Abstract
The utility model discloses a bearing lubrication and sealing structure. A left pressing cover and a right pressing cover are respectively installed in an inner hole of a bearing shell and fixed by a spring gasket and a bolt; a bearing is fixed between the left pressing cover and the right pressing cover through an outer ring of the bearing, an inner ring of the bearing is installed on a fan shaft, a framework oil seal is arranged between the right pressing cover and the fan shaft, a felt oil seal is installed in a groove in the left pressing cover, an inner hole of the felt oil seal is installed on a shaft neck of the fan shaft, a bleeder screw is installed in a threaded hole over the bearing shell and a threaded hole over the right pressing cover, and a through hole used for controlling the oil level is formed in the portion below the bearing shell and the right pressing cover. The bearing lubrication and sealing structure has the advantages that the bearing lubrication and sealing structure is reasonable in structural design, accurate in oil adding amount, and when a machine is operated, the heat dissipating effect is good.
Description
Technical field
The utility model relates to the partial structurtes of engineering goods, especially bearing lubrication and sealing configuration.
Background technique
Bearing is the parts that support the axial workpiece rotation, and along with the raising of axle rotating speed, the lubricated and sealing of bearing is particularly important.
Summary of the invention
The purpose of this utility model is to provide the new structure of a kind of bearing lubrication and sealing, can discharge in time the run up heat that produces can reasonably to bearing, add lubricant oil in time of bearing.
The utility model solves the technological scheme that its technical problem adopts: described bearing lubrication and sealing configuration comprise bleed screw, cartridge housing, left gland, bearing, fan shaft, felt oil seal, outside framework oil seal and right gland, left gland and right gland are contained in respectively in the endoporus of cartridge housing and use spring washer, bolt is fixed, bearing is fixed between left gland and right gland by the outer ring of bearing, the inner ring of bearing is contained on fan shaft, outside framework oil seal is contained between right gland and fan shaft, felt oil seal is contained in the groove of left gland, the endoporus of felt oil seal is contained on the axle journal of fan shaft, bleed screw is contained in the screw directly over cartridge housing and right gland, there is the through hole of controlling pasta the below of cartridge housing and right gland.
This bearing lubrication with the advantage of sealing configuration is: bearing lubrication and design of Sealing Structure are reasonable, and the quantity of refueling is accurate, during machine run, and good heat dissipation effect.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Accompanying drawing is the erection drawing of the lubricated and sealing configuration of bearing.
Fig. 1 is the B-B place sectional drawing of Fig. 2.
Fig. 2 is the A-A place sectional drawing of Fig. 1.
1. housings in figure, 2. bleed screw, 3. cartridge housing, 4. left gland, 5. bearing, 6. fan shaft, 7. felt oil seal, 8. outside framework oil seal, 9. right gland.
Embodiment
Accompanying drawing is bearing lubrication and the sealing configuration on the high speed winds arbor of jet-air rice polisher blower fan, and it is contained on the housing (1) of jet-air rice polisher blower fan by cartridge housing (3).Bearing lubrication and sealing configuration are by bleed screw (2), cartridge housing (3), left gland (4), bearing (5), fan shaft (6), felt oil seal (7), and outside framework oil seal (8) and right gland (9) form.Left gland (4) is contained in the endoporus of cartridge housing (3) with spring washer, is bolted to the left side of cartridge housing (3).Felt oil seal (7) is contained in the groove of left gland (4), and the endoporus of felt oil seal (7) is contained on the axle journal on the left side of fan shaft (6), is sealed.Right gland (9) is contained in the endoporus of cartridge housing (3) with spring washer, is bolted to the right of cartridge housing (3).Because the wind wheel of blower fan is installed on the right of fan shaft (6), it is very unfavorable to bearing (5) that the gas of conveying contains dust.So adopt outside framework oil seal (8) sealing.Outside framework oil seal (8) is contained between right gland (9) and fan shaft (6).Outside framework oil seal (8) can produce heat with the fan shaft (6) of High Rotation Speed, therefore adopt bleed screw (2) venting.Bleed screw (2) is contained in the screw directly over cartridge housing (3) and right gland (9).On the axis of bleed screw (2), have aperture to communicate with the horizontal hole of top, hot gas just can be discharged from this hole.There is the through hole of controlling pasta the below of cartridge housing (3) and right gland (9).Unloading bleed screw (2) can refuel from its installation screw.When added oil reaches the liquid level of regulation, unnecessary oil can show from the hole of the below of cartridge housing (3) and right gland (9), just stops refueling.
Claims (1)
1. a bearing lubrication and sealing configuration, comprise bleed screw, cartridge housing, left gland, bearing, fan shaft, felt oil seal, outside framework oil seal and right gland, it is characterized in that: left gland and right gland are contained in respectively in the endoporus of cartridge housing and use spring washer, bolt is fixed, bearing is fixed between left gland and right gland by the outer ring of bearing, the inner ring of bearing is contained on fan shaft, outside framework oil seal is contained between right gland and fan shaft, felt oil seal is contained in the groove of left gland, the endoporus of felt oil seal is contained on the axle journal of fan shaft, bleed screw is contained in the screw directly over cartridge housing and right gland, there is the through hole of controlling pasta the below of cartridge housing and right gland.
