This hybrid pulley assembly is comprised of two outer driven synchronized timing pulleys and a centerpiece inner driver timing pulley. This pulley assembly operates in such a manner where the input driving timing belt mounted on the centerpiece timing pulley positively drives the outer synchronized timing pulleys. An outer driven timing belt, which is mounted on the outer driven timing pulleys and across the centerpiece driver timing belt, is partially supported by the centerpiece driver timing belt top surface in the area enclosed by the two outer synchronized timing pulleys. This configuration allows this hybrid pulley assembly to be driven from within. This alleviates the need of conventional drive train systems where a timing driven belt is driven through an axial input to the driven timing pulley.

The invention is a timing belt transmission automatic wind opposing deviation device of a wind power generator. A power generator (15) is connected with a revolving body (engine cabin) (18). The revolving body shaft (17) is connected with a pole (16). The shaft (17) is provided with a carbon brush (2), a carbon brush (3) and a large synchronous belt pulley (4).

Thus, the revolving body can drive the small synchronous belt pulley (6) to rotate circumferentially around the large synchronous belt pulley (4) on the revolving body shaft (17) via a timing belt (5). The carbon brush (2) is responsible to input the externally stored electric current into the stepped electric motor (11), while the carbon brush (3) is responsible to output the power generated by the generator (15). The advantage of the wind deviation device is that when the wind power generator is working, the device can oppose the wind automatically and deviates from the wind in the case of a strong wind, so as to reach the purpose of automatic speed controlling and limiting and achieve the self-protection function of the wind power generator. The device avoids large tail fins of a wind power generator in the past. With the device, a wind power generator can be controlled and operated intelligently, is more reliable in the work, and is free of maintenance for a long time.
