Shaftless generator and axle sensing communication system

Abstract

The invention provides a shaftless generator and an axle sensing communication system. The shaftless generator comprises a stator. One end face of the stator is provided with an accommodation groove.A number of coils are embedded in the bottom plate of the accommodation groove. The shaftless generator further comprises a rotor which can be detachably assembled with an external rotating shaft andcomprises a rotor disk correspondingly arranged on one side or both sides of the accommodation groove. A number of permanent magnets which are arranged with spacing are fixedly arranged on the end face, which is opposite to the accommodation groove, of the rotor disk. Two adjacent permanent magnets have opposite polarities. The rotor is suspended. When the external rotating shaft drives the rotorto rotate, a number of coils cut the magnetic lines of the permanent magnets to generate electromotive force. Through the technical scheme of the invention, the installation requirements of various harsh installation environments can be satisfied; the external rotating shaft drives the rotor to rotate, so that the coils on the stator cut the magnetic induction lines; current is generated in the coils to provide power for a designated power system; and separately adding a power supply system is not needed.

Description

technical field [0001] The invention relates to the field of generators, in particular to a shaftless generator and an axle sensor communication system. Background technique [0002] In the related art, since freight cars often need to be grouped during operation, that is, the freight cars are not fixed on a train like the passenger cars, so there is no power supply system for the freight cars on the railway at present, resulting in the fact that the freight cars are generally not installed with any electrical appliances. Devices, such as sensors and communication components, cannot be equipped with a power supply system to supply power to the complete sensor system like the passenger car compartment, so as to ensure safe operation and realize continuous speed increase of passenger trains. [0003] Since the train carriages do not have a power supply system, there are defects in the management of the railway carriages by the railway operation department, especially the manag...

Problems solved by technology

[0002] In the related art, since freight cars often need to be grouped during operation, that is, the freight cars are not fixed on a train like the passenger cars, so there is no power supply system for the freight cars on the railway at present, resulting in the fact that the freight cars are generally not installed with any electrical appliances. Devices, such as sensors and communication components, cannot be equipped with a power supply system to supply power to the complete sensor system like passenger cars, so as to ensure safe operation and realize continuous speed increase of passenger trains

[0003] Since the train carriages do not have a power supply system, there are defects in the management of the railway carriages by the railway operation department, especially the management of the axles. Inaccurate control of the maintenance cycle, resulting in problematic axles that cannot be repaired in time, and axles that have not yet reached the maintenance cycle may have been repaired, resulting in waste of management costs

[0004] In addition, due to the inability to realize real-time detection of the temperature and vibration of the train axle, the railway department also lacks effective informatization and automation means for the management of freight vehicles and their operation, which seriously hinders the operation efficiency of freight trains, and there are potential safety hazards that hinder Implementation of the speed-up plan for freight trains like passenger trains
