Abstract
The utility model provides a four-point contact thrust bearing comprising an inner ring, an outer ring and steel balls. The utility model is characterized in that both the inner ring and the outer ring are composed of half outer rings and half inner rings; both sides of each of the half inner rings are provided with inner ball tracks, and both sides of each of the half outer rings are provided with outer ball tracks; the steel balls installed in the inner and outer ball tracks contact the inner and the outer ball tracks at four points, and the contact angles are 45 DEG. Because the steel balls contact the inner and the outer ball tracks at four points, the utility model has the advantages of capability of bearing radial force, shock resistance, long service life and high reliability.
Description
The utility model belongs to thrust ball bearing, the helicoid hydraulic motor thrust ball bearing of saying so in more detail.
Former helicoid hydraulic motor bearing is to be in series by many covers single direction thrust ball bearing and a plurality of packing ring.The inside and outside raceway of its bearing is one section continuous circular arc, and steel ball is at 2 with inside and outside raceway and contacts that wrapping angle is a zero degree.The bearing of this kind form of the composition exists and can only bear axial force, can not bearing radial force, and shortcoming such as the ability that withstands shocks, life-span are short, and reliability is low.In addition, the bearing of this structure all acquires a certain degree of difficulty at aspects such as assembling, maintenance and fault diagnosises, is difficult to satisfy the technical requirements that digs a directional well.
The purpose of this utility model is for solving above-mentioned existing problems, a kind of four point contact thrust ball bearings are provided, and it has bears axially and composite force radially, shock-resistant, long service life, characteristics such as reliability height.
In order to achieve the above object, the utility model comprises outer ring, inner ring and steel ball, it is characterized in that outer ring and inner ring all are to be made of several structures identical semi outer rings and the assembling of half inner ring, respectively there are the outer raceway of one section circular arc, the symmetrical and curvature R of two outer raceways in the semi outer rings both sides
eIdentical; Respectively there is raceway in one section circular arc half inner ring both sides, the two interior symmetrical and curvature R of raceway
iIdentical, the complete inside and outside raceway of a steel ball is to be made of jointly raceways in adjacent two and two adjacent outer raceways, and steel ball and inside and outside raceway are at 4 and contact and wrapping angle is 45 °.
A lasso is to be made of two semi outer rings and two halves inner ring two-part, and inside and outside raceway all is to be formed jointly by two sections identical circular arcs of curvature, but owing to be that two-part are formed, two sections circular arcs are discontinuous.So steel ball is 4 points with contacting of inside and outside track, and wrapping angle is 45 °.So just guaranteed that this bearing can bear axially and composite force radially.
The utlity model has following advantage: 1, can bear axially and composite force radially; 2, strong shock resistance, long service life and reliability height; 3, can be the supporting use of the helicoid hydraulic motor that digs a directional well.

Fig. 2 is an X enlarged view of the present utility model.
Fig. 3 is a semi outer rings sectional view of the present utility model.
Fig. 4 is half an inner ring sectional view of the present utility model.
(1) semi outer rings; (2) steel ball; (3) half inner rings; (4) outer raceway; (5) interior raceway.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the outer ring is to be made of the identical semi outer rings of several structures (1) assembling, and semi outer rings (1) is arranged with the outer raceway (4) of two sections circular arcs, the curvature R of these two sections outer raceways
eBe identical.Inner ring also is to be made of identical half inner ring (3) assembling of several structures, and respectively there is raceway (5) in one section circular arc half inner ring (3) both sides, and the curvature of two interior raceways (5) is identical and symmetrical.The concrete quantity of semi outer rings (1), half inner ring (3) is decided on the size of load and the model of helicoid hydraulic motor.The inside and outside raceway that steel ball (2) is complete is to be formed jointly by adjacent two interior raceways (5) and adjacent two outside tracks (4) four parts.R
e, R
iAll greater than R ball (R ball one steel ball radius), R
eWith R
iSize also variant.Raceway in two sections (5) curvature is identical but discontinuous, and two sections outer raceways (4) also are like this.Steel ball (2) is 4 points with contacting of inside and outside raceway (5), (4), and wrapping angle is 45 °.
Owing to the contacted inside and outside raceway of steel ball (2) (5), (4), be the discontinuous arc raceways of two-part, thereby make steel ball (2) be at 4 to contact with inside and outside raceway (5), (4).Overcome that raceway is one section complete circular arc in the prior art, steel ball is at 2 with raceway and contacts the shortcoming of being brought.
Claims (1)
1, a kind of four point contact thrust ball bearings, it comprises outer ring, inner ring and steel ball, it is characterized in that outer ring and inner ring all are to be made of identical semi outer rings of structure (1) and half inner ring (3) assembling, respectively there is the outer raceway (4) of one section circular arc semi outer rings (1) both sides, and two outer raceways (4) are symmetrical and curvature Re is identical; Respectively there is raceway (5) in one section circular arc half inner ring (3) both sides, two interior raceways (5) are symmetrical and curvature Ri is identical, the complete inside and outside raceway of steel ball (2) is by raceways (5) in adjacent two and adjacent two outer raceways (4) formation jointly, and steel ball (2) and inside and outside raceway (5), (4) are at 4 and contact and wrapping angle is 45 °.
