Abstract
The utility model discloses a sealed thrust ball bearing. The sealed thrust ball bearing comprises a shaft ring (1), a seat ring (2) and a ball (3), wherein the ball (3) is movably arranged between the shaft ring (1) and the seat ring (2); the sealed thrust ball bearing is characterized in that the bottom surface of the shaft ring (1) is provided with a downwards raised circular-ring shaped convex ring (11); the upper surface of the seat ring (2) is provided with a downwards sunken circular-ring shaped concave ring (21); the circular-ring shaped convex ring (11) and the circular-ring shaped concave ring (21) are folded from top to bottom and are adaptive with each other; and a hole cavity for containing lubricating grease is formed in a gap between the circular-ring shaped convex ring (11) and the circular-ring shaped concave ring (21). Compared with the prior art, the sealed thrust ball bearing has the advantages that the lubricating grease is well contained in the hole cavity formed in the gap between the circular-ring shaped convex ring and the circular-ring shaped concave ring, thus effectively preventing the lubricating grease from leaking outsides, achieving long-time working stability and flexibility of the bearing, and effectively prolonging the service life of the bearing. Moreover, the bearing is very convenient to manufacture and low in production cost.
Description
Technical field
The utility model relates to a kind of Production of bearing technical field, especially refers to a kind of sealed type thrust ball bearing.
Background technique
Thrust ball bearing is widely used in life and the industry equipment, but because the sealing of common thrust ball bearing is poor, cause bearing to lack lubricating grease and can't work, existing a kind of patent No. is 200920249689.6 and is called that the Chinese utility model patent of " a kind of hermetically sealed thrust ball bearing of dismantled and assembled separation " discloses a kind of structure, its structure is by frame and be installed in seat ring in the frame, steel ball, retainer and blowout patche consist of, frame is semiclosed U-shaped shape, its bottom is provided with boss, and the end of seat ring and blowout patche is provided with concentric half-round race and steel ball is set and retainer.Blowout patche is installed in the top that frame does not seal the U-shaped end, its axial end portion is provided with the interior shoulder of spill of support, the internal diameter of the internal diameter＞frame of shoulder in this spill also is provided with on blowout patche for the tapped hole of blowout patche mounting or dismounting and oil hole and inner seal ring and the exterior seal ring that is used for bearing lubrication simultaneously.This model utility has reliable, lubricated abundant, the simple load and unload function of sealing, can guarantee the usage requirement under the bad working environments, and purposes is more extensive.But the shortcoming of this model utility is, structure is still partially complicated, and processing is trouble also, and oil hole is easily by foreign matters from being blocked.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of to design ingenious, simple in structure, easy to process and can effectively prevent a kind of sealing thrust ball bearing that lubricant grease leaks outside in the bearing for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technological scheme that adopts: this sealing thrust ball bearing, include blowout patche, seat ring and ball, described ball places between blowout patche and the seat ring movably, it is characterized in that: described blowout patche bottom surface is provided with the ring flange collar to lower convexity, and the middle part of described ring flange collar is provided with the toroidal cavity suitable with ball; Be provided with above the described seat ring to the recessed circle of the ring of lower recess, be provided with the ring cavity suitable with ball at the middle part, bottom surface of the recessed circle of described ring; Described ring flange collar is involutory and mutually fit in up and down with the recessed circle of ring, described ball can rollably be arranged between toroidal cavity and the ring cavity, and the gap between described ring flange collar and the recessed circle of ring forms the vestibule of accommodating lubricating grease.
As improvement, described blowout patche and described ring flange collar can be preferably the disposable overall structure that is made.
As improvement, described seat ring and the recessed circle of described ring are to be preferably the disposable overall structure that is made.
As improvement, also can be provided with between described blowout patche and the seat ring for the retainer of placing ball.
As improvement, be evenly distributed with 6～30 manholes on the described retainer, the quantity of described ball is corresponding with through hole, and certainly, the quantity of manhole can be more or less, specifically can decide by design.
Compared with prior art, the utility model adopts described blowout patche to be provided with the ring flange collar, described seat ring is provided with the recessed circle of ring, the ring flange collar is involutory and mutually fit in up and down with the recessed circle of ring, and the gap between the recessed circle of ring flange collar and ring forms the vestibule of accommodating lubricating grease.The advantage of this structure is, lubricating grease can be placed in the vestibule of the gap formation between ring flange collar and the recessed circle of ring well, thereby effectively prevent leaking outside of lubricating grease, realize stability and the sensitivity of bearing length time service, effectively prolonged the working life of bearing, and the blowout patche of this bearing and described ring flange collar are the disposable overall structure that is made of metallic material or plastic materials, described seat ring and the recessed circle of described ring are the disposable overall structure that is made of metallic material, therefore making is also very convenient, and cost of production is also lower.
