Abstract
The utility model is related to taper roll bearings, are made of bearing inner race, bearing outer ring, bearing roller, the first oil-way, the second oil-way and third oil-way；First oil-way, the second oil-way and third oil-way are sequentially located on bearing inner race, and first oil-way, the second oil-way and third oil-way provide lubricating oil by bearing outer ring to bearing roller.Taper roll bearing described in the utility model, using the first oil-way, the second oil-way and third lubricating oil, the friction between bearing roller and bearing inner race can effectively be reduced, so that the working efficiency of taper roll bearing greatly improves, work, which is lost, to be substantially reduced.Taper roll bearing described in the utility model, it is simple in structure, it is easy to use, it is very convenient to be needed in actual production.
Description
Technical field
The utility model is related to field of bearings, relate in particular to a kind of taper roll bearing.
Background technology
Taper roll bearing belongs to divergence type bearing, and the inside and outside circle of bearing all has tapered raceway.The class bearing is by being filled
The columns of roller is divided into the different structural shape such as single-row, biserial and four-row tapered roller bearing.Single-row tapered roller bearing can
To bear radial load and single direction axial load.When bearing bears radial load, it will generate an axial thrust load, institute
To be balanced when needing another that can bear the bearing of negative direction axial force.Single-row tapered roller bearing bears axial load
Ability depend on contact angle, i.e. outer ring raceway angle, angle is bigger, and axial load ability is also bigger.In taper roll bearing
Dosage it is most be single-row tapered roller bearing.In general, the coning angle of single-row tapered roller bearing outer ring raceway 10 ° ~ 19 ° it
Between, the synergy of axial load and radial load can be born simultaneously.Cone angle is bigger, and the ability for bearing axial load is also cured
Greatly.The bearing of big coning angle, postposition code name add B, and for cone angle between 25 ° ~ 29 °, it can bear larger axial load.In addition,
Single-row tapered roller bearing can adjust the size of clearance during the installation process.
Utility model content
The purpose of this utility model is to provide a kind of taper roll bearings for reducing friction, extending the service life.
In order to solve the above technical problems, the purpose of this utility model is achieved through the following technical solutions：
Taper roll bearing, by bearing inner race, bearing outer ring, bearing roller, the first oil-way, the second oil-way and
Third oil-way forms；
The bearing roller is installed between bearing inner race and bearing outer ring；First oil-way, the second lubricating oil
Slot and third oil-way are sequentially located on bearing inner race, first oil-way, the second oil-way and third lubricating oil
Slot provides lubricating oil by bearing outer ring to bearing roller.
First oil-way and third oil-way are located at the both ends cusp of bearing inner race, second lubricating oil
Slot is located in the direct contacting surface of length of bearing inner race.
First oil-way, the second oil-way and third oil-way can retain lubricating oil.
The depth of second oil-way is 20-50 microns.
First oil-way and third oil-way are due in the cusp area for wearing bearing inner race both ends the most serious
The first oil-way and third oil-way are added in domain herein, can effectively reduce between bearing roller and bearing inner race
Friction
Second oil-way contacts maximum region due to being in bearing inner race, increases by the second oil-way herein, can
Help to reduce the friction between bearing roller and bearing inner race.
The beneficial effects of the utility model are：
Taper roll bearing described in the utility model is lubricated using the first oil-way, the second oil-way and third
Oil can effectively reduce the friction between bearing roller and bearing inner race, so that the working efficiency of taper roll bearing
It greatly improves, work, which is lost, to be substantially reduced.Taper roll bearing described in the utility model, it is simple in structure, it is easy to use, very
It is convenient to actual production needs.

Embodiment.
As shown in Figure 1, taper roll bearing, by bearing inner race 1, bearing outer ring 2, bearing roller 3, the first oil-way 4,
Second oil-way 5 and third oil-way 6 form；
The bearing roller 3 is installed between bearing inner race 1 and bearing outer ring 2；First oil-way 4, second moistens
Oil groove 5 and third oil-way 6 are sequentially located on bearing inner race 1, first oil-way 4, the second oil-way 5 and
Three oil-ways 6 provide lubricating oil by bearing outer ring 2 to bearing roller 3.
First oil-way 4 and third oil-way 6 are located at the both ends cusp of bearing inner race 1, second profit
Oil groove 5 is located in the direct contacting surface of length of bearing inner race 1.
First oil-way 4, the second oil-way 5 and third oil-way 6 can retain lubricating oil.
The depth of second oil-way 5 is 20-50 microns.
The preferable specific implementation mode of the above, only the utility model, these specific implementation modes are all based on this
Different realization methods under utility model general idea, and the scope of protection of the utility model is not limited thereto, it is any ripe
Know those skilled in the art within the technical scope disclosed by the utility model, the change or replacement that can be readily occurred in, all
It should cover and be within the protection scope of the utility model.
