Definitions

• the present invention relates to a vertical axis wind turbine with a set of thirty-two blades distributed along the axis in groups of four, thus forming eight levels.
• the drawings accompanying and integrating this report show: Figure one: perspective view of the turbine with only one set of blades, the others are identical only from one set to another and the blades are interspersed for better energy absorption from the winds.
• FIG. 1 shows a front view of the vertical axis (1) where we clearly see the positions of the interleaved blades and also in relation to the wind direction line.
• Blades "A” belong to one level and 45 ° offset from blades "B” that belong to the near level for better distribution of wind strength on the vertical axis.
• the blades "C” have their faces in the horizontal position cutting and turning against the winds.
• the blades "D” have their faces in an upright position receiving the impact and turning in favor of the winds.
• Figure 2 also shows the direction of rotation (19); The arrow indicating the direction of the winds (18); The swing limit pins (20) of the paddle shaft (17) and vertical shaft (1).
• Figure 3 shows the lower (5) and upper ( 1 ) sections in cuts, the turning limiting pins (20) of the blades and their fixation on the blades axes (17) and the vertical axis (1).
• the lower bearing consists of a support (21) with cap (22), a ball (23), ball lock pin (24) and two bearings (25).
• the locking pin prevents the ball only rotate, but allows an axial movement of the to 5, thereby preventing the bearing effort as the vertical axis scale suffers due to its long length and wind pressure on the blades.
• the upper bearing (6) has the same operation as the lower bearing, but without bearings. In the drawing we see the bracket (26) with the hooks (30) where will be the steel cables (3); Ball lock pin (27) and ball axis (29).
• the swing limit pins (20) of the blades should have a rubber
