Abstract
The utility model relates to a mining explosion-proof three-phase asynchronous motor with small volume and big power, in particular to a water-cooling structure of motor, wherein cooling water channels are arranged on front and rear end covers and a frame of a motor, and the water channels of the front and the rear end covers are connected with the water channel of the frame in series to form a cooling water way. The cooling water channel of the frame comprises three parts which are respectively closed, namely a part connected with the cooling water channel of the front end cover, a part connected with the cooling water channel of the rear end cover, and a part of the cooling water channel of the frame. The water-cooling structure of motor has the advantages and active effects that the water channels of the front and the rear end covers are connected with the water channel of the frame in series to form the cooling water way, thereby simplifying the cooling structure of the motor and a cooling-water supplying system of a coal mine machines. Under the condition that a cooling-water supplying system of a coal machine is in normal work, the state of short-term damages of a motor bearing can be effectively avoided.
Description
Technical field
The utility model relates to flame-proof mine small-volume large-power threephase asynchronous, is a kind of water cooling structure of motor specifically.
Background technology
The drive motors of plant equipment under the coal mine, because the underground work environment is abominable, ventilation condition is bad, directly influences motor radiating.And to motor want that cube is little, power is big and the operating mode of continuous duty, all motor being exerted oneself as coal-winning machine, conveyer and development machine requires very highly, this kind operating mode directly causes motor to produce high heat, therefore support water-cooling structures that adopt more.But because underground working complexity, the flame-proof mine threephase asynchronous is the closed structure motor, inner thermal field belongs to three heat source temperature fields, the motor stator and rotor all produce high heat, though adopt the motor of support water-cooled can take away most of heat that stator produces, motor cavity and temperature of rotor are still very high, and by modes such as convection current, radiation and conduction heat are passed to bearing chamber, cause the bearing grease deterioration failure, finally cause the motor bearings short-term to be damaged.
The utility model content
At above-mentioned technical problem, the purpose of this utility model provides a kind of motor cooling structure that can effectively avoid the motor bearings short-term to damage.Concrete scheme of the present utility model is:
A kind of water cooling structure of motor, forward and backward end cap of motor and support all are provided with cooling water channel, and the forward and backward end cap water channel of described motor is contacted mutually with the support water channel, forms a cooling water channel.
Described support cooling water channel comprises three parts that each is self-enclosed, is respectively the part that links to each other with the front end housing cooling water channel, the part that links to each other with the rear end cap cooling water channel, and support cooling water channel part.
Described support cooling water channel three part water channels adopt inside and outside water jacket Welding Structure, and the inner water sleeve surface is welded with the baffling muscle, cooperate with outer water jacket to form cooling water channel.
Cooling water is entered by the part water inlet tap that described support cooling water channel links to each other with the front end housing cooling water channel, the front end housing of flowing through, support cooling water channel, rear end cap, and the faucet of part flows out after described support cooling water channel links to each other with the rear end cap cooling water channel.
The good effect of advantage of the present utility model and generation: the forward and backward end cap water channel of motor is contacted mutually with the support water channel, forms a cooling water channel, has simplified the cooling water system of the cooling structure and the coal mine machinery of motor.Under the situation of coal machine cooling water system operate as normal, the situation that can effectively avoid the motor bearings short-term to damage.

Fig. 2 is the utility model water-cooling structure expanded view.
Embodiment
Specify the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model structure comprises rear end cap 1, front end housing 6 and support cooling water channel, described support cooling water channel comprises support inner water sleeve 3, the outer water jacket 2 of support and baffling muscle 4, electric machine stand adopts inside and outside water jacket Welding Structure, support inner water sleeve 3 surfaces are welded with baffling muscle 4, cooperate with the outer water jacket 2 of support to form cooling water channel.
As shown in Figure 2, described support cooling water channel comprises three parts that each is self-enclosed, be respectively A: the part that links to each other with front end housing 6 cooling water channels, C: the part that links to each other with rear end cap 1 cooling water channel, B: support cooling water channel part, described A, B, C partly each have intake-outlet, wherein, A part water inlet 5 connects cooling water, A section port 21 connects front end housing water inlet 10, and front end housing delivery port 8 connects B part water inlet 14, and B part delivery port 23 connects rear end cap water inlet 12, rear end cap delivery port 13 connects C part water inlet 22, and C part delivery port 7 is total delivery port.
Like this, the forward and backward end cap of motor all adopts water-cooling structure, uses Welding Structure to form water annulus in the motor bearings outside, cooling water channel of the common formation of motor front and rear cover water channel and support water channel, when the motor operate as normal, forward and backward end cap and support can constitute the recirculated cooling water road.
