(12) on, both ends be equipped with cooling water cage plate (6), shaft cooling tube (4) one end by shaft hole (11) be placed in shaft carry out it is cold
But.
Particularly, crash roll is equipped between annulus water jacket (3) and stator water jacket slot (12), and between annulus water jacket (3)
It is connected to by annulus crosspiece (5).
Particularly, there are a water inlet (1) and water outlet (2), water inlets multiple in this way on each annulus water jacket (3)
(1) can be improved the speed that cooling water enters cooling jacket, multiple water outlets (2) can quickly discharge temperature have built up it is cold
But water.
Particularly, point-blank, the center of multiple water outlets (2) is similarly one at the center of multiple water inlets (1)
On straight line, meanwhile, the center at the center and annulus crosspiece (5) of each water outlet (2) and water inlet (1) is point-blank.
Particularly, both ends cooling water cage plate (6) connect and communicates with annulus water jacket (3), is capable of increasing cooling water in this way
Circulation path and area, improve cooling efficiency.
Further, shaft cooling tube (4) one end is connected to cooling water cage plate (6), and the other end is entered by shaft hole to be turned
Axis.
It is cold that the utility model using the effect that such cooling jacket heat sink conception is realized is that multiple water inlets (1) shorten
But water enters the time of cooling jacket；Multiple water outlets (2) improve the speed of the higher cooling water discharge cooling jacket of temperature；
Connected by annulus crosspiece (5) connection and cooling water cage plate (6) by both ends annulus water jacket (3) between each annulus water jacket (3)
The logical circulation path and circulation area for increasing cooling water, reaches good heat dissipation effect close to rotor well；Shaft is cooling
Pipe (4) further improves the cooling radiating efficiency of cooling jacket inside motor.

Specific embodiment
It is specifically clear in order to have the characteristics of those skilled in the art are to the utility model, effect and programme of work
Understand, the utility model combination attached drawing is described further below.
Fig. 1,2 be that the assembly of the water jacket cooling structure and rotor of a kind of medium-sized high pressure asynchronous motor of the utility model is shown
Be intended to, the center of water inlet (1), which is located in a straight line, in figure is conducive to cooling water in this way and enters cooling jacket, while it is multiple enter
The mouth of a river (1) is located at right above the space of cooling jacket；Water outlet (2) center is similarly positioned on straight line, multiple water outlets
