BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kind of multifunctional power saving type transmission mechanism, and mainly relates to any device driven by an electric motor,
For example, the present invention relates to a transmission mechanism that can be used for home appliances such as fans, refrigerators, coolers, and washing machines, as well as transportation tools such as electric vehicles and motorcycles.

[0002]

2. Description of the Related Art Traditional electric home appliances such as fans, washing machines, refrigerators, coolers, etc. are driven by electric motors, and electric vehicles and motorcycles are all driven by highly efficient, high torque electric motors. The working voltage and working current of these electric motors are all very high, which causes high temperature during operation,
Problems such as noise and consumption of electric energy occurred.

The current and voltage required by a general small electric motor are very small. However, the output torque is not relatively large. For this reason, it has not been possible to drive these large electric appliances, electric cars and motorcycles using these small electric power saving electric motors.

Further, conventionally, the conventional transmission mechanism has to be designed by changing the combination of gears according to different working conditions, and thereby a certain amount of output torque has been obtained. For this reason, one particular transmission mechanism can usually only be used for one device.

[0005]

The problem to be solved by the present invention is, first of all, that the number of reduction gear units according to the present invention can be arbitrarily increased or decreased in accordance with actual demand, whereby the required output torque is reduced. It is an object of the present invention to provide a multifunctional power saving type transmission mechanism.

A second object of the present invention is to provide each of the reduction gears of the present invention with a large number of drive auxiliary shafts which mesh with the main shaft thereof, and the drive auxiliary shafts can be arbitrarily removed and the number thereof is required. It can be changed at will.

A third object of the present invention is to provide the drive sub-shaft with two
One gear is provided, and the number of teeth and the diameter of these gears can be arbitrarily changed according to demand.

A fourth object of the present invention is to make it possible to mutually adjust the numbers of the reduction gear device and the high-speed compact combined electric motor in the present invention, and thus to make this mechanism adaptable to different working situations. That is.

A fifth object of the present invention is to make it possible to effectively increase the output horsepower by providing one or more sets of high-speed compact combination electric motors in the present invention and connecting them by a connecting device. is there.

A sixth object of the present invention is that the fixed seat of the gear in the present invention can be integrally molded by injection molding, and a reduction gear device, an output gear device and a combination electric motor can be attached to the fixed seat. The purpose of the present invention is to assemble the present invention quickly.

A seventh object of the present invention is to make the shape of the fixed seat by injection molding different so that it can meet the demands of different works.

[0012]

The present device mainly comprises at least one combination electric motor composed of a high-speed and electric power saving type small electric motor, and further, a reduction gear device and an output gear device.

Among them, the reduction gear device is provided in one set or in combination of a plurality of sets, thereby adapting to the demands of different jobs.

Further, since the electric motor has a characteristic of high speed and low torque, many small electric motors may be combined into one combined electric motor in order to increase the torque.

Furthermore, in order to obtain a large output horsepower, the combined electric motors may be connected by an arbitrary number of connecting devices and used for driving. The combination motor can directly drive several sets of reduction gears according to the demand of work.

Each of the reduction gear units has one fixed seat, and the main shaft of the gear unit is attached to the center of the fixed seat. First and second gears are attached to both ends of these main shafts, and a large number of mounting holes are symmetrically arranged around the main shaft in the fixed seat. Some of the holes can be selected according to the working conditions, and a plurality of counter shafts that mesh with the main shaft can be attached thereto, thus achieving the most ideal operating condition.

Two gears having the same or different number of teeth and different diameters, that is, first and second gears can be attached to one end of the counter shaft.

Further, the output gear device can output power to drive the driven device.

[0019]

The efficiency of consumption of the conventional electric motor and the combination of the small electric motor and the reduction gear device of the present invention under the same working conditions are compared below: The torque calculation formulas of general AC and DC electric motors are as follows. It is shown in Equation 1.

[Equation 1] T: Torque N: Revolutions per minute HP: Horsepower

AC 220V 1HP and AC 22
Taking an electric motor of 0V 3HP 3600 rotation as an example, the rotation speed is fast, but the output torque is relatively small. If the rotation speed is slowed, the output torque increases. However, the consumption efficiency is 746 W / H and 2238 in any case.
W / H.

Taking a small electric motor using DC12V, full load 25g, current consumption 560mA, and rotation speed 13340, the same rotation speed as in the above example can be obtained by using the reduction gear device, and different numbers are used. The combination of a small electric motor and different reduction gearboxes of the above achieves the required maximum efficiency. That is, it was found that the consumption efficiency was less than 1/11 of the consumption efficiency of the above-described traditional electric motor. This can save a large amount of electric energy.
