Through offered the lubricated oil duct of slant on the lateral wall of bearing, can realize real -time oiling, do not need to dismantle the bearing again to get off to carry on oiling, labour saving and time saving, through being provided with sealed pad and sealing up the lid, when the oiling is accomplished, will seal up to fill up and seal up to cover and install in the seal groove, prevent that lubrication oil from coming out from the cavity midstream of bearing.
Description
Technical field
This utility model relates to technical field of bearings, particularly relates to a kind of modified model rolling bearing.
Background technology
Bearing is for determining rotary shaft and other part relative motion positions, plays supporting or guide effect
Parts.The major function of bearing is supporting rotating shaft or other movable body, guides and rotates or mobile
Move and bear the load being transmitted to by axle or parts on shaft.Bearing be the present age plant equipment in not
Can or lack base parts and components, national economy every profession and trade application quite varied, its precision, performance,
Life and reliability plays conclusive effect to the precision of main frame, performance, life and reliability.Press
The difference of motor element frictional property, bearing can be divided into rolling bearing and the big class of sliding bearing two.Wherein
Rolling bearing is typically made up of outer ring, inner ring, rolling element and retainer four part, be strictly speaking by
Outer ring, inner ring, rolling element, retainer, sealing, lubricating oil six big part composition.In simple terms, only
Outer ring to be possessed, inner ring, rolling element just may be defined as rolling bearing.By the shape of rolling element, rolling
Dynamic bearing is divided into ball bearing and the big class of roller bearing two.
According to a kind of bearing that Chinese Patent Application No. is 201320265239.2 announcements, including bearing outside
Ring and bearing inner ring, be provided with ball between described outer race and bearing inner ring, and this bearing inner ring is along footpath
To being provided with at least one lubrication channel, bearing inner ring is provided with at least one lubrication hole vertically, this lubrication hole and profit
Slideway is connected, and described ball is hollow-core construction.The bearing of this structure by offering lubrication channel,
Although its lubricant effect can be improved, but fluid needs to inject from the inwall of bearing inner race, when
When bearing inner race is arranged on power transmission shaft, power transmission shaft can block lubrication channel, when needs oiling again,
Need to get off bearing removal, be so not easy to secondary oiling.
Utility model content
This utility model is in order to overcome deficiency of the prior art, it is provided that a kind of modified model rolling bearing.
This utility model is to be achieved through the following technical solutions:
A kind of modified model rolling bearing, including in bearing outer ring, bearing inner race, bearing outer ring and bearing
Circle cooperates, and is provided with multiple ball between bearing outer ring and bearing inner race, and ball sleeve is keeping
On frame, adjacent ball is linked together by retainer, and described bearing inner race offers for pacifying
The ball grooves of dress ball, offers seal groove, described close on a sidewall of described bearing inner race
Oblique lubricating oil duct is offered to the cavity direction of bearing on the sidewall of sealing groove, and in described seal groove
Sealing gasket is installed, one end contact of described sealing gasket on the sidewall of described seal groove, sealing gasket
The other end and close closure contacts, seal lid and be arranged in seal groove.
As optimal technical scheme of the present utility model, one end diameter of described oblique lubricating oil duct is big,
Other end diameter is little, and one end that diameter is big is oil-in, and one end that diameter is little is oil-out.
As optimal technical scheme of the present utility model, this bearing also includes left side dust-blocking ring and right side gear
Konisphere, in the left side cavity that described left side dust-blocking ring is arranged between bearing outer ring and bearing inner race, institute
State in the right side cavity that right side dust-blocking ring is arranged between bearing outer ring and bearing inner race.
As optimal technical scheme of the present utility model, described sealing gasket is elastic sealing gasket.
Compared with prior art, the beneficial effects of the utility model are: this utility model is by axle
Oblique lubricating oil duct is offered, it is possible to realize real-time oiling, it is not necessary to torn open by bearing again on the sidewall held
Unload down and carry out oiling, time saving and energy saving；It is provided by sealing gasket and seals lid, when oiling completes,
Sealing gasket and sealing lid are arranged in seal groove, prevent lubricating oil from flowing out from the cavity of bearing.
