Description
Technical field
The utility model belongs to field of mechanical technique, relates to the deep groove ball bearing that a kind of outer ring is anti-skidding.
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 when being installed on the positions such as main frame when bearing, bearing rotary produce heat and bearing support in heat the bearing outer ring in bearing and bearing support itself can be caused radially to expand, due to the reason that material is different, the size that bearing support radially expands is greater than the size that bearing outer ring expands usually, so just cause, between bearing support and bearing outer ring, there is larger gap, thus bearing is easily wriggled in the running, and then affect the stability of bearing operation.
China patent CN 203412951U discloses the anti-skid structure in a kind of bearing, this bearing comprises bearing inner race and the bearing outer ring of coaxial setting, several balls are provided with between bearing inner race and bearing outer ring, anti-skid structure comprises two locking grooves be opened on bearing outer ring outer side wall, locking groove ringwise and coaxially arrange with bearing outer ring, locking groove is embedded is connected to an O type circle, the inner side surface of O type circle has several hemisphere floating-points, the bottom land of locking groove offers several hemisphere shrinkage pools.This bearing can increase the frictional force between O type circle and locking groove, avoids O type circle to slide in locking groove, improves the anticreep function of bearing.
But, when there is gap between bearing outer ring and bearing support, now O type circle is subject to larger external force, and the hemisphere floating-point on O type circle also can be subject to larger shearing force, the joint of hemisphere floating-point and O type circle inner headed face is easy to occur tearing because of stressed, and then reduces the anticreep performance of this bearing.
Summary of the invention
The utility model is the problems referred to above existed for existing technology, and provide the deep groove ball bearing that a kind of outer ring is anti-skidding, technical problem to be solved in the utility model is: the anticreep performance how improving this deep groove ball bearing.

The deep groove ball bearing that a kind of outer ring is anti-skidding, described deep groove ball bearing comprises bearing inner race and the bearing outer ring of coaxial setting, several balls are provided with between described bearing inner race and bearing outer ring, it is characterized in that, the periphery of described bearing outer ring offers a locking groove, described locking groove and this bearing outer ring are coaxially arranged, the bottom land of described locking groove offers several grooves, described deep groove ball bearing also comprises two hemizonids adopting iron plate to make, the thickness of described hemizonid is less than the degree of depth of described locking groove, the two ends of one of them hemizonid removably connect with the two ends of another hemizonid respectively, the internal surface of described hemizonid has the projection that can be plugged in described groove, the outer surface of described hemizonid has a rubber pad, thickness and the degree of depth being greater than described locking groove of described hemizonid and rubber pad.
Its working principle is as follows: this deep groove ball bearing when mounted, can two hemizonids be installed in locking groove by projection, and the two ends of two hemizonids are connected, again whole bearing is installed in bearing support, when there is gap between the two because of expanded by heating in bearing outer ring and bearing support, rubber pad on hemizonid still can play good compensating action, avoids bearing to occur wriggling.And be arranged on hemizonid due to rubber pad in the application, and hemizonid is that employing is metal, and be plugged in groove by the projection on hemizonid, metal projection and hemizonid joint are not easily torn because of stressed, effectively improve its working life, and then the anticreep performance of bearing integral can be improved.The iron plate that hemizonid in the application is selected is good with thin iron plate, makes it that certain bending deflection can occur, with convenient for assembly.
At the deep groove ball bearing that above-mentioned a kind of outer ring is anti-skidding, as a kind of scheme, one end of described hemizonid offers a draw-in groove, and the other end of described hemizonid has a boss, and the boss on one of them hemizonid can be plugged in the draw-in groove on another hemizonid.
At the deep groove ball bearing that above-mentioned a kind of outer ring is anti-skidding, alternatively, one end of described hemizonid has a buckle, and the other end of described hemizonid has grab, and the grab on one of them hemizonid can with the buckle phase clamping on another hemizonid.
At the deep groove ball bearing that above-mentioned a kind of outer ring is anti-skidding, as the third scheme, one end of described hemizonid offers a through hole, the other end of described hemizonid has cylindrical projection, projection on one of them hemizonid can be plugged in the through hole on another hemizonid, and described projection and through hole are all arranged along the radial direction of described bearing outer ring.Projection and through hole are all arranged along the radial direction of bearing outer ring, then effectively can ensure the connective stability between two hemizonids, hemizonid is not easily skidded off in locking groove, and then improve the anticreep performance of this bearing.
At the deep groove ball bearing that above-mentioned a kind of outer ring is anti-skidding, the internal surface of described rubber pad offers a mounting groove, and described hemizonid is embedded in described mounting groove.
At the deep groove ball bearing that above-mentioned a kind of outer ring is anti-skidding, described ball is hollow spheroid.
Compared with prior art, the utility model has the following advantages:
1, because rubber pad in the application is arranged on hemizonid, and hemizonid is that employing is metal, and be plugged in groove by the projection on hemizonid, metal projection and hemizonid joint are not easily torn because of stressed, effectively improve its working life, and then the anticreep performance of bearing integral can be improved.
