Description
Technical field
The utility model relates to a kind of ac variable frequency speed regulation asynchronous traction motor, especially relates to a kind of ac variable frequency speed regulation asynchronous traction motor that is applicable to electric mine locomotive.
Background technology
At present, generally mostly the motor of electric motor car of Shi Yonging is direct current machine, supplies with direct current by storage battery to direct current machine.This electric motor car that drives by direct current machine, the speed adjustable range of its direct current machine is narrow, poor reliability, the life-span is short, and efficient is low, and inconvenient maintenance greatly reduces the serviceability of motor.
And some present ac variable frequency speed regulation motor seal poor performance, the problem that may have the bearing grease loss on the one hand, can not prevent effectively that on the other hand the high temperature oil of gear tank from entering motor internal, thereby very easily damage the electrical machine insulation performance, cause burn-down of electric motor.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, the ac variable frequency speed regulation asynchronous traction motor of good seal performance.
The purpose of this utility model is achieved through the following technical solutions:
It comprises front end housing, stator, rotor, fan, rear end cap, and support upper horizontal position is provided with outlet box, and lead-in wire is fixed on the outlet box after support is drawn; The stator slot of stator core is embedded with stator coil, behind the stator coil end line, draws tie from wire hole; Rotor adopts interference fit to be fixed in the rotating shaft; The shaft extension end bearing is covered with seal groove outward, cooperates with the seal ring seal groove; Drive of motor end and gear are in the fuel tank hermetically-sealed construction together.
Preferred version: the set seal groove of shaft extension end bearing enclosing cover is the labyrinth seal groove, and the seal groove of seal ring also is the labyrinth seal groove, and both labyrinth seal grooves match, and can guarantee motor normally operation under specific condition.
The utility model can be by the power supply of stringing formula power supply; Electric machine structure is simple and reliable, easy maintenance; Utilize seal groove structure, can effectively protect motor, guarantee the normal safe operation of electric locomotive.
The utility model can fully satisfy the performance requirement of mining tunnel engineering vehicle to traction motor.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is that shaft extension end bearing enclosing cover seal groove embodiment illustrated in fig. 1 cooperates enlarged diagram with the seal ring seal groove.
Among the figure: 1. front end housing, 2. fan, 3. rotor, 4. stator, 5. support, 6. outlet box, 7. rear end cap, 8. bearing end cover, 9. seal ring, 10. axle sleeve.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to accompanying drawing, present embodiment comprises front end housing 1, stator 4, rotor 3, fan 2, rear end cap 7, and support 5 upper horizontal positions are provided with outlet box 6, and lead-in wire is fixed on the outlet box 6 after support 5 is drawn; The stator slot of stator core is embedded with stator coil, behind the stator coil end line, draws tie from wire hole; Rotor 3 adopts interference fit to be fixed in the rotating shaft; Shaft extension end bearing enclosing cover 8 is provided with the labyrinth seal groove, cooperates with seal ring 9 labyrinth seal grooves; Seal ring 9 is fixed on the axle sleeve 10; Drive of motor end and gear are in the fuel tank hermetically-sealed construction together.
The labyrinth seal groove of bearing end cover 8 cooperates with the labyrinth seal groove of seal ring 9, both can prevent that bearing grease runs off, and can prevent that again the high temperature oil of gear tank from entering motor internal, and damage electrical machine insulation, causes burn-down of electric motor.
