Abstract
The utility model relates to a tripod assembly of new construction bearing mainly includes tripod and bearing, and the bearing assembly is on the tripod, and the bearing comprises outer lane, inner circle, kingpin and retaining ring, and the inner circle assembly is in the outer lane, and a plurality of kingpins are located between outer lane and the inner circle, and the last lower extreme of kingpin all is equipped with the retaining ring, and the inner wall of outer lane is equipped with interior raceway and tool withdrawal groove, and the retaining ring is fixed in the tool withdrawal groove. The utility model discloses profitable effect is: the utility model discloses a because the deep trouth design has been solved to the structure, the great problem of outer lane weight for the thickness of outer lane reduces, and weight reduction, occupation space diminishes, alleviates the processing degree of difficulty, has improved the machining precision, under operating condition, receives great axial force when unusual, and the difficult axial float of retaining ring has improved life.
Description
Technical Field
The utility model relates to a structure of tripod, especially a tripod assembly of new construction bearing.
Background
The tripod universal joint in the prior art comprises tripod stands, each tripod stand consists of a middle blank body and flat shaft heads of the three tripod stands, a ball ring consisting of an inner ring and an outer ring is sleeved on each flat shaft head of each tripod stand, a plurality of roller pins are arranged in a roller path between the inner ring and the outer ring, two annular grooves are respectively arranged at two ends of the outer ring, roller pin check rings are arranged in the annular grooves, and a tripod universal joint assembly is matched with a tripod groove shell after being connected with a shaft rod. The outer lane of prior art needs the exclusive use groove sword processing deep groove in order to guarantee that the snap ring assembly back does not drop, and for guaranteeing that the outer lane does not split, outer lane design thickness is great, and occupation space is big, and the snap ring groove adopts the groove sword to process, and groove width machining tolerance is big and the draw-in groove bottom is flat, makes the three ball round pin in the use, and the snap ring is easy to the kingpin and inner circle axial float, leads to the jamming to reduce life.
Disclosure of Invention
The utility model discloses the shortcoming of above-mentioned prior art is solved, a three round pin frame assemblies of simple structure, the longer new construction bearing of life are provided.
The utility model provides a technical scheme that its technical problem adopted: the three-pin frame assembly of the bearing with the new structure mainly comprises a three-pin frame and a bearing, wherein the bearing is assembled on the three-pin frame and consists of an outer ring, an inner ring, rolling needles and check rings, the inner ring is assembled in the outer ring, the rolling needles are positioned between the outer ring and the inner ring, the upper end and the lower end of each rolling needle are respectively provided with the check ring, the inner wall of the outer ring is provided with an inner raceway and a tool withdrawal groove, and the check rings are fixed in the tool withdrawal grooves.
And a transition structure is arranged between the tool withdrawal groove and the inner roller way.
The inner side of the tool withdrawal groove is provided with a slope.
The utility model discloses profitable effect is: the utility model discloses a because the deep trouth design has been solved to the structure, the great problem of outer lane weight for the thickness of outer lane reduces, and weight reduction, occupation space diminishes, alleviates the processing degree of difficulty, has improved the machining precision, under operating condition, receives great axial force when unusual, and the difficult axial float of retaining ring has improved life.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: the novel roller pin comprises a tripod 1, an inner ring 2, a roller pin 3, an outer ring 4, a retainer ring 5, a tool withdrawal groove 6 and an inner raceway 7.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in the figure, the tripod assembly of the bearing with the new structure mainly comprises a tripod 1 and a bearing, wherein the bearing is assembled on the tripod 1, the bearing consists of an outer ring 4, an inner ring 2, roller pins 3 and a retainer ring 5, the inner ring 2 is assembled in the outer ring 4, the plurality of roller pins 3 are positioned between the outer ring 4 and the inner ring 2, the retainer ring 5 is arranged at the upper end and the lower end of each roller pin 3, an inner raceway 7 and a tool withdrawal groove 6 are arranged on the inner wall of the outer ring 4, and a transition structure is arranged between the tool withdrawal groove 6 and the inner raceway 7. The retainer ring 5 is fixed in the tool withdrawal groove 6. The inner side of the tool withdrawal groove 6 is provided with a slope.
The utility model discloses improve bearing structure, improve the inside of outer lane 4 and add tool withdrawal groove structure for interior raceway, solved the deep groove processing difficulty of outer lane, the problem that the precision is low. Meanwhile, the problem that the bearing is blocked because the snap ring easily extends the outer ring deep groove to move when the bearing is abnormal under the condition of large axial force under the actual working condition is solved. The thickness of the outer ring 4 is reduced, and the design space is saved. The problem of the axial clearance undersize of the bearing that the easy drunkenness of snap ring leads to because of receiving axial force in the use of three ball pins is solved.
In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
