Abstract
The utility model relates to a vehicle air conditioner compressor electric magnetic clutch bear sealing element, comprising a glue body, an outer ring, an inner ring and a sealing ring, when equipping the outer ring of the sealing ring with an interference is matched with an outer dent and outer ring belt of the vehicle air conditioner compressor electric magnetic clutch bear, a vertical main lip of the sealing ring is vertically contacted with a line on the outer ring belt of the inner ring dent, and axial main lip of the sealing ring is axially contacted with a outer ring belt wall of the inner ring dent. The utility model vertically and axially has sealing performance, a sealing side lip of the sealing ring can also block greases thrown out by a centrifugal effort from the bear rotating to form a labyrinth type sealing structure with high sealing performance, flexibly rotate and effectively block the grease leakage of the vehicle air conditioner compressor electric magnetic clutch bear, and can also block outer invasion of dust and water, which has the advantages of a reasonable structure, good performance of dust proof and water proof, a good effect of anti grease leakage, a smaller friction torque and long using life.
Description
[technical field]
The utility model relates to a kind of structure of seal arrangement, especially relates to a kind of high performance electromagnetic clutch of automobile air conditioner compressor and holds sealing unit.
[background technique]
At present, electromagnetic clutch of automobile air conditioner compressor holds that sealing unit can not satisfy high rotating speed that electromagnetic clutch of automobile air conditioner compressor holds, high temperature resistant, waterproof and dustproof, anti-lubricating grease is revealed and the requirement of low running torque.
[model utility content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of rational in infrastructure, easy for installation, high temperature resistant, waterproof and dustproof, anti-lubricating grease is revealed and be suitable for high rotating speed and the electromagnetic clutch of automobile air conditioner compressor of the high performance requirements that running torque is low holds sealing unit.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of electromagnetic clutch of automobile air conditioner compressor holds sealing unit, comprise colloid, outer ring, inner ring and seal ring, the outer endless belt interference fit of seal ring is in the electromagnetic clutch of automobile air conditioner compressor bearing outer-ring raceway groove outside endless belt during assembling, the radially main lip of seal ring radially contacts with endless belt shelves limit, the bear inner ring grooved railway outside, and the axial main lip of seal ring axially contacts with bear inner ring grooved railway outside endless belt wall.
Described seal ring is skeleton rubber three lip seal circles, the seal ring skeleton be provided with the radially main lip that is " people " font structure, axial main lip and secondary lip interior week.
The radially main lip of described seal ring radially slides with endless belt shelves limit, the bear inner ring grooved railway outside and contacts.
The axial main lip of described seal ring endwisely slips with bear inner ring grooved railway outside endless belt wall and contacts.
The beneficial effects of the utility model are: of the present utility model radially, axially all have a sealability, the sealing pair lip of seal ring can also stop the lubricating grease that throws away because of bearing rotation generation centrifugal force, form the sealing configuration of mazy type high sealing performance, guarantee that sealing is reliable, rotation stops electromagnetic clutch of automobile air conditioner compressor to hold leaking of lubricating grease flexibly and effectively, and can stop the intrusion of outside dirt and water; Have rational in infrastructure, dustproof, water-proof performance is good, the grease-proof leakage effect is good, friction torque is less and the advantage of long service life, satisfies the requirement that the high sealing performance electromagnetic clutch of automobile air conditioner compressor holds.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-seal ring skeleton, the 2-colloid, the outer endless belt of 3-seal ring, 4-outer ring raceway outside endless belt, 5-seal ring radial seal master lip, endless belt shelves limit, the 6-bear inner ring grooved railway outside, 7-bear inner ring grooved railway outside endless belt, 8-seal ring axial seal master lip, 9-bear inner ring grooved railway outside endless belt wall, the secondary lip of 10-seal ring, 11-outer ring seal groove, 12-inner ring seal groove.
[embodiment]
Below in conjunction with drawings and Examples the utility model is further specified.Referring to Fig. 1, a kind of electromagnetic clutch of automobile air conditioner compressor holds sealing unit, comprise colloid 2, the outer ring, inner ring and seal ring, in inner ring, be provided with inner ring seal groove 12, in the outer ring, be provided with outer ring seal groove 11, the outer endless belt 3 band interference fit of seal ring are in electromagnetic clutch of automobile air conditioner compressor bearing outer-ring raceway groove outside endless belt 4 during assembling, the radial seal master lip 5 of seal ring " people " font structure radially contacts with endless belt shelves limit, the bear inner ring grooved railway outside 6, the axial seal master lip 8 of seal ring " people " font axially contacts with bear inner ring grooved railway outside endless belt wall 9, so radially, sealability is axially all arranged, the secondary lip 10 of seal ring can also stop the lubricating grease that throws away because of bearing rotation generation centrifugal force, therefore, form the sealing configuration of mazy type high sealing performance; Have rational in infrastructure, dustproof, water-proof performance is good, the grease-proof leakage effect is good, friction torque is less, satisfies the requirement that the high sealing performance electromagnetic clutch of automobile air conditioner compressor holds.Bear inner ring grooved railway outside endless belt 7 is positioned at inner ring seal groove 12.
Seal ring is skeleton rubber three lip seal circles, outer endless belt 3 interference fit of seal ring are in electromagnetic clutch of automobile air conditioner compressor bearing outer-ring raceway groove outside endless belt 4, the radially main lip 5 that seal ring is " people " font that is provided with in interior week at seal ring skeleton 1, axial main lip 8 and secondary lip 10, the radially main lip 5 of seal ring radially contacts slip with endless belt shelves limit, the bear inner ring grooved railway outside 6, axial main lip 8 axially contacts slip with bear inner ring grooved railway outside endless belt wall 9, the secondary lip 10 of seal ring can also stop the lubricating grease that throws away because of bearing rotation generation centrifugal force, can guarantee that sealing is reliable, rotation stops electromagnetic clutch of automobile air conditioner compressor to hold leaking of lubricating grease flexibly and effectively, and can stop the intrusion of outside dirt and water.
