Below in conjunction with accompanying drawing, embodiments of the present invention are described in detail:
Be illustrated in figure 3 apparatus of the present invention composition structural representation, from figure, apparatus of the present invention by clamping plate 31, supporting bracket 32, flanged plate 33 and 2 brushes 34 form; As shown in Figure 4, clamping plate center has the circular hole that the stator module for magneto passes; As shown in Figure 5 and Figure 6, supporting bracket and flanged plate center have the circular hole that the rotor assembly for magneto passes; As shown in Figure 6, one is respectively had for placing the groove of brush at the two ends up and down of flanged plate center hole; Clamping plate, supporting bracket and flanged plate have position and match for the hole be connected to each other, as shown in Fig. 3,4,5,6;
Annexation:
Clamping plate 31 adopt welding manner to be fixedly connected with the housing 2 of magneto; Supporting bracket 32 is flexibly connected with clamping plate 31 by fastening assembly II 36; Two pieces brush 34 is embedded respectively after in the upper and lower groove of flanged plate 33 by tight fit and is flexibly connected with supporting bracket 32 by fastening assembly I 35; After connection, the center hole of clamping plate, supporting bracket and flanged plate is concentric structure.
As preferably, supporting bracket 32, flanged plate 33 are respectively equipped with for keeping the seam of concentricity with clamping plate 31, supporting bracket 32.
As preferably, fastening assembly I 35 and fastening assembly II 36 form by bolt, nut and spring washer.
As preferably, for ease of installing, supporting bracket 32 is made up of two pieces half supporting bracket.
As preferably, described clamping plate 31, supporting bracket 32 and flanged plate 33 are made by the hard metal material being easy to conduct electricity.
Illustrate genuine installation process and the site of deployment dismounting bearing pedestal process of apparatus of the present invention below:
Be illustrated in figure 1 the installation site schematic diagram of apparatus of the present invention in magneto, from figure, apparatus of the present invention 3 respectively install one group in magneto housing 2 front and back end, and concrete installation process is as follows:
When housing 2 makes, first clamping plate 31 and housing 2 are fixedly connected by welding, then the parts such as stator module 5 and rotor assembly 4 are installed according to former magneto mounting means, next 2 brushes 34 are embedded in the upper and lower groove of flanged plate 33 by tight fit, then flanged plate 33 is enclosed within rotor assembly 4, installs through housing 2 together with mounted stator module 5, front-end bearing pedestal assembly 1, rear bearing block assembly 6.Two pieces half supporting bracket is entered rear embedding in clamping plate 31 by seam from upper and lower both sides respectively and is combined into a supporting bracket 32 from air port, housing 2 side 7, then be fixedly connected with clamping plate 31 by fastening assembly II 36, flanged plate 33 is embedded in the supporting bracket 32 of two pieces half supporting bracket formation by seam, then is fixedly connected with supporting bracket 32 by fastening assembly I 35.
After installation, the magneto outward appearance adding 2 groups of apparatus of the present invention as shown in Figure 2, can see surface structure after the assembling of apparatus of the present invention 3 (2 groups) by the air port 7 after having removed shutter.
According to the installation site of apparatus of the present invention 3, in conjunction with permanent magnet motor structure, can to composition apparatus of the present invention 3 parts: clamping plate 31, the shape of supporting bracket 32 and flanged plate 33 carries out accommodation, as the present embodiment middle clamp plate 31 two ends respectively have a groove, and two ends, bottom respectively have a rectangular opening, as shown in Figure 3.
Field stripping bearing pedestal process is as follows:
When field stripping front-end bearing pedestal assembly 1 and rear bearing block assembly 6, the rotor assembly 4 that originally dependence front-end bearing pedestal assembly 1 and rear bearing block assembly 6 are located is in free state, the now constraint of rotor assembly 4 relies on two groups of apparatus of the present invention 3 upper flange plates 33 to support, and avoids rotor assembly 4 and stator module 5 due to together with magnetic-adsorption.Concrete bearing replacing process not within the scope of the present invention, therefore, repeats no more herein; User can carry out dismounting according to product operation instruction.
In sum, installing and using of brush 34, make the axle head electric current that rotor assembly 4 produces due to eddy current, electric machine casing 2 can be discharged into via flanged plate 33, supporting bracket 32 and clamping plate 31 by brush 34, and (when housing 2 is directly placed in ground placement, electric current is transferred to the earth by housing 2 to be transferred to the earth by housing 2; Other electric current is not transferred to the situation of the earth by housing 2, can increase the lead-in wire that is connected to the earth on housing), thus solve the infringement of magneto shaft current to bearing, extend the useful life of bearing, reduce use cost.And when motor bearings running was lost efficacy, apparatus of the present invention 3 can also be interim to rotor assembly 4 supporting role, avoid occurring because rotor assembly 4 and stator module 5 are because of " sweeping thorax " phenomenon together with magnetic-adsorption, make user can spot replace bearing, reduce its use cost.
Drawings describe embodiments of the present invention although combine, to those skilled in the art, under the premise without departing from the principles of the invention, can also make some distortion and improvement, these also should be considered as belonging to protection scope of the present invention.
