Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of deep groove ball bearing of long service life.
Background technique
Deep groove ball bearing is a type the most common in rolling bearing, and the deep groove ball bearing of basic model is made up of an outer ring, inner ring, one group of steel ball and one group of retainer.Deep groove ball bearing substantial radial load, also can bear radial load and thrust load simultaneously.When it only bears radial load, wrapping angle is zero.When deep groove ball bearing has larger radial internal clearance, have the performance of angular contact bearing, can bear larger thrust load, the friction factor of deep groove ball bearing is very little, and limit speed is also very high.
And owing to there is radial internal clearance between the bearing inner race in above-mentioned patent and bearing outer ring, when bearing rotary, lubricant oil can form oil film in the inner tracks of bearing, so be insulation between bearing inner race and bearing outer ring.And when bearing inner race rotates along with axle, easily produce electrostatic, owing between bearing inner race and bearing outer ring being insulation, when buildup of static electricity to a certain extent after easily produce spark, thus make equipment there is potential safety hazard.
In order to solve the problem, China patent CN 203412956U discloses a kind of bearing, this bearing comprises bearing inner race and the bearing outer ring of coaxial setting, the axis of bearing inner race and the axis of bearing outer ring are all in the horizontal direction, several balls are provided with between bearing inner race and bearing outer ring, the madial wall of bearing outer ring offers dustproof groove, bearing also comprises dust cover, the outside of dust cover is connected in dustproof groove, the outer side wall direction of the interior side direction bearing inner race of dust cover extends, the inside portion of dust cover is also removably connected with static bruss, static bruss and dust cover is gone all to adopt conductive metal to make, and go the outer end of static bruss and the outer side wall of bearing inner race to lean.Owing to being provided with static bruss inside the dust cover in above-mentioned bearing, due to dust cover and go static bruss all to adopt conductive metal to make, the electrostatic produced when bearing inner race rotates can by going static bruss via bearing outer ring, bearing support and chassics earth, avoid the buildup of static electricity of bearing, reduce the potential safety hazard of equipment.
But, still there are the following problems for above-mentioned bearing: 1, because bearing inner race frequently rotates relative to bearing outer ring, the wire on static bruss is gone to recline mutually with bearing inner race for a long time, will soon wear and tear, after wearing and tearing occur wire, its length reduces, and will soon occur the phenomenon that can not recline mutually with bearing inner race, thus normally can not play electrostatic efficiency, can only bearing be changed, cause the working life of bearing shorter; 2, owing to going the wire on static bruss thinner and frequently stressed, so be easy to occur fractureing, the wire after fractureing easily directly drops on the surface of contact of ball and raceway, is easy to the clamping stagnation causing bearing, also can affects the working life of bearing.
Summary of the invention
The utility model is the problems referred to above existed for existing technology, a kind of deep groove ball bearing of long service life is provided, technical problem to be solved in the utility model is: how improve this deep groove ball bearing remove static performance while, avoid this deep groove ball bearing to occur clamping stagnation, thus improve the working life of this deep groove ball bearing.
The purpose of this utility model realizes by following technical proposal:

Its working principle is as follows: this deep groove ball bearing in use, bearing inner race rotates the electrostatic produced, and be passed on bearing outer ring by wire, conductive pole, wire, bearing outer ring is by bearing support and rack earth, avoid the buildup of static electricity of bearing, reduce the potential safety hazard of equipment.Because the wire in the application is posted by bearing inner race under elastic pressure by spiral rubber pipe, when there are wearing and tearing in wire, wire still can recline mutually with bearing inner race under the elastic force effect of spiral rubber pipe, the electrostatic grounding produced by bearing inner race can be continued, that improves this bearing removes static performance, and can improve the working life of bearing.Meanwhile, as wire ruptures, the adsorbable post-rift wire of magnetic sheet, avoids wire to drop and cause bearing clamping stagnation between ball and raceway, thus improve the working life of this bearing.And the length of wire is the reason of 1.2 times of spiral rubber length of tube, then be when spiral rubber pipe generation beat, can there is synchronous hunting in conductive pole, wire is longer, can avoid self rupturing, and wire can not be long simultaneously, is in order to avoid wire beat is in raceway.
In the deep groove ball bearing of above-mentioned a kind of long service life, the inner headed face of described bearing outer ring is fixed with a column, described column offers the cable-through hole passed for described wire.After being designed with column and cable-through hole, certain position-limiting action can be played to wire, avoid wire long generation beat to affect normal rolling or the fracture of self of ball.
In the deep groove ball bearing of above-mentioned a kind of long service life holds, in described cable-through hole, be plugged with the sleeve pipe that an employing rubber is made.After being designed with sleeve pipe, the wearing and tearing of producing because of mechanical interference when can reduce wire and other component contact.
In the deep groove ball bearing of above-mentioned a kind of long service life, the outer end of described conductive pole is bent to form flange along self radially outward, described flange offers through hole one, and the inner of described wire has the buckle one that can be interlockingly connected with described through hole one.After being designed with buckle one and through hole one, connection and the replacing of wire can be facilitated.
In the deep groove ball bearing of above-mentioned a kind of long service life, the inner headed face of described bearing outer ring has an installation sheet, described installation sheet offers through hole two, the outer end of described wire has the buckle two that can be interlockingly connected with described through hole two.
Compared with prior art, the utility model has the following advantages:
1, the wire in the application is posted by bearing inner race under the elastic pressure by spiral rubber pipe, when there are wearing and tearing in wire, wire still can recline mutually with bearing inner race under the elastic force effect of spiral rubber pipe, can continue the electrostatic grounding produced by bearing inner race, that improves this bearing removes static performance.Meanwhile, as wire ruptures, the adsorbable post-rift wire of magnetic sheet, avoids wire to drop and cause bearing clamping stagnation between ball and raceway.
