The utility model discloses a novel composite bearing seal structure includes the bearing, set up at axle sleeve, the bearing cover who sets up in the axle sleeve outside on bearing right side, set up sealed oil guide groove on axle sleeve and bearing cover contact surface, set up and be used for guaranteeing oil -recovery tank that the oil return is unblocked on bearing cover, set up at the inboard yx type sealing washer of bearing cover and set up the polytetrafluoroethylene cover between axle sleeve and yx type sealing washer, sealed oil guide groove and oil -recovery tank are linked together. Sealed oil guide groove is including sealed oil guide groove of axle sleeve who sets up at the axle sleeve lateral wall and the gland seal oil guide groove who sets up at the bearing cover inside wall, sealed oil guide groove of axle sleeve and gland seal oil guide groove are incompletely corresponding. The service life of sealed effect has guaranteed that the oil circuit is unobstructed, and it has the oil gallery to open on bearing cover simultaneously, guarantees that the oil return is unblocked, and the utilization ratio of oil and bearing temperature also reduce during than before oil blanket seal structure to some extent, thus the bearing is prolonged.
This utility model relates to a kind of NEW TYPE OF COMPOSITE bearing seal structure.
In pump industry, the seal style of bearing generally uses contact type sealing structure or non-contacting sealing structure to reach the purpose sealed.Contact seal many employings outside framework oil seal structure, non-contacting seal many employings labyrinth seal structure.
Contact type sealing structure, bearing gland is provided with outside framework oil seal, and this kind of sealing means design is simple, and the vibration of machine and the bias of main shaft are had certain adaptability.But it is unreliable to run, long-term existence Leakage, and maintenance difficult；Reflecting according to scene, within the most several days, will change an oil sealing, 2-3 month sometimes, the longest not over 1 year, not only maintenance difficult, costly, and frequently leakage of oil also results in deleterious effect to environment, quality own to pump in after-sale service.
Non-contacting sealing structure, forms the least gap between revolving part and fixture, produces the biggest energy loss through throttling, makes oil head greatly decline, make oil be difficult to seepage, it is achieved seal.If but when running on-the-spot volume read-out slightly larger, lubricating oil will along gap leakage, and if site environment severe, various dusts and serosity also can enter fuel tank along gap, and then cause the situation such as lubricant pollution, bearing damage occur.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of NEW TYPE OF COMPOSITE bearing seal structure.
The technical solution of the utility model is:
This utility model include bearing, be arranged on the axle sleeve on the right side of bearing, be arranged on the bearing gland outside axle sleeve, oil groove is drawn in the sealing that is arranged on axle sleeve and bearing gland contact surface, be arranged on bearing gland for ensureing the unimpeded oil-recovery tank of oil return, being arranged on the Yx RunddichtringO inside bearing gland and the politef set being arranged between axle sleeve and Yx RunddichtringO；Described sealing is drawn oil groove and is connected with oil-recovery tank.
Sealing described in the utility model is drawn oil groove and is included being arranged on the sleeve sealing of axle sleeve lateral wall and draw oil groove and be arranged on the gland of bearing gland medial wall and seal and draw oil groove, and described sleeve sealing draws oil groove and gland seals that to draw oil groove the most corresponding.
Yx RunddichtringO described in the utility model is externally provided with water retaining disk.
Water retaining disk described in the utility model is embedded on bearing gland.
It is matched in clearance between Yx RunddichtringO described in the utility model and politef set.
Good effect of the present utility model is: the gap 1, made full use of between revolving part axle sleeve and fixture bearing gland seals, and for a small amount of lubricating oil oozed out by gap, axle sleeve and bearing gland all offer a few road and draws oil groove and the most corresponding, ensure that oil circuit is unobstructed, on bearing gland, have spill port, it is ensured that oil return is unimpeded simultaneously.2, leaking for lubricating oil and dust etc. enters the situation of fuel tank, added a kind of compound seal, this sealing is added politef set by axle Yx RunddichtringO and forms.This sealing makes full use of the self lubricity of politef, and controls fit tolerance well, when making Yx RunddichtringO and politef set rotate against, frictional force is the least, both ensure that using effect, and turn avoid frictional force and cross the damage of ambassador's sealing ring, improve service life.3, owing to using oil enveloping structure, time, after oil sealing damages, interstage sleeve and bearing gland also can damage therewith therewith, must change together, costly during replacing.Sealing great advantage after improvement is that the life-span is long, if really needing to change, only changing Yx RunddichtringO, it is not necessary to more shifting sleeve and bearing gland, being greatly saved time and workload, reduce cost.4, using after compound seal, reduce the friction loss brought due to oil sealing, shaft power has declined, and bearing temperature also than former oil seal structure time decrease, thus improve bearing service life.5, by the improvement of this sealing structure, substantially increasing the operational reliability of pump product, reduce cost and the maintenance rate of product, at the scene after application, effect is fine, meets onsite application demand, improves the competitiveness of product in market.

Detailed description of the invention
This utility model is described in further detail with embodiment below in conjunction with accompanying drawing:
A kind of NEW TYPE OF COMPOSITE bearing seal structure as Figure 1-3 include bearing 1, be arranged on the axle sleeve 2 on the right side of bearing 1, be arranged on the bearing gland 3 outside axle sleeve 2, oil groove 4 is drawn in the sealing that is arranged on axle sleeve 2 and bearing gland 3 contact surface, be arranged on bearing gland 3 for ensureing the unimpeded oil-recovery tank 5 of oil return, being arranged on the Yx RunddichtringO 6 inside bearing gland 3 and the politef set 7 being arranged between axle sleeve 2 and Yx RunddichtringO 6；Described sealing is drawn oil groove 4 and is connected with oil-recovery tank 5.Described sealing is drawn oil groove 4 and is included being arranged on the sleeve sealing of axle sleeve 2 lateral wall and draw oil groove 4-1 and be arranged on the gland of bearing gland 3 medial wall and seal and draw oil groove 4-2, described sleeve sealing draws oil groove 4-1 and gland and seals that to draw oil groove 4-2 the most corresponding, and being crisscross arranged and existing partly overlaps.Improve sealing effectiveness, it is ensured that oil circuit is unobstructed, simultaneously on bearing gland, have spill port, it is ensured that oil return is unimpeded, improve the utilization rate of oil and bearing temperature also than former oil seal structure time decrease, thus improve bearing service life.
Described Yx RunddichtringO 6 is externally provided with water retaining disk 8；Described water retaining disk 8 is embedded on bearing gland 3, further increases sealing effectiveness.
It is matched in clearance between described Yx RunddichtringO 6 and politef set 7, take full advantage of the self lubricity of politef, and control fit tolerance well, when making Yx RunddichtringO and politef set rotate against, frictional force is the least, both ensure that using effect, and turn avoid frictional force and cross the damage of ambassador's sealing ring, improve service life.
Above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in previous embodiment still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model embodiment technical scheme.
