The purpose of this utility model is for the above-mentioned problems in the prior art, the roller bearing units of provide a kind of high lubricating effect, being convenient to maintain.
The purpose of this utility model can realize by following technical proposal: a kind of roller bearing units, comprise outer ring, inner ring and the retainer between outer ring and inner ring, be embedded with steel ball in described retainer, be provided with at least one lip ring between described outer ring and inner ring, the inboard, outer ring is provided with annular seal groove, the outer rim of described Sealing embeds in described seal groove, the inner edge of Sealing contacts at the inner ring outer circumferential face, it is characterized in that, described outer ring offers oil hole, and described oil hole makes the outer circumferential face of outer ring be connected with the inboard, outer ring.
This roller bearing units is by the setting of Sealing and seal groove, good airproof performance can be applicable to the harsh and unforgiving environments such as mud, the setting of oil hole in addition, make this roller bearing units after installation, need not dismounting, just can by oil hole to retainer, steel ball place's interpolation lubricating grease, maintain easy to operate, retainer, the good greasy property of steel ball place's maintenance, rub little, noise is low, and has extended working life.
In above-mentioned a kind of roller bearing units, described oil hole is inclined hole.Be arranged so that like this lubricating grease can the spill-over phenomenon can not occur along smooth-going retainer, the steel ball place of entering of the oil hole that tilts, and adds lubricating grease smooth.
In above-mentioned a kind of roller bearing units, the inner ring of described Sealing has seal lip one, seal lip two and the seal lip three that all contacts at the inner ring outer circumferential face.
Seal lip one is positioned at the outside, seal lip two is between seal lip one and the seal lip three in the inboard, this roller bearing units seals by seal lip one, seal lip two and seal lip three, play the effect at the three seals outpost of the tax office, good sealing effect, this roller bearing units can be applicable to the harsh working environments such as mud, and is applied widely.
In above-mentioned a kind of roller bearing units, the outer rim of described Sealing has circular fold, and described circular fold is close to groove side wall.The outer rim that is arranged so that Sealing of circular fold and seal groove close contact, good sealing effect.
In above-mentioned a kind of roller bearing units, described Sealing has two and bilateral symmetry to be distributed in bearing two ends.The setting of two Sealings can prevent that the foreign material such as muddy water from entering into axial inner, reduces the bearing inter deterioration, has extended working life.
In above-mentioned a kind of roller bearing units, described Sealing is made by the fine oil-resistant rubber material of fourth and steel plate.Sealing is wear-resisting like this, long service life.
In above-mentioned a kind of roller bearing units, the outer circumferential face of described outer ring has annular knurl.Annular knurl is that the fine recesses of strip consists of, and being provided with to be beneficial to of annular knurl installed the location, avoids the outer ring slippage to occur.
Compared with prior art, this roller bearing units is by the setting of oil hole, make this roller bearing units after installation, need not dismounting, just can be by oil hole to retainer, steel ball place's interpolation lubricating grease, maintain easy to operately, retainer, steel ball place keeps good greasy property, rubs little, noise is low, and extended working life, and the good sealing effect of this roller bearing units, can be applicable to the harsh working environments such as mud, applied widely, the setting of annular knurl in addition avoids the outer ring slippage to occur, facilitates the installation location of this roller bearing units.
