Anti-loose anti-bending automatic compensation fastening bolt structure of large clean energy equipment

Abstract

The invention discloses an anti-loose anti-bending automatic compensation fastening bolt structure of large clean energy equipment. The structure comprises a bolt through hole formed in a connecting flange of a first rotating part and a fastening bolt arranged in the bolt through hole, the fastening bolt is sleeved with a compensation gasket, and the compensation gasket comprises a lower gasket body and an annular upper gasket body. A plurality of elastic supporting pieces are arranged between the upper gasket and the lower gasket, the maximum compressible amount of each elastic supporting piece is a, the initial compression amount of each elastic supporting piece is b, b is smaller than a, when the elastic supporting pieces are in the actual working state, the axis of the first rotating piece and the axis of the second rotating piece are bent into an arc shape, the maximum actual compression amount of each elastic supporting piece is c, the minimum actual compression amount of each elastic supporting piece is d, a-c is larger than or equal to 1 mm, and b-d is larger than or equal to 2 mm. According to the invention, the self-loosening of the fastening bolt can be prevented, and the anti-bending fatigue strength of the fastening bolt can be obviously improved, so that the safety of large clean energy equipment is improved.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a large-scale clean energy equipment anti-loosening and anti-bending automatic compensation joint bolt structure. Background technique [0002] With the enhancement of people's awareness of energy conservation and environmental protection, clean energy equipment is being vigorously developed. When clean energy equipment is in operation, large components such as the main shaft, frame, rotor, and top cover will bear radial unbalanced forces, bending moments, pressure, high-temperature and low-temperature media, especially rotating parts such as the main shaft. There will be a certain bending deflection when rotating, that is to say, the end face of the rotating part will be inclined to a certain degree at this time, so that the bolts arranged between the end faces of the two rotating parts and used to connect the two rotating parts A certain degree of bending is generated, and the...
