Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, a wind turbine windmill shaft not prone to fracture comprises a metal outer ring 1, a first screw 2 is connected to the surface of the metal outer ring 1 through threads, a spring 3 is fixedly connected to the inside of the metal outer ring 1, rubber rings 4 are fixedly connected to two sides of the spring 3, a middle metal ring 5 is fixedly connected to the bottom of the spring 3, a second screw 6 is connected to the surface of the middle metal ring 5 through threads, a metal plate 7 is connected to the outer portion of the second screw 6 through threads, the metal plate 7 is mainly made of metal foil, is a metal composite material with high ductility and prevents the metal plate 7 from fracturing, the first screw 2 and the second screw 6 are fixedly connected to the metal plate 7, the number of the first screw and the second screw is not less than four, a metal ball 8 is movably connected to the inside of the middle metal ring 5, a metal inner ring 9 is movably connected to the surface of the metal ball 8, the effect of reducing rotational friction has been played, the inside fixedly connected with metal tooth 10 of metal inner ring 9, the surperficial swing joint of metal tooth 10 has dwang 11, the fixed surface of dwang 11 is connected with metal tooth two 12, metal tooth two 10 and metal tooth 12 joint, fixed orifices 13 have been seted up on 1 internal surface of metal outer loop, four are no less than to the number of fixed orifices 13, and fixed metal outer loop 1 prevents that metal outer loop 1 from trembling.

The working principle is as follows: when the wind direction changes, the rotating rod 11 is subjected to a horizontal rotating force, because the second metal tooth 12 is fixedly connected to the outer part of the rotating rod 11, the first metal tooth 10 is clamped with the second metal tooth 12, the rotating rod 11 will drive the first metal teeth 10 to rotate horizontally, and because the first metal teeth 10 are fixed outside the inner metal ring 9, so the metal inner ring 9 will be stressed, and the metal ball 8 is movably connected between the metal inner ring 9 and the metal middle ring 5, when a horizontal force is applied to the metal ball 8, the metal ball 8 will remove a part of the horizontal force, when force is applied to the metal middle ring 5, the force is reduced partially, and because the rubber ring 4 and the spring 3 are arranged inside the metal middle ring 5 and the metal outer ring 1, the horizontal force given to the rotating rod 11 is further reduced, so that the impact resistance effect of the bearing is improved, and the bearing is effectively prevented from being broken.

In summary, the rotation shaft which is not easy to break of the wind power generation windmill is used by matching the rotation rod 11 with the metal inner ring 9, the first metal teeth 10 and the second metal teeth 12, when the rotation rod 11 rotates, the first metal teeth 10 are clamped with the second metal teeth 12 because the second metal teeth 12 are fixed on the rotation rod 11, so that the rotation rod 11 can drive the first metal teeth 10 to rotate, and the first metal teeth 10 are fixedly connected inside the metal inner ring 9, so that the rotation rod 11 can drive the metal inner ring 9 to rotate, thereby achieving the effect of changing the direction according to the wind direction. Through the cooperation of metal zhong huan 5 and spring 3, rubber circle 4 uses, when metal zhong huan 5 atress, its outside has rubber circle 4 and spring 3 can form the decompression effect for the impact force that receives when metal zhong huan 5 direction of rotation is reduced, makes the bearing have certain impact resistance, thereby has reduced the cracked risk of bearing.
