Description
Technical field
The utility model relates to a kind of carbon brush component, refers to a kind of current-collector carbon brush component especially.
Background technology
At present, because of sheet molding compound (Sheet Molding Compound, be called for short SMC) good insulation preformance, most current-collector carbon brush components all adopt the insulating support of SMC material, this insulating support one side is provided with securing bracket and bearing support, and opposite side is provided with the connection copper bar, plays insulation and isolates, but the insulating support of SMC material is squeezed variations in temperature when big, easily fracture.This carbon brush component directly adopts securing bracket and the middle mode stationary positioned that clamps bearing support of insulating support.Existing securing bracket is a flat board, and during to the fastening location of carbon brush component, securing bracket is pressed in the bearing support upper surface, and the metal nuts that fastening bolt passes in securing bracket and the insulating support spins mutually.The tightening pulling force of metal nuts has certain requirement in fastening bolt and the insulating support, and as too loose, carbon brush component can't accurately be located; As too tight, supported extruding of insulating support is in case when variations in temperature was big, insulating support just was easy to fracture.Special in the bigger zone of the seasonal weather temperature difference, it is intact all having when carbon brush component has just been installed; But through after a while, insulating support expands with heat and contract with cold because of climate change and ruptures, cause carbon brush component accurately to locate, carbon brush and slip ring are noncontact, or the contact pressure deficiency, cause outage, break signal, signal weakening, and produce arcing between carbon brush and slip ring, cause whole current-collector to be scrapped, consequence is very serious.
The utility model content
The technical problems to be solved in the utility model is the problem that exists at above-mentioned current-collector carbon brush component, provides a kind of and is not affected by climate change, the anti-cracking current-collector carbon brush component of stable, long service life.
The technical solution of the utility model is: anti-cracking current-collector carbon brush component, comprise bearing support, insulating support, be located at the connection copper bar of insulating support one side, be fixed in the bearing that connects the copper bar opposite side, both sides, bearing lower end are provided with connecting rod, be provided with extension spring between connecting rod and the bearing, the connecting rod end is provided with carbon brush, the carbon brush outside by conductor with to be connected the electrical connection of copper bar two ends fastening, it is characterized in that: the opposite side of insulating support is provided with down " U " shape securing bracket, the securing bracket top wears adjusts bolt pair, baseplane, securing bracket both sides and insulating support Joint.
Securing bracket described in the utility model has some bending parts, left-right symmetric; Described securing bracket top ends links to each other with middle bending part by last bending part, and middle bending part is bent into the baseplane by 90 degree; The nut that fastening bolt passes in securing bracket baseplane and the insulating support is spirally connected.
Bearing support described in the utility model is a hollow square tube, and it is located in the securing bracket, and this square tube end angle is fillet, and its lower end is located in the groove of insulating support, when adjustment bolt pair is not tightened, has the gap between described securing bracket and the bearing support.
Compare with prior art, the beneficial effects of the utility model are: when adjustment bolt pair is not tightened, have the gap between described securing bracket and the bearing support, carbon brush can carry out moving of each orientation with respect to bearing support, promptly carry out forward and backwardly, move the left, right, up, down; When adjustment bolt pair is tightened, described securing bracket top ends both sides spacing is adjusted the secondary extruding of bolt and diminishes, a securing bracket left side, corresponding the diminishing of upper right bending part spacing, left simultaneously, the bending part spacing also diminishes in the right side, a drive securing bracket left side, right vertical portion extruding bearing support both sides, thereby carbon brush component is fixed on the bearing support, have only the bearing support both sides stressed this moment, its upper and lower side does not stress, therefore bearing support can the extruding insulation support, insulating support can not cause cracked because of variation of temperature, has prevented arcing or outage that carbon brush is untouchable, phenomenons such as break signal.This carbon brush component is adapted at the bigger place of the temperature difference and uses its weatherproof, stable, long service life.In addition, in the time of need reorientating carbon brush component, only need unscrew and adjust the bolt pair, regulate the position of carbon brush component, tighten adjustment bolt pair again and get final product, it is in installation, convenient, simple and direct when regulating the location.
