Fig. 3 is the B place enlarged view of Fig. 1.
In figure: inner ring body 10, axis hole 11, junction surface 12, baffle ring 30, second baffle ring inclined-plane 31, chamfer surface 13, first baffle ring 20, first baffle ring inclined-plane 21, second, outer inclined-plane 40, ball grooves 50, first groove 51, second groove 52.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the narrow inner ring of a kind of automobile-used special-shape bearing, comprise inner ring body 10, there is in inner ring body 10 axis hole 11, described inner ring body 10 one end extends to form the first annular baffle ring 20 to the radial direction of outer inner ring body 10, the other end extends to form the second annular baffle ring 30 to the radial direction of outer inner ring body 10, the external diameter of the first baffle ring 20 is greater than the second baffle ring 30 external diameter, inner ring body 10 outer wall between first baffle ring 20 and the second baffle ring 30 forms the outer inclined-plane 40 of taper, outer inclined-plane 40, first baffle ring 20 and the second baffle ring 30 surround the ball grooves 50 formed for accommodating ball, the surface that first baffle ring 20 is positioned at ball grooves 50 has the first baffle ring inclined-plane 21 of taper, the surface that second baffle ring 30 is positioned at ball grooves 50 has the second baffle ring inclined-plane 31 of taper, the width on the first baffle ring inclined-plane 21 is greater than the width on the second baffle ring inclined-plane 31.
Again shown in composition graphs 2 and Fig. 3, angle α between first baffle ring inclined-plane 21 and outer inclined-plane 40 is greater than 89 ° and is less than 90 °, angle β between the second described baffle ring inclined-plane 31 and outer inclined-plane 40 is greater than 90 ° and is less than 91 °, this design, the bottom of ball grooves 50 and the first baffle ring inclined-plane 21 and the second baffle ring inclined-plane 31 is made to be in non-perpendicular state, suppression is played to ball, prevent ball from departing from ball grooves 50, on the other hand, because the angle tilted is less, ball easily snaps onto in ball grooves 50, is convenient to the installation of bearing.Wherein, the first baffle ring inclined-plane 21 and the second baffle ring inclined-plane 31 can be parallel to each other, also can be not parallel, but are preferably parallel to each other.
Specifically, the bottom land both sides of ball grooves 50 have the first groove 51 extended in the first baffle ring 20 and the second groove 52 extended in the second baffle ring 30, lubricant grease (as butter or butter) can be placed in the first groove 51, for lubricating the ball in ball grooves 50, play the effect of selflubricating, thus it is more flexible that ball is rotated.The degree of depth of the first groove 51 is greater than the degree of depth of the second groove 52.First groove 51 and the second groove 52 all have semicircular bottom, and this design is mainly considered and can also be placed seal ring in the first groove 51 and the second groove 52, thus play and position effect to the ball in ball grooves 50.
The two ends of axis hole 11 outwards expand and form uncovered shape, are convenient to be connected with inner ring body 10 after rotating shaft is inserted.Preferably, one end that axis hole 11 is positioned at the first baffle ring 20 inwall has the junction surface 12 of arc, and the other end being positioned at the second baffle ring 30 inwall has chamfer surface 13.
The utility model is reasonable in design, and structure is ingenious, both ball can easily be put in ball grooves 50, effectively can prevent again ball from rotation process, departing from ball grooves 50, thus improve antiwhip; In addition, the design of the first groove 51 and the second groove 52, makes, when this inner ring is for bearing, to play self-lubricating function to bearing, can position again, further increase the stability of bearing working to the positioning of ball.
