Description
Technical Field
The utility model belongs to the technical field of the bearing, concretely relates to four point contact ball bearing that kinds of riveting are reliable.
Background
The four-point contact ball bearing is kinds of separate type bearings, also can be said set of bearing can bear the angular contact ball bearing of the two-way axial load, its inner, outer lane raceway is peach type cross section, when there is no load or pure radial load acts on, steel ball and ferrule present four-point contact, four-point contact bearing uses on the metallurgical rolling mill extensively, mainly used as the locating bearing, bear the axial force, the outer lane of the bearing is the separable structure composed of two half outer races, steel ball and inner ring combine into body through the cage when the bearing is assembled, it is inseparable structure, every inner wall of pocket used for mounting the steel ball on the cage has rivet point used for preventing the steel ball from disengaging the cage, in the actual application, because rivet point receives the impact of the steel ball directly, with the time extension, the rivet point is apt to lose efficacy because of the abrasion, cause the steel ball to separate and scatter the housing with cage and inner ring, have greatly reduced the life time of the bearing.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing kinds of reliable four point contact ball bearings of riveting point.
The utility model adopts the following technical scheme for accomplishing the above purpose:
A four-point contact ball bearing with reliable riveting points comprises an outer ring, an inner ring, a retainer and a steel ball, wherein the outer ring is of a two-half structure, the inner ring is located in the outer ring, the retainer is located between the outer ring and the inner ring, the steel ball is mounted on the retainer, the inner wall surface of a pocket for mounting the steel ball is provided with riveting points I for preventing the steel ball from separating from the retainer, the riveting points I are at least two of the inner wall surfaces of the pocket, the riveting points I form a -th limiting structure of the steel ball, the outer wall surface of the retainer, which is close to the outer ring side, is provided with annular bosses which are uniformly distributed along the circumference, the annular bosses are provided with a plurality of through holes which are uniformly distributed along the circumference, the through holes correspond to the pocket on the retainer, the through holes are communicated with the pocket to support and limit the steel ball placed in the retainer, the inner wall surface of the through holes is provided with at least two riveting points II for preventing the steel ball from separating from the retainer, the gap between the riveting points II is larger than the gap between.
The riveting points II are uniformly distributed along the circumference of the through hole.
The utility model provides a four point contact ball bearing that kinds of riveting points are reliable adopts above-mentioned technical scheme, designs along the annular boss of circumference equipartition on side outer wall that the retainer is close to the outer lane to design riveting point II on annular boss, riveting point II and the clearance between the steel ball be greater than the clearance between riveting point I and the steel ball, in the use of bearing, when riveting point I is because when wearing and tearing became invalid, carry on spacingly by riveting point II to the bearing, prevent to take place owing to the condition of separating and the cover that looses between steel ball and retainer and the inner circle, advance step improvement bearing's life.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the steel ball riveting device comprises an outer ring, 2, an inner ring, 3, a retainer, 4, a steel ball, 5, riveting points I and 6, riveting points II and 7 and an annular boss.
Detailed Description
The invention is described in connection with the accompanying drawings and the embodiments:
as shown in figure 1, four-point contact ball bearings with reliable riveting points are provided, each four-point contact ball bearing comprises an outer ring 1 with a two-half structure, an inner ring 2 positioned in the outer ring, a retainer 3 positioned between the outer ring and the inner ring, and a steel ball 4 mounted on the retainer, wherein riveting points I5 for preventing the steel ball from separating from the retainer are arranged on the inner wall surface of a pocket for mounting the steel ball on the retainer 3, at least two riveting points I5 are positioned on the inner wall surface of the pocket, a plurality of riveting points I5 form a -th limiting structure of the steel ball, annular bosses 7 uniformly distributed along the circumference are arranged on the outer wall surface of the retainer 3 close to the outer ring 1 side, a plurality of through holes uniformly distributed along the circumference are arranged on the annular bosses 7, the through holes correspond to the pocket on the retainer 3, the through holes are communicated with the pocket to support and limit the steel ball placed in the pocket, the riveting degree of the pocket and the through holes is increased by the riveting degree of , the steel ball supporting the steel ball is limited by the steel ball entering , at least two spacing points I for preventing the inner wall of the retainer from separating from the second spacing point II, and the spacing 6 of the second spacing point II between the steel ball is larger than the spacing point 6 of the spacing.
The riveting points II 6 are uniformly distributed along the circumference of the through hole.
When the bearing is assembled, the steel ball and the inner ring are combined into bodies through the retainer, the bearing is of an inseparable structure, the steel ball is limited by the riveting points I5 on the inner wall surface of each pocket of the retainer, the steel ball and the riveting points I5 on the retainer continuously impact along with the use of the bearing, the riveting points I5 are gradually abraded, the steel ball is limited by steps at the level of as the size of a steel ball mounting hole formed by the through hole and the pocket on the retainer is increased, the play in the steel ball mounting hole formed by the pocket of the steel ball and the through hole is increased due to the abrasion of the riveting points I5, and the steel ball is limited by the riveting points II 6 on the through hole along with the use of the bearing.
Claims (2)
- The four-point contact ball bearing with reliable riveting points is characterized in that the outer wall surface of the retainer close to the outer ring side is provided with annular bosses uniformly distributed along the circumference, the annular bosses are provided with a plurality of through holes uniformly distributed along the circumference and correspond to the pockets on the retainer, the through holes are communicated with the pockets to jointly support and limit the steel balls placed in the through holes, the inner wall surfaces of the through holes are provided with at least two riveting points II for preventing the steel balls from being separated from the retainer, the clearance between the riveting points II and the steel balls is larger than the clearance between the riveting points I and the steel balls, and the riveting points II form a second channel limiting structure of the steel balls.
- 2. The kinds of reliable riveted point four-point contact ball bearing as claimed in claim 1, wherein the riveting points II are uniformly distributed along the circumference of the through hole.
