Abstract
The utility model relates to an integral-type screw oil seal which can be widely used for dynamic seal materials in rotary type of various machines, which is characterized in that two forms of sealing structure and multilevel sealing mechanism are used for integral rubbery materials which are sealed by the same oil seal, namely, the front and back parts of the non-major cutting edge openings of the oil seal are provided with spiral sealing sections. The utility model has the advantages of reasonable and compact structure, high reliability, strong sealing performance and high versatility.
Description
The utility model belongs to the sealing technique class
The present all kinds of machinery rotation type dynamic sealing materials of China have extensively adopted oil sealing, and are wherein general with lathe, automobile, tractor and diesel engine.
All kinds of now machinery control three spill tags are accurate strict, and the corresponding raising of oil sealing performance requirement is because existing general oil sealing cross-sectional configuration is general, so its sealing and reliable durable are faded in deficiency.
The purpose of this utility model is with mechanical type spiral seal principle, applies to the non-grease proofing main cutting edge place of oil sealing, improves the sealability and the reliability of oil sealing.
Fig. 1 is an integrated type spiral oil sealing cross-sectional configuration schematic representation, 1 is metal frame among the figure, 2 is the spring clip collar, 3 is rubber seal, 4 is the grease proofing main cutting edge of rubber seal, 5 do not have the grease proofing secondary cutting edge of spring clip collar for rubber seal, and 6 is spiral seal section before the grease proofing main cutting edge of rubber seal, and 7 is the grease proofing main cutting edge rear screw seal section of rubber seal.Fig. 2 launches schematic representation for spiral seal.
The utility model has adopted two spiral seal sections (6) (7) at interval before and after the grease proofing main cutting edge of oil sealing (4), overcome the mechanical type spiral seal in same installation dimension, technology and structural configuration are difficult to reach the deficiency of spiral seal requirement, have realized the effect performance of spiral seal.
Under preceding spiral seal section (6) and grease proofing main cutting edge (4) double action, strengthened the sealing of oil sealing.The main effect of grease proofing main cutting edge rear screw seal section (7) and grease proofing secondary cutting edge (5) has been to improve the reliability of oil sealing.During practice, rear screw seal section (7) is coated with an amount of molybdenum disulphide grease, is beneficial to durable in use.When the installation dimension possibility is limited, can locate or a spiral seal section of front or rear employing (6) or (7) at the whole non-grease proofing main cutting edge of rubber material of same oil sealing (4).
Characteristics of the present utility model are on the whole rubber material of same oil sealing, have used two kinds of sealing configuration forms and multi-level sealing mechanism.
The utility model compared with the prior art, it is reasonable to have a compact structure, sealability is strong, reliable durable is good, and is applied widely, the versatility advantages of higher.
Claims (1)
1, integrated type spiral oil sealing is a kind of rotary type dynamic sealing material that has used mechanical type spiral seal and two kinds of sealing configuration forms of oil sealing and multi-level sealing mechanism, of the present utility model being characterised in that, the whole non-grease proofing main cutting edge of rubber material of same oil sealing [4] has two spiral seal sections [6], [7] or only has a spiral seal section [6] or [7] before and after locating.
