Abstract
The utility model relates to a rare-earth permanent magnet retarded type starting motor for vehicles, which is characterized in that stator magnetic poles adopt Nd-Fe-B rare-earth permanent magnet magnetic poles; every pole is formed by the splicing of two pieces of magnetic shoes and is glued on a stator housing with bicomponent epoxy glue; the rare-earth permanent magnet magnetic poles has the advantages of high magnetic energy, low temperature coefficient, etc. Compared with the same class products, the utility model has the advantages of small size, light weight, high specific power, reliable performance, etc. The utility model fundamentally ensures the working reliability of a motor particularly under the condition of starting torque lowering caused by low air temperature in winter, large internal resistance of a storage battery and small discharge current.
Description
This is suitable for novel a kind of miniature actuating motor that relates to, particularly the micromachine of motorcycle electricity starting.
At present, the starting of motorcycle engine develops into electricity starting by foot pedal starting, employing be the battery-driven DC start motor of vehicle-mounted microminiature.Starting is convenient, and is strong rapidly, makes the application of motorcycle improve a class.The actuating motor of homemade motorcycle assembling as matching parts and motor together from abroad buying, the actuating motor structural feature of buying is to adopt ferrite as excitatory magnetic pole, because ferrite magnetic energy is lower, the volume of actuating motor is reduced or weight saving is subjected to certain restriction, in order to make the actuating motor production domesticization, we research and develop on the basis of introducing product.
It is little that the purpose of this utility model provides a kind of volume, in light weight, and than merit height, reliable performance is particularly useful for the motorcycle starting motor of cold area.
A kind of rare earth permanent magnet slowdown type vehicle-mounted starting motor is by the stator cage that has magnetic pole (1), be contained in the armature assembly (2) in the casing (1), and the transition end cap (3) that links of casing (1) and drive end cap (4), be fixed on the brush spring (5) on the transition end cap (3), the live axle (6) of band gear, be contained in the sprocket wheel (7) on the live axle (6), support armature assembly (2) and live axle (6) bearing (8), seal arrangement (9) is formed, it is characterized in that a pair of magnetic pole on the stator cage (1) is the Nd-Fe-B rare-earth permanent magnet magnetic pole, every utmost point is pieced together by two magnetic shoes and is formed, with the two component epoxy glue bond on stator cage (1), the axle head of armature assembly (2) has the gear engagement on gear and the live axle (6), reduction speed ratio i=3～8 are for the heat that distributes actuating motor is opened an air outlet hole downwards on driving end cap (4).
The rare earth permanent magnet magnetic pole, have magnetic energy height, characteristics that temperature coefficient is low, under rugged environment, do not produce permanent demagnetization during electric motor starting, compare with like product according to the actuating motor that these characteristics optimal design go out, have volume little, in light weight, than advantages such as merit height, reliable performances, especially in the winter time temperature is low, and accumulator internal resistance is big, discharge current is little and cause under the situation that starting torque descends, and has fundamentally guaranteed the reliability of machine operation.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing is a longitudinal section of the present utility model tectonic maps.
Among the figure: 1. stator cage 2. armature assemblies 3. transition end caps
4. drive end cap 5. brush springs 6. live axles
7. sprocket wheel 8. bearings 9. seal arrangements
Stator cage (1) is the monolithic construction by the iron plate drawing and forming, magnetic pole adopts the Nd-Fe-B rare-earth permanent magnet magnetic pole, every utmost point is put together by two magnetic shoes, with the two component epoxy glue bond on stator cage (1), transition end cap (3) and driving end cap (4) link by screw and casing, the brush spring (5) that brush is housed is screwed on transition end cap (3), live axle (6) and sprocket wheel (7) pass through splined, live axle (6) and gear interference fit, live axle (6) is supported on transition end cap (3) by oil-impregnated bearing and ball bearing and drives on the end cap (4), and armature assembly (2) is bearing on stator cage (1) and the transition end cap (3) by oil-impregnated bearing and ball bearing.The reduction speed ratio i=6.625 of gear, the sprocket wheel (7) that is contained on the live axle (6) drives engine start by chain-driven.Drive end cap (4) and motor, stator cage (1) and transition end cap (3) adopt the seal with elastometic washer of O type, adopt the sealing of rubber asbestos packing between transition end cap (3) and the driving end cap (4).
Claims (1)
1, a kind of rare earth permanent magnet slowdown type vehicle-mounted starting motor is by the stator cage that has a pair of magnetic pole, be contained in the armature assembly in the casing, the transition end cap that links with casing and drive end cap, be fixed on the brush spring that transitioning end covers, the live axle of band chain wheel, be contained in the sprocket wheel on the live axle, support the bearing of armature assembly and live axle, seal arrangement is formed, and it is characterized in that a pair of magnetic pole on the stator cage is the Nd-Fe-B rare-earth permanent magnet magnetic pole, and every utmost point is abandoned to close by two magnetic shoes and formed, with the two component epoxy glue bond on stator cage, the axle head of armature assembly has the gear engagement on gear and the live axle, and reduction speed ratio i=3～8 cover at drive end and to open an air outlet hole downwards.
