Abstract
A kind of high temperature resistant bearing assembly, including, bearing holder (housing, cover), bearing, bearing shaft, thermal insulation layer, the bearing holder (housing, cover) fix the outer ring of the bearing；The bearing shaft fixes the inner ring of the bearing；The thermal insulation layer is located in the bearing holder (housing, cover) intermediate gaps.High temperature resistant bearing assembly of the invention makes each component on bearing assembly still be able to keep working normally in external high temperature by reducing the heat passed on bearing and bearing shaft.
Description
Technical field
The invention belongs to robotic technology fields, and in particular to a kind of resistance to height for fire-fighting robot and specialized robot
Warm bearing assembly.
Background technique
The one kind of fire-fighting robot as specialized robot plays very important work in fire extinguishing and rescue further
With.Various Large Scale Petrochemical Enterprises, tunnel, subway etc. are increasing, and oil product combustion gas, toxic gas leakage explosion, tunnel, subway collapse
The equal Hidden hazrads that collapse are continuously increased.Fire-fighting robot can replace fire-fighting and rescue personnel to enter inflammable and explosive, toxic, anoxic, dense smoke
The equal hazards scene of the accident carries out data sampling and processing, feedback.
Fire-fighting robot needs to enter hot environment operation, needs bearing that can work normally at high operating temperatures, to protect
Robot proper motion function in a high temperauture environment is demonstrate,proved, for example robot enters scene of fire scouting, its bearing must be resistance to
It by high temperature, and is able to bear compared with big load, guarantees robot proper motion in the scene of a fire.Existing bearing use environment temperature
It is lower, when high ambient temperature is higher, it is easily damaged failure, to influence the motor function of robot.
Summary of the invention
In order to solve the shortcomings of the prior art, the purpose of the present invention is to provide a kind of high temperature resistant bearing assembly, drops
The low heat passed on bearing and bearing shaft, so that each component on bearing assembly be made still to be able to maintain normal work in external high temperature
Make.
To achieve the above object, high temperature resistant bearing assembly provided by the invention, including, bearing holder (housing, cover), bearing, bearing shaft, every
Thermosphere, wherein
The bearing holder (housing, cover) fixes the outer ring of the bearing；The bearing shaft fixes the inner ring of the bearing；The thermal insulation layer
In the bearing holder (housing, cover) intermediate gaps.
Further, the high temperature resistant bearing assembly further comprises bearing outer ring retaining ring and bearing inner race retaining ring, described
Bearing holder (housing, cover) is fixed the outer ring of the bearing by the bearing outer ring retaining ring；The bearing shaft passes through the bearing inner race retaining ring
The inner ring of the bearing is fixed.
Further, the bearing holder (housing, cover) be width formula wheel hub structure, in the hub between be filled with the thermal insulation layer.
Further, there is gap at the bearing shaft and the bearing fit and be filled with red copper foil.
Further, there is gap at the bearing holder (housing, cover) and the bearing fit and be filled with red copper foil.
High temperature resistant bearing assembly of the invention, can reduce the heat passed on bearing and bearing shaft, to make bearing group
Each component is in external high temperature on part, additionally it is possible to keep working normally, protrude meaning and be: when robot is in hot environment
When work, bearing assembly can be worked normally.
Other features and advantages of the present invention will be illustrated in the following description, also, partly becomes from specification
It obtains it is clear that understand through the implementation of the invention.
Detailed description of the invention
