Description
Technical field
This utility model relates to field of bearings, especially relates to a kind of taper roll bearing with self-lubricating effect.
Background technology
Bearing is the more conventional fixed member in engineering machinery, the most of a great variety, is widely used.Along with society
The fast development that meeting is economic, market is increasing to the demand of bearing, it is desirable to more and more higher.Plain bearing includes that inner ring is with outer
Circle, and it is located at the ball in the middle of inner ring and outer ring.The taper roll bearing used in early days, because cost is high, has
People proposes oiliness bearing, and general oiliness bearing is to make with copper material, has countless said minuscule hole, nationality said minuscule hole inside it
Capillarity, can be therefore named for oiliness bearing by oil containing in the inner.And when a rotating shaft rotates on its hollow bulb, again can nationality
Oil contained in oiliness bearing is caused rotary shaft to play lubrication by capillarity, and its cost is relatively low, by extensively profit
With, the oiliness bearing used at present, the oil in its oil storage portion can flow rapidly to oil-containing axle along with the rotation of rotating shaft along gap
The other end held also is easy to throw away and lose under operating, not only result in waste, and the oil of storage in oiliness bearing
Loss is totally so that the life-span of oiliness bearing greatly reduces, and therefore, how to increase the oil content in oil storage portion, prevents the mistake of oil
Fast run off and how to improve life-span of oiliness bearing become for focus of attention, so existing oiliness bearing is structurally
Need overall improvement, to meet the demand of existing market.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, it is provided that a kind of circle with self-lubricating effect
Taper roller bearing, it is possible to increase the lubricant effect of bearing, reduces number of times and the frequency of bearing oil addition, and then improves bearing
Serviceability and service life.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
A kind of taper roll bearing with self-lubricating effect, including inner ring and outer ring, and be arranged on described inner ring and
Tapered roller retainer between outer ring, it is characterised in that: form axis hole on described inner ring, the lateral surface of described inner ring is formed
Upper groove and lower groove, be provided with between groove and described lower groove on described be arranged in order from top to bottom the first draw-in groove,
Two draw-in grooves and the 3rd draw-in groove.
This utility model is done further preferably, described first draw-in groove, described second draw-in groove, described 3rd draw-in groove are filled
Graphite.
Doing this utility model further preferably, described first draw-in groove, described 3rd draw-in groove fill graphite respectively, and described
Two draw-in grooves are dead slot.
Doing this utility model further preferably, described upper groove is that annular is arranged, and on described, the bottom of groove is formed
Cavity volume.
This utility model is done further preferably, also include that sealed eyelet, described sealed eyelet are buckled on described
Gap is formed between groove upper end, and described cavity volume.
Doing this utility model further preferably, described lower groove is that annular is arranged, and is provided with in the outside of described lower groove
Annular support ring, described in support ring and offset bottom taper roller.
This utility model is done further preferably, also include that steel wire ring, the outside of described steel wire ring are provided with cotton layer, described steel
Silk latch closure is in described lower groove.
Compared with prior art this utility model is reached to provide the benefit that:
Inner ring in this utility model taper roll bearing, it is formed axis hole, the lateral surface of described inner ring is formed
Groove and lower groove, be provided with between groove and described lower groove on described be arranged in order from top to bottom the first draw-in groove, second
Draw-in groove and the 3rd draw-in groove, this utility model realizes depositing certain lubricating oil up and down by upper groove and lower groove, and
And can prevent internal lubrication oil from leaking outside, simultaneously shape in lower groove as desired to arrange sealed eyelet on above groove
The ring bottom just with taper roller that supports become offsets, and forms certain sealing, it is also possible to prevent lubricating oil from leaking outside.And first
Draw-in groove, the second draw-in groove and the 3rd draw-in groove can meet effect and the purpose of self-lubricating as desired to arrange.So this practicality is new
Type can improve the lubricant effect of bearing, prevents internal lubrication oil from leaking outside, and also is able to reduce the secondary of bearing oil addition simultaneously
Number and frequency, and then improve serviceability and the service life of bearing.
It follows that this utility model can solve the problem that problems of the prior art, it is possible to increase the lubrication effect of bearing
Really, reduce number of times and the frequency of bearing oil addition, and then improve serviceability and the service life of bearing.
Accompanying drawing explanation
Accompanying drawing is used for providing being further appreciated by of the present utility model, and constitutes a part for description, with this practicality
Novel embodiment is used for explaining this utility model together, is not intended that restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, being not used to limit this utility model.
Embodiment: as it is shown in figure 1, this utility model provides a kind of taper roll bearing with self-lubricating effect, including
Inner ring 1 and outer ring 2, and it is arranged on the tapered roller retainer 3 between described inner ring 1 and outer ring 2, it is characterised in that: described
Forming axis hole 4 on inner ring 1, the lateral surface of described inner ring 1 is formed groove 5 and lower groove 6, on described, groove 5 is with described
