Abstract
The utility model belongs to electrical conducting technical field and relates to an electricity collecting ring, which applies to motors with electricity collecting rings and comprises an inner ring, an outer ring and a rolling body, all made of metal or alloy of good conductivity. The inner surface of the outer ring has a rolling contact with the rolling body while the outer surface of the inner ring has a rolling contact with the rolling body. The inner ring has an electric connection with a rotor winding terminal. The outer ring has an electric connection with an outer circuit. The electricity collecting ring of the utility model does not need electric brush, has a simple structure, small mechanical friction, a long service life time, good conductivity and good operational property.
Description
Technical field
The utility model belongs to the conductivity technical field, relates to a kind of collector ring, and it is applicable to the motor of collector ring.
Background technology
At present, the collector ring that known motor is used is the cylindric conducting strip of being made by copper or alloy, and the collector ring terminals connect the rotor winding terminal, and brush contacts with the collector ring intimate, and the brush terminals connect outer circuit.Collector ring and rotor rotate together, and the relative motion between brush and the collector ring produces friction, causes loose contact and is easy to generate electric spark.The motor that has is carried brush device for the mechanical friction loss that reduces brush and collector ring also is connected to.
The utility model content
The purpose of this utility model be to provide a kind of need not brush, simple in structure, mechanical friction is little, long service life, conduction are good, the novel collector ring that runnability is good.
Collector ring of the present utility model comprises inner ring, outer ring, rolling element, all adopts conductivity good metal or alloy to make.Inner ring be fixed in the rotating shaft and and the rotating shaft insulation, it is electrically connected with the rotor winding terminal, the inner ring outer surface contacts with the rolling element rolling.Inner surface rolls with rolling element and contacts, and the position is electrically connected with outer circuit in addition.When motor rotated, inner ring rotated with rotor, and rolling element rolls separately, and the outer ring is fixed on the shell.Link tester is crossed inner ring, rolling element, outer ring and is connected.Need not brush thereby reached, reduce the mechanical friction loss greatly, greatly improve the useful life of collector ring, the purpose that runnability improves.
Below in conjunction with accompanying drawing and example the utility model is further specified.
Description of drawings
Fig. 1 is the front view of first embodiment of the utility model.
Fig. 2 is the I-I cutaway view of Fig. 1.
Fig. 3 is the perspective view of second embodiment of the utility model.
Fig. 4 is the perspective view of the 3rd embodiment of the utility model.
1. outer rings among the figure, 2. rolling element, 3. inner ring, 4. spring, 5. retainer.
Embodiment
In Fig. 1, the outer surface of the inner surface of outer ring (1) and inner ring (3) is made spill as shown in Figure 2, thereby prevents that rolling element from rolling out between inner ring (3) and outer ring (1).Inner ring (3) is fixed on the machine shaft and with rotating shaft and insulate, and inner ring (3) is electrically connected with the leading-out terminal of rotor winding, and the method for attachment technology adopts existing rotor winding to connect the technology of collector ring.Outer ring (1) is electrically connected with outer circuit.For outer ring (1) better being fixed and being made collector ring contact of the present utility model better, between outer ring (1) and motor casing, connect an extension spring (4).
In example shown in Figure 3, the outer surface of the inner surface of outer ring (1) and inner ring (3) is made spill as shown in Figure 2, and inner ring (3) is fixed on the machine shaft and with rotating shaft and insulate, and inner ring (3) is electrically connected with the leading-out terminal of rotor winding.Outer ring (1) is electrically connected with outer circuit.Connect an extension spring between outer ring (1) and the motor casing.Rolling element embeds in the retainer (5).
In example shown in Figure 4, adopt present known rolling bearing directly to constitute outer ring of the present utility model (1), rolling element (2), inner ring (3), retainer (5).For improving its conductivity, can plate the good and wear-resisting metal or alloy of one deck conduction on the rolling bearing surface.Rolling element (2) is made into cylindrical shape, thereby it is long-pending to increase conductive contact surfaces.
Claims (2)
1. collector ring, it is characterized in that: outer ring, inner ring, rolling element are all made with conduction good metal or alloy, and inner surface rolls with rolling element and contacts, and the inner ring outer surface rolls with rolling element and contacts, inner ring is electrically connected with the rotor winding terminal, and the outer ring is electrically connected with outer circuit.
2. collector ring according to claim 1 is characterized in that: outer ring, inner ring, rolling element by rolling bearing plate on its surface one deck conduction good and wear-resisting metal or alloy constitute.
