Abstract

PURPOSE:To provide a large force by supporting lightly both ends of a horizontal energy accumulating shaft integral with a flywheel with pivots to block the axial movement thereof and arranging a pair of upper and lower rotary disks respectively on both sides of the flywheel. CONSTITUTION:When a user sits on a saddle 3, holds a handle 5 and alternately depresses left and light pedals 10 with both feet a rotary shaft 6 is rotated through left and right rods 11 and a crank 7. The rotation of the rotary shaft 6 is overdriven and transmitted to an output shaft 12 through a chain wheel 14, chain 15 and sprocket 13 to drive a shaft of a generator or the like through a sprocket 46 and chain 47. While the output shaft 12 is rotated, an energy accumulating shaft 17 is overdriven drivably through a chain wheel 44, chain 45 and sprocket 43 to be rotated with high speed to-gether with a flywheel 35. Since the rotation of the flywheel 35 is reversely transmitted to the output shaft 12, continuous running is enabled only by lightly pedalling the pedals 10.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an input motor whose purpose is to obtain desired rotational power by input.

[Conventional technology]

2. Description of the Related Art A device is known that has a bicycle-style saddle and pedals, and a person sitting on the saddle depresses the pedals to turn the wheel to improve physical strength.

Furthermore, an input motor that rotates a flywheel and extracts energy by utilizing the rotational force has been known for a long time.

[Problem to be solved by the invention]

Conventional devices such as those mentioned above can compensate for lack of exercise,
Although it is possible to improve leg strength indoors, this energy is completely wasted even though it consumes so much energy.

In addition, in conventional devices using a flywheel, the flywheel is large and heavy compared to the energy extracted, and its shaft is also thick, resulting in a large waste of power from the person who steps on the pedal. The problem of this invention is to make the flywheel as small as possible, fix the small flywheel in the center of the energy storage shaft, and use the newly invented ultra-high-speed rotation support means to rotate it at high speed and obtain a large amount of force. By doing so, the input motor as a whole can be made smaller and lighter.

[Means to solve the problem]

In order to solve the above problems, the present invention provides a device that rotates a flywheel at high speed through a transmission means by stepping on a pedal, and rotates an output shaft linked to the flywheel, which is integrated with the flywheel. Both ends of the horizontal energy storage shaft of the flywheel are lightly supported by pivots to the extent that movement in the axial direction is prevented, and a pair of upper and lower rotating disks are arranged on each side of the flywheel, and each rotational disk allows the energy storage to be carried out. The upper and lower parts of the shaft are rotatably supported but not movable in the vertical direction, and furthermore, front and rear rotating discs are arranged on the sides of each of the upper and lower discs, and these rotating discs rotate the front and rear of the energy storage shaft. It is supported so that it can move freely but not in the longitudinal direction, and a plano is provided on the outer periphery of the lower rotating disk that contacts the lower oil reservoir and the energy storage shaft to apply lubricating oil in the oil reservoir to the outer periphery of the energy storage shaft. provides an input prime mover.

[Effect]

The present invention has the above-mentioned configuration, and the user sits on the saddle, holds the handlebars, places the left and right feet on the left and right pedals, and depresses the pedals alternately.

When the left and right pedals are pressed down as described above, the swing lever integrated with the pedals swings up and down, rotating the rotating shaft in a fixed direction via the rod and crank.

When the rotating shaft rotates as described above, the rotation is accelerated by the transmission means and transmitted to the output shaft, and the output shaft drives a generator or the like.

On the other hand, as described above, when the output shaft rotates, that rotation is increased in speed and transmitted to the energy storage shaft, causing the flywheel to rotate at high speed, allowing the output shaft to continue rotating simply by lightly pressing the pedal.

In this action, since the upper and lower and front and rear sides of the energy storage shaft are supported by rotating disks, even if the energy storage shaft rotates at high speed, each of the rotating disks supporting the energy storage shaft rotates at a relatively slow speed.

Moreover, since both ends of the energy storage shaft are simply supported by pivots, there is very little resistance during rotation compared to conventional shafts in which both ends are directly supported by ball bearings. There is also less wear.

Reference numeral 21 denotes a support plate, and this support plate 21 is fixed to the outer ends of a pair of ports 22 fixed to the left and right sides of the portion where the hole 1S is formed on both sides of the machine box 16.

A recess 23 facing the cap 18 is formed in the center of the inner side of both support plates 21, and a flexible rubber plate 24 is applied from inside this recess 23 to around it and fixed by reshaping or the like. The tip of the pivot 25, whose tip is pushed into the center hole, is opposed to the center of the recess 20 at an interval of about 0.5 m as shown in FIG. 7a.

Note that a spring may be used to hold the pivot 25 instead of the illustrated rubber plate 24.

As shown in FIGS. 4 to 6, four shafts 26 of different lengths are fixed to the inner surfaces of both side walls of the machine box 16, surrounding the energy storage shaft 17, and hair is attached to the inner end of each shaft 26. The outer periphery of a rotatably mounted disc 27 is brought into contact with the outer periphery of the power storage shaft 17 above and below and in front and back of the shaft 17 via a ring, thereby supporting the same shaft 17 rotatably.

Each of the rotating disks 27 described above is arranged so that the spacing between the left and right rotating disks 27 that support the upper and lower sides of the energy storage shaft 17 and the spacing between the left and right rotating disks 27 that support the front and rear of the energy storage shaft 17 are equal.

In addition, left and right oil reservoirs 30 with open tops are fixed to the lower part of the machine box 16, and a brush 31 is attached to the outer periphery of the lower disc 27.

40 is a control wire connected to the rear end of the arm 37, and this wire 40 is guided upward as shown in FIGS. 1 and 2 and connected to a brake lever 41 swingably mounted near one end of the handle 5. A spring 42 is attached to the arm 37 to apply a rotational force in a direction to separate the brake shoe 36 from the outer periphery of the flywheel 35.

A small-diameter sprocket 43 is fixed to one end of the energy storage shaft 17, and an endless chain wheel 45 is applied between the sprocket 43 and a chain wheel 44 fixed to one end of the output shaft 12, thereby increasing the rotation speed of the output shaft 12. so that the energy is transmitted to the energy storage shaft 17.

46 is a sprocket fixed to the other end of the output shaft 12;
An endless chino 47 is connected to this sprocket 46 and a sprocket fixed to the shaft of a generator (not shown) to drive the generator or the like from the output shaft 12.

In the above embodiment, the user sits on the saddle 3, holds the handlebar 5, and places both feet on the left and right pedals 10.

When the left and right pedals 10 are pressed down alternately with the left and right feet, the rotating shaft 6 is rotated via the left and right rods 11 and the crank 7.

The rotation of the rotating shaft 6 is transmitted to the output shaft 12 via the Cheno wheel 14, the Cheno wheel 15, and the sprocket 13 at increased speed.
Departs via sprocket 46 and chenno 47! Drives the shaft of the nato.

On the other hand, when the output shaft 12 rotates as described above, the accumulating shaft 17 is accelerated and driven via the Cheno wheel 44, the Cheno wheel 45, and the sprocket 43, and rotates at high speed together with the flywheel 35.

Since the rotation of the flywheel 35 is reversely transmitted to the output shaft 12, continuous operation is possible by simply pressing the pedal 10 lightly.

When stopping the operation in an emergency, the wire 40 is pulled by stopping the depression of the pedal 10 and simultaneously turning the brake lever 41 in the direction of the handle 5, causing the arm 37 to rotate in the direction of the arrow in FIG. is pressed against the outer periphery of the flywheel 35 to perform braking.

In the above operation, the caps 18 at both ends of the energy storage shaft 17
Since the cap 18 is detachable and supported by the pivot 25, when the cap 18 wears out, only the cap 18 needs to be replaced with a new one, and the shaft 17 does not need to be replaced.

In addition, both ends of the shaft 17 are supported by pivots 25, and the outer periphery of the shaft 17 is supported by a plurality of rotating disks 27, so that the energy storage shaft 1
The frictional resistance of the support mechanism 7 is extremely small.

Further, the brush 31 on the outer periphery of the lower disc 27 is coated with lubricating oil 32.
By applying the same oil to the outer periphery of the accumulating shaft 17, the frictional resistance between the disc 27 and the shaft 17 is further reduced.

Therefore, the flywheel 35 can rotate at high speed with an extremely small driving force, generate a large inertial force, and assist the rotation of the output shaft 12.

In addition, when running a generator, it is recommended to connect the output circuit of this generator to the input circuit of a battery and store the remaining power.

In the above embodiment, the input motor is provided on the base 1, but
When installing this input prime mover directly on the work machine, base 1
is no longer necessary. Further, in that case, although the positions and directions of each rotating shaft and pedal may change, the order of force transmission does not change.

[Effects of the Invention] As described above, this invention rotates the output shaft by input to rotate a generator, a water intake device for irrigation, etc., so it is suitable as a power source in remote areas where there are no electric light lines. There is.

In addition, it can be loaded onto a camping car and transported, and used to generate electricity without consuming valuable fuel such as gasoline, or to be used as a power source for various other devices, such as a gasoline engine. There is no risk of environmental pollution due to exhaust gas.

In particular, in this invention, both ends of a horizontal power storage shaft that is integrated with the flywheel are lightly supported by pivots to the extent that movement in the axial direction is prevented, and a pair of upper and lower rotating disks are arranged on each side of the flywheel. The upper and lower sides of the energy storage shaft are rotatably supported by these rotary disks, but cannot be moved in the vertical direction, and front and rear rotary disks are arranged on the sides of each of the upper and lower disks to support each rotational disk. Since the energy storage shaft is rotatably supported in the front and rear directions by the plate, but cannot be moved in the front and back directions, the following effects can be obtained.

That is, since conventional rotating shafts are supported at both ends by small-diameter hair rings, the balls and rollers rotate within a small-diameter circumference, which creates a large amount of resistance when the shaft rotates at extremely high speeds.

In contrast to the conventional bearing means as described above, the present invention has a structure in which the energy storage shaft rotates while being held from all sides by the circumference of four discs on each side, so there is almost no resistance during rotation. It is possible to perform light (ultra high speed rotation).

In addition, a brush is installed on the outer periphery of the lower rotating disk to constantly lubricate the energy storage shaft by contacting the lower oil reservoir and the energy storage shaft and applying lubricating oil in the oil reservoir to the outer periphery of the energy storage shaft. By applying oil, the resistance is further reduced, and since the left and right movement of the storage shaft is only regulated by the tip of the pivot and no other support means are used, the area that generates frictional resistance is significantly reduced. There are effects such as
