Abstract
The utility model provides a rod end oscillating bearing, which comprises a casing, a ball rod, a dust shield and a steel ring, wherein one end of the casing is provided with a through hole, the steel ring is fixed in the through hole, the ball end of the ball rod is arranged in the steel ring, and the other end penetrates through the dust shield, the inner periphery of the through hole on the upper end of the dust shield is tightly matched with the outer periphery of the ball rod, the bottom surface of the dust shield is matched with the upper surface of the casing in a sealing way, a framework is arranged in the dust shield, and the framework is arranged in the upper end of the dust shield. The rod end oscillating bearing can increase the sealing property of the dust shield and the ball rod, thereby improving the sealing property of products.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of spherical plain bearing rod end that uses on the chassis of automobile.
Background technique
Spherical plain bearing rod end is widely used on the automobile chassis, existing automobile ball head pull rod shaft is contracted and is drawn together housing, ball rod, spring, steel ring, the plastics seat ring, cover plate and dust-proof cover, wherein, described housing one end is provided with a through hole, steel ring is positioned at described through hole, the bulb end of ball rod is positioned at steel ring, the other end of ball rod passes described dust-proof cover, the upper side of dust-proof cover and the outer circumferential face of described ball rod are sealed and matched, the bottom surface of dust-proof cover cooperates with described housing seal, be provided with a plastics seat ring that has a spring between the outer circumferential face of steel ring inner peripheral surface and described bulb end, the automobile ball head pull bar bearing of this structure, when assembling, need earlier steel ring to be put into housing, put into bolt shank then, put into the plastics seat ring again, on plastic ring, put spring again, putting into cover plate at last assembles, therefore, assembly process is loaded down with trivial details, manufacturing efficiency is lower, owing to used these component of spring, make product axial carrying capacity a little less than, because ball rod and steel ring carry out mill, in use wear extent is bigger, shortened the working life of product, and because dust-proof cover is a rubber material, cooperate with ball rod and housing seal, occur distortion easily, thereby reduced the sealing of product.
The model utility content
Technical problem to be solved in the utility model provides a kind of rod end bearing of simple in structure, easy to process and good seal performance.
In order to solve the problems of the technologies described above, a kind of spherical plain bearing rod end of the utility model, comprise housing, ball rod, dust-proof cover, steel ring, wherein, described housing one end is provided with a through hole, described steel ring is fixed in the described through hole, and the bulb end of described ball rod is positioned at described steel ring, and the other end passes described dust-proof cover; The outer circumferential face of described dust-proof cover upper side and described ball rod closely cooperates, and the bottom surface of described dust-proof cover and described housing upper surface are sealed and matched, and are provided with a skeleton in the described dust-proof cover, and described skeleton is positioned at the upper end of described dust-proof cover.
Above-mentioned a kind of spherical plain bearing rod end, wherein, described skeleton is a ring.
Above-mentioned a kind of spherical plain bearing rod end wherein, connects as one by injection-moulded plastic spare between described steel ring and the described ball rod.
Adopt a kind of spherical plain bearing rod end of said structure, owing to be provided with a skeleton in the dust-proof cover, can increase the force intensity that is subjected to of dust-proof cover and ball rod surface of contact, thereby improved the sealing of dust-proof cover and ball rod, and between steel ring and ball rod, be provided with a working of plastics, this working of plastics can be used as oiling agent, need not grease up, make product under the situation of no any lubricant grease, also can work, also greatly reduce the heat treatment of ball rod and steel ring and the requirement of material simultaneously, reduced the cost of product.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In order to solve the problems of the technologies described above, a kind of spherical plain bearing rod end of the utility model, comprise housing 1, ball rod 2, dust-proof cover 3, steel ring 4, wherein, described housing 1 one ends are provided with a cross through hole 11, described steel ring 4 is fixed in the described through hole 11, the other end can connect a plain radial bearing 7, be integral by the outer surface of described steel ring 4 fixedlyed connected with the internal surface interference fit of through hole 11, the bulb end of described ball rod 2 is positioned at described steel ring 4, the other end passes described dust-proof cover 3, links into an integrated entity by bolt or other modes with described dust-proof cover 3; Described dust-proof cover 3 is the cover body of rubber material, can be inverted bowl-type and also can be other shapes, the inner peripheral surface of dust-proof cover 3 upper-end surface through holes and the outer circumferential face of described ball rod 2 closely cooperate, the bottom surface of dust-proof cover 3 and described housing 1 upper surface are sealed and matched, be provided with a skeleton 21 in the described dust-proof cover 3, described skeleton 21 is positioned at the upper end of described dust-proof cover 3, described skeleton 21 is located in the dust-proof cover 3 by the mode that embeds, described skeleton 21 is ring, the cross section of skeleton 21 can be L shaped or other shapes, can be provided with a skeleton 21 in the lower end of dust-proof cover 3 in order to improve intensity, increase skeleton 21 at dust-proof cover 3, can increase the force intensity that is subjected to of dust-proof cover 3 and ball rod 2 and housing 1 surface of contact, make dust-proof cover 3 tightr with cooperating of housing 1 and ball rod 2, dust-proof cover 3 in use both had been difficult for coming off, also good seal, thereby improved the sealing that dustproof effect has improved product, be provided with a working of plastics 5 between the bulb end outer circumferential face of steel ring 4 internal surfaces and ball rod 2, this working of plastics 5 can be by injection-moulded plastic between steel ring 4 and ball rod 2, and form ball rod 2 and steel ring 4 are linked into an integrated entity, this working of plastics 5 can be used as oiling agent, play lubricated effect, make product under the situation of no any lubricant grease, also can work, also greatly reduce the heat treatment of ball rod 2 and steel ring 4 and the requirement of material simultaneously, reduced the cost of product.
The automobile ball head pull bar bearing of this structure when assembling, links into an integrated entity steel ring 4 and ball rod 2 earlier by injection-moulded plastic circle 5, then, the steel ring 4 and the connecting body of ball rod are put into housing 1, put into cover plate 6 at last and assemble, adopt this fit, the product assembly process is oversimplified.
The utility model is not limited to above-mentioned mode of execution, adopts equivalence to replace resulting technological scheme and also drops in the protection domain of the present utility model.
