 12d disposed in front of the case C so as to rotate together with the gears 12a, 12b, and 12c, the third reduction gear 12c, and the time indicating the time around the surface of the indicator needle 12d. The dial 12e is fixed to indicate the time.

When the input shaft 5 is rotated by this configuration, the rotation of the input shaft 5 is decelerated through the first, second, and third reduction gears 12a, 12b, and 12c to be transmitted to the indicator needle 12d, and the indicator needle 12d. Denotes the time of the dial 12e in which the output shaft 9c can rotate.

The output shaft 9c can be stopped by the operation stop means 13 during the rotation operation.

As shown in FIGS. 2 and 6, the operation stop means 13 includes a rotation shaft 13a rotatably installed on the second and third plates 2, 3 on the pendulum plate 11c, and the rotation shaft 13a. The pressing blade 13b formed so as to protrude along the longitudinal direction of (), and the adjustment knob 13c fixed to the front-end | tip part of the rotating shaft 13a which protruded toward the front of case (C).

By the configuration of the operation stop means 13, the pressing blade 13b rotates the adjustment knob 13c so as to press the one end of the pendulum plate 11c, so that one stop block 11d of the latch wheel 11b is rotated. The rotation operation of the output shaft 9c can be stopped by maintaining the state inserted in the valley portion. In other words, the rotational motion of the output shaft 9c is stopped by stopping the operation of the rotational speed control means 11 that constantly controls the rotational speed of the output shaft 9c.

The rotation operation of the output shaft 9c is stopped by the zero setting means 14 at the position where the indicator needle 12d of the operable time indicating means 12 indicates the zero point of the dial 12e.

The zero setting means 14 is formed on the outer circumference of the circular plate body 14a and the circular plate body 14a which are integrally formed on the back side of the third reduction gear 12c in the operable time indicating means 12 as shown in FIG. The formed actuation start protrusion 14b and the middle part in the longitudinal direction are rotatably installed, and one end portion in the longitudinal direction is positioned above the pendulum plate 11c, and the other end in the longitudinal direction is formed on the circular plate body 14a. The operation section 14c is elastically in contact with the outer circumferential surface.

By the configuration of the zero setting means 14, the position where the indicator needle 12d indicates the zero point of the dial 12e, that is, the elastic rotational force of the spring spring 7 disappears and cannot reach the output shaft 9c. When it reaches to, the one end part of the operation period 14c is raised by the operation start protrusion 14b. In addition, the other end of the operation shaft 14c presses the other front end of the pendulum plate 11c so that the other stopping protrusion 11d is inserted into the valley of the ratchet wheel 11b to maintain the state of the output shaft 9c. The rotation operation is stopped.

When the rotational force generating device RD using the mainspring of the present invention is generated as described above, the input shaft 5 is rotated in a direction in which the mainspring 7 is wound.

In the state in which the input shaft 5 is rotated as described above, since the standby gear 10b of the power control gear 10 slides in the small gear 8a of the first double gear 8, the rotational force of the input shaft 5 is As it is transmitted to the spring spring 7 through the main gear 6 and the main gear shaft 6a without being transmitted to the output shaft 9c, the spring spring 6 is wound toward the input shaft 5, whereby the elastic rotational power is accumulated.

At this time, when no external force is applied to the input shaft 5 during the process of rotating the input shaft 5, the elastic rotational force accumulated in the spring spring 7 is transferred to the output shaft 9c, so that the input shaft 5 is the spring spring ( There is no fear of reverse rotation rapidly due to the elastic force in 7).

If the external force is removed from the input shaft 5 after the elastic force is accumulated in the spring 7 as described above, the main gear 6 and the input shaft 5 are opposite to each other by the elastic rotational force accumulated in the spring 7. While rotating in reverse, the rotational force of the main gear 6 is doubled while being driven through the power control gear 10 and the first and second speed gears 8 and 9 to generate a rotational force through the output shaft 9c.

In the above operation, the rotatable time of the output shaft 9c is confirmed by looking at the time of the dial 12e indicated by the indicator needle 12d, and the elastic force of the spring spring 7 is extinguished so that the indicator needle 12d is turned on. When the zero point of the dial 12e is instructed, the rotation operation of the output shaft 9c is stopped by the operation of the zero point indicating means 14.

On the other hand, when it is desired to stop the operation during the rotation operation of the output shaft (9c) as described above to stop the operation of the output shaft (9c) by rotating the control knob (13c) of the operation stop means (13).

The present invention as described above can be applied to the non-powered rotary winding machine (R) used outdoors, for example, as shown in FIG.

That is, the rotational force generating device RD using the mainspring of the present invention is installed on the side of the rotary winding machine R, and the output gear 9d is fixed to the output shaft 9c, and the output gear 9d is attached to the outer peripheral surface. When it engages with the rotating plate R1 of the rotary winding machine R in which (iii) was formed, it can rotate the rotating plate R1 of the rotary rolling machine R for a considerable time.

Therefore, while rotating the food by the rotational force generating device (RD) using the spring of the present invention in a state of fixing the food to be baked on the barbecue bar (R2) of the rotary roaster (R) provided with the present invention, the rotary roaster (R) If you fire at the bottom of the whole food is rotated in the cavity is baked evenly.

The rotational force generating device using the mainspring of the present invention is to control the rotational force of the input shaft to the double speed gear by the power interruption gear, and to check the rotatable time of the output shaft by the operating time indicating means and to operate during the rotation operation of the output shaft. It is to be able to stop the operation by the stop means. In addition, the zero setting means stops the rotation operation of the output shaft precisely in the state where the operation time is zero.

Therefore, the present invention is to control the rotational force only by the power interruption gear, it is possible to supply the rotational force generating device using the mainspring at low cost by reducing the production cost according to the simplified configuration. In addition, it is possible to check the possible time of the rotational force, to stop the operation during the generation of the rotational force, even if the device is inclined state, there is no problem in the generation of the rotational force can greatly increase the ease of use. .
