Abstract
The utility model discloses an antifriction bearing lubricating structure in pairs, it is changeing epaxial antifriction bearing in pairs to include to install through the bearing frame, be provided with the disc in the pivot, the antifriction bearing who is close to the disc is the outboard bearing, and the antifriction bearing who keeps away from the disc is the inboard bearing. Be equipped with lubricated oil duct on the bearing frame, the import of lubricated oil duct lies in disc place side and rotates the lubricating oil that is splashed in order to accept the disc, and lubricating oil says that the export lies in the inboard bearing side with the inboard bearing that leads lubricating oil. When the disc got rid of to the bearing frame oil all around, partial lubricating oil flowed into the inboard bearing through this lubricated oil duct to make the both sides bearing all realize the sufficient lubrication.
Description
Technical field
The utility model is related to bearing arrangement and in particular to a kind of paired rolling bearing lubrication structure, belongs to bearing lubrication
Technical field.
Background technology
In order to realize more preferably more stably rotating, the occasion of paired rolling bearing is used to get more and more at present.Bearing runs
When need to lubricate, current bearing lubrication mode is usually disc mode and lubricates (as shown in Figure 1), i.e. close bearing in rotating shaft
Position is provided with disc, real with the lubricating oil entrance bearing movable pair of the driven splashing of rotating shaft quick rotation using disc
Existing good lubrication.But in pairs there are following problems in rolling bearing lubrication at present: because two rolling bearings have one all the time near getting rid of
Oil ring, another deviates from disc, near bearing (referred to as outboard bearing) sufficient lubrication of disc, away from the axle of disc
Holding that (referred to as inboard bearing) be often in cannot sufficient lubrication.
Utility model content
For existing paired Lubrication Mode for Rolling Bearing above shortcomings, the purpose of this utility model is to provide one kind
Rolling bearing lubrication structure in pairs, this lubrication system two rolling bearing can realize good lubrication.
For solving above-mentioned technical problem, the utility model employs technical scheme below:
Rolling bearing lubrication structure in pairs, including the paired rolling bearing being arranged on by bearing block in rotating shaft；In rotating shaft
On be provided with disc；It is outboard bearing near the rolling bearing of disc, the rolling bearing away from disc is inboard bearing；
Oil leab is provided with bearing block, the import of oil leab is located at disc place side to accept what disc rotation was splashed
Lubricating oil, oil leab outlet is located at inboard bearing side so that lubricating oil is guided inboard bearing.
Further, described bearing block is made up of top chock and step, and step upper surface is more than upper bearing (metal)
Seat lower surface area is not so that when both fasten, step upper surface inboard portion is covered by top chock lower surface to be formed
Platform, described oil leab arranges on the platform, and the import of oil leab tilts to be beneficial to lubricating oil to outlet gradually downward
Flowing.
Further, described oil leab by oil flow direction by the axial oil transportation road being sequentially communicated, radially defeated
Oil duct and axial oil road are constituted, and axial oil transportation road front end constitutes oil leab import, and axial oil road end constitutes lubricating oil
Road exports.
Described oil leab is the twice being arranged symmetrically along shaft axis.
Compared with prior art, the utility model has the advantages that
The utility model arranges oil leab on bearing block, when disc gets rid of oil to bearing block surrounding, partial lubrication
Oil flows into inboard bearing by this oil leab, so that sufficient lubrication all realized by two side bearings.
Brief description
Fig. 1-existing paired rolling bearing lubrication structural representation.
Fig. 2-the utility model paired rolling bearing lubrication structural representation.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in detail.
Referring to Fig. 2, can be seen that the utility model paired rolling bearing lubrication structure from figure, including by bearing block 1
It is arranged on the paired rolling bearing in rotating shaft 2；Disc 3 is provided with rotating shaft 2；Rolling bearing near disc 3 is outer
Side bearing 4, the rolling bearing away from disc is inboard bearing 5.In order that inboard bearing 5 also can carry out sufficient lubrication,
Bearing block 1 is provided with oil leab 6, and the import of oil leab is located at disc place side to accept what disc rotation was splashed
Lubricating oil, oil leab outlet is located at inboard bearing side so that lubricating oil is guided inboard bearing, therefore passes through oil leab, can
The lubricating oil that disc is splashed guides inboard bearing, so that sufficient lubrication all realized by two side bearings.
Described oil leab 6 is the twice being arranged symmetrically along shaft axis, is arranged symmetrically twice abundant beneficial to inboard bearing
Lubrication.
Further, described bearing block is made up of top chock and step, usual upper and lower axle bearing end face coupling with
Fasten completely.For ease of arrange oil leab, in this structure step upper surface be more than top chock lower surface area so that
When both fasten, step upper surface inboard portion is not covered to form platform by top chock lower surface, described lubricating oil
Road just arranges on the platform, and the import of oil leab tilts to be beneficial to the flowing of lubricating oil to outlet gradually downward.
Described oil leab is by oil flow direction by axial oil transportation road, radial direction oil transportation road and the Axial-running Out being sequentially communicated
Oil duct is constituted, and each section of junction seamlessly transits.Axial oil transportation road front end constitutes oil leab import, and axial oil road end is constituted
Oil leab exports.
Finally illustrate, above-described embodiment is merely to illustrate the technical solution of the utility model and unrestricted, although ginseng
According to preferred embodiment, the utility model is described in detail, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent, the objective without deviating from technical solutions of the utility model and model
Enclose, it all should be covered in the middle of right of the present utility model.
