Problems solved by technology

[0004] But because there are many components connected between the rotor and the stator of the axle box generator, it is difficult to adjust and set the gap between the rotor and the stator
During the working process of the axle box generator, the gap between the rotor and the stator may change. When the gap between the rotor and the stator is smaller than the gap required for safe work, the rotor and the stator may collide with each other, so that the axle box The parts of the generator are damaged, which may even cause a safety accident

Embodiment Construction

[0026] It can be known from the background art that the axle box generator in the prior art cannot well maintain the safety gap between the stator and the rotor.

[0027] A specific description will be given below in conjunction with an axle box generator and a wheel set bearing.

[0028] Please refer to figure 1 , figure 1 It is a longitudinal section schematic diagram of an axle box generator and a wheel set bearing.

[0029] Such as figure 1 As shown, the axle box generator includes:

[0030] first end cap 1;

[0031] A stator 2, the stator 2 is fixedly connected to the first end cover 1;

[0032] A rotor 3, the end face of the rotor 3 is opposite to the end face of the stator 2 with a gap between them;

[0033] The second end cover 4 , the rotor 3 is fixedly connected with the second end cover 4 .

[0034] One of the stator 2 and the rotor 3 is provided with a coil, and the other is provided with a magnet. The axle box generator is installed on at least any one end...

Abstract

An embodiment of the invention provides an axle box generator. The axle box generator comprises a stator, a guide rail arranged on the radial outer side of the stator, a first end cover and an elasticpiece arranged between the stator and the first end cover, wherein the elastic piece can generate elastic deformation in the axial direction of the stator, the guide rail is relatively fixed to the stator in the circumferential direction of the stator, and the guide rail can move relative to the stator in the axial direction of the stator. Therefore, the axle box generator provided by the embodiment of the invention can reduce the impact influence caused by the acting force between the stator and the rotor in the working process, thus safety accidents are avoided; meanwhile, due to the fact that the guide rail is arranged on the radial outer side of the stator, an existing structure is slightly changed, the change cost can be saved, and a better stator movement guiding effect is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of generators, in particular to an axle box generator and a bogie. Background technique [0002] Freight trains are usually not equipped with a power source themselves. Until now, electrical systems in freight trains have been mainly powered by batteries, which provide a limited amount of power and limit the functionality of the system. [0003] In order to provide electrical energy to the equipment in the freight train that needs power, the axlebox generator can be integrated with the wheel set bearings to provide power to the freight train. [0004] However, because there are many parts connected between the rotor and the stator of the axle box generator, it is difficult to adjust and set the gap between the rotor and the stator. During the working process of the axle box generator, the gap between the rotor and the stator may change. When the gap between the rotor and the stator is small...
