Abstract

The utility model relates to a deep groove ball bearing with an inclined filling ball gap, which belongs to the technical field of rolling bearings. The utility model is characterized in that a sleeve ring gap of the heavy load deep groove ball bearing is commonly straight, and the central line of the gap is vertical to the central radial plane surface of a rolling channel; the straight gap cut the rolling channel of the bearing. When the utility model is at work, a steel ball and the intersecting line of the gap and the bearing rolling channel have obvious head-on impact effect, the running noise of the bearing is raised and the service life of the bearing is short. The straight gap is changed into an inclined gap, the cut for the bearing rolling channel is obviously reduced in the same locking amount, the head-on impact effect of the steel ball and the intersecting line of the gap and the bearing rolling channel is reduced when the utility model is at work, thereby, the running noise of the bearing is reduced. The service life of the bearing is extended, and the utility model is practical design.

Description

A kind of with the deep groove ball bearing of tiltedly filling out the segment mouth

Technical field: belong to technical field of rolling bearings

Background technique: in the rolling bearing, deep groove ball bearing is mainly used to bear radial load.In order to improve bearing capacity, the segment mouth is filled out in processing on the lasso of being everlasting, and inserts than the more ball of standard rolling bearing in bearing.The existing segment mouth of filling out all is straight breach, be that breach center line and radial plane, bearing race center are perpendicular, cause bearing race is eliminated area and volume is bigger, the intersection angle of steel ball revolution direction and breach and raceway is an acute angle, the shock effect that " heads on " is obvious, damage near deficiencies such as the raceway of steel ball and breach easily, these deficiencies directly cause noise increase in the straight breach bearing operation process, have a strong impact on the contact fatigue life of bearing.

Summary of the invention:

The utility model is will provide to fill out the bearing capacity that ball increases bearing more, can reduce straight breach again to greatest extent bearing operation noise and life-span etc. are brought a kind of with the deep groove ball bearing of tiltedly filling out the segment mouth of adverse effect.

Technical solution adopted in the utility model:

Fill out the segment mouth what load radial plane, the center inclination that has its center line and lasso raceway on the inside and outside circle of rolling element.This inclination breach is to fill out segment mouth center line and radial plane, lasso center angle one side is the obtuse angle, and a side is an acute angle, and acute angle and obtuse angle be the supplementary angle each other, and wherein the acute angle scope is 1～89 degree.

Filling out the segment mouth can only be laid on the bearing outer ring, or only is laid on the bearing inner race, also can be laid in simultaneously on bearing outer ring and the inner ring.The breach center line can the outside and inboard contour, also can be inboard a little more than the outside.Filling out its gap width scope of segment mouth is 1～D _bMillimeter, wherein, D _bBy in the bearing the diameter of dress ball.

After implementing the utility model, because bearing is filled out the segment mouth along oblique laying, under the same hold depth, excision to the lasso raceway obviously reduces than existing straight breach, steel ball revolution direction and the oblique wherein side of breach and the raceway intersection shock effect that " heads on " obviously weakens even eliminates, thereby greatly reduced all negative effects that bring to bearing because of breach, running noise that reduces bearing and the life-span of improving bearing have been had positive effect.

A-A schematic representation during analyse and observe the outer ring that Fig. 3 tiltedly fills out the segment mouth for band.

The inner ring cross-sectional view that Fig. 4 tiltedly fills out the segment mouth for band.

Fig. 5 is that A among Fig. 4 is to view.

Embodiment:

Now the utility model is described in further detail in conjunction with the accompanying drawings:

Fill out segment mouth 5,6 what load radial plane, the center inclination that has its center line and lasso raceway on the inside and outside circle of rolling element 3, this inclination breach is to fill out segment mouth center line and radial plane, lasso center angle is α, one side is the obtuse angle, one side is an acute angle, acute angle and obtuse angle are the supplementary angle, wherein the desirable 1-89 degree of acute angle scope.Filling out the segment mouth can only be laid on the bearing outer ring 6, or only is laid on the bearing inner race 5, also can be laid in simultaneously on bearing outer ring 6 and the inner ring 5; The breach center line can the outside and inboard contour, also can be inboard a little more than the outside.Fill out its gap width scope of segment mouth for being 1～D _bMillimeter, wherein, D _bBy in the bearing the diameter of dress ball.

Below, be with simultaneously with bearing inner race and outer ring that tiltedly to fill out the segment mouth be example, illustrate that band tiltedly fills out the process for making of the deep groove ball bearing of segment mouth:

1, by normally bearing inner race 2 and 1 each surface, outer ring not being carried out grinding with the bearing ring processing technology of filling out the segment mouth;

2, use general universal grinder or special purpose grinder, grinding goes out tiltedly to fill out segment mouth 6 on bearing outer ring, and grinding goes out tiltedly to fill out segment mouth 5 on bearing inner race;

3, an end of inner ring and outer astragal tiltedly being filled out the segment mouth places the same side to fill out ball 3, and several the balls of Duoing than normal bearing are inserted from indentation, there after inner ring breach and outer ring breach are aligned.When hold depth was big, last several balls were inserted from indentation, there after can adopting lever reinforcing or mode of heating to make race deformation and expansion again;

4, with ball five equilibrium along the circumferential direction, place retainer 4, punch riveting is promptly made the utility model that band is tiltedly filled out the deep groove ball bearing of segment mouth.

When 5, installing and using band and tiltedly fill out the deep groove ball bearing of segment mouth, the revolution direction that as far as possible makes ball is oblique identical with breach, bearing is packed into use in the main frame.
