Problems solved by technology
[0002] For single-bearing (three-point support) wind turbines, the drive chain is connected to the frame through three-point supports, and the elastic supports on both sides of the gearbox are two of the support points to stabilize the drive chain. In the inner hole of the rotating arm of the gearbox, the elastic support shaft is fixed to the inner hole of the rotating arm after the bearing bush is compacted, which is difficult to disassemble. Therefore, the elastic supporting wind field of the gearbox is usually damaged, and the main crane needs to be used to dismantle the wind wheel and the transmission chain Afterwards, return the drive chain to the factory for maintenance, which is difficult and costly

The invention relates to an elastic support replacement tool for a gearbox of a wind generating set, and belongs to the technical field of wind generating set equipment. The elastic support replacement tool for the gearbox of the wind generating set comprises a support fixedly installed on the gearbox, lead screws are vertically arranged on the two sides of the top of the support, the bottom ends of the lead screws downwards penetrate through the support and then stretch into a dismounting cylinder to be in threaded connection with an elastic supporting shaft of the gearbox, a dismounting cylinder is arranged at the end of the elastic supporting shaft in a sleeving mode, the elastic supporting shaft is wrapped by a bearing bush at the upper end and a bearing bush at the lower end, an adjusting nut is arranged at the top end of each lead screw, and the lead screws ascend by screwing down the adjusting nuts, so that the elastic supporting shaft and the bearing bush at the upper end are tightly pressed; and by loosening the adjusting nuts, the lead screws descend, so that the elastic supporting shaft is separated from the bearing bush at the upper end. The replacement tool has the beneficial effects that: the elastic supporting piece can be rapidly replaced, large crane equipment is not needed, and cost and time are saved.
