Abstract
The utility model provides a labyrinth seal structure of a main shaft bearing of a double-geared roller crusher in surface mine or underground coal mine industry. The structure consists of a movable labyrinth ring, a sealing part, a fixed labyrinth ring and a shaft cover, wherein the movable labyrinth ring and the fixed labyrinth ring form labyrinth seal, the movable labyrinth ring rotates along a main shaft, the fixed labyrinth ring is fixed on a bearing pedestal by a fastener, the sealing part is arranged between the fixed labyrinth ring and the shaft cover, the shaft cover is in interference fit connection with the main shaft (7) and rotates along with the main shaft (7), an outlet of the bearing labyrinth seal is additionally provided with a V-shaped seal ring, the V-shaped seal ring is respectively and closely contacted with sides A and B of a ring-shaped groove of the movable labyrinth ring, an elastic seal lip of the V-shaped seal ring is closely contacted with a bottom surface C of the ring-shaped groove of the fixed labyrinth ring, the V-shaped seal ring rotates along with the movable labyrinth ring, and the elastic seal lip of the V-shaped seal ring and the bottom surface C of the ring-shaped groove of the fixed labyrinth ring form a seal surface. According to the seal structure which consists of the V-shaped seal ring, the labyrinth seal, the sealing part and the shaft cover, the labyrinth seal internally forms a seal space to prevent dust from entering and lubricating grease from outflowing (note: sequence 7 is not labeled in drawings). The outlet of the bearing labyrinth seal is provided with the V-shaped seal ring to prevent lubricating grease in the labyrinth seal from losing and a mass of lubricating grease from entering into a crushing cavity, and according to the V-shaped seal ring, a certain pressure is formed in the labyrinth ring to prevent dust from entering, so that the seal effect of the labyrinth ring can be enhanced.
Description
Technical field
The utility model relates to the labyrinth seal structure of a kind of double-geared roller crusher main shaft bearing in surface mine or downhole coal mine industry.
Background technique
Double-geared roller crusher is a kind of disintegrating apparatus that bulk materials is broken into piece material, usually uses in mine or downhole coal mine in the open, and due to work under bad environment, dust particale is more, therefore bearing needs good sealing state.In prior art, the bearing seal state often has two kinds of situations, and a kind of is that labyrinth seal causes dust to enter for shortage of oil, and bearing is even damaged in impact, and then directly affects working efficiency and the working life of disintegrating apparatus; Another kind is a large amount of excessive situations of lubricant grease that cause because fuel feeding is sufficient, and leakage of oil seriously can cause fire peril when being used for broken coal.Both of these case once occurred on the disintegrating apparatus of home and abroad, and problem is difficult to solve.Therefore, the labyrinth seal structure of a kind of double-geared roller crusher main shaft bearing of development is the new problem that needs to be resolved hurrily always.
The model utility content
The purpose of this utility model is to provide a kind of labyrinth seal structure of double-geared roller crusher main shaft bearing, above-mentioned deficiency for prior art, this labyrinth seal structure guarantees that bearing is in good sealed environment, simultaneously grease does not occur again excessive in a large number, effectively economizes on the grease amount.
the purpose of this utility model is achieved in that a kind of labyrinth seal structure of double-geared roller crusher main shaft bearing is by moving labyrinth ring, Sealing, quiet labyrinth ring, axle sleeve forms, moving labyrinth ring and quiet labyrinth ring form labyrinth seal, moving labyrinth ring rotates with main shaft, quiet labyrinth ring is fixed on bearing support by fastening piece, Sealing is between quiet labyrinth ring and axle sleeve, axle sleeve is connected with the main shaft interference fit, and rotate with main shaft, set up a V-shaped seal ring in the bearing labyrinth outlet port, the annular groove A face of V-shaped seal ring and moving labyrinth ring and B face be close contact respectively, the annular groove bottom surface C close contact of the elastic packing lip of V-shaped seal ring and quiet labyrinth ring, the servo-actuated labyrinth ring rotation of V-shaped seal ring, the annular groove bottom surface C of the elastic packing lip of V-shaped seal ring and quiet labyrinth ring forms sealing surfaces simultaneously, like this by V-shaped seal ring, labyrinth seal, Sealing and axle sleeve form the labyrinth seal structure of main shaft bearing, this sealing configuration makes and forms enclosed space in labyrinth seal, stop dust to enter, and prevent that lubricating grease is excessive.
Main points of the present utility model are its structure and working principle.its working principle is, moving labyrinth ring and quiet labyrinth ring form labyrinth seal, moving labyrinth ring rotates with main shaft, axle sleeve is connected with the main shaft interference fit, and rotate with main shaft, the annular groove A face of V-shaped seal ring and moving labyrinth ring and B face be close contact respectively, the annular groove bottom surface C close contact of the elastic packing lip of V-shaped seal ring and quiet labyrinth ring, the servo-actuated labyrinth ring rotation of V-shaped seal ring, the annular groove bottom surface C of the elastic packing lip of V-shaped seal ring and quiet labyrinth ring forms sealing surfaces simultaneously, like this by V-shaped seal ring, labyrinth seal, Sealing and axle sleeve form the labyrinth seal structure of main shaft bearing, this sealing configuration makes and forms enclosed space in labyrinth seal, labyrinth seal produces certain pressure after injecting grease, stop dust to enter, and prevent that lubricating grease is excessive.
A kind of labyrinth seal structure of double-geared roller crusher main shaft bearing compared with prior art, have in the labyrinth seal outlet port V-shaped seal ring is set, can stop lubricating grease loss in labyrinth seal, prevent that a large amount of lubricating grease from entering crusher chamber, and this place's V-shaped seal ring can make and form certain pressure in labyrinth seal, stop entering of dust, strengthen the advantages such as sealing effect of labyrinth seal, will be widely used in surface mine or downhole coal mine industry.
