Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in figures 1-4: an efficient motor stator end oil distribution structure comprises a stator structure 1 and a shell 2; the outer wall of the stator structure 1 is provided with a plurality of oil spraying grooves 11; the oil spray groove 11 and the inner wall of the casing 2 form an oil passage 12. After the oil duct is formed between the oil spraying groove and the inner wall of the shell, the cooling oil added into the oil duct can be sprayed out from the two ends of the oil duct, the end windings 13 at the two ends of the stator structure can be cooled by the sprayed cooling oil, and a good heat dissipation effect can be achieved.
The inner wall of the shell 2 is provided with an arc-shaped groove 21 along the circumferential direction; an oil inlet 22 on the side wall of the machine shell 2 is communicated and connected with the plurality of oil passages 12 through an arc-shaped groove 21. The cooling oil that gets into from the oil inlet flows to the arc wall in, then through the arc wall decentralized flow to a plurality of oil ducts, on cooling oil spouts the end winding 13 at stator both ends to oil duct both ends, just so can cool off the heat dissipation.
The arc-shaped groove 21 is of a C-shaped structure, so that the wall thickness of the machine shell is increased in order to avoid an interference area, the strength is increased, and the damage to the machine shell is reduced.
The arc-shaped groove 21 is perpendicular to the oil ducts 12, so that cooling oil can be uniformly distributed in each oil duct, and can be uniformly distributed at two ends of each oil duct, and cooling of the end winding 13 is facilitated.
The arc-shaped grooves 21 are communicated in series around the oil passages 12, and the arc-shaped grooves 21 are located in the middle of the oil passages 12. The cooling oil enters from the middle of the oil passage and then flows to both ends to be sprayed out to cool the end winding 13.
The shell 2 is transversely placed, and six equal areas in the circumferential direction of the shell 2 are uniformly distributed and comprise an area A01, an area B02, an area C03, an area D04, an area E05 and an area F06. The area A01, the area B02, the area C03, the area D04, the area E05 and the area F06 are arranged in a surrounding mode in the clockwise direction, the area A01 is located at the top of the machine shell 2, the area E05 is an interference area, an arc-shaped groove is not formed in the area E, the wall thickness of the machine shell at the position of the interference area is increased, and strength is improved. The interference area position can set up the oil duct and also can not set up the oil duct, and when seting up the oil duct, the cooling oil of tip winding 13 position can flow in the oil duct of interference area position, and the cooling oil can flow circulation like this, also plays certain effect to the cooling of stator structure lateral wall simultaneously, has promoted the heat dissipation to tip winding 13.
The arc-shaped groove 21 is correspondingly positioned in the area A01, the area B02, the area C03, the area D04 and the area F06, and the oil inlet 22 is arranged corresponding to the middle of the area A01. The cooling oil enters the area A from the oil inlet and then is divided into two flow directions, one flow direction passes through the area B02, the area C03 and the area D04, and the other flow direction passes through the area F06, so that the cooling oil correspondingly flows into corresponding oil passages in each area and is sprayed out from two ends of the oil passages.
The number distribution that spouts oil groove 11 corresponds A district 01, B district 02, C district 03, D district 04 is x +3, x +2, x +1 and x, just spout the quantity that oil groove 11 corresponds B district 02 more than or equal to spout the quantity that oil groove 11 corresponds F district 06. The number of oil passages through which the two flows of cooling oil pass is different, and the number of the first flow of cooling oil passing through the B area 02, the C area 03 and the D area 04 is large, so that more cooling oil needs to pass through, and the cooling oil is more uniformly distributed.
From the top oil inlet 22 of the machine shell 2 to the two ends of the arc-shaped groove 21 downwards, the size of the oil spraying groove 11 is gradually reduced. After cooling oil enters from the oil inlet, because the cooling oil has a certain impact flow rate and a gravity factor, the cooling oil flows downwards and fills the oil passage at the lower part, so that the oil spraying groove at the top of the stator structure is not enough to spray enough cooling oil to cool the end winding 13, and the number of the oil spraying grooves at the bottom of the stator structure needs to be correspondingly reduced or the size of the oil spraying groove at the bottom of the stator structure needs to be correspondingly reduced; can form certain resistance to the oil duct of stator structure bottom like this, can do benefit to the oil duct that the cooling oil also can fill the stator structure top like this, reach the effect of fine even oil distribution, just so can the oil duct of stator structure top and bottom can both play fine cooling radiating effect to end winding oil spout cooling.
The above description is of the preferred embodiment of the present invention, and it will be apparent to those skilled in the art that several modifications and variations can be made without departing from the principles of the invention, and these modifications and variations are considered to be within the scope of the invention.
