Abstract

The invention discloses a four-point contact ball bearing. The four-point contact ball bearing comprises a bearing inner ring, rolling balls and a bearing outer ring; the rolling balls are arranged between the bearing inner ring and the bearing outer ring; the bearing inner ring and the bearing outer ring are provided with an annular raceway respectively; each annular raceway and each rolling ball are contacted at two points; an included angle B between connecting lines of two contact points and the center of the rolling balls is between 30 and 120 degrees; as two contact points are between each of the annular raceways of the bearing inner ring and the bearing outer ring and each rolling ball, and the included angle B between the two contact points is between 30 and 120 degrees, radial force stressed by each contact point of each rolling ball is smaller than the radial force stressed by a rolling ball of a conventional ball bearing when the bearing is stressed by the equal load; the bearing can also bear the axial force; and as gaps are formed between the rolling balls and the annular raceways, lube or grease lubricant is convenient to store, the lubricating condition of the rolling balls is improved, and the service life of the bearing can be improved.

Description

The ball bearing of 4 contacts
Technical field
The present invention relates to a kind of bearing, relate in particular to a kind of ball bearing.
Background technique
The ball bearing that generally uses all comprises bearing inner race at present, ball and bearing outer ring, ball is arranged between bearing inner race and the bearing outer ring, on bearing outer ring and bearing inner race, be equipped with ring raceway, the sectional shape of ring raceway is a circular arc, and the radius of this circular arc is greater than the radius of ball, the ball journal of this structure can only bear radial load, can not bear thrust load, and each ball and bearing outer ring and bearing inner race have only a point of contact respectively, the radially bearing capacity of bearing also is subjected to certain limitation, when the bearing physical dimension is restricted, and when bearing the ultimate bearing load greater than existing ball bearing, will reduce widely the working life of the bearing of this structure.Require the physical dimension of bearing little in other words on many special devices with specific (special) requirements, bearing capacity is big, thereby existing ball bearing can't satisfy the requirement of the said equipment.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of novel ball bearing, under equal specification, equal rotational velocity condition, this ball bearing can not only bear also bigger than the radial limits bearing load of existing ball bearing, and it can also bear thrust load, can improve the lubricating condition of ball simultaneously.
The problem to be solved in the present invention is the sectional shape that changes the ring raceway that existing bearing inner race and bearing outer ring be provided with, and optimizes the force-bearing situation of ball.
The present invention solves the problems referred to above by following technical solution:
The ball bearing of 4 contacts of the present invention comprises bearing inner race, ball and bearing outer ring, ball is arranged between bearing inner race and the bearing outer ring, on bearing inner race and bearing outer ring, be equipped with ring raceway, it is characterized in that: the sectional shape of the ring raceway on the described bearing inner race and the sectional shape of the ring raceway on the bearing outer ring are symmetrical, every raceway all has contact at 2 with each ball, and the angle β between the connecting line at two point of contact and ball center is 30 °-120 °.
As improvement of the present invention, the sectional shape of the described ring raceway two sections circular arcs that are symmetrical in the ball axis of serving as reasons are formed, and the radius R of this circular arc is greater than the radius r of ball, and described ball and above-mentioned two circular arcs are inscribe mutually.
As to further improvement of the present invention, the sectional shape of described ring raceway is one " V " type cross section tangent with described ball, and the bottom in " V " type cross section is connected by circular arc.
Owing between ring raceway on bearing inner race and the bearing outer ring and the ball two point of contact are arranged all, and angle β is between 30 °-120 ° between two point of contact, by as can be known to the force analysis of ball, this bearing is when being subjected to equal load, the radial force that each point of contact of ball is subjected to is all less than the suffered radial force of ball in the existing ball bearing, this bearing can also bear axial force, simultaneously owing between ball and ring raceway, have the slit, be convenient to store lubricant oil or lubricating grease, help improving the lubricating condition of ball, thereby can improve the working life of bearing.

Fig. 2 is the schematic representation of the sectional shape of ring raceway on the inside and outside circle of bearing for " V " shape;
1-bearing inner race among the figure; The 2-ball; The 3-bearing outer ring;
Embodiment
The ball bearing of 4 contacts of the present invention comprises bearing inner race 1, ball 2 and bearing outer ring 3, ball 2 is arranged between bearing inner race 1 and the bearing outer ring 3, on bearing inner race 1 and bearing outer ring 3, be equipped with ring raceway, the sectional shape of the ring raceway on the described bearing inner race and the sectional shape of the ring raceway on the bearing outer ring are symmetrical, every raceway all has contact at 2 with each ball, and the angle β between the connecting line at two point of contact and ball center is that the arbitrary value in 30 °-120 ° all can, β is 90 ° in this example, the sectional shape of described ring raceway is two sections circular arcs that are symmetrical in the ball axis, and the pass between the radius R of this circular arc and the radius r of ball is R=2.1r.
Certainly, the sectional shape of described ring raceway also can be designed to one " V " type cross section tangent with described ball, is connected by arc transition in the bottom in " V " type cross section.
