Abstract

The utility model discloses an electric brush guide which consists of rotary shafts, guide retainers, electric brushes, electric brush frames, electric brush wires, conductive rings and guide surfaces; the electric brushes on a stator and the conductive rings on a rotor are correspondingly contacted in a sliding way one by one; and the guide retainers matched with the conductive rings are arranged at the two sides of each conductive ring. The guide surfaces inside the two guide retainers limit the electric brush wires on the electric brushes to be contacted with the corresponding conductive rings in a sliding way. The electric brush guide is characterized in that the upper end of the section of the guide retainer is a tread; the two waists of the guide retainers form a guide angle between 20 and 45 degrees. The electric brush guide is characterized in that the electric brushes on the stator are arranged on the electric brush frames; a left set of electric brushes and a right set of electric brushes are arranged corresponding to the rotor; and the two electric brushes form a guide angle between 45 and 90 degrees. The electric brush guide has the beneficial effects as follows: the electric brush wires on the electric brushes are led to be contacted with fixed conductive rings in a sliding way to not generate mutual playing to influence the normal work of guide sliding rings through the reasonable arrangement of the structures of the guide sliding rings.

Description

A kind of brush guider

[technical field]

The utility model relates to transmitting device accessory technical field, particularly a kind of technical field of brush guider.

[background technology]

In well-known modern age, in the high-end field of industrial equipment, the requirement such as polynary relative motions such as revolution, rotations is arranged more.Be 360 ° of plant equipment when rotatablely moving continuously, also need polynary motion on the rotary body.Motion is arranged, just need the energy, as electric energy, the fluid pressure energy etc.Sometimes, also need the control signal source, as fiber-optic signal, high-frequency signal etc.Any rotation relatively continuously between 360 ° the electric component needs different energy sources media such as transfer function power supply, weak electric signal, light signal, air pressure, hydraulic pressure, oil pressure, to guarantee that electrical equipment can also free-moving electromechanical equipment when rotatablely moving, all must use the rotation communication apparatus.

Slip ring is whole to rely on elastic force overlap joint principle, roll overlap joint principle or sealing principle, and cleverly motion structure and design of Sealing Structure, accurate part make cooperate, rational selection etc., constitute reliable and stable rotation connected system.As long as slip ring is attached on the equipment of unlimited rotation, just can provide power source to rotary body, make rotary body when infinitely rotatablely moving, can also carry out the working condition under other motion or the detection rotation status.

Slip ring is installed in the pivot of equipment usually, mainly is made up of with static two large divisions rotation.The rotational structure of rotating part connection device also rotatablely moves thereupon, is called " rotor ", and the energy of the fixed structure of stationary part connection device is called " stator ", and stator and rotor are by the brush sliding contact.

And the brush on the stator with the conducting ring sliding contact of rotor in be one to one, and the spigot surface layout of each conducting ring both sides conduction spacer ring of traditional slip ring is unreasonable, cause easily brush brush silk on the stator slide in not corresponding conducting ring on, influence the operate as normal of slip ring.

[utility model content]

For solving above deficiency, the utility model provides novel a kind of brush guider, this installs brush silk and the corresponding one by one sliding contact of epitrochanterian conducting ring on the brush that its reasonable structural design can make slip ring, and the normal use that play influences slip ring does not take place, this apparatus structure is simple and practical, has very strong usability.

It is made up of a kind of brush guider gyroaxis, guiding spacer ring, brush, brush carrier, brush brush silk, conducting ring, spigot surface; Brush on the stator and the corresponding one by one sliding contact of epitrochanterian conducting ring are equipped with corresponding with it guiding spacer ring in each conducting ring both sides.Brush silk sliding contact on the conducting ring of correspondence on the spigot surface restriction brush of two guiding spacer ring inboards;

A kind of brush guider is characterized in that the upper end in its cross section of described guiding spacer ring is a tread, and its two waists formation angle is the guide angle between the 20-45 degree;

A kind of brush guider is characterized in that described stator power up brush is installed on the brush carrier, two cover brushes about be equipped with corresponding with rotor, and two brushes constitute the guide angle between the 45-90 degree.

The beneficial effects of the utility model are: the reasonable setting of this device by its guide link structure makes the sliding contact and the operate as normal that mutual play influences slip ring does not take place on set conducting ring of brush silk on the brush.

Further understand feature of the present utility model and technology contents for making, see the utility model drawings and embodiments for details, yet appended graphic only for reference and explanation usefulness is limited the utility model.

Figure (2) the utility model guiding spacer ring stereogram:

Figure (3) the utility model A-A cutaway view;

The 101-spacer ring that leads; The 102-brush; The 103-brush carrier; The 104-gyroaxis; 105-brushes silk; The 106-conducting ring; The 107-spigot surface.

[embodiment]

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

A kind of brush guider is by the 101-spacer ring that leads; The 102-brush; The 103-brush carrier; The 104-gyroaxis; 105-brushes silk; The 106-conducting ring; The 107-spigot surface is formed.

As shown in Figure 1-Figure 3, on the 102-brush stuck-at-03-brush carrier with corresponding being equipped with of epitrochanterian 106-conducting ring about two cover its two 102-brushes and 105-brush silks constitute angle between the 45-90 degree, rotor rotates round the 104-gyroaxis, epitrochanterian 106-conducting ring and 101-guiding spacer ring constitute a 107-spigot surface, and the 105-brush silk of 102-brush contacts in 107-spigot surface inner slide.

This device cooperates the 105-brush silk of realizing the 102-brush contact and can only contact in this 107-spigot surface inner slide in 107-spigot surface inner slide by 101-guiding spacer ring and 107-spigot surface make the slip ring operate as normal.

Yet the preferable feasible embodiment of above-mentioned only the utility model, non-so limitation the utility model protection range is done various distortion or is applied mechanically all within this technical scheme protection range according to the foregoing description.
