The motor of revolving speed spline output, tooling need bearing just to guarantee the steady operating of transmission shaft, and bearing, which runs at high speed, can generate very
High heat, bearing are run at high temperature for a long time, be will lead to the lost of life of bearing, are made bearing premature deterioration, and bearing
Damage will lead to more heats if finding not in time again and generate, and will lead to bearing locking if serious, and transmission shaft damage is real
Test interruption.
The utility model aims to solve the problem that the technical problems existing in the prior art, for this purpose, propose a kind of bearing radiating structure,
Heat exchange area is increased by multiple groups aluminum thermal fin, aluminum thermal fin is by heat derives and is dispersed into outside air, makes
The efficiency that must be radiated dramatically increases, and realizes the real-time heat dissipation in bearing use, avoids bearing locking, guarantees stable operation, realizes
Fast cooling after bearing use eliminates accumulated heat cracking issues.
Utility model content
The purpose of this utility model is to provide a kind of bearing radiating structures, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions:
A kind of bearing radiating structure, including the horizontally disposed transmission shaft in middle position, the outer, coaxial water of the transmission shaft
Flat to be provided with bearing block, the outside right end of bearing block is provided with fixed installation ring, outside the bearing block being fixedly mounted on the left of ring
Side is equidistantly vertically arranged with several cooling fins, and the inside both ends cooperation transmission shaft of the bearing block is symmetrically arranged with bearing.
As a further solution of the present invention: the cooling fin is made of aluminium.
Axis is provided with as a further solution of the present invention: being located on the position between two bearings on the outside of transmission shaft
Hold positioning bushing.
As a further solution of the present invention: being filled with bearing between the bearing positioning bushing and bearing

Embodiment one
Please refer to Fig. 1~3, in the utility model embodiment, a kind of bearing radiating structure, including middle position are horizontally disposed
Transmission shaft 1, the outer, coaxial of the transmission shaft 1 is horizontally disposed bearing block 4, and the outside right end of bearing block 4 is provided with fixation
Mounting ring, 4 outside of bearing block being fixedly mounted on the left of ring are equidistantly vertically arranged with several cooling fins 5, the cooling fin 5
It is made of aluminium, the inside both ends cooperation transmission shaft 1 of the bearing block 4 is symmetrically arranged with bearing 2, the 1 outside position of transmission shaft
Bearing positioning bushing 6 is provided on position between two bearings 2,5 height of cooling fin is 20-50mm, with a thickness of 2-
6mm, adjacent two cooling fin 5 away from for 4-10mm.
It is several by being installed on the outside of bearing block 4 in order to solve the heat dissipation problem after bearing 2 runs at high speed and stalls
Aluminum thermal fin 5, so that internal heat quickly exports, band dynamic bearing 2 rotates when specially transmission shaft 1 rotates, and bearing 2 produces
Raw heat is dispersed into outside air by bearing block 4 and cooling fin 5, since multiple groups aluminum thermal fin 5 increases heat exchange
Area realizes the real-time heat dissipation in 2 use of bearing so that the efficiency of heat dissipation dramatically increases, and avoids 2 locking of bearing, guarantees to stablize
Operation, the fast cooling after realizing 2 use of bearing, eliminates accumulated heat cracking issues.
Embodiment two
On the basis of example 1, bearing lubrication has been filled between the bearing positioning bushing 6 and bearing 2
Rouge 3 realizes that the coefficient of friction of the rotation operation of bearing 2 reduces, reduces the heat that rotation generates by bearing lubricating grease 3, so that
Bearing 2 rotates more preferably, and heat production is less.
