Description

Angular contact articulated bearing

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.

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.
