Description

The present invention relates to power transmission of a propeller-like drive device for fluid.

Conventionally, a fluid drive device has been developed that devise the shape of a propeller-like wing with respect to a fluid and efficiently and quietly sound (see Patent Document 1).

Conventional propeller-like drive devices for fluids, so-called propellers and screws, transmit power for propulsion to the propeller shaft.

As a result, a device for transmitting power to the central axis of the propeller rotating concentrically is required, and this device itself hinders the flow of fluid.

When a strong power transmission device is installed to obtain a strong driving force, the fluid resistance increases accordingly.

Patent application 2005-50521

  The present invention is to improve the operational efficiency of a propeller-like drive device that scrapes fluid.

A conventional propeller-like drive device includes a power transmission device in a concentric circle of the propeller, and this is a fluid resistance.

When trying to make a small and highly efficient drive device, the transmission device becomes smaller and the performance is not as expected. There was a problem that if the size was increased, the drive device itself would have to be increased.
The present invention solves these problems.

Conventional propeller-like drive devices transmit power to the shaft. This is abolished and power is applied to the outer edge of the propeller. Thereby, it is not necessary to arrange the power transmission device in a concentric circle, and a more efficient drive device is realized.

Embodiments of the present invention will be described with reference to the drawings.

This is an embodiment with claims 1, 2 and 3. This is a propeller-like fluid drive device. It has an outer ring as a feature, and gear teeth are cut in this outer ring. An electric motor and a motor are connected to the outer ring via gears to obtain power.

FIG. 1 shows a front view of this embodiment. S1001 is a propeller-like wing. This uses S1000 as the axis of the propeller.

S1002 is fixedly connected to S1001 in an outer ring shape. And the tooth | gear of the gear cut by S1002 is S1003.

Accordingly, S1003 can be rotated by applying power to S1003 with a gear. The fluid can be scraped by the rotation of S1001.

S1005 is a gear for transmitting power to S1003. Power is transmitted via S1006.

FIG. 2 is a top view of this.
S1101 is a motor. By rotating this motor, S1005 connected in S1104 is rotated, and as a result, S1002 is rotated.

Since S1101, which is a propeller for writing out fluid, is grounded and fixed to S1002, as a result, S1101 rotates.

S1000 is a coaxial for stably fixing S1101. For fixing to a device incorporating the present invention.

If S1003 is fixed with three or more gears, S1000 is unnecessary. Note that S1000 is not an essential device. In this embodiment, S1000 is adopted as a method for stably fixing S1001 without vibration.

  FIG. 3 shows the devices of the first embodiment arranged in parallel. By transmitting power from the outer ring, a plurality of S1007s, which are the main body of the present invention, are arranged in parallel.

In this embodiment, S1007 is directly meshed, but a gear or the like may be inserted therebetween.

FIG. 4 shows the devices of Example 1 arranged in series. The two S1007 share the axis S1000. One or both of the two S1007s are not fixed to S1000. Simple shaft insertion or bearing grounding.

Two rotation directions of S1101 are arbitrary. Both may be in the same direction.
Also, if one side is reversed and the pitch of the pair S1001 is reversed and reversed, a contra-rotating propeller can be obtained and an efficient drive device can be obtained.

In this embodiment, a pair of S1101 is arranged in two S1007. However, this may be arbitrary, and S1101 may be one and a plurality of S1007s may be driven via a gear. In this case, there is an advantage that the apparatus is simplified.

In the first embodiment, the shape of S1007 of S1007 which is the main body of the present invention is devised so that the chain is hung so that S1007 can be driven by the chain.

In Example 1, the shape of S1003 of S1007, which is the main body of the present invention, is removed from the teeth and smoothed so that the belt can be applied so that S1007 can be driven by the belt.

A magnet is arranged on the outer ring portion of S1007, which is the main body of the present invention in Embodiment 1, so that S1007 can be driven by the principle of magnetic force.

Starting from S1007, the outer ring is abolished, and instead, a magnet is placed outside the wing tip of S1001 so that S1007 can be driven by the principle of magnetic force.

The shape of S1007 of S1007 which is the main body of the present invention in Example 1 is devised so that S1007 can be driven by a highly viscous fluid as a fluid joint.

It is a front view of the propeller with an outer ring. It is a top view of a propeller having an outer ring. It is a front view of a propeller having a plurality of outer rings. It is a top view at the time of arranging a plurality of outer ring propellers in series.
