Description
Technical field
Electric machine structure the utility model relates to a kind of axle stretch end with cooler, suitable for the special of steel mill's bar mill line
The frequency converting speed regulating three-phase asynchronous electromotor used under operating condition.
Background technique
With the rapid development of metallurgical technology, metallurgical equipment requires also higher and higher, most of smelting to its matched motor
The power of golden equipment is driven to variable-frequency motor from traditional ordinary motor acceleration and deceleration machine and directly drives metallurgical roller conversion, this to connect
Structure has many advantages, such as that equipment speed adjustable range is wide, structure is simple, and equipment takes up space small.But this structure have one it is universal
The shortcomings that be exactly: the amount of heat generated in the course of work is directly passed to the shaft of motor, makes the temperature of shaft is excessively high to burn
Motor bearings, the motor of the common type of cooling are unable to satisfy the requirement of operating condition again.Cover drive roller on motor-shaft extending, roller when operation
Sub- surface temperature is quite high and transfers heat to the axis of motor quickly and stretches, if stretching the heat passed over to the axis of motor
The lubricating oil of uncontrolled axle stretch end bearing will soon be dried, and the service life of such bearing will be influenced by serious.
Summary of the invention
The purpose of this utility model is to design a kind of electric machine structure of the axle stretch end with cooler, solves this problem, cooling
The function of device be exactly the heat on motor-shaft extending is dispersed into a short period of time in the air of surrounding, this requires that it
There is good heat exchange performance.
The technical solution of the utility model includes: a kind of axle stretch end of the utility model includes motor with the electric machine structure of cooler
Rotor, stator, base, flange end cap set cooler installation cavity, the rotor axis of electric in cooler installation cavity in flange end cap
Upper installation cooler has air inlet and air outlet on the shell of cooler installation cavity.
The cooler installation cavity is to lengthen flange end cap, is hollowed out on the inside of flange end cap middle section, with rotor
Forming cavity between axis, the front end of flange end cap is hatch frame, there is outer cover for closure of openings in the front end outer side of flange end cap,
Form cooler installation cavity, length L=130~135mm of flange end cap.
The cooler includes axle sleeve and the cooling fin that is connected on axle sleeve, and sleeve diameter is matched with rotor axis of electric；
Cooling fin every with a thickness of 2mm, the radial height of cooling fin (8b) is 5mm, and the outer end periphery and cooler of cooler are installed
Distance between chamber cavity is 8~12mm.
The advantages of the utility model: (1) amount of heat generated on electric-machine directly-driven roller is transmitted to cold by motor-shaft extending
But on device, heat is distributed by cooler, to have the function that protect motor bearings normal use.
(2) scene has in the direct splash to motor of a large amount of cooling water in the online use process of motor, and cooler may be used also
It is thrown out with the water for playing the role of coming splash, improves motor degree of protection to reach.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the specific structure of cooler.
Fig. 3 is the left view of Fig. 2.
Specific embodiment
Fig. 1 is the structural schematic diagram of the utility model: the utility model includes rotor 1, stator 2, base 3, flange
End cap 4 sets cooler installation cavity 5 in flange end cap 4, installs cooler 8 on the rotor axis of electric in cooler installation cavity 5,
There are air inlet 6 and air outlet 7 on the shell of cooler installation cavity 5.
The cooler installation cavity 5 is to lengthen flange end cap 4, is hollowed out on the inside of 4 middle section of flange end cap, is turned with motor
Cavity is formed between sub- axis, the front end of flange end cap 4 is hatch frame, has outer cover 9 that will be open in the front end outer side of flange end cap 4
Closing forms cooler installation cavity 5, length L=130~135mm of flange end cap 4.Air inlet 6 and air outlet 7 are in cooler
Installation cavity section.
Fig. 2, Fig. 3 are the specific structures of cooler:
The cooler 8 includes axle sleeve 8a and the cooling fin 8b being connected on axle sleeve 8a, and axle sleeve 8a internal diameter and motor turn
Sub- axis matching；Cooling fin 8b every with a thickness of 2mm, the radial height of cooling fin 8b is 5mm, the outer end periphery of cooler with it is cold
But the distance between 5 cavity of device installation cavity is 8~12 mm.
In figure: having bearing 10, tank filler sleeve 11, outage 12, internal bearing cover 13, oil sealing 14, fan 15.
Cooler 8 selects alloy aluminum material.There are three types of the manufacture crafts of cooler:
First is that with the riveting of the aluminium sheets of 2 millimeters thicks it is integral after be mounted on axle sleeve or be welded on axle sleeve with key again, axle sleeve
Using cast alloy aluminium；It is formed second is that netted use butt-joint is made with the aluminium sheet of 2 millimeters thicks；Third is that axle sleeve and cooling fin are made into whole
Body is formed using die casting, and this technique is most simple, but its defect is exactly that cooling fin is thicker at least at 3 millimeters, be will affect in this way
Certain heat dissipation effect.
The core of the utility model is that cooler installation cavity is set in flange end cap, and the motor in cooler installation cavity turns
Cooler is installed on sub- axis, the big calorimetric generated on electric-machine directly-driven roller is transmitted on cooler by motor shaft, by cold
But device distributes heat, has the function that protect motor bearings normal use.Therefore, all motors in flange end cap
Cooler is installed on armature spindle, belongs to the protection scope of the utility model.
