Abstract
The utility model relates to the full steel ball bearing of a kind of outer astragal crackle formula biserial, comprise inner ring and outer ring that axial two ends all have rib, the excircle of described inner ring and the inner circumference of outer ring are equipped with the two row ball race arranged vertically, two row steel balls are filled with between inner ring and outer ring, steel ball is filled in ball race, described outer ring be provided with can elasticity open fill out ball crackle, fill out ball crackle and design vertically, fill out ball crackle axially and radial direction all through.Spherical structure of filling out of the present utility model relates to rationally, and what both facilitated the full steel ball bearing of biserial fills out ball, reliable and stable when ensureing that bearing uses again.
Description
Technical field
The utility model relates to technical field of bearings, is specifically related to the full steel ball bearing of a kind of biserial.
Background technique
The design of two-row ball bearing routine fills out ball angle to be less than 186 °; When the radial bearing capacity that ask for something is large, 186 ° fill out the increase that ball angle limits steel ball number, the filling namely for full dress steel ball bearing cannot realize.In order to realize maximum load rating, need the bearing that full steel ball assembles.
The full steel ball bearing of existing biserial, what it adopted fills out spherical structure for filling out segment mouth.Utilize and fill out the steel ball that breach realizes the full steel ball bearing of biserial and load, but it exists bearing in running, steel ball from the hidden danger of filling out segment mouth and jumping out, and makes bearing failure, there is the unserviceable problem of bearing.
Summary of the invention
For the deficiency that prior art exists, what the purpose of this utility model was to provide a kind of outer ring crackle formula fills out spherical structure design, fills out spherical structure reasonable in design, fills out ball convenient, and the full steel ball bearing of the outer astragal crackle formula biserial of service-strong.
For achieving the above object, the utility model provides following technological scheme: the full steel ball bearing of a kind of outer astragal crackle formula biserial, comprise inner ring and outer ring that axial two ends all have rib, the excircle of described inner ring and the inner circumference of outer ring are equipped with the two row ball race arranged vertically, two row steel balls are filled with between inner ring and outer ring, steel ball is filled in ball race, it is characterized in that: described outer ring be provided with can elasticity open fill out ball crackle, fill out ball crackle to design vertically, fill out ball crackle axially and radial direction all through.
By adopting technique scheme, utilizing device for spreading to strut outer ring being filled out ball crackle, allowing and filling out ball crackle and become the enterable fracture of steel ball, meet the filling of steel ball, after piling steel ball, cancel device for spreading, recover outer ring original state, make full use of the elasticity of outer ring, when steel ball is loaded, fill out ball crackle to strut formation and fill out ball mouth, in use, outer ring restores to the original state, formed and close, solve tradition to offer and fill out segment mouth and cause, the potential safety hazard that steel ball jumps out, improve the operational safety of the full steel ball bearing of biserial.
The utility model is set to further: described outer ring axial end offers the guiding breach being convenient to fill out the formation of ball crackle, guides breach to be positioned at and fills out the axial one end of ball crackle, guides breach to be wedge angle with filling out ball crackle joint.
By adopting technique scheme, start to guide breach at outer ring axial end portion, by instrument to the impact of guiding indentation, there, because the sharp corner stress of breach is concentrated, during impact, at vee place, outer ring Nature creating one Crack, namely fill out ball crackle, the formation of filling out ball crackle reliably facilitates.
The utility model is set to further: described guiding breach is positioned at axial end and rib jointing place inside bearing outer ring.
By adopting technique scheme, being convenient to be processed to form and filling out ball crackle, and after ensureing bearing assemble, outer peripheral surface is smooth, assembling is reliable.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the full steel ball bearing structural representation of the outer astragal crackle formula biserial of the utility model specific embodiment;
Fig. 2 is the utility model specific embodiment outer ring structure schematic diagram;
Fig. 3 is the utility model specific embodiment inner ring structure schematic diagram.
Embodiment
See accompanying drawing 1-3, the full steel ball bearing of the disclosed a kind of outer astragal crackle formula biserial of the utility model, comprise inner ring 1 and outer ring 2, the axial two ends of inner ring 1 have rib 12, axial two ends, outer ring 2 have rib 22, the excircle of described inner ring 1 are equipped with the two row ball race 11 arranged vertically, and the inner circumference of outer ring 2 is provided with the two row ball race 21 arranged vertically, be filled with two row steel balls 3 between inner ring 1 and outer ring 2, steel ball 3 is filled in ball race 11,21.Described outer ring 2 be provided with can elasticity open fill out ball crackle 4, fill out ball crackle 4 and design vertically, fill out ball crackle 4 axially and radial direction all through.
And on the axial end of described outer ring 2, offer the guiding breach 5 being convenient to fill out ball crackle 4 formation, guiding breach 5 to be positioned at and fills out the axial one end of ball crackle 4, guiding breach 5 to be wedge angle with filling out ball crackle 4 joint.In this specific embodiment, for guiding breach 5 to be triangle, the wedge angle that leg-of-mutton drift angle is namely described.
Wherein, described guiding breach 5 be positioned at bearing outer ring 2 inside axial end and rib 22 jointing place.Like this, be convenient to be processed to form and fill out ball crackle, and after ensureing bearing assemble, outer peripheral surface is smooth, assembling is reliable.
Fill out the processing of ball crackle: process guiding breach at outer ring axial end and rib jointing place, by instrument to the impact of guiding indentation, there, because the sharp corner stress of breach is concentrated, during impact, at the crackle that Nature creating outer ring in vee place, outer ring disconnects, namely fill out ball crackle.
Steel ball assembles, in two ball race of the outer ring of bearing and inner ring, all insert half steel ball, and recycling device for spreading struts outer ring being filled out ball crackle, allow and fill out ball crackle and become the enterable fracture of steel ball, steel ball is filled up along fracture, after piling steel ball, cancel device for spreading, recover outer ring original state;
It has, and makes full use of the elasticity of outer ring, when steel ball is loaded, fills out ball crackle and struts formation and fill out ball mouth, meet the filling of steel ball, fill out ball convenient; In use, outer ring restores to the original state, and is formed and closes, and solves tradition and offers and fill out segment mouth and cause, the potential safety hazard that steel ball jumps out, improve the operational safety of the full steel ball bearing of biserial.
