Description
Technical field
The utility model belongs to field of mechanical technique, relates to one and removes electrostatic deep groove ball bearing.
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, 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, the phenomenon that can not recline mutually with bearing inner race will soon be there is, thus normally can not play electrostatic efficiency.
