Description
Technical field
A kind of rotatable support is the utility model is related to, more particularly to a kind of high leakproofness deep groove ball bearing.
Background technology
Deep groove ball bearing is most representational rolling bearing, and such bearing friction coefficient is small, and limit speed is high, structure letter
Single, manufacturing cost is low, easily reaches the higher accuracy of manufacture, size range and form change are various, extensive as gearbox bearing
Use.
Deep groove ball bearing is made up of outer ring, inner ring, steel ball, steel retainer and closure mostly, is found under study for action, although
We by this class bearing rolling bearing, actually due to bearing working face in the rolling bearing course of work（That is steel ball and raceway groove
Contact surface size）Geometry and crudy difference, steel ball be not PURE ROLLING in channels, moment can produce
Relative to slide, this slides both easy frictional heats relatively, also increases turning moment and increase power consumption.
When bearing is applied to the occasion of high-speed rotation, substantial amounts of frictional heat can be produced between bearing, it is big producing
While measuring frictional heat, lubricating grease can accelerate to volatilize in bearing；When lubricating grease deficiency, bearing can aggravate to be lost；And conventional
Closure dense block lipid can on can be insufficient so that bearing tear open lid fill out fat cycle it is shorter, while fat is filled out,
The sealing property of closure can further decline again.
Utility model content
The purpose of this utility model is to provide a kind of high leakproofness deep groove ball bearing, which solves existing deep groove ball bearing
Sealing cover lock lipid can it is insufficient the problem of.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of high leakproofness deep groove ball bearing, including the outer ring of bearing, inner ring, set ball between outer ring and inner ring and
The retainer that ball is along the circumferential direction separated, the first seal groove is circumferentially provided with the inwall of the outer ring, described first is close
Sealing groove includes the bent sealing groove that sunken inside is formed vertically, and closure is embedded between the inner ring and outer ring, the closure
Abutted simultaneously with the first seal groove and bent sealing groove；The outer ring is set on the inwall between the first seal groove and axial end
There is screw thread, the endoporus internal thread of the outer ring, which is connected with, to abut to the retaining ring of closure end face；Set on the outer wall of the inner ring
The second seal groove is equipped with, the inner circle gap of the closure is connected in the second seal groove.
Using such scheme, after in ball and inner ring and outer ring, friction generates heat, the lubricating grease on contact surface can add
Speed liquefaction or volatilization；And volatilize or liquefy it is excessive can only be from the gap between the gap or inner ring and closure of outer ring and closure
Overflow；And needed between outer ring and closure by between closure and axial, the bent sealing groove and the first seal groove of outer ring
Gap is abutted, the structure of circuitous reflux can be formed between these gaps；And after the compression for passing through retaining ring, these gaps will
Become minimum, and volatilize and can float, liquefaction can sink to bottom, and the lubricating grease largely to volatilize can form stop between outer ring；
And sealing is also strengthened by the roundabout stop of the second seal groove between inner ring and closure, both combine to form fabulous lock
Fat effect, so as to which effectively the cycle of fat maintenance is filled out in the service life of extension bearing and extension.
More preferably：The inwall of the closure is recessed compensating tank, is provided with second seal groove outer
The resistance envelope portion convexed into, the resistance envelope portion coordinate with compensating tank gap.
Using such scheme, the combination of group sealing and the second seal groove strengthens, the roundabout stop of the second seal groove, so as to
Add sealing.
More preferably：The closure includes heat conduction frame and rubber standoff, and the heat conduction frame includes being embedded in rubber
Support towards the side of ball heat-conducting plate and it is multiple through rubber standoff and another axial end of rubber standoff expose dissipate
Hot head；Inwall of the heat-conducting plate with the first seal groove vertically abuts.
Using such scheme, in bearing installation and when use, outer ring remains stationary as, and inner ring produces relative turn
It is dynamic；Outer ring abuts with ball, and inner ring abuts with ball, and ball contacts with retainer；And three is typically that metal material is led
Hot property is preferable, in addition, heat-conducting plate abuts with outer ring；Pass through heat while frictional heat is produced between ball and inner ring or outer ring
Conduction is to heat-conducting plate, and heat-conducting plate is connected with heat dissipation head, is outwardly radiated finally by heat dissipation head, so as to ensure the same of sealing
When strengthen the heat dispersion of bearing；After radiating, the volatilization of lubricating grease and liquefaction leakage situation can also be alleviated；In addition, heat conduction
Frame can play a part of support to rubber standoff so that rubber standoff still can have good branch after high-temperature heating softens
Support sealing effectiveness.
More preferably：The bottom land of the compensating tank, which is provided with, is communicated to heat-conducting plate and the contact surface of rubber quality inspection
Return fat passage.
Using such scheme, increase return flow line, simultaneously because the gap between heat-conducting plate and rubber standoff is smaller, be not easy
It is in the presence of excessive.
More preferably：The heat dissipation head is T-shaped along the section for crossing heat dissipation head axis, and the axial surface of heat dissipation head with
Rubber standoff abuts.
Using such scheme, increasing heat radiation area, and heat dissipation head is prevented to be separated with rubber standoff.
More preferably：The center of the inner ring is recessed interior raceway groove, and the center of the outer ring is recessed to be formed
Outer raceway groove, both ends of the ball along bearing radial direction are respectively engaged with interior raceway groove and outer raceway groove.
Using such scheme, for placing ball, and certralizing ability is played.
More preferably：The interior raceway groove radius of curvature is 0.529 times of steel ball size, and outer raceway groove radius of curvature is steel
0.521 times of bulb diameter.
Using such scheme, interior raceway groove radius of curvature increases than the interior raceway groove radius of curvature of standard deep groove ball bearing
2.8%, bearing outer raceway groove radius of curvature reduces 0.8% than the outer raceway groove radius of curvature of standard deep groove ball bearing, reduces steel ball
Axial float and sliding friction probability in outer raceway groove, reduce the arc length of interior raceway groove envelope steel ball, improve interior raceway groove with
The radiating condition in steel ball working face, improve the heat dispersion of bearing working face.
More preferably：The both sides of the interior raceway groove and outer raceway groove, which are respectively provided with, deposits fat groove, described to deposit fat groove and interior raceway groove
Or outer raceway groove is connected.
Using such scheme, can prestore partial lubrication fat in interior raceway groove and outer raceway groove, lubricated surface lubricating grease by
Supplement can be instantly obtained after heat loss.
More preferably：The inner surface of described closure is the smooth surface of fine grinding.
Using such scheme, because of the heat of friction generation when can reduce bearing working, temperature rise when bearing runs at high speed is reduced
Value.
In summary, the utility model has the advantages that：
1st, by the heat conduction and heat radiation structure added on closure, the thermal diffusivity of bearing is strengthened while ensureing and sealing
Energy；The structural strength of closure is also provide enhanced simultaneously, is kept from heat and is softened and loosen；
2nd, multiple circuitous channel and return flow line, and locking mechanism, enforced lock fat ability, it is excessive to alleviate lubricating grease volatilization
Situation.
