Background technology
Bearing is the parts of the most accurate core of motor, supports the rotational structure of motor, makes motor even running.Simultaneously by
In the motor sound structural transition role that bearing undertakes, it is also the parts that motor fret is the most serious, need to make regular check on, more
Change.
For solution own vol and the locomotive installing space contradiction between limited, locomotive traction motor is usually taken without transmission
The single bearing structure of end end cap, i.e. when motor is installed, motor coordinates face to serve as motor-driven end end cap with gear-box, motor and
Gear-box is integrated.This result in its change bearing time, the car that falls, entrucking step sufficiently complex, change bearing mistake
Cheng Zhong, the risk that locomotive and motor cause artificial damage is higher, and the process changing bearing is time-consuming, take a lot of work, arduously, and cost is high.
So exigence one can change bearing locomotive traction motor online now.
Accompanying drawing 1 show the structural representation of existing locomotive traction motor non-transmision end；It includes support 1, non-transmision end
End cap 2, rotor 3, internal sealed ring 4, bearing 5, end ring 6, inner cap 7, speed measuring fluted disc 8, enclosing cover 9, bearing angle circle 10.Due to locomotive
The restriction in space, the bearing removal process car that must be fallen by motor can realize, and this electric machine structure cannot realize changing bearing online
Purpose.During dismounting bearing, end cap and rotor one need to be departed from stator, rear dismounting enclosing cover 9, speed measuring fluted disc 8, inner cap
7, end ring 6, bearing angle circle 10, then end cap is separated with rotor with bearing entirety, then by forcing press frock by bearing pressure
Go out.From above bearing removal process, whole job step is loaded down with trivial details and it needs to special frock has been operated by professional
Becoming, so motor car to be fallen also needs to return factory is replaced bearing simultaneously, whole process wastes time and energy, with high costs.
Summary of the invention
The present invention solves the problem that existing locomotive traction motor cannot change bearing online, it is provided that one can change axle online
The traction electric machine held.
The present invention adopts the following technical scheme that realization: can change the traction electric machine of bearing online, including support, non-biography
