AI Technical Summary
Traditional mechanical seals cannot be adapted to high-speed generator equipment, resulting in oil spills in the cavity and inability to effectively prevent air leakage.
The labyrinth oil blocking ring design replaces the traditional mechanical sealing member. The labyrinth oil blocking ring is installed on the rotor shaft and is snapped to the inner wall of the end cap to form a sealing structure.
It effectively prevents the oil from overflowing in the cavity, and solves the problem that traditional oil seals cannot be adapted to high-speed operation, ensuring the sealing of the generator during high-speed operation.

Abstract
Description
Technical Field
[0001] This application relates to the field of motor technology, and more particularly to a high-temperature resistant starting generator. Background Art
[0002] Mechanical seal is a shaft seal device for rotating machinery, such as equipment like generators. Since the transmission shaft runs through the inside and outside of the equipment, there is a circumferential gap between the shaft and the equipment. The medium in the equipment leaks out through this gap. If the pressure inside the equipment is lower than the atmospheric pressure, air leaks into the equipment. Therefore, there must be a shaft seal device to prevent leakage. There are many types of shaft seals. Due to the advantages of less leakage and long life of mechanical seals, mechanical seals are the most important shaft seal method for these equipment in the world today. However, traditional mechanical seals cannot be adapted to high-speed rotating generator equipment. Summary of the Utility Model
[0003] The high-temperature resistant starting generator provided by this application adopts the following technical solutions:
[0004] A high-temperature resistant starting generator, comprising: a first end cover, a second end cover, a housing, a rotor, a stator, and two labyrinth oil baffle rings. The first end cover and the second end cover are relatively fixed to the housing. The stator is fixed to the inner wall of the housing. The rotor is fixed to the first end cover and the second end cover through bearings. The labyrinth oil baffle rings are arranged on the rotating shaft of the rotor. One of the labyrinth oil baffle rings is clamped to the inner wall of the first end cover, and the other labyrinth oil baffle ring is clamped to the inner wall of the second end cover.
[0005] In one embodiment, the first end cover is provided with a first sealing cover, and the second end cover is provided with a second sealing cover.
[0006] In one embodiment, the first end cover is provided with a mounting seat, and the mounting seat is provided with a plurality of mounting interfaces.
[0007] The high-temperature resistant starting generator provided by the embodiments of the present disclosure can achieve the following technical effects:
[0008] Adopting the labyrinth oil baffle ring design to replace the traditional mechanical seal component, on the one hand, it helps to prevent the oil in the cavity from overflowing, and on the other hand, it helps to solve the problem that the traditional oil seal cannot be adapted to high-speed operation.
