Abstract
The utility model discloses a self -cooled permanent -magnet machine belongs to motor technical field, and its structure includes front end housing, casing and rear end cap, the front end installation that the front end housing passes through bolt and casing together, the main shaft is installed together to the rear end installation that the rear end cap passes through bolt and casing in the casing, the front side of main shaft is passed through the fore bearing and is installed on the front end housing, the rear end of main shaft is passed through the rear bearing and is installed on the rear end cap, installs the rotor on the main shaft. The utility model discloses a self -cooled permanent -magnet machine compares with prior art, has reasonable in design, simple structure, easy characteristics such as processing, and this permanent -magnet machine does not have fan blade, nos fan housing, noise and hangs down, bearing interval 415mm from beginning to end, than traditional permanent -magnet machine's bearing hypotelorism 180mm, reduced the size of the electric machine, the effectual manufacturing cost that has reduced has improved the work efficiency of dismouting.
Description
Technical field
The utility model relates to technical field of motors, specifically self cool magneto.
Background technology
Existing motor radiating generally adopts coaxial fan blades radiating mode, magneto also continues conventional motors structure always, adopt coaxial fan blades radiating mode, this structure does not play the advantages such as magneto high effect, low heating, not only processing cost is high to make magneto, and dismounting operation is loaded down with trivial details, wastes time and energy, add long wheelbase and power to weight ratio.
summary of the invention
Technical assignment of the present utility model is for above weak point, provides that a kind of distance between bearings is short, the self cool magneto of low cost of manufacture.
The utility model solves the technical scheme that its technical problem adopts: this magneto comprises front end housing, casing and rear end cap, front end housing is installed together by the front end of bolt and casing, rear end cap is installed together by the rear end of bolt and casing, in described casing, main shaft is installed, the front side of main shaft is arranged on front end housing by fore bearing, the rear end of main shaft is arranged on rear end cap by rear bearing, and main shaft is provided with rotor.
Distance between described fore bearing and rear bearing is 415mm.
The both sides, front and back of described fore bearing fasten fore bearing gland, and the both sides, front and back of rear bearing fasten rear bearing gland.
By set bolt, magnet steel back-up ring is installed in described rotor, along magnet steel back-up ring, multiple magnet steel is evenly installed, is provided with multiple every bore between main shaft and magnet steel back-up ring, every bore and magnet steel one_to_one corresponding.
Self cool magneto of the present utility model compared to the prior art, have reasonable in design, structure simple, be easy to the features such as processing, this magneto Bladeless, low without fan housing, noise, front and back bearings spacing 415mm, 180mm is shortened than the distance between bearings of conventional permanent magnet motor, reduce motor volume, effectively reduce manufacturing cost, improve the operating efficiency of dismounting.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Accompanying drawing 1 is the detonation configuration schematic diagram of self cool magneto.
Accompanying drawing 2 is the cross sectional view of rotor.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1:
Self cool magneto of the present utility model, its structure comprises front end housing 2, casing 4 and rear end cap 8, front end housing 2 is installed together by the front end of bolt and casing 4, rear end cap 8 is installed together by the rear end of bolt and casing 4, main shaft 5 is installed in casing 4, the front side of main shaft 5 is arranged on front end housing 2 by fore bearing 3, and the both sides, front and back of fore bearing 3 fasten fore bearing gland 1; The rear end of main shaft 5 is arranged on rear end cap 8 by rear bearing 7, and the both sides, front and back of rear bearing 7 fasten rear bearing gland 9; Distance between fore bearing 3 and rear bearing 7 is 415mm, main shaft 5 is provided with rotor 6, by set bolt 13, magnet steel back-up ring 12 is installed in rotor 6, along magnet steel back-up ring 12, multiple magnet steel 10 is evenly installed, be provided with multiple every bore 11 between main shaft 5 and magnet steel back-up ring 12, every bore 11 and magnet steel 10 one_to_one corresponding.
The self cool magneto of said structure, Bladeless and fan housing, simplify the structure of magneto, reduce production cost, and make magneto dismounting time saving and energy saving; Front and back bearings spacing 415mm, than the front and back bearings hypotelorism 180mm of conventional permanent magnet motor, reduces motor volume.
By embodiment above, described those skilled in the art can be easy to realize the utility model.But should be appreciated that the utility model is not limited to above-mentioned several embodiments.On the basis of disclosed execution mode, described those skilled in the art can the different technical characteristic of combination in any, thus realizes different technical schemes.
