Embodiment 1

[0042] Example 1: When in use, it is set that there are 3 paddle mechanisms installed on the main shaft 2, then there are 3 matching output mechanisms and 3 angle control mechanisms, and the main shaft 2 outputs power, which is driven and installed on the main shaft 2. The components above move, the main shaft 2 passes through the fixed gear 3, and the fixed gear 3 is placed on the engine casing 1, so during the rotation of the main shaft 2, the fixed gear 3 will not rotate accordingly, and the rotating gear 4 meshes with the fixed gear 3, so When the main shaft 2 rotates, the rotating gear 4 makes a circular motion around the fixed gear 3 along with the main shaft 2, and at the same time the rotating gear 4 rotates around the first bearing 6, and the gear ratio of the two is controlled to control the speed of the two. When the rotating speed ratio is 1:1, the angular tooth disc 5 installed in the control angle mechanism uses a double-angle tooth disc, and the outer edge of the...

Embodiment 2

[0044] Embodiment 2: According to Embodiment 1, replace the double-angle tooth disc and the double-arc gear with a single-angle disc and a single-arc gear, and change the wheel ratio between the fixed gear and the rotating gear so that the speed The ratio is 1:2, that is, every time the main shaft 2 rotates 360 degrees, the single-angle tooth disc rotates 720 degrees, and every time the single-angle tooth disc rotates 360 degrees, the single arc gear rotates 360 degrees, and the same effect can also be achieved.

Embodiment 3

[0045] Embodiment 3: On the main shaft 2, and located on one side of the paddle mechanism, add a group of paddle mechanisms with the same structure, and extend the transmission shaft between the angle control mechanism and the paddle mechanism to make it drive and then add The installed paddle mechanism forms a multi-blade coaxial system, increases the number of blades, increases the working area, and increases the work efficiency, and the multiple sets of blade mechanisms are controlled by a set of angle control mechanisms. This mechanism is mainly used for Transformation of natural power such as wind energy.

Abstract

The invention discloses an efficient flat change propeller, which comprises an engine shell and a spindle. The spindle is mounted in the engine shell in an inserted mode, and homologous double-outputmechanisms which are at a certain angle and are symmetrically distributed along the spindle are mounted between the engine shell and the spindle; and angle control mechanisms matched with the homologous double-output mechanisms are mounted on the spindle, and propeller blade mechanisms matched with the spindle are mounted on the positions, on one sides of the angle control mechanisms, on the spindle. The efficient flat change propeller is convenient to use, easy to operate and firm in mounting, and through cooperation of the homologous double-output mechanisms, the angle control mechanisms andthe propeller blade mechanisms on the efficient flat change propeller, the problems that as for an existing propeller, the kinetic energy conversion efficiency is low, and propeller blade variable angle control mechanisms are complex are effectively solved.

Description

technical field [0001] The invention relates to the technical field of power machinery, in particular to a flat variable pitch. Background technique [0002] Most of the existing blades are propellers, and the rotation plane of the propeller is perpendicular to the direction of the driving force. The airflow or water flow is pushed to the direction of the driving force through the spiral structure, and the machine is advanced under the push of the reaction force. [0003] Nowadays, with the improvement of science and technology, changing the rotation angle of the blade and making it work better has become a reality, such as the application of propellers on helicopters, but because the rotation plane of the existing propellers is perpendicular to the direction of the driving force, Therefore, its power conversion efficiency is low, a lot of energy is wasted, and the control mechanism installed is very complicated and the operation is cumbersome if it wants to change the blade...
