Description
Technical field
The utility model relates to technical field of bearings, is specifically related to a kind of full steel ball bearing.
Background technique
In the occasion of some low-speed heave-loads, usually can use full dress ball bearing to improve bearing capacity, but lasso trap becomes again a problem.As shown in Figures 1 to 4, the existing method completely filling ball bearing trap opens an arc notch tilted to extend to end face at the raceway groove place of lasso, when installing last steel ball, alignd by two curve baths of outer ring and inner ring, the installing space increasing rolling element realizes filling out ball.But this notched lasso processing trouble and responsive to axial force.
Summary of the invention
For the deficiency that prior art exists, what the purpose of this utility model was to provide a kind of bearing outer ring crackle formula fills out spherical structure design, fills out spherical structure reasonable in design, fills out ball convenient, and easy to process, the high and full steel ball bearing of service-strong band crackle formula of yield rate.
For achieving the above object, the utility model provides following technological scheme: the full steel ball bearing of a kind of band crackle formula, include bearing inner race, bearing outer ring, and completely fill the roller be arranged between bearing outer ring and bearing inner race, it is characterized in that: described bearing outer ring offers can elasticity open/close up fill out ball crack, fill out ball crack to extend vertically, fill out ball crack vertically and the wall of radial all through-shaft bearing outer-rings, described ball crack of filling out is formed by radially cutting seam along the molybdenum filament connect and extrude breaking joint successively, molybdenum filament cutting seam is positioned at radial outside, extruding breaking joint is positioned at radially inner side.
The full steel ball bearing of the utility model band crackle formula adds man-hour, first on bearing outer ring, cut out molybdenum filament cutting seam with molybdenum filament, molybdenum filament cutting seam guides for following process forms extruding breaking joint, bearing outer ring does not cut off completely, facilitate and follow-up the fine finishing such as grinding are carried out to bearing outer ring, when bearing assemble, press machine is utilized to apply power to bearing outer ring, it is made to split along molybdenum filament cutting seam stress raiser, form extruding breaking joint, thus formed axially and radial all through-shaft bearing outer-rings fill out ball crack, said structure formed to fill out ball crack smooth, joint close is good, easy processing, not easily form chipping, yield rate is high, first insert a part of roller during trap, when filling last roller, with instrument, the ball crack place of filling out of bearing outer ring being strutted certain distance, roller is loaded between bearing inner race and bearing outer ring smoothly, after roller completes assembling, bearing outer ring, in its own resilient effect, restores to the original state, fills out ball crack joint close, fill out ball fracture design, not only processing is simple, and because bearing inner race and bearing outer ring are axially without filling slot, therefore improves axial carrying capacity.
The utility model is set to further: described in fill out ball crack and arrange along the radius of bearing outer ring.Under adopting this further structural design, make to fill out ball crack further and be processed to form conveniently and reliably, fill out ball convenient simultaneously.
The utility model is set to further: the described degree of depth of molybdenum filament cutting seam and the ratio of bearing outer ring minimum wall thickness (MINI W.) are about 0.6 ~ 0.75.This depth of cut scope can ensure outer ring mill add man-hour can not braking effect outer ring machining accuracy also can ensure fine finishing below after break smoothly.
Below in conjunction with accompanying drawing, the utility model is further described.

Embodiment
See accompanying drawing 5 and accompanying drawing 6, the full steel ball bearing of the disclosed a kind of band crackle formula of the utility model, includes bearing inner race 1, bearing outer ring 2, and completely fills the roller 3 be arranged between bearing outer ring 1 and bearing inner race 2.Described bearing outer ring 1 offers can elasticity open/close up fill out ball crack 11, fill out ball crack 11 to extend vertically, fill out ball crack 11 vertically and the wall of radial all through-shaft bearing outer-rings 1, described ball crack 11 of filling out is formed by radially cutting seam 111 along the molybdenum filament connect and extrude breaking joint 112 successively, molybdenum filament cutting seam 111 is positioned at radial outside, and extruding breaking joint 112 is positioned at radially inner side.Wherein, fill out ball crack 11 described in arrange along the radius of bearing outer ring 1.
The full steel ball bearing of the utility model band crackle formula adds man-hour, first on bearing outer ring 1, cut out molybdenum filament cutting seam 111 with molybdenum filament, molybdenum filament cutting seam 111 extrudes breaking joint 112 for following process is formed and guides, and bearing outer ring 1 does not cut off completely, facilitates follow-uply to carry out the fine finishing such as grinding to bearing outer ring 1; When bearing assemble, utilize press machine to apply power to bearing outer ring 1, make it split along molybdenum filament cutting seam 111 stress raiser, form extruding breaking joint 112, thus formed vertically and radial all through-shaft bearing outer-rings fill out ball crack 11; First insert a part of roller during trap, when filling last roller, with instrument, the ball crack place of filling out of bearing outer ring being strutted certain distance, roller is loaded between bearing inner race and bearing outer ring smoothly; After roller completes assembling, bearing outer ring, in its own resilient effect, restores to the original state, fills out ball crack joint close.In this specific embodiment, molybdenum filament the cutting degree of depth h of seam 111 and the ratio of bearing outer ring minimum wall thickness (MINI W.) h1 are about 0.6 ~ 0.75, this depth of cut scope can ensure outer ring grind add man-hour can not braking effect outer ring machining accuracy also can ensure fine finishing below after break smoothly.Fracture design, not only processing is simple, and because bearing inner race and bearing outer ring are axially without filling slot, therefore improves axial carrying capacity; And, said structure formed to fill out ball crack smooth, joint close is good, and easy processing, not easily forms chipping, and yield rate is high.
