Abstract
The utility model discloses a kind of thin oil lubricant messenger bearing assembly, comprise messenger axle, messenger bearing chamber, messenger, messenger is contained in the lower end of messenger axle, and messenger axle top is positioned at messenger bearing chamber, and messenger bearing chamber upper flange is equipped with in the upper end of messenger bearing chamber; Bearing I connects with the upper end of messenger axle and the upper end of messenger bearing chamber respectively, and bearing II connects with the lower end of messenger bearing chamber and messenger axle lower end respectively; In the lower end of messenger bearing chamber, planar mechanical sealing mechanism is housed, planar mechanical sealing mechanism connects with messenger bearing chamber lower flange, between messenger bearing chamber lower flange and messenger, also lower seal is housed, the sealing tooth of lower seal matches with messenger bearing chamber lower flange, and lower seal is fixed on messenger axle.The utility model structure is simple, and it is firm to seal, and maintenance difficulty is little, and service cycle is short, long service life, and the expense in lubricating grease is only 2000-3000 unit/year.
Description
Technical field
The utility model relates to a kind of mechanical transmission, especially a kind of thin oil lubricant messenger bearing assembly device.
Background technique
Existing tumbling mill as centrifugal mill, Raymond mill, ultra-fine grinding mill, add grinder etc., the total journey of messenger of its inside and rugged environment under work, the total journey of messenger is at work owing to being subject to grinding roller and the factor such as bull ring, material collide, rub, hot air affects, the total Cheng Wendu of messenger is raised, lubricating grease liquefies very soon, although the lubricating grease liquefied very is soon conducive to bearing lubrication, but lubricating grease can leak into bearing chamber outside, the hot air produced also can overflow from the weakest outside framework oil seal, damages outside framework oil seal and causes lubricating grease consumption excessive.By user investigation 3216 grinding machines, within 1 year, lubricating grease consumes more than 10,000 yuan, and the dust being simultaneously less than 5 microns can enter into bearing chamber damage bearing under the effect of blower fan, causes maintenance expenses too high.In addition, lower swing overhang roll mill adopts plum blossom frame, and the compositions such as messenger bearing chamber, due to bearing chamber oil starvation in work, cause plum blossom frame to be out of shape.Therefore, develop a kind of structure simple, the messenger assembly that good sealing effect, practical cost are lower seems particularly necessary.
summary of the invention
The object of the invention is to overcome above-mentioned defect, design that a kind of structure is simple, the thin oil lubricant messenger bearing assembly device of good seal performance.
For achieving the above object, the utility model adopts following technical proposals: a kind of thin oil lubricant messenger bearing assembly, comprise messenger axle, messenger bearing chamber, messenger, messenger is contained in the lower end of messenger axle, messenger axle top is positioned at messenger bearing chamber, and messenger bearing chamber upper flange is equipped with in the upper end of messenger bearing chamber; Bearing I connects with the upper end of messenger axle and the upper end of messenger bearing chamber respectively, and bearing II connects with the lower end of messenger bearing chamber and messenger axle lower end respectively; In the lower end of messenger bearing chamber, planar mechanical sealing mechanism is housed, planar mechanical sealing mechanism connects with messenger bearing chamber lower flange, between messenger bearing chamber lower flange and messenger, also lower seal is housed, the sealing tooth of lower seal matches with messenger bearing chamber lower flange, and lower seal is fixed on messenger axle.
Described lower seal is labyrinth seal.
Messenger bearing chamber lower flange and the outer of lower seal connection part are with sealing ring, and sealing ring is connected with lower seal.
Described planar mechanical sealing machine is the sealing of S-C planar mechanical.
Adopt technique scheme, the utility model has following beneficial effect: (1) structure is simple, and it is firm to seal, and dust is difficult to enter, and maintenance difficulty is little, and service cycle is short.(2) few easy workout part, long service life.(3) power consumption is little, and efficiency is high.(4) cost is greatly reduced, and the expense of the total journey of thin oil lubricant messenger in lubricating grease is 2000-3000 unit/year.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. messenger bearing chamber upper flange 2. gas expansion chamber, 3. bearing I, 4. messenger bearing chamber, 5. mechanical planarization sealing, 6. messenger, 7. screw, 8. lower seal, 9. bearing II, 10. messenger axle, 11. messenger bearing chamber lower flanges, 12. sealing rings.
Embodiment
With reference to Fig. 1, a kind of thin oil lubricant messenger bearing assembly, comprise messenger axle 10, messenger bearing chamber 4, messenger 6, messenger is contained in the lower end of messenger axle, messenger axle top is positioned at messenger bearing chamber, messenger bearing chamber upper flange 1 is equipped with in the upper end of messenger bearing chamber, and one end three of messenger bearing chamber upper flange, bearing I, messenger axle forms gas expansion chamber 2.Bearing I 3 connects with the upper end of messenger axle and the upper end of messenger bearing chamber respectively, and bearing II 9 connects with the lower end of messenger bearing chamber and messenger axle bottom respectively; In the lower end of messenger bearing chamber, planar mechanical sealing mechanism 5 is housed, planar mechanical sealing mechanism is the sealing of S-C planar mechanical.Planar mechanical sealing mechanism connects with messenger bearing chamber lower flange 11, between messenger bearing chamber lower flange and messenger, lower seal 8 is also housed, and lower seal is labyrinth seal.The sealing tooth of lower seal matches with messenger bearing chamber lower flange, and lower seal screw 7 is fixed on messenger axle.Messenger bearing chamber lower flange and the outer of lower seal connection part are with sealing ring 12, and sealing ring is connected with lower seal.
Before using, the oil level upper limit of thin oil lubricant messenger bearing assembly charge of oil is the half of bearing I.During work, messenger bearing chamber lower flange 11 maintains static, sealing ring 12 and lower seal 8 are in company with messenger axle 10 and messenger 6 run-in synchronism, messenger bearing chamber lower flange 11, sealing ring 12 and labyrinth lower seal 8 form a set of mechanical seal, can effectively stop the dust of less than 5 microns and 5 microns to enter bearing chamber.
Claims (4)
