High-power wind turbine generator elastic support and installation method

Abstract

The invention discloses an elastic support assembly for a generator of a high-power wind turbine generator system and a mounting method. The elastic support assembly is characterized in that elastomer is arranged right above a lower support plate; an upper casing is arranged right above the elastomer; a vertical central through hole in Z direction is formed right in the middle of the upper casing, the elastomer and the lower support plate; an upper mandrel is tightly sleeved with the upper casing through the central through hole; the mandrel is sleeved with the elastomer through the central through hole at an interval; the lower end of the upper mandrel is coaxially and fixedly connected with a lower mandrel; the lower mandrel penetrates the central through hole formed right in the middle of the elastomer and the lower support plate from top to bottom at an interval; the upper mandrel is connected with the lower section of a vertical regulation screw through an internal threaded through hole; an L-shaped movable plate is arranged on the top surface of the vertical regulation screw; an L-shaped fixed plate is fixedly connected to the top surface of the upper casing; a right-angle plate on the lateral side of a generator bracket is arranged above the movable plate. Two-way position regulation can be realized in the horizontal direction, an inclined block support mechanism is designed at a vertical position regulation place, and position regulation and precise positioning can be realized rapidly.

Description

technical field [0001] The invention belongs to the field of vibration-reducing, noise-reducing and impact-resistant parts, and in particular relates to an elastic support installed at the bottom of a generator of a wind power generating set, especially suitable for generator elastic supporting parts of a large-power wind generating set greater than 2.0MW. The generators of high-power wind turbines act as vibration dampers. Background technique [0002] In order to reduce the shock caused by the vibration during the working process of the high-power wind turbine, to protect the equipment and improve the operating life, several elastic supports need to be installed at the bottom of the high-power wind turbine, which are adjusted by elastic bodies and adjusting screws, so as to Buffers vibration shocks. Although the existing elastic supports of high-power wind turbines can realize the adjustment of a radial position and an axial position, they cannot satisfy the precise align...

AI Technical Summary

Problems solved by technology

Although the existing elastic supports of high-power wind turbines can realize the adjustment of a radial position and an axial position, they cannot satisfy the precise alignment between the output shaft of the generator and the transmission shaft, that is, they cannot meet the requirement of adjusting the output shaft of the generator in another radial position. adjustment

During use, due to the heavy weight of the generator, the load brought to the elastic support is large, so that the adjusting screw thread that adjusts the vertical movement of the elastic support is loosened, resulting in a change in the adjustment displacement; the elastic body in the elastic support is in use. The creep phenomenon in the wind turbine greatly reduces the service life of the elastic support of the wind turbine generator
