Background technique
Rod end comprises bearing body, and one end of bearing body is provided with tapped hole, the other end is provided with housing, is equipped with steel ball in housing, is provided with brass liner between housing and steel ball.Shell inner hole is cylindrical, after brass liner is compressed into housing, need shell inner hole edges at two ends to third side to rushing riveting, to reach the object of fixing brass liner, but there is gap between housing and brass liner, make rod end bearing impact resistance more weak and not wear-resisting, in use easily produce and loosen, even occur disintegration.For solving the problem, have devised injection molding type screw jointing type spherical plain bearing rod end.China Patent No. be 2009201478462, Authorization Notice No. is cn201407281U, name is called in the patent document of " injection molding type spherical plain bearing rod end " and namely discloses a kind of injection molding type screw jointing type spherical plain bearing rod end.Injection molding type spherical plain bearing rod end is brass grommet to change into and forms with composite material and to be injection-moulded between housing and steel ball.Although good than brass bushing of injection molding type spherical plain bearing rod end wear resistance, do not add lubricant oil and can rotate yet, wear resistance does not still add the good of lubricant oil.
Model utility content
The utility model provides a kind of oily and injection molding type screw jointing type spherical plain bearing rod end that fuel filler neck direction is adjustable of can carrying out, and solving existing injection molding type spherical plain bearing rod end can not oily problem of carrying out lubricating.
Above technical problem is solved by following technical proposal: a kind of injection molding type screw jointing type spherical plain bearing rod end, comprise bearing body, one end of described bearing body is provided with tapped hole, the other end is provided with housing, steel ball is equipped with in described housing, the inwall of described housing is provided with injection slot, grommet is injected with in described injection slot, described steel ball supports with in described housing by described grommet, described steel ball is provided with axis hole, it is characterized in that, also comprise bindiny mechanism, described housing is provided with the through tank filler sleeve to described steel ball, described tank filler sleeve mating spherical surfaces is hinged with fuel filler neck, described fuel filler neck is fixed together with described housing by described bindiny mechanism, bolt on the face that the same housing that described bindiny mechanism comprises compact heap and drives compact heap to be pressed into fuel filler neck coordinates, described bolt is threaded togather with housing.The process that the utility model carries out refueling is, rotating bolt and make compact heap unclamp pressing fixation to fuel filler neck, then rotate fuel filler neck as required can connect with nozzle easily to the entrance point of fuel filler neck, and then rotate backward bolt, bolt drives compact heap and to be pressed on fuel filler neck thus to realize the fixing of fuel filler neck and housing, is finally docking together with fuel filler neck by oil gun and is added between steel ball and injection moulding grommet by lubricant oil.Convenience during oiling is good.
The utility model also comprises the bracing ring described fuel filler neck being supported in described tank filler sleeve, is Spielpassung between described fuel filler neck and tank filler sleeve.Easily laborsaving when can make to rotate fuel filler neck.
As preferably, described bracing ring is fixed in described tank filler sleeve.When fuel filler neck can be made no matter to turn to that angle, fuel filler neck and housing can both reliably link together by bracing ring.
As preferably, described fuel filler neck is provided with ballhead, and described tank filler sleeve is provided with spherical cavity, and described fuel filler neck is connected in described spherical cavity hinged with tank filler sleeve by described ballhead.Compact structure, connects reliable.
As preferably, the center line of described bolt is through the center of fuel filler neck and tank filler sleeve fitting surface.Can reduce further compact heap be pressed on fuel filler neck on the surface time damage to fuel filler neck surface.
As preferably, be mating spherical surfaces between described compact heap and fuel filler neck.The surface failure of compact heap to injection moulding grommet is little, can increase the service life.
The utility model has following advantage: can refuel, and improves the wear resistance of bearing; The direction of fuel filler neck is adjustable, and convenience during oiling is good, oil gun is interfered with circumferential component and the phenomenon that can not refuel when can not produce oiling.
