Description

Step-up gear for minimum of talk reduction.

The present invention relates to a speed increase gear device that minimizes torque reduction. More particularly, at least one speed reduction gear is engaged with both sides of the speed increase gear to minimize torque reduction by a plurality of gears in which a speed increase gear and a reduction gear are coupled to each other. The present invention relates to a speed increase gear device.

A gear is a device that transmits rotation or power between two or more axes and serves to increase or decrease the number of revolutions by using an appropriate gear ratio.

In general, the gearbox is a device that increases the rotational speed by biting a large gear on the drive shaft and a small gear on the driven shaft to reduce the torque in inverse proportion to the gear ratio.

On the contrary, the reduction gear is a device that reduces the rotational speed by biting small gears on the drive shaft and biting large gears on the driven shaft, and the torque increases in inverse proportion to the gear ratio.

The change in torque depends on the gear ratio because the force of the drive shaft is distributed or concentrated by the gear ratio, which also affects the force input to the drive shaft.

In other words, in the case of the reduction gear which is held in the order of small gear and the large gear, the driving force of the drive shaft may be small, and in the case of the increase gear which is held in the order of the small gear and the large gear, the driving force of the driving shaft should be large.

This can be quickly seen when driving a bicycle with gears. The gears attached to the pedals are less powerful than the gears attached to the rear wheels. In larger gears, the pedaling force is quite significant.

Therefore, low gear is used on the uphill road that is heavy, and high gear is used on the downhill road, where the power is not high.

As discussed above, the speed increase gear serves to increase the number of revolutions by using an appropriate gear ratio, but the energy input to the drive shaft increases, and the force or torque output to the driven shaft decreases.

The present invention relates to a structure of a speed increase gear that reduces energy input to a drive shaft while reducing the force output to a driven shaft.

Therefore, the present invention has been proposed in view of the problems of the prior art as described above, and an object of the present invention is to combine at least one reduction gear with both sides of the speed increase gear to increase RPM output to the driven shaft while increasing the RPM output to the driven shaft. It is to minimize the reduction of torque by the reduction gears coupled to the.

The present invention has been made in order to achieve the above object, the configuration of the means for solving the problem is as follows.

A drive shaft gear 100 coupled to the drive shaft; A double gear type first dual gear 200 coupled to the other side of the drive shaft gear by a first shaft 900; A first speed increase gear 1000 having a diameter smaller than that of the first double gear, and having one side engaged with the first double gear; A second double gear 210 having the same diameter as the first double gear and engaged with the other side of the first speed gear; A third double gear type 220 having a double gear type coupled to the other side of the first speed increase gear 1000 by a second shaft 910; A second speed increase gear 2000 having a smaller diameter than the third double gear and having one side engaged with the third double gear; A fourth double gear 230 having the same diameter as the third double gear and engaged with the other side of the second speed increase gear 230; A fifth double gear 240 of a double gear type coupled to the other side of the second speed increase gear 2000 by a third shaft 920; A third speed reduction gear 3000 having a diameter smaller than that of the fifth double gear and in which one side is engaged with the fifth double gear; A sixth double gear 250 having the same diameter as the fifth double gear and engaged with the other side of the third speed increase gear; And a double gear type driven shaft gear 4000 coupled to the other side of the third speed increase gear 3000 by the fourth shaft 930.

An increase gear device for minimizing the torque reduction according to the present invention having the above configuration and action,

Combining at least one reduction gear with both gears on both sides increases the RPM output to the driven shaft while minimizing torque reduction by the reduction gears coupled to both gears. .

In other words, if the RPM is increased by only increasing gear to the drive shaft, the RPM increases but the torque decreases, and the force to turn the drive shaft is large. However, in the present invention, the gear and the reduction gear are coupled to both sides of the drive shaft gear at the same time. Therefore, the torque decrease due to the speed increasing gear and the torque increase due to the reduction gear occur at the same time so that the force for turning the drive shaft does not increase.

At this time, depending on the gear ratio of the speed increase gear and the reduction gear coupled to both sides of the drive shaft, the power to turn the drive shaft is increased or decreased. For example, if the gear ratio of the speed increase gear and the reduction gear is the same, the magnitude of the torque increase and torque decrease is the same. Therefore, the force to turn the drive shaft is unchanged, but if the gear ratio is greater than the reduction gear ratio, the power to turn the drive shaft is increased, and conversely, if the gear ratio is greater than the gear ratio, the power to turn the drive shaft is reduced.

In the present invention, the torque reduction is minimized by simultaneously combining one or more reduction gears on both sides of the speed increase gear, respectively, and as the number of reduction gears coupled to both sides of the speed increase gear increases, the torque reduction width decreases.

Therefore, although the number of reduction gears coupled to both sides of the speed increasing gear is configured by two to three in the representative drawings of the present invention, the number of reduction gears may vary from one to a plurality in accordance with the purpose of the gear and the size of the gear. It is possible to configure the combination of the pairs in multiple stages to provide an effect of further increasing the gear ratio while minimizing torque reduction.
