Generator

Abstract

The invention discloses a generator which comprises a main shaft, an oil removal plate, an oil guiding casing, a bearing pedestal, a pillar screw and a radial thrust bearing, wherein the radial thrust bearing is arranged on the bearing pedestal, and the two ends of the main shaft are respectively arranged in the radial thrust bearing; a radial bearing bush is arranged on the inner wall of the radial thrust bearing; a thrust bearing bush is arranged at the outer side of the radial thrust bearing, and the thrust bearing bush is fixed on the radial thrust bearing by using the pillar screw; a platinum thermal resistance is arranged at the outer side of the thrust bearing bush; a hand oil pump is arranged on the bearing pedestal, and a cooler is arranged at the bottom of the bearing pedestal and is used for cooling lubricating oil; the oil removal plate is arranged inside the bearing pedestal and is sheathed on the oil guiding casing; and the oil guiding casing guides oil to the radial thrust bearing. According to the technical scheme of the invention, the generator bears the radial load and axial load of the main shaft; and the bearing bush is made of a babbitt metal material with good wear resistant performance and soft performance and can effectively protect the main shaft, thereby the service life of the generator is prolonged.

Description

technical field [0001] The invention relates to a generator, in particular to a generator with a long service life using a thrust bearing, and belongs to the technical field of power generation equipment. Background technique [0002] At present, common generators include a main shaft. The main shaft is arranged on a bearing, and the bearing is an ordinary bearing. Because the working condition of the generator is relatively complex, it is often subjected to axial and radial impact; The above impact is mostly transferred to the main shaft and the bearing. The generator of this structure, due to the frequent wear of the main shaft and the bearing, will be scrapped due to excessive wear of the bearing or the main shaft in a short period of time, thus requiring maintenance and replacement. SUMMARY OF THE INVENTION [0003] In view of the above existing technical problems, the purpose of the present invention is to provide a generator with a long service life using a thrust be...

Problems solved by technology

[0002] At present, common generators include a main shaft, and the main shaft is arranged on bearings, and the bearings are ordinary bearings; since the working conditions of the generator are relatively complicated, they are often subjected to axial and radial impacts; Most of the above shocks will be transferred to the main shaft and bearings. Due to the frequent wear of the main shaft and bearings, the generator with this structure will be scrapped due to excessive wear of the bearings or main shaft in a short period of time, which requires maintenance and replacement.
