Embodiment
The utility model discloses a kind of slip ring, on the basis that guarantees its performance, prolong the useful life of slip ring.
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1 and Fig. 2, the slip ring that the utility model embodiment provides comprises:
Be coated at the stationary part 2 of rotor portion 1, the outer wall of this stationary part 2 and copper ring 4 relative positions offer aperture 8, and the brush line 3 of stationary part 2 passes aperture 8, and contacts with copper ring 4; The brush line 3 that welds lead inserts in the aperture 8 on shell bodies 7 surfaces, aperture 8 and copper ring 4 corresponding one by one (as shown in Figure 5) on the mandrel 6, and its effect is to be used for fixing brush line 3, line 3 is brushed in the location, makes to brush line 3 and just in time align with copper ring 4;
Its core inventive point is, the structure of brush line 3 is monolateral brush, and promptly 4 of each copper rings contacts with the brush line 3 of one side of something, plant the performance that structure not only can not have influence on slip ring, have also reduced to brush the friction between line and the copper ring greatly.
Compare with the structure in the tradition, the slip ring that the utility model embodiment provides, its brush line 3 adopts the structure of monolateral brush; Be that 4 of each copper rings contact with the brush line 3 of one side of something; This structure not only can not have influence on the performance of slip ring, has also reduced the friction between brush line 3 and the copper ring 4 widely, has slowed down both wearing and tearing; Prolong the useful life of slip ring, thereby can satisfy the specific (special) requirements of some specific area.
In order to optimize above-mentioned technical scheme; The brush line 3 of slip ring adopts hexa-atomic alloy material in the present embodiment; This kind material good toughness, wear-resisting, and its surface do not need electroplating processes has avoided copper ring 3 all to electroplate with brush line 4 and the caducous problem of coating during the friction that causes; And reduce the generation of powder, guaranteed the overlength useful life of slip ring.
Further, the material composition of copper ring 4 meets GB/T 5231-2001 national standard, and its surface adopts craft of gilding to handle; Be coated with the gold layer, and coating is even, smooth; No bubble point, sags and crests were transferred 5 minutes in the condition of 300 ℃ of high temperature, and coating does not have foaming, obscission.Not only make copper ring 4 conductivity better, and make copper ring 4 more wear-resisting, increased the useful life of slip ring.
The place that its brush line 3 of existing slip ring contacts with copper ring 4 does not have follow-up processing; To this point, the slip ring that the utility model embodiment provides, the surface of its copper ring scribbles 758G lubricating oil; This kind oil not only can not have influence on the electric property of slip ring; And making the friction between brush line 3 and the copper ring 4 littler, the powder of generation is few more, thereby has increased the useful life of slip ring.
The slip ring that the utility model embodiment provides can be under 24 hours uninterrupted rotating conditions, run well 2,000 ten thousand change more than, meet the specific (special) requirements of some specific area.
As shown in Figure 3; Be provided with the insulating barrier that forms evagination by the injection moulding encapsulating between adjacent two copper rings 4; Copper ring 4 is fixed on the mandrel 6 through insulating barrier, and this insulating barrier not only makes copper ring 4 be fixed on the mandrel 6, and makes the requirement that reaches dielectric voltage withstand between adjacent two copper rings 4.
Further, the outer peripheral face of copper ring 4 offers U type groove, and brush line 3 is erected in the U type groove; This kind design be for mandrel 6 when rotated, make the brush line that contacts with copper ring 43 be difficult for jumping brush, the swinging of restriction brush line 3; Better controlled the stable of signal or electric current, the performance that guaranteed product; And make frictional force between the two reach minimum value, make the more smooth of mandrel 6 rotations.Also be welded with lead on the ring in the said copper ring 4, mainly for electric current or signal are transferred on the copper ring 4 through lead.
Please with reference to Fig. 4; Stationary part 2 comprises shell body 7 and is set in shell body 7 cap sleeve 9 on every side; The shell body 7 that installs brush line 3 attaches together in mandrel 6 outsides, last whole cap sleeve 9 the insides that are contained in, and this cap sleeve 9 can play the effect of protection internal structure and fastening shell body 7.
Further, shell body 7 comprises two semicircular housings, and about attach together into round.
The utility model embodiment also provides a kind of communication system; Comprise fixture, whirligig and slip ring, this slip ring is the slip ring with half of brush configuration above-mentioned, and useful life is longer; Can be from the fixture data signal to whirligig; Reduce the friction between the part, prolonged useful life, thereby can satisfy the specific (special) requirements of some specific area; And this kind of joint volume is little, and can change overall dimension according to installing space.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
