The current technology has such defects as low strength, poor impulse and vibration resistant performance, instable electric signal transmission and low insulation resistance, thus the application range is quite limited and not suitable for use under the high temperature, pressure or humidity environment. However, the utility model comprises an inner body case component and an outer body case component; wherein the inner body case component comprises an inner body case, an inner insulating ring and a plurality of conduction rings, while the outer body case comprises an outer body case, an outer insulating ring and a plurality of conduction pieces; and a plurality of grooves are arranged on the outer insulating ring corresponding to the conduction rings, and the conduction piece is a sheet spring electric brush 1, the connection terminal of which is fixed on the outer insulating ring, while the other terminal is arranged in the groove and elastically pressed on the conduction ring. The utility model has the advantages of high strength, impulse resistance, good shock resistant performance, and reliable electric signal transmission and good sealing capacity.
Description
Affiliated technical field:
The utility model belongs to the oil drilling equipment technical field, is specifically related to a kind of slip ring that is used for the oil steering drilling tool.
Background technology:
Slip ring in the oil steering drilling tool mainly is used in the transmission of carrying out multi-channel electric signal between the dynamic and static rotary body of oil steering drilling tool, comprise inner housing assembly and shell body assembly, the inner housing assembly comprises interior dead ring that inner housing, inner housing inboard are embedded and several conductive rings on the interior dead ring, the shell body assembly comprises external insulation ring that shell body, shell body inboard are embedded and several conducting pieces on the external insulation ring, shell body one end is provided with the sealed wiring post, the wiring of sealing prap is passed wiring hole and is connected conducting piece, and the wiring on the conductive rings is passed wiring hole and drawn.The slip ring of this structure is widely used under the environment of normal temperature, normal pressure, normal humidity at present, but because this structural strength is low, shock-resistant, resistance to shock is poor, signal of telecommunication transmission is unstable, dielectric strength is low, therefore the scope of application is limited especially, and incompatibility is used under the adverse circumstances of high temperature, high pressure, high humidity.
Summary of the invention:
The utility model will provide a kind of slip ring that is used for the oil steering drilling tool, and is limited especially to overcome the scope of application that prior art exists, the incompatible shortcoming of using under the adverse circumstances of high temperature, high pressure, high humidity.
For overcoming the shortcoming that prior art exists, technical solution of the present utility model is: a kind of slip ring that is used for the oil steering drilling tool, comprise inner housing assembly and shell body assembly, the inner housing assembly comprises inner housing 1, interior dead ring 8 and several conductive rings 7, the shell body assembly comprises shell body 2, external insulation ring 9 and several conducting pieces, its special character is: the external insulation ring 9 corresponding to several conductive rings 7 is provided with several grooves, described conducting piece is a sheet spring formula brush 11, the terminals of this brush 11 are fixed on the external insulation ring 9, and the other end is arranged in the groove and suppresses on conductive rings 7.
2 of above-mentioned inner housing 1 and shell bodies axially are symmetrically arranged with roller bearing 3
2 of above-mentioned inner housing 1 and shell bodies have been disposed radially ball bearing 4.
Be provided with axle envelope 10 in above-mentioned between the inner housing 1 of dead ring 8 and external insulation ring 9 both sides and the shell body 2.To keep the equilibrium oil in the sliding chamber not leak.
Compared with prior art, the utility model has the advantages that:
1, intensity height, shock-resistant: double-shell structure, the dielectric strength height, shock-resistant, thereby be suitable under the abominable working environment of high temperature, high pressure, high humidity, working.
2, anti-seismic performance is good: be disposed radially bearing 4 between inner housing and shell body, played the effect that alleviates vibrations.
3, signal of telecommunication transmission is stable, reliable: an end of sheet spring formula brush is by the elasticity of brush body itself, elastic force with about 100 grams contact with conductive rings on the interior dead ring, this simple and direct integrated brush, remove the contact resistance between brush contact and brush body from, can greatly improve the transmission stability and the servo-actuated that contacts with conductive rings of the signal of telecommunication.
4, good airproof performance: be the pressure of balance external bound pair slip ring, make slip ring core institute oiling liquid be unlikely leakage, added axle envelope between the inner housing of interior dead ring and external insulation ring both sides and the shell body, therefore high temperature resistant, high pressure, high humidity.
