In order to solve the problems of the technologies described above, this case is life therefrom.
Summary of the invention
The purpose of this utility model is: provide that a kind of good heat dissipation effect, noise are low, the heat radiating type automobile bearing of long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of heat radiating type automobile bearing, comprise bearing inner ring, outer race and the retainer with rolling element, two ends that bearing inner ring and outer race are formed are respectively arranged with oil sealing, on the inner ring face of described outer race and face, outer ring offers respectively some axially extension and the bar-shaped trough of circumference distribution, bar-shaped trough on outer race inner ring face and the bar-shaped trough one_to_one corresponding on face, outer ring are arranged, thermal conductivity colloidal silica is provided with in each bar-shaped trough, be positioned at corresponding two thermal conductivity colloidal silicas on outer race inner ring face and face, outer ring to be interconnected by some thermal conductors.
Further, outer race inner ring face and face, outer ring are often provided with between corresponding two bar-shaped troughs the receiving hole of some connections two bar-shaped troughs, and thermal conductor is arranged in receiving hole.
Further, the inner ring face of the outer edge surface and outer race that are positioned at the thermal conductivity colloidal silica on outer race inner ring face is complete cambered surface transition structure.
Further, the notch of outer edge surface lower than place bar-shaped trough of the thermal conductivity colloidal silica on face, outer race outer ring is positioned at.
Further, described thermal conductor is made up of thermal conductivity silica gel.
The utility model compared with prior art, have the following advantages: the utility model heat radiating type automobile bearing, the thermal conductivity colloidal silica be positioned on outer race inner ring directly contacts with rolling element, so, outer race and the fricative heat of rolling element can be attached on this thermal conductivity colloidal silica, and be delivered to rapidly on the thermal conductivity colloidal silica that is positioned on outer race outer ring by thermal conductor, rapidly, realize heat to shift from Bearing inner to Bearing outer thoroughly, and dissipate eventually through air, whole bearing good heat dissipation effect, long service life; , directly contacted with rolling element by hot colloidal silica meanwhile, can also effectively reduce the noise produced because of friction.
Accompanying drawing explanation
Fig. 1 is the external structure schematic diagram of the utility model heat radiating type automobile bearing.
In Fig. 2 Fig. 1, A-A is to sectional view.
Shown in figure: 1, bearing inner ring 2, outer race 3, retainer 4, rolling element 5, oil sealing 6, bar-shaped trough 7, thermal conductivity colloidal silica 71, interior thermal conductivity colloidal silica 72, outer thermal conductivity colloidal silica 8, thermal conductor 9, receiving hole.
Embodiment
Below by drawings and Examples, the utility model is further elaborated.
As depicted in figs. 1 and 2: a kind of heat radiating type automobile bearing, bearing inner ring 1, outer race 2 and the retainer 3 with rolling element 4 is comprised.Two ends that bearing inner ring 1 and outer race 2 are formed are respectively arranged with oil sealing 5.On the inner ring face of outer race 2 and face, outer ring offers respectively some axially extension and the bar-shaped trough 6 of circumference distribution.Bar-shaped trough 6 on outer race inner ring face is arranged with bar-shaped trough 6 one_to_one corresponding on face, outer ring.Thermal conductivity colloidal silica 7 is provided with in each bar-shaped trough 6.Be positioned at corresponding two thermal conductivity colloidal silicas 7 on outer race 2 inner ring face and face, outer ring to be interconnected by some thermal conductors 8.Below note is positioned at the thermal conductivity colloidal silica 7 on outer race inner ring face is thermal conductivity colloidal silica 71, and the note thermal conductivity colloidal silica 7 be positioned on face, outer race outer ring is outer thermal conductivity colloidal silica 72.Thermal conductor 8 is actually intermediate carrier, and the heat of interior thermal conductivity colloidal silica 71 is delivered on outer thermal conductivity colloidal silica 72 by thermal conductor 8.
In the present embodiment, outer race 2 inner ring face and face, outer ring are often provided with between corresponding two bar-shaped troughs 6 receiving hole 9 of some connections two bar-shaped troughs 6, thermal conductor 8 is arranged in receiving hole 9, the inner of thermal conductor 8 contacts with interior thermal conductivity colloidal silica 71, and the outer end of thermal conductor 8 contacts with outer thermal conductivity colloidal silica 72.In order to make heat transfer effect better, thermal conductor 8 is also made up of thermal conductivity silica gel.
In the present embodiment, the outer edge surface of outer thermal conductivity colloidal silica 72 and the inner ring face of outer race 2 are complete cambered surface transition structure.So, can guarantee that the inner ring face of outer race 2 is smooth, smooth, thus stability when improving bearing outer ring and rolling element 4 rolling friction.
In the present embodiment, the outer edge surface of outer thermal conductivity colloidal silica 72 is lower than the notch of place bar-shaped trough 6.So, between outer thermal conductivity colloidal silica 72 and the inwall of bearing mounting hole, there is certain interval, be beneficial to heat and be dispersed in air, can further improve the heat dispersion of bearing.
Above-described thermal conductivity silica gel is a kind of existing material, and it is the dealcoholized type one-component RTV silicone rubber with conducting filler preparation, has splendid heat trnasfer, heat dispersion.
In addition, also will illustrate, in Fig. 2, in order to each parts, structure show more directly perceived, upper half part of sectional drawing has installed thermal conductivity colloidal silica 7, and lower half portion does not install thermal conductivity colloidal silica 7.
The utility model heat radiating type automobile bearing, interior thermal conductivity colloidal silica 71 directly contacts with rolling element 4, so, outer race 2 and the fricative heat of rolling element 4 can be attached on interior thermal conductivity colloidal silica 71, and be delivered to rapidly on outer thermal conductivity colloidal silica 72 by thermal conductor 8, realize heat to shift to Bearing outer from Bearing inner rapidly, thoroughly, and dissipate eventually through air, whole bearing good heat dissipation effect, long service life; , directly contacted with rolling element 4 by hot colloidal silica meanwhile, can also effectively reduce the noise produced because of friction.
The above is enlightenment according to embodiment, and by above-mentioned description, relevant staff in the scope not departing from this invention thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its scope protected according to right.
