The invention discloses a kind of cooling water channel structures being connected with motor stator, including casing, stator, water cooling runner and pipe fitting, the water cooling runner is tubular structure, inlet is equipped on water cooling runner, liquid outlet and spiral helicine cooling water flow conduits, positioning step is equipped on the inner wall of casing, water cooling runner is placed in casing, and the bottom of water cooling runner contacts on positioning step, stator is arranged in water cooling runner, and it is interference fitted between stator and water cooling runner, two pipe fittings both pass through the side wall of casing and correspondence is threaded on the inlet and liquid outlet of water cooling runner.The present invention is good with stator silicon steel sheet elastic conjunction before stator coil is placed in silicon steel film trap using water cooling runner as an independent component, because cooling water channel is closely sized to stator shaft orientation, does not constitute influence for the placement of stator coil.
Description
Technical field:
The present invention relates to a kind of cooling water channel structures being connected with motor stator.
Background technique:
Recirculated water cooling is that motor commonly cools down means, by the way that runner is arranged on motor casing, is made in cooling water takes away
Portion is transmitted to the heat of casing outer surface, to achieve the purpose that stator cooling.
Runner is usually realized just like under type: 1, the pre-buried good circulating line before casing pours；2, direct using profile
It obtains；3, the water cooling runner of screw type is processed in blank material using the means of removal material, then splicing is made.
Directly by water cooling runner design when on motor casing, then the end maximum outer circle of stator coil is required to be less than in casing
Diameter, and retain suitable insulation distance.The occasion that end turn has particular/special requirement is faced, such as: for end turn axial direction ruler
It is very little to require, and radial dimension does not require.In this case, it is desirable that the outer circle of end turn has to be less than in motor casing
Diameter, and possess appropriate safe distance, otherwise motor stator cannot achieve assembly.If the size of end turn is greater than in casing
Diameter needs additionally to be arranged step structure then on motor casing to concede assembly space.
Summary of the invention:
The present invention is to provide a kind of cooling being connected with motor stator to solve the above-mentioned problems of the prior art
Channel structure.
The technical solution adopted in the present invention has: a kind of cooling water channel structure being connected with motor stator, including casing, fixed
Son, water cooling runner and pipe fitting, the water cooling runner are tubular structure, and inlet, liquid outlet and spiral shell are equipped on water cooling runner
The cooling water flow conduits for revolving shape are equipped with positioning step on the inner wall of casing, and water cooling runner is placed in casing, and the bottom of water cooling runner
Portion contacts on positioning step, and stator is arranged in water cooling runner, and is interference fitted between stator and water cooling runner, and two pipes connect
Head both passes through the side wall of casing and correspondence is threaded on the inlet and liquid outlet of water cooling runner.
Further, the junction of the pipe fitting and casing is equipped with sealing ring.
Further, the water cooling runner is made of stainless steel or aluminium alloy.
Further, the casing is made of carbon steel or cast iron.
Further, transition fit or clearance fit between institute's water cooling runner and casing.
The invention has the following beneficial effects: the present invention using water cooling runner as an independent component, in stator coil
It is good with stator silicon steel sheet elastic conjunction before placing in silicon steel film trap, because cooling water channel is closely sized to stator shaft orientation,
Influence is not constituted for the placement of stator coil.
Detailed description of the invention:
Fig. 1 is structure of the invention figure.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
Such as Fig. 1, a kind of cooling water channel structure being connected with motor stator of the present invention, including casing 1, stator 2, water cooling runner
3 and pipe fitting 4, water cooling runner 3 is tubular structure, and inlet, liquid outlet and spiral helicine cooling water are equipped on water cooling runner 3
Runner 31 is equipped with positioning step 11 on the inner wall of casing 1, and water cooling runner 3 is placed in casing 1, and the bottom of water cooling runner 3 is supported
It touches on positioning step 11, stator 2 is arranged in water cooling runner 3, and is interference fitted between stator 2 and water cooling runner 3, two pipes
Connector 4 both passes through the side wall of casing 1 and correspondence is threaded on the inlet and liquid outlet of water cooling runner 3.Pipe fitting 4 and fixed
Position step 11 jointly positions water cooling runner 3.
To guarantee leakproofness, sealing ring is equipped in the junction of pipe fitting 4 and casing 1.
The present invention is using water cooling runner as an independent component, and fixed before stator coil is placed in silicon steel film trap
Sub- silicon steel sheet elastic conjunction is good, because cooling water channel is closely sized to stator shaft orientation, for the placement not structure of stator coil
At influence.
After stator coil placement, motor stator is installed together with water cooling runner into motor casing.After the installation is completed,
Pipe fitting is passed through to the through-hole reserved on motor casing, is connect with the pipe screw thread on water cooling runner, and is subject to O-ring sealing, i.e., it is complete
At the connection with extraneous pipeline.
Water cooling runner is individually processed, and is made of stainless steel or aluminium alloy.
Casing 1 is made of carbon steel or cast iron, advantage of lower cost, and the material that rustless property is slightly weak, because of cooling water
Circulation path in, it is unrelated with motor casing, thus for the antirust of motor casing require decrease.
As previously mentioned, motor stator and water cooling runner are elastic conjunction, to guarantee to radiate, and water cooling runner and casing are matched
Conjunction then no longer needs to be interference fitted, it can be provided the cooperation in transition fit or gap is with convenient for assembly.
Water cooling runner reduces material and requirement on machining accuracy for motor casing independently of motor casing, while also reducing line
Enclose influence of the end size for motor casing internal diameter.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention
Protection scope.
