Abstract
The utility model relates to a kind of mixed flow ventilation self-lubricating reduce motor bearings temperature rise structure, it by: fan guard, wind deflector, fan, sliding bearing, rotor, base, water-output flange, radiating fin, cooling water pipe, water-in flange are constituted.Fan guard is mounted on base, and fan is mounted on the rotor, and wind deflector is mounted on fan guard, sliding bearing is fixed on base, and cooling water pipe is mounted in sliding bearing, and radiating fin is embedded on cooling water pipe, cooling water pipe one end is equipped with water-in flange, and the other end is equipped with water-output flange.The product it be that an aerofoil fan and wind deflector are installed on the outside of bearing, bearing surface heat is taken away by accelerating air flowing, simultaneously by adding cooling water pipe in Bearing inner, outside is that user reserves flange-interface, Bearing inner heat is taken away by external cooling circulating water, good heat dissipation effect not will lead to the raising of internal fan side bearing temperature, improve the service life of motor.
Description
Technical field
The utility model relates to the structures that a kind of ventilation self-lubricating of mixed flow reduces motor bearings temperature rise.
Background technique
Currently, respectively radial ventilation structure and mixed flow are logical both at home and abroad there are mainly two types of high pressure square chest motor ventilation structures
Wind structure, most of motors mostly use mixed flow aeration structure, and mixed flow aeration structure biggest advantage is motor inner and outer temperatures field
Sufficiently, cooling effect of motor is good, but the axial-temperature gradient of integrated motor changes greatly, and internal fan side bearing temperature for heat exchange
It is relatively higher, especially for sliding bearing self-lubricating structure, due to belonging to linear friction, friction system between sliding bearing and axis
Number is big compared with rolling bearing, so generated energy is also bigger than rolling bearing, simultaneously because self-lubricating structure, heat is only capable of by bearing certainly
Body radiates, and enforced lubricating can then be taken away most of heat by lubricating oil, along with the influence of motor inside hot wind, into
One step causes internal fan side bearing temperature to increase, and makes oil film breakdown, burning in of bearing, burns out a bearing and rotor.
Summary of the invention
The purpose of the utility model is to overcome disadvantages mentioned above, provide a kind of mixed flow ventilation self-lubricating reduction motor bearings temperature
The structure risen, it is mainly solved, and mixed flow ventilation self-lubricating motor internal fan side bearing temperature is high, and heat is only capable of by bearing certainly
Body radiates, and will lead to oil film breakdown, burns out a bearing and the problems such as rotor.The purpose of this utility model is achieved in that
A kind of ventilation self-lubricating of mixed flow reduce the structure of motor bearings temperature rise by: fan guard, wind deflector, fan, sliding bearing, rotor,
Base, water-output flange, radiating fin, cooling water pipe, water-in flange are constituted.Fan guard is mounted on base, and fan, which is mounted on, to be turned
On son, wind deflector is mounted on fan guard, and sliding bearing is fixed by bolts on base by seam allowance, and cooling water pipe is mounted on cunning
In dynamic bearing, radiating fin is embedded on cooling water pipe, cooling water pipe one end is equipped with water-in flange, and the other end is equipped with water-output flange.
It is that an aerofoil fan and wind deflector are installed on the outside of bearing to the product, takes away bearing surface heat by accelerating air flowing
Amount, while by adding cooling water pipe in Bearing inner, outside is that user reserves flange-interface, will by external cooling circulating water
Bearing inner heat is taken away, tests prove that 25-30 DEG C of sliding bearing temperature can be effectively reduced, good heat dissipation effect will not be led
It causes internal fan side bearing temperature to increase, improves the service life of motor.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram that a kind of mixed flow ventilation self-lubricating of the utility model reduces motor bearings temperature rise.
Attached drawing 2 is that a kind of mixed flow ventilation self-lubricating of the utility model reduces inside the structure sliding bearing of motor bearings temperature rise
Structural schematic diagram.

6-base 7-water-output flange, 8-radiating fin, 9-cooling water pipe, 10-water-in flanges
Specific embodiment
The most preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings, a kind of mixed flow ventilation self-lubricating reduction motor
The structure of bearing temperature rise is by fan guard 1, wind deflector 2, fan 3, sliding bearing 4, rotor 5, base 6, water-output flange 7, radiating fin
Piece 8, cooling water pipe 9, water-in flange 10 are constituted.Fan guard 1 is mounted on base 6, and fan 3 is mounted on rotor 5, wind deflector 2
It is mounted on fan guard 1, sliding bearing 4 is fixed by bolts on base 6 by seam allowance, and cooling water pipe 9 is mounted on sliding bearing 4
It is interior, radiating fin 8 is embedded on cooling water pipe 9,9 one end of cooling water pipe is equipped with water-in flange 10, and the other end is equipped with water-output flange 7.
Working principle: when motor operation rotation, in the wind to sliding bearing 4 of fan 3, playing the role of heat dissipation, sliding
The heat in sliding bearing 4 is taken away by the cold water that cooling water pipe 9 flows into inside dynamic bearing 4, further functions as cooling work
When with, installation, aerofoil fan 3 after the installation is completed, is mounted on an axle by bearing first, and wind deflector 2 is then fixed on wind
Fan covers on 1, then fan guard 1 is fixed on electric motor end cap, is loaded on shield, water-output flange 7 and cooling water pipe 9 are welded
It is connected into one, radiating fin 8 fills bearing on cooling water pipe 9, then by water-output flange 7, cooling water pipe 9,8 entirety of radiating fin
It is interior, water-in flange 10 is finally installed.
