Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further, it should be noted that Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new Embodiment.
As shown in Fig. 1~2, in order to improve the sealing performance of water-cooled machine, it is close that the utility model provides a kind of water-cooled machine Seal structure, the structure include shell 10, stator 20 and rotor 30;It is formed in shell 10 for accommodating stator 20 and rotor 30 Motor cavity 11;Stator 20 is fixed in motor cavity 11 and is matched with rotor 30;Rotor 30 is coaxially connected with shaft 40, shaft 40 one end extends outwardly along the rotation axis direction of rotor 30 and is pierced by shell 10, under the action of stator 20 and rotor 30, Rotor 30 drives shaft 40 to convert electrical energy into kinetic energy relative to the rotation of shell 10.The both ends of shell 10 be covered with respectively for Shell 10 is formed together the upper end cover 50 and bottom end cover 60 for enclosing motor cavity 11;Cooling water cavity 12, upper end cover are equipped in shell 10 50 and bottom end cover 60 be respectively equipped with cooling water cavity 12 be interconnected cooling water channel 70;Upper end cover 50 and bottom end cover 60 are also distinguished Equipped with the water inlet 61 and water outlet 51 being connected to cooling water channel 70;One end that cooling water cavity 12 is connected with two cooling water channels 70 It is fixed with sealing element 1213;Cooling water cavity 12 is equipped with the end of two cooling water channels 70 to connect for limiting 1213 shape of sealing element The locating part 1214 of change and displacement.
Due to being sequentially connected and drawing again by interconnected cooling water channel 70 and cooling water cavity 12 inside water-cooled machine Enter flow and cooling, therefore the leakproofness of the junction between shell 10 and upper end cover 50, bottom end cover 60 are carried out to shell 10 Can be particularly critical, by the company for improving the cooling water channel 70 in upper end cover 50 and bottom end cover 60 and the cooling water cavity 12 in shell 10 Connect sealing structure, to improve the sealing performance of water-cooled machine, avoid water-cooled machine in use by external environment influence with It is penetrated into wherein by water or inside is seeped water outward or into motor cavity 11, by the connecting pin of cooling water cavity 12 and cooling water channel 70 Sealing element 1213 is set, obstructs the gap of the connecting pin of cooling water channel 70 and cooling water cavity 12, then by locating part 1214 to close Sealing 1213 limited and provided 1213 deformation direction of sealing element it is opposite support power, prevent sealing element 1213 from using Deformation and displacement in journey, greatly improve the sealing performance between cooling water cavity 12 and cooling water channel 70.
In order to further increase upper end cover 50 and bottom end cover 60 sealing performance between shell 10 respectively, 50 He of upper end cover Bottom end cover 60 is respectively provided with the tenon position platform 80 with the positioning clamping of shell 10, and tenon position platform 80 can make upper end cover 50 and bottom end cover 60 Accurately positioning clamping relationship is formed between shell 10 respectively, is passing through fixed sealing between two tenon position platforms 80 and shell 10 Ring is to block the inside and outside of water-cooled machine.
Even closer in order to make to connect between cooling water cavity 12 and cooling water channel 70, two cooling water channels 70 extend outwardly respectively It is useful for the runner being connect with cooling water cavity 12 71;The both ends of cooling water cavity 12 towards shell 10, which each extend over, to be useful for and two runners The sluice 121 of 71 connections.
Specifically, one end that two runners 71 are connected with sluice 121 offers first step 711 respectively;Sluice 121 with The connected one end of two runners 71 offers second step 1211 respectively;First step 711 is all higher than with 1211 diameter of second step Runner 71 and sluice 121, and diameter is equal, and fixed positioning chuck is embedded in for locating part 1214 to be formed;Second step 1211 end faces to connect with first step 711 are offered is embedded in fixed third step 1212 for sealing element 1213.
First step 711 is the cyclic structure opened up around 71 circumferential direction of runner;Second step 1211 is around sluice 121 The cyclic structure that circumferential direction opens up;Third step 1212 is the cyclic structure opened up around 1211 circumferential direction of second step, the Three steps, 1212 diameter is more than first step 711 and second step 1211.
More specifically, sealing element 1213 is sealing ring;Locating part 1214 is that circle covers;Sealing ring is embedded in third step 1212, It is fixed on first step 711 and second step 1211 by circle set insertion, so that third step 1212, circle set and upper end cover 50 Lower face and/or the upper surface of bottom end cover 60 form confined space for limiting sealing ring deformational displacement.
It, can be by the lower face of upper end cover 50 or the upper end of bottom end cover 60 after being mounted on third step 1212 due to sealing ring The compressing in face and third step 1212, to towards the 70 inside deformation expansion of cooling water channel for not having stationary plane, influence its sealing Effect, therefore, embedded circle set, opposite to be formed to sealing ring deformation direction on second step 1211 and first step 711 Power is supported, sealing ring deformation or displacement are prevented, ensures the sealing effect between cooling water cavity 12 and cooling water channel 70.
In order to further increase sealing performance between the shaft 40 of water-cooled machine and shell 10, bottom end cover 60, bottom end cover 60 40 periphery of interior twisted rotary shaft is equipped with machine sealing chamber 63, and two cavity walls up and down of machine sealing chamber 63 offer the axis hole stretched out for shaft 40 respectively 62;Be perfused with lubricating oil in machine sealing chamber 63, it is preferred that lubricating oil is transformer oil, between machine sealing chamber 63 and shaft 40 be equipped with The double mechanical seal part 631 that shaft 40 is coaxially disposed, the both ends stationary ring of double mechanical seal part 631 is respectively with upper and lower two Axis hole 62 is tightly connected;The revolving part of double mechanical seal part 631 is sheathed on shaft 40, transformer oil have pure stabilization, The features such as viscosity is small, good insulating, good cooling, therefore while heat radiation lubricating can be carried out to double mechanical seal part 631, Also it can further be sealed between axis hole 62 and motor cavity 11, preferable insulating properties makes transformer oil penetrate into motor cavity It will not lead to electric motor short circuit in 11.
As preferred embodiment, in order in the case where meeting water-cooled machine sealing performance, facilitate double mechanical The dismounting of sealing element 631 and the maintenance of machine sealing chamber 63, the bottom of machine sealing chamber 63 offer downward opening accent, and accent is removable The organic sealed cover of the joggle that unloads 64;Machine sealed cover 64 is equipped with axis hole 62;Machine sealed cover 64 and double mechanical seal part 631 Lower end stationary ring is affixed.Staff only needs can be to double mechanical seal part 631 and machine sealing chamber by demountor sealed cover 64 63 are replaced or are repaired.
Sealing ring is equipped between machine sealed cover 64 and bottom end cover 60.
The above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to In the utility model range claimed.
