Description
Technical Field
The utility model belongs to the oil blanket field, concretely relates to novel oil blanket.
Background
The oil seal is a seal for the lubricating oil, which separates the components to be lubricated from the driven components, avoiding leakage of the lubricating oil. At present, the oil blanket on the market, inside spring all are indisputable, and the operating mode medium of a lot of installation use positions lets the spring rust very easily, and the rust water of spring can corrode the oil blanket after rustting, makes the oil blanket life-span reduce, causes the condition of oil leak, and the inside lip of oil blanket is a lip more, damages the oil blanket easily in the installation, and in use reduces product life or directly causes sealed unsatisfactory, the direct condition of leaking oil. The oil blanket dust guard mouth part is single, and inside the dust can enter the oil blanket from the dust guard mouth of oil blanket, the frictional force of increase oil blanket and axle, produced high temperature, thereby the unsatisfactory life and the quality that influence the oil blanket of dustproof effect.
SUMMERY OF THE UTILITY MODEL
The not enough to prior art, the utility model provides a novel oil blanket, for realizing above-mentioned purpose, the utility model provides a following technical scheme: a novel oil seal comprises a sealing body, a framework and a spring; the sealing body comprises an inner ring and an outer ring; the framework is arranged in the sealing body and penetrates through the whole sealing body outer ring; a spring groove is formed in a gap between the inner ring and the outer ring of the sealing body, and the spring is clamped in the spring groove; the edge of the outer ring of the seal body is provided with a lip, and a dustproof opening is arranged above the lip.
Preferably, the dustproof openings comprise a first dustproof opening and a second dustproof opening; the first dustproof opening is arranged outside the sealing body, and the second dustproof opening is arranged above the lip opening and inside the sealing body.
Preferably, the number of the lip openings is at least 2.
Preferably, the number of the springs is 2, and the springs are made of 304 stainless steel.
Preferably, the sealing body is an annular body consisting of an inner ring and an outer ring.
Advantageous effects
Compared with the prior art, the utility model following beneficial effect possesses: the utility model discloses a novel oil blanket through the inside clearance that sets up double spring and come between sealed axle and the oil blanket that sets up of seal, keeps sealed elasticity, and the setting of lips and two dust ports has prolonged the life of oil blanket, guarantees product quality.
Drawings
For ease of illustration, the invention is described in detail by the following detailed description and accompanying drawings.
FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a sectional view of the present invention;
fig. 3 is a schematic diagram of a dual spring position.
In the figure: 1-sealing body, 1-1-inner ring, 1-2-outer ring, 2-framework, 3-spring, 4-spring groove, 5-lip, 6-dustproof opening, 6-1-first dustproof opening, and 6-2-second dustproof opening.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Fig. 1-3 show a novel oil seal, which comprises a sealing body 1, a framework 2 and a spring 3; the sealing body 1 comprises an inner ring 1-1 and an outer ring 1-2; the framework 2 is arranged in the sealing body 1 and penetrates through the outer ring of the whole sealing body 1; spring grooves 4 are formed in gaps between the inner ring 1-1 and the outer ring 1-2 of the sealing body 1, the two spring grooves 4 are distributed adjacently, and the springs 3 are annular and clamped in the spring grooves 4; a lip 5 is arranged at the edge of the outer ring 1-2 of the sealing body 1; and a dustproof opening 6 is arranged above the lip 5.
Preferably, the dustproof openings 6 comprise a first dustproof opening 6-1 and a second dustproof opening 6-2, the first dustproof opening 6-1 is arranged outside the sealing body 1, the second dustproof opening 6-2 is arranged above the lip 5 and inside the sealing body 1, and the first dustproof opening 6-1 is mainly used for preventing granular objects such as dust and the like from entering the sealing body 1; the second dustproof opening 6-2 is mainly used for secondary protection, and once dust enters the first dustproof opening 6-1, the second dustproof opening 6-2 prevents the dust from contacting the shaft and the lip 5; the sealing body 1 is sequentially provided with a first dustproof opening 6-1, a second dustproof opening 6-2 and a lip opening 5 from outside to inside.
Preferably, 3 quantity of springs is 2, and spring 3 is 304 stainless steel, avoids spring 3 to rust the corrosion oil blanket of rust water after rustting, shortens the oil blanket life-span and causes the condition of oil leak.
The utility model discloses a setting up the clearance between sealed axle that the biliquid spring can be better and the oil blanket inside the seal, avoiding keeping sealed elasticity because the high temperature that frictional force produced makes the not hard up condition in lip limit after the long-time work of product. The 304 stainless steel material avoids the spring rusting and shortens the service life of the oil seal to cause the oil leakage. The utility model discloses a lip and the design of two dustproof mouths have prolonged the life of oil blanket, guarantee product quality.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
