Abstract
A kind of angular contact articulated bearing, it is related to the angular contact articulated bearing of the technical field of angular contact articulated bearing, more particularly to heavy-duty low-speed occasion.The utility model includes bearing outer ring and inner ring, and the working surface of the outer ring is Internal Spherical Surface, and the working surface of inner ring is spherical outside surface;The spherical outside surface of inner ring is smooth spherical outside surface, and several more evenly distributed axial oil-ways are processed in bearing outer ring Internal Spherical Surface;The shaped bases of the oil-way are circular arc, from an end face to other end of outer ring.The utility model is applied to oil lubrication or grease lubrication operating mode, improve in particular the lubrication state on bearing high-mechanic regional work surface, can form more uniform oil film, so as to reduce the abrasion of bearing, improves the service life of bearing.
Description
Technical field
It the utility model is related to the angular contact of the technical field of angular contact articulated bearing, more particularly to heavy-duty low-speed occasion
Oscillating bearing.
Background technology
In existing angular contact articulated bearing, bearing is made up of inner ring, outer ring.The spherical outside surface of inner ring and the Internal Spherical Surface of outer ring
Form friction pair.The working surface friction pair is steel to steel pattern.Generally there are two to intersect profit in the Internal Spherical Surface of outer ring
Oil groove.Generally have two traffic circle oil-ways in the Internal Spherical Surface of outer ring, it is big for service load, it is desirable to lubrication state compared with
Good occasion, the structure oil reserve or depot fat amount are less, and lubrication state is poor.
A kind of non-maintaining angular contact articulated bearing disclosed in Chinese patent CN202560816U, in the Internal Spherical Surface of bearing outer ring
A plurality of uniform positive and negative skewed crossing oil-way is designed with, positive and negative oil groove is crossed as 76~85 °, utilizes form cutter, dividing engine
Structure and special tooling work in-process are process in the heart.The positive and negative oil-way complex designing, processing efficiency are relatively low.
The content of the invention
The purpose of this utility model is to provide a kind of corner connection simple in construction, high lubricating effect in view of the shortcomings of the prior art
Touch oscillating bearing.
To reach above-mentioned purpose, its technical solution is:The bearing includes inner ring and outer ring.In the interior ball of bearing outer ring
Face be designed with it is a plurality of be shaped as circular arc in circumferential uniform oil-way, the oil-way, from an end face of outer ring to
Other end.
Above-mentioned a kind of angular contact articulated bearing, wherein the uniform lubricating oil groove bar number in the Internal Spherical Surface of outer ring is 6~12
Bar.
Above-mentioned a kind of angular contact articulated bearing, wherein the cross section of oil-way uniform in the Internal Spherical Surface of outer ring is circular arc
Shape.
Above-mentioned a kind of angular contact articulated bearing, wherein the cross section of oil-way uniform in the Internal Spherical Surface of outer ring is triangle
Shape, its drift angle bottom are circular arc.
The oil-way is formed using shaping dies and special tooling time processing.Oil-way can be used for storing lubricating oil
Fat.
The utility model has positive effect relative to prior art:The circumferential uniform a plurality of lubricating oil in the inner ring face of outer ring
Groove can store more lubricating oil.Suitable for grease lubrication operating mode, the lubrication state of bearing spherical surface is improved, so as to reduce bearing
Abrasion, improve the service life of bearing.

Fig. 2 is the structure chart of angular contact bearing outer ring(Fig. 2 a)And B-B direction sectional view(Fig. 2 b).
Fig. 3 is the schematic diagram of circular section oil-way.
Fig. 4 is the schematic diagram of triangular cross section oil-way.
In figure:1- outer rings, 2- inner rings, the oil-way of 3- outer rings Internal Spherical Surface.
Embodiment
Embodiment:As shown in Figure 1 to Figure 2, a kind of angular contact articulated bearing of the utility model includes:Bearing outer ring 1 and interior
The working surface for enclosing 2. outer rings 1 is Internal Spherical Surface, and the working surface of inner ring 2 is spherical outside surface.The spherical outside surface of inner ring 2 is smooth
Spherical outside surface, can have more lubricating oil between working surface at work for increase bearing, be processed in the Internal Spherical Surface of bearing outer ring 1
Multiple tracks is along the circumferentially uniform axial lubrication groove 12 of sphere, and the oil-way is shaped as circular arc, one from outer ring
End face to other end.During work, Internal and external cycle contact surface should add lubricating oil or lubricating grease, 12 uniform axial direction profits on outer ring
Oil groove 3 can store more sufficient lubricant medium, and more uniform oil film is formed on Internal and external cycle contact surface.
As shown in figure 3, the cross section of the utility model oil-way uniform in the Internal Spherical Surface of outer ring is circular arc, the circle
Arc radius is R.
As shown in figure 4, the cross section of the utility model oil-way uniform in the Internal Spherical Surface of outer ring is triangle, angle
For θ, its drift angle bottom is circular arc, and the circular arc radius is R.
