Problems solved by technology

The asymmetrical mounting structure leads to inevitable vibration and drift of the stator 5, so the railway generator may be easily damaged
Therefore, it does not seem possible to implement railway axle-end generators onto car bogies using conventional load-carrying saddles

[0094] like Figure 3A and 3B As shown, the shaft end generator assembly of this embodiment has a load saddle assembly. The saddle assembly has a split structure comprising: i) a first portion 610 obtained by modifying a conventional saddle, wherein the first portion 610 can pass through a groove 614 formed thereon (see Figure 4C ) to a car truck, eg, in a similar manner to a conventional saddle; and ii) a second portion 620 connected to the first portion 610 via screws 630 . The first part 610 and the second part 620 together form a base for mounting the stator of the shaft end generator.

[0095] In this embodiment, the first portion 610 is the upper portion and can support the bogie payload, and the second portion is the underside portion and does not support the bogie payload. However, the present disclosure is not limited thereto, and the first part 610 and the second part 620 may also be a right part and a left part, respectively. The first and second portions 610, ...

[0117] Figure 5A and 5B A shaft end generator assembly in a second embodiment of the present disclosure is schematically shown. exist Figure 5A and 5B , some components of the generator assembly are omitted to clearly show the structure.

[0118] This embodiment has a similar concept to the first embodiment, and only the differences therebetween will be described below.

[0119] like Figure 5A and 5B As shown, the saddle assembly has a split structure comprising: i) a first part 610 obtained by modifying a conventional saddle, wherein the first part 610 can be mounted to the car truck through a groove 614 formed thereon, and the first part 610 is A portion 610 supports the bogie payload; and ii) a second portion 620 connected to the first portion 610, wherein the second portion 620 does not support the bogie payload. The first part 610 and the second part 620 have similar structures and can be replaced with each other.

Abstract

The present disclosure provides a bearing saddle assembly and a shaft end generator assembly of a generator. The saddle assembly includes a first portion configured for mounting to a car truck and a second portion connected to the first portion, and a second portion configured to together form a stator for mounting an electrical generator base.

Description

technical field [0001] The present disclosure relates to load saddle assemblies and shaft end generator assemblies for generators. Background technique [0002] Railroad wagons previously did not have electrical power supplies because electrical applications were rarely implemented on railroad wagons in the past. [0003] However, with the development of railway wagons, with more sensors and mechatronics components implemented on the wagons, power solutions have become a key requirement. [0004] A disk-type permanent magnet generator has been proposed as a power supply for railway wagon cars. [0005] Disc generators are an easy-to-install, reliable and economical power solution for railway applications. [0006] The disc generator can be mounted on the car bogie by fitting to the axle box, which is robust during operation. [0007] Disc generators have a rotor and a stator. The rotor is mounted on the shaft end, so the generator can also be called a shaft end generator...
