Abstract
The utility model relates to a ship device, and particularly relates to the improvement of a ship-mounted shafting grounding device. The adjustable electric brush positioning device comprises an electric brush frame, wherein a mandrel for positioning the electric brush frame, at least two electric brush seats provided with the electric brushes, and an electric brush spring which is matched with the electric brush seat are mounted on the electric brush frame, and the electric brush seat is rotatably fixed on the electric brush frame through a screw thread connecting piece. The adjustable electric brush positioning device regulates the mutual positions between the electric brushes aiming at the rotating shafts with different shaft diameters, leads the electric brush to be positively pressed on a rotary shaft or a slide ring, and leads the electric brush and the rotating shafts to be well conducted.
Description
Technical field
The utility model relates to ship equipment, relates in particular to the improvement of marine shafting earthing device.
Background technology
In the boats and ships running, couple corrosion can take place in shell outer different metal part (as shell, blade) each other in seawater, had a strong impact on the useful life of boats and ships.Operation to boats and ships is very unfavorable, and its main cause is the current potential difference of the different metal part in the seawater, thereby each other electron transfer can take place, thereby forms couple corrosion.The thinking that solves couple corrosion is that the current potential of different metal part in the seawater is equated, stops electron transfer between the different metal part with this.Concrete scheme is with graphite electrode and jack shaft or the good ground that is coupling of screw electrically conducting, and will draw electric wire and the electric edge joint of shell on the graphite electrode, thereby forces screw to equate with the current potential of shell, and electron transfer does not take place each other.The key that realizes such scheme be graphite electrode with rotating shaft between whether keep good the contact, owing to have phenomenons such as circular runout, axial endplay and hull vibrations in the rotating shaft running, not only need certain contact pressure between graphite electrode and the rotating shaft, and the center line of graphite electrode is crossing substantially with the axis of rotating shaft, so that graphite electrode is close to and malleation on rotating shaft, and present marine shafting earthing device often can not well be accomplished this point during at the diameter of axle that differs in size.
The utility model content
At the prior art above shortcomings, the purpose of this utility model is that a kind of adjustable brush positioner will be provided, it can make the brush malleation on rotating shaft or slip ring at the mutual alignment between the rotating shaft adjustment brush of the different diameters of axle, makes the good conducting of brush and rotating shaft.
In order to solve the problems of the technologies described above, the scheme of the adjustable brush positioner of the utility model technical solution problem is: a kind of adjustable brush positioner, comprise brush carrier, the axle, at least two that this brush carrier of location is installed on this brush carrier install brushes brushgear housing and with the supporting brush spring of described brushgear housing, described brushgear housing is rotating to be fixed on the described brush carrier by threaded connector.
After adopting such scheme, because brushgear housing is rotating to be fixed on the brush carrier by being threaded, thereby rotating shaft at the different diameters of axle, can adjust the position of each brushgear housing by unclamping the threaded connector of fixing each brushgear housing, make the axis of the center line of each brushgear housing and rotating shaft crossing substantially, screwing up threaded connector then, make brushgear housing location and be fixed on the brush carrier, thereby make brush malleation in the brushgear housing, keep good conducting state on the surface of rotating shaft or slip ring.
Four brushgear housings generally are installed on the brush.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the adjustable brush positioner of the utility model is described in further detail.
Fig. 1 is the structural principle schematic diagram of the adjustable brush positioner of the utility model.
Embodiment:
Among Fig. 1, be installed with axle 5 on the brush carrier 4, axle 5 is fixedly mounted on the hull, four brushgear housings 2 are installed on the brush carrier 4, four brushgear housings 2 are symmetrically distributed with the symmetrical center line of brush carrier 4, brushgear housing 2 is fixedly mounted on the brush carrier 4 by threaded connector 7, threaded connector 6 is a unit bolt nut spare, brush 3 is installed in the brushgear housing 2, the spring 1 that compresses brush 3 is installed on the brush carrier 4, when real ship is installed, threaded connector 7 with fixed brush seat 2 on the brush carrier 4 unclamps earlier, and make the mid point on each brushgear housing 2 base all tangent with the slip ring 6 that is installed on the rotating shaft, screwing up threaded connector 7 then, each brushgear housing 2 all is fixedly mounted on the brush carrier 4, again the axle on the brush carrier 45 is fixedly installed on the hull, and to make the mid point on brushgear housing 2 bases and the distance between the slip ring 6 be 5mm, with the time collision brushgear housing 2 that prevents the rotating shaft circular runout, cause brushgear housing 2 displacements, and cause brush 3 can not malleation on slip ring 6, after adjusting the position of brushgear housing 2 and installing brush carrier 4, brush 3 is put into brushgear housing 2, and spring 1 is pressed on the brush 3.
Claims (3)
1. adjustable brush positioner, comprise brush carrier (4), the axle (5), at least two that this brush carrier of location (4) is installed on this brush carrier (4) install brushes brushgear housing (2) and with the supporting brush spring (1) of described brushgear housing (2), it is characterized in that: described brushgear housing (2) is rotating to be fixed on the described brush carrier (4) by threaded connector (7).
2. a kind of adjustable brush positioner according to claim 1 is characterized in that: described brushgear housing (2) is symmetrically distributed with the symmetrical center line of described brush carrier (4).
3. a kind of adjustable brush positioner according to claim 1 is characterized in that: described threaded connector (7) is the assembly of bolt, nut, packing ring formation.
