Abstract
The utility model relates to a cooling water circuit sealed structure for a motor outer cover. The structure abrogates a hook-shaped groove that is arranged at one side of an envelope, and changes the hook-shaped groove to a semi side structure that is equal to the outer cover. The utility model has two end caps at the two ends at the bottom cushion of the groove through a glue shaped gasket, and presses down the glue-shaped gasket with the end caps to make the gasket stretch and deform to plug all the space of the groove and further seal the seam. If necessary, a sealant can be coated onside. By using the structure, the materials are reduced and the volume of the motor is also lessened; furthermore, the technique is very simple and the quantity production is prone to be realized.
Description
[technical field]
The utility model relates to a kind of motor housing, refers more particularly to a kind of hermetically-sealed construction of motor housing cooling water channel.
[background technology]
Present motor water cooling stator cage hermetically-sealed construction is promptly made hook-shaped structure at A, B two places with it as shown in Figure 1, and the end of one of casing and big envelope is propped up channel bottom, coats the fluid sealant sealing then, forms a sealing device.Wherein the hook-shaped structure at A place will process on big envelope.Big envelope directly is sleeved on the outer surface of casing, guarantees that simultaneously A, B two place's fins cooperate with groove.
But this technology has the following disadvantages: on the one hand, because big envelope is thinner, mill out the hook-shaped groove in bottom, waste material is more, and is difficult for processing; On the other hand, in order to match with big envelope, the casing end also needs to process groove, has increased casing external diameter and volume, and two ends all will cooperate difficult assembling.
[utility model content]
Technical problem to be solved in the utility model provides a kind of energy economical with materials, and process easily, the while can reduce the motor housing cooling water channel hermetically-sealed construction of casing volume again.
For solving the problems of the technologies described above, the motor housing cooling water channel hermetically-sealed construction that the utility model provides comprises big envelope and casing, and described casing outer surface has circulation waterway, and described casing left end and big envelope all have seal groove.
As a kind of improvement of the present utility model, seal groove is a semicircular structure, and casing left end and big envelope are combined and formed a circular recess.
The another kind novel as this use improves, and the casing two ends are provided with flexible device, are mainly glue shape packing ring, utilize end cap to compress glue shape packing ring, fill up the ditch slot space with gap sealing thereby make it dilatation.
Advantage of the present utility model is: this structure not only can economical with materials, reduce motor volume, and technology is simple, realizes mass production easily.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the profile of existing motor housing cooling water channel hermetically-sealed construction;
Fig. 2 is the profile of the utility model motor housing cooling water channel hermetically-sealed construction.
[embodiment]
As shown in Figure 2, after high-temperature water enters from water inlet, form a circulation, high-temperature water flows in this circulation, thereby cooling gradually flows into delivery port again.Because the special construction of groove, and the effect of glue shape packing ring and fluid sealant, water well is sealed in the groove, has realized the effect of sealing.
As shown in Figure 2, earlier right seal washer 4 is filled up in the right groove of casing 5, stamp some fluid sealants, make its sealing; Again big envelope 3 cover is installed to casing 5 outsides, at this moment will note cooperating of big envelope 3 right-hand members and casing 5 grooves, and compress right seal washer 4.At this moment, half groove of half groove of big envelope 3 left ends and casing 5 left ends is combined into a whole groove, the left seal washer 2 of packing in this groove, stamp some fluid sealants again, compress end cap 1, and end cap 1 and casing 5 are tightened, need to guarantee the applying of end cap 1 bottom surface and casing 5 and big envelope 3 end faces simultaneously with bolt 6.
For the latter half of casing, also adopt and use the same method, make it reach same effect.
Claims (5)
1, a kind of motor housing cooling water channel hermetically-sealed construction comprises big envelope and casing, and described casing outer surface has circulation waterway, it is characterized in that: described casing left end and big envelope all have seal groove.
2, motor housing cooling water channel hermetically-sealed construction according to claim 1, it is characterized in that: described seal groove is a semicircular structure.
3, motor housing cooling water channel hermetically-sealed construction according to claim 2, it is characterized in that: described casing two ends are provided with flexible device.
4, motor housing cooling water channel hermetically-sealed construction according to claim 3 is characterized in that: described elastic element is a glue shape packing ring.
5, motor housing cooling water channel hermetically-sealed construction according to claim 1 and 2 is characterized in that: in the described seal groove fluid sealant is arranged.
