In the prior art, it is circular structure that conducting slip ring, which generallys use cross section, shown in Figure 4.Conducting slip ring Need to be adapted to various application environments, especially various narrow environment, especially certain equipment are in installing process, some direction Space it is more narrow, the space of other direction is more loose, then with this condition, how to adjust the structure of conducting slip ring with suitable Environmental requirement is answered, in a limited space, rotor internal diameter is expanded as far as possible, and then improves the application longevity of conducting slip ring Life, improving stability is this field urgent problem to be solved.

Summary of the invention

The technical issues of the utility model solves is, by optimal setting mode, so that in a limited space, rotor The available expansion of internal diameter.

Further, operational reliability, signal stabilization, the service life of conducting slip ring are promoted.

The utility model discloses a kind of conducting slip ring, which has slip ring shell, slip ring internal layer and brush, The slip ring internal layer and the brush are located at the slip ring enclosure interior, the slip ring internal layer around a rotary shaft be arranged, with the rotation In the vertical plane of axis, there is orthogonal first direction and second direction, which is arranged along the first direction, the cunning Toroidal shell body can just accommodate the slip ring internal layer in the second direction.

The slip ring shell is stator, which is rotor, alternatively, the slip ring shell is rotor, which is Stator.

The slip ring shell is fixed in the brush one end, and the other end is set in the collector ring of the slip ring internal layer.

The slip ring internal layer is fixed in the brush one end, and the other end is set in the collector ring of the slip ring shell.

The intracorporal loading plate of the slip ring shell is fixed in the brush one end, and the other end is set to the collector ring of the slip ring internal layer In.

The length of slip ring shell in the first direction is greater than the length in the second direction.

Specific embodiment

The realization process that the technical solution of the utility model is described below in conjunction with specific embodiment, not as practical new to this The limitation of type.

It is as shown in Figure 1 the schematic cross-section of the conducting slip ring of the utility model.

A kind of conducting slip ring 100 has slip ring shell and slip ring internal layer, and in the present embodiment, which is fixed Sub- shell 12, slip ring internal layer are rotor 11.The conducting slip ring 100 also has brush 13, and the rotor 11 and the brush 13 are located at Inside the stator case 12.The rotor 11 is rotated around a rotary shaft 10.

In the plane vertical with the rotary shaft 10, there is orthogonal first direction A and second direction B.The electricity Brush 13 is along the two sides that the rotor 11 is arranged in first direction A setting, the especially brush 13.One end of the brush 13 is fixed on The stator case 12, the other end are set in the collector ring of the rotor 11.The collector ring is in electrical contact for being formed with brush, and And accommodating brush is played, when rotor 11 rotates, the brush is limited in the collector ring, the effect of nonvoluntary swing.The stator Shell 12 is close to the rotor 11, so that the stator case 12 can just accommodate the rotor 11 on second direction B.In fact, should Collector ring both can be set in slip ring shell, also can be set in slip ring internal layer, according to need depending on, when the collector ring is set to this When slip ring shell, which is securable to the slip ring internal layer, and the other end is placed in the collector ring.

Due to brush 13 and it is not disposed on second direction B, so width of the conducting slip ring 100 in second direction B can be with Greatly reduce so that entire width of the conducting slip ring on second direction B be essentially identical to the rotor diameter and twice The thickness of shell of stator case 12.

Due to brush and for connecting and the associated structural component of fixed brush is respectively provided in a first direction, then this is fixed The length of sub- shell in the first direction is greater than the length in the second direction.

Again due to brush and for connecting and the associated structural component of fixed brush is respectively provided in a first direction, so In the confined space, the length in the second direction can be supplied to rotor 11 with almost all, can be in conditional space In, increase the diameter of rotor 11 as far as possible, the perimeter of the collector ring of rotor 11 is promoted, to increase brush 13 and rotor 11 Contact, further to promote operational reliability, signal stabilization, the service life of conducting slip ring.

In another embodiment, it please refers to shown in Fig. 2, which is fixed on the carrying in the stator case 12 Plate 14, the other end are set in the collector ring of the rotor 11.

By the way that brush 13 is fixed on loading plate 14 rather than stator casing, so that connection is more firm, lift structure is stablized Property.

The cross section of the stator case 12 has straight-line profile in the first direction.The cross section of the stator case 12 exists Also it can have camber line shape in the second direction.In order to match the shape of the rotor, the placement of the further expansion rotor is empty Between, the cross section of the stator case 12 can also have fold-line-shaped in the first direction, as shown in Figure 3.The cross of the stator case Section may be to make full use of the needs in the space of equipment mounted, and be designed as with straight line in the second direction Shape or broken line shape.

Under practical application scene, the role of the stator and rotor be can be interchanged, that is, the slip ring shell of label 12 in Fig. 1 It can be rotor, the slip ring internal layer of label 11 can be stator, and the slip ring shell of the label 12 can be rotated around the rotary shaft 10, The slip ring internal layer of label 11 can be remain stationary with respect to the rotary shaft 10.

In order to further reduce cross-sectional area shared by conducting slip ring, can also be arranged shown in FIG. 1 in the rotor The brush 13 of 11 two sides, the ipsilateral of the rotor 11 is arrived in setting, to improve the utilization rate of the device space of specific direction.

Above-described embodiment is only the exemplary description for realizing the utility model, without the protection to limit the utility model Range, protection scope please refer in rear accessory claim book subject to record.
