Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The scope of protection of the invention.
- Fig. 3 is please referred to Fig.1, Fig. 1 is the structural schematic diagram for the bearing assembly part that the embodiment of the present invention is provided；Fig. 2 is
The partial enlarged view for the bearing assembly a-quadrant that Fig. 1 is provided；Fig. 3 is the bearing heat conduction for the bearing that the embodiment of the present invention is provided
The structural schematic diagram of device.
The bearing that the embodiment of the present invention is provided, including bearing outer ring 40 and bearing heat-transfer device 411, bearing outer ring 40 are opened
Equipped with thermal hole 42, thermal hole 42 extends along 40 radial direction of bearing outer ring；Bearing heat-transfer device 411 is fixed on thermal hole 42
In, the height of bearing heat-transfer device 411 is less than or equal to the height of thermal hole 42.
As it can be seen that bearing outer ring 40 offers thermal hole 42, for placing bearing heat-transfer device 411.Thermal hole 42 can be opened
It is located at the rib of bearing outer ring 40, can also be opened at the non-rib of bearing outer ring.Bearing can be biserial or multiple row rolling
Dynamic bearing can also be single-row rolling bearing.
It should be noted that rib of the present invention refers to close to the bearing outer ring region at roller both ends, for biserial
Or for multiple row roller bearing, the rib between adjacent rollers includes the rolling between adjacent roller and close to roller end
Intermediate rib of sub- terminal block while with connection roller terminal block.
The bearing that an embodiment of the present invention is provided is the rib that thermal hole 42 can be opened in bearing outer ring 40
Place, this is because in bearing operational process, rib can bear the axial force of roller 10, if rib is very big by axial force, rib
Sliding friction can occur with 10 end of roller, temperature increases.Once the temperature of rib is excessively high, the viscosity of lubricant will reduce,
Lubricating status becomes mixed lubrication even boundary lubrication by elastohydrodynamic lubrication (i.e. elastohydrodynamic lubrication), and then leads to roller 10
End and rib contact site insufficient lubrication, frictional force increased dramatically, and local temperature further increases, and aggravate lubricant aging,
And bearing lubrication state is influenced, aggravate 10 end of roller and rib abrasion, to influence bearing life.Due to bearing outer ring 40
Thermal hole 42 is offered at rib, the bearing heat-transfer device 411 being fixed in thermal hole 42 is contacted with rib, by heat transfer,
Heat transfer at rib is to bearing heat-transfer device 411, and bearing heat-transfer device 411 is by the heat of Bearing inner along bearing outer ring
40 radial directions pass so that rib temperature reduces.Since rib is closer apart from raceway, rib temperature change is also between meeting
Connecing influences the temperature change of raceway, therefore rib temperature reduces so that the reduction of Bearing inner temperature, delays lubricant aging fast
Degree reduces frictional force, 10 end of roller and rib abrasion is reduced, to extend bearing life.
When bearing is biserial or multiple row roller bearing, thermal hole 42 can also be opened in the rib between adjacent rollers
On.On the one hand, the rib area between adjacent rollers is larger, opens up thermal hole 42 and is comparatively easier；On the other hand, when leading
When hot hole 42 is opened at the rib between adjacent rollers, bearing heat-transfer device 411 can connect with two roller terminal block sides simultaneously
It touches, while the heat at two roller terminal block sides being conducted, to reduce Bearing inner temperature.
The shape of 42 cross section of thermal hole can be circle, in other embodiments, the shape of 42 cross section of thermal hole
