Abstract
The utility model belongs to the technical field of a bearing and provides a sealing mechanism of a bearing. The sealing mechanism of the bearing is provided with a sealing block (2), wherein the sealing block (2) is of an annular structure and is arranged at the position of a bonding face of a bearing outer ring (1) and a bearing inner ring (3); one end of a body (6) of the sealing block (2) is provided with two wing plates which stretch outwards and the wing plates comprise a wing plate I (4) and a wing plate II (5); a body (6) of the sealing block (2) is embedded into the bearing inner ring (3) or the bearing outer ring (1); the wing plate I (4) is located in a sealing groove between the bearing outer ring (1) and the bearing inner ring (3); and the wing plate II (5) is overlapped on the end face of the bearing inner ring (3) or the bearing outer ring (1). According to the sealing mechanism of the bearing disclosed by the utility model, the sealing degree and strength among the bearing inner ring, the bearing outer ring and the sealing block are improved and a mechanical transmission mechanism can be effectively operated for a long time.
Description
Technical field
The utility model belongs to technical field of bearings, relates generally to a kind of sealing mechanism of bearing.
Background technique
Bearing is the supporting member in the mechanical transmission mechanism, is used for determining running shaft and other part relative movement position, and its quality directly influences the service behaviour of mechanical complete machine, drives the motion of associated mechanisms by the running of bearing.Bearing turns round in various environment, the rugged environment of more windy and dusty operating mode particularly, and foreign matter is easy to enter raceway by the slit between the inside and outside circle of bearing, makes that bearing is on-stream to damage.In order to address the above problem, the omission that sealing mechanism prevents bearing internal lubrication fat need be set, avoid the bearing use of under the oil starvation state, turning round, but that sealing mechanism of the prior art exists all is poorly sealed, the problem of easy leakage of oil.In addition, the sealing block in the sealing mechanism easily comes off and sealing block twines accessory structure easily, causes sealing mechanism to damage.
The model utility content
For solving the problems of the technologies described above, the purpose of this utility model is the sealing mechanism that proposes a kind of bearing.
The utility model adopts following technological scheme for finishing the foregoing invention purpose:
A kind of sealing mechanism of bearing, described sealing mechanism has sealing block, and described sealing block is loop configuration, and is arranged on the junction plane position of bearing outer ring and bearing inner race; Body one end of described sealing block has two outwardly directed wing plates: wing plate I, wing plate II; The body of described sealing block embeds in bearing inner race or the bearing outer ring, in the seal groove of described wing plate I between bearing outer ring and bearing inner race; Described wing plate II rides on the end face of bearing inner race or bearing outer ring.
A kind of sealing mechanism of bearing has projection on the described body of sealing block, has the groove that cooperates for projection on the body on described bearing inner race or the bearing outer ring.
A kind of sealing mechanism of bearing, the body of described wing plate I, wing plate II and the sealing block structure that is formed in one
The sealing mechanism of a kind of bearing that the utility model proposes, the structure that adopts bearing inner race, bearing outer ring and sealing block convex-concave to fasten, improve seal degree and intensity between bearing inner race, bearing outer ring and the sealing block, guaranteed the long-time effectively operation of mechanical transmission mechanism.

Fig. 2 is the structural representation of sealing block in the utility model.
Among the figure: 1, bearing outer ring, 2, sealing block, 3, bearing inner race, 4, the wing plate I, 5, the wing plate II, 6, body.
Embodiment
With specific embodiment the utility model is illustrated by reference to the accompanying drawings:
As shown in Figure 1, a kind of sealing mechanism of bearing, described sealing mechanism has sealing block 2, and described sealing block 2 is loop configuration, and is arranged on the junction plane position of bearing outer ring 1 and bearing inner race 3; In conjunction with Fig. 2, body 6 one ends of described sealing block 2 have two outwardly directed wing plates: wing plate I 4, wing plate II 5; The body 6 of described sealing block 2 embeds in bearing inner race 3 or the bearing outer ring 1, in the seal groove of described wing plate I 4 between bearing outer ring 1 and bearing inner race 3; Described wing plate II 5 rides on the end face of bearing inner race 3 or bearing outer ring 1, plays seal action; Have projection 7 on the described body 6, have the groove that cooperates for projection 7 on the body on described bearing inner race 3 or the bearing outer ring 1; The body 6 of described wing plate I 4, wing plate II 5 and the sealing block structure that is formed in one.
Claims (3)
1. the sealing mechanism of a bearing, described sealing mechanism has sealing block (2), and described sealing block (2) is loop configuration, and is arranged on the junction plane position of bearing outer ring (1) and bearing inner race (3); It is characterized in that: body (6) one ends of described sealing block (2) have two outwardly directed wing plates: wing plate I (4), wing plate II (5); The body (6) of described sealing block (2) embeds in bearing inner race (3) or the bearing outer ring (1), and described wing plate I (4) is positioned at the seal groove between bearing outer ring (1) and the bearing inner race (3); Described wing plate II (5) rides on the end face of bearing inner race (3) or bearing outer ring (1).
2. the sealing mechanism of a kind of bearing according to claim 1, it is characterized in that: have projection (7) on the described body (6) of sealing block (2), have the groove that cooperates for projection (7) on the body on described bearing inner race (3) or the bearing outer ring (1).
