Abstract
The invention discloses a low-loss high-efficiency lubricating torsion bar support assembly which comprises a torsion bar support and is characterized by further comprising a sealing plug, a first needle bearing, a support sleeve and a second needle bearing which are arranged in the torsion bar support, sequentially and closely arranged from the inside to the outside and with oil channels or oil through grooves which are communicated in one way formed and an end cover arranged on the outer end portion of the torsion bar support. The torsion bar support assembly has the advantage that lubricating oil is injected into the needle bearings through the one-way oil guide channels, and a good lubricating effect is achieved on the needle bearings. In the lubricating oil replacement process, new lubricating oil extrudes out most lubricating oil with impurities and needing replacing through the one-way lubricating oil channels, abrasion of impurities particles contained by the lubricating oil to the needle bearings under the high speed rotating work condition is reduced, and the service life of the needle bearings is prolonged.

In continuously tracked vehicle behavioral system, need to be lubricated torsion bar supporting construction, the lubricating method of employing is mainly at present: by a plurality of tiny pod in bearing carrier ring, in bearing, inject lubricating oil.Because lubricated means are single, so can there are following shortcomings:
The first, lubricating oil easily flow into bearing from the little pod of internal pressure, and the less even oil mass of lubricants capacity flowing in the larger pod of internal pressure is zero, cause lubricated localization, lubricant effect is poor, easily causes bearing because of partial lubrication deficiency unstable wear.
Although second, pod quantity is more, general groove depth is more shallow, and the lubricating oil oil reserve that enters into groove is less, and under high-speed and high-temperature state, lubricating oil is easily because gasification, seepage etc. are former thereby minimizing, causes bearing to reduce the life-span because of lack of lubrication.
Three, pod does not form single oil duct, more during oil change, with the lubricating oil of a period of time be difficult to be extruded by fresh oil, the impurity that produces of causing coming off in mechanical operation process is mixed in in lubricating oil after a while and continues to be deposited in bearing, has aggravated the wearing and tearing of bearing in high-speed operation process.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of high lubricating effect, the torsion bar supporting component to the little low damage of wear-out of a bearing, high-efficiency lubricating.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of low damage, the torsion bar supporting component of high-efficiency lubricating, comprise: torsion bar anchor, it is characterized in that, also comprise: be arranged on the inside of aforementioned torsion bar anchor and from inner outwards compact arranged sealing plug successively, the first needle bearing, support sleeve, the second needle bearing, and be arranged on the outer end of aforementioned torsion bar anchor and be bolted the end cap of installation with aforementioned torsion bar anchor, the inboard of aforementioned end cap, on the outer ring of the second needle bearing, on support sleeve, on the outer ring of the first needle bearing, be formed with respectively end cap oil duct, the second bearing oil duct, cross oil groove and clutch shaft bearing oil duct, aforementioned end cap oil duct, the second bearing oil duct, cross oil groove and clutch shaft bearing oil duct and be communicated with successively the unidirectional Oil Guide passage of formation.
The torsion bar supporting component of aforesaid low damage, high-efficiency lubricating, is characterized in that, aforementioned the second needle bearing is the bearing with biserial needle roller.
The torsion bar supporting component of aforesaid low damage, high-efficiency lubricating, is characterized in that, between aforementioned end cap and the second needle bearing, is provided with baffle ring, is formed with the oil guide groove that is communicated with end cap oil duct and the second bearing oil duct on aforementioned baffle ring.
The torsion bar supporting component of aforesaid low damage, high-efficiency lubricating, is characterized in that, between aforementioned end cap and baffle ring, is provided with oil sealing.
The torsion bar supporting component of aforesaid low damage, high-efficiency lubricating, is characterized in that, also comprises: with the oil hole of aforementioned Oil Guide passage, oiling conduit, the oil out duct that oil outlet is communicated with.
Usefulness of the present invention is: by unidirectional Oil Guide passage, lubricating oil is injected in needle bearing, needle bearing is played to good lubricating effect, and in the process of oil change more, new lubricating oil is replaced major part through single-way lubricating oil duct lubricating oil with the needs of impurity is extruded, thereby the wearing and tearing of the contained impurity particle of lubricating oil to needle bearing under High Rotation Speed operating mode have been reduced, the service life of having improved needle bearing.
Accompanying drawing explanation
Fig. 1 is the section-drawing of a specific embodiment of the torsion bar supporting component of low damage of the present invention, high-efficiency lubricating.
The implication of Reference numeral in figure: 1-end cap, 2-oil sealing, 3-baffle ring, 4-the second needle bearing, 5-support sleeve, 6-the first needle bearing, 7-sealing plug, 8-torsion bar anchor, 9-end cap oil duct, 10-the second bearing oil duct, 11-clutch shaft bearing oil duct, 12-crosses oil groove.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
With reference to Fig. 1, low damage of the present invention, the torsion bar supporting component of high-efficiency lubricating, comprise: torsion bar anchor 8, sealing plug 7, the first needle bearing 6, support sleeve 5, the second needle bearing 4 and end cap 1, sealing plug 7, the first needle bearing 6, support sleeve 5 and the second needle bearing 4 are all arranged on the inside of torsion bar anchor 8 and from inner outwards close-packed arrays successively, end cap 1 is arranged on the outer end of torsion bar anchor 8 and is bolted installation with torsion bar anchor 8, thereby by sealing plug 7, the first needle bearing 6, support sleeve 5 and the second needle bearing 4 are locked in the inside of torsion bar anchor 8.Wherein, the inboard of end cap 1 is formed with on the outer ring of end cap oil duct 9, the second needle bearing 4 and is formed with on the outer ring that was formed with oil groove 12, the first needle bearing 6 on the second bearing oil duct 10, support sleeve 5 and is formed with clutch shaft bearing oil duct 11, end cap oil duct 9, the second bearing oil duct 10, crosses oil groove 12 and clutch shaft bearing oil duct 11 is communicated with the unidirectional Oil Guide passage of formation successively.Lubricating oil injects torsion bar supporting component from the oil hole of Oil Guide passage, and in the process through Oil Guide passage, lubricating oil is lubricated the first needle bearing 6 and the second needle bearing 4, finally from oil outlet, flows out.Due in the process of oil change more, new lubricating oil is replaced major part through single-way lubricating oil duct lubricating oil with the needs of impurity has been extruded, thereby reduced the wearing and tearing of the impurity particle in lubricating oil to needle bearing under High Rotation Speed operating mode, and then the service life of having improved needle bearing.
