AI Technical Summary

Technical Problem

The planetary carrier of traditional gearboxes has high flexibility, large torsion deformation and high stress, resulting in low reliability. The existing improvement methods increase weight and cost, and the local stress increases, which is not conducive to improving the reliability of the gearbox.

Method used

By changing the load transfer path, a gear box is designed, and its planet carrier includes a connecting shaft, a pair of spokes plates and a support body. The planetary shaft is inserted into the plug holes of the spokes plates and abuts with the limiting part to form a barrier cavity to block the load transfer path and reduce stress.

Benefits of technology

Without increasing the weight and cost of the gearbox, the reliability of the gearbox is effectively improved and the stress of the planetary carrier in the intersecting area between the inner wall of the plug-in hole and the limiting part is reduced.

Abstract

The invention relates to a gear box and a wind generating set, the gear box comprises a planet carrier, the planet carrier comprises a connecting shaft, radial plates arranged in pairs and a supporting body, the supporting body is connected between the radial plates arranged in pairs, the connecting shaft is arranged on one of the radial plates, and insertion holes are oppositely formed in the radial plates; the side, away from the other radial plate, of the inserting hole of at least one radial plate is covered with a limiting part. The planet shaft is inserted into the oppositely arranged insertion holes and is supported on the planet carrier; the transmission wheel is arranged on the planet shaft and can rotate relative to the planet carrier by taking the axis of the planet shaft as the center; in the axial direction, the planet shaft partially abuts against the limiting part, and a partial area of at least one of the planet shaft and the limiting part is arranged in a sunken mode in the direction away from the other one, so that the planet shaft and the limiting part are partially spaced in the axial direction, and a blocking cavity is formed. According to the gear box and the wind generating set provided by the embodiment of the invention, the reliability of the gear box can be improved by changing the load transfer path.
