Embodiment
Embodiment:A kind of bearing tile structure, including wearing layer 1, tile fragment supporter 2 and heat dissipating layer 3, the heat dissipating layer 3
It is fixedly installed in by connector 4 on the side surface of tile fragment supporter 2 one, wearing layer 1 is fixed and is covered in the dorsad tile fragment branch of heat dissipating layer 3
On the side surface of support body 2 one.
Heat dissipating layer 3 is fixedly mounted on the side of tile fragment supporter 2 by connector 4, it is to avoid using hot pressing and the group of sintering
Dress mode, greatly reduces the requirement to process equipment and the material of heat dissipating layer 3, reduces processing cost, improve stable connection
Property, the radiating effect in the bearing tile course of work is improved, the bearing capacity and service life of bearing is greatly improved.
The connector 4 is one or more combinations in screw, rivet, buckle, pin.
The heat dissipating layer 3 is consistent with the profile of tile fragment supporter 2, and some screwed holes, heat dissipating layer are distributed with tile fragment supporter 2
3 be provided with countersunk head through hole corresponding with the upper screwed hole position of tile fragment supporter 2, screw through heat dissipating layer 3 countersunk head through hole and with
Screw hole on tile fragment supporter 2, the head of screw is just placed in the countersunk head of heat dissipating layer 3 completely.
It is fixed together between the heat dissipating layer 3 and wearing layer 1 by back-off structure 5 or sintering structure, by falling
The mode of buckle structure 5 or sintering realizes the connection of heat dissipating layer 3 and wearing layer 1, stable connection, the two accurate positioning.
The back-off structure 5 is distributed in heat dissipating layer 3 and the corresponding side wall surrounding of wearing layer 1, and the surrounding of heat dissipating layer 3 needs
There is back-off structure 5, the wearing layer 1 that is placed on of purpose comes off, tried one's best if space and design some back-offs more.
