Abstract
The utility model relates to a sealing ring that is used for axial water course motor section bar casing. Including pancake annular seal ring body, the even interval arrangement in a side end face of sealing ring body has the boss, boss and water -cooling casing on the water course hole sealed mutually, the even interval arrangement of opposite side terminal surface of sealing ring body has annular first rib, first rib and end cover on the seal groove bottom surface that sets up sealed mutually. Can know that the novel sealed and end face seal of water course who passes through a sealing ring and can realize axial water cooled machine casing simultaneously of this reality has optimized the processing technology nature of water -cooling casing, has improved the cleanliness of water course, has reduced casing cost and motor total cost by above -mentioned technical scheme to the reliability of motor has been improved to a certain extent.
Description
Technical field
This reality is novel relates to a kind of sealing ring for axial water channel motor section bar housing.
Background technology
At present, the permagnetic synchronous motor of high power density typically uses the mode of water-cooled to cool down, axial water-cooled section bar housing relatively radially water channel housing has the advantages such as mould is simple, section bar quality is tight, water channel covering is more abundant, is the most increasingly widely applied at new-energy automobile electric control field.Using housing two ends water channel to fill solder the sealing of existing axial water-cooled housing to seal, welding uses argon arc welding more more, and cost is high, manufacturability is poor；Meanwhile, then seal parallel form by gluing and sealing ring between housing and end cap and realize, seal loaded down with trivial details.
Summary of the invention
The novel purpose of this reality is to provide a kind of sealing ring for axial water channel motor section bar housing, this sealing ring has been taken into account the water channel of conventional axial water-cooled motor shell and has been sealed and end face seal, optimize the processing technology of water-cooled housing simultaneously, improve the cleannes of water channel, reduce housing cost and motor assembly basis, and improve the reliability of motor to a certain extent.
For achieving the above object, the novel techniques below scheme that have employed of this reality: include pancake annular seal ring body, one side end face uniform intervals of described sealing ring body is disposed with boss, described boss seals mutually with the water channel hole on water-cooled housing, the opposite side end face uniform intervals of described sealing ring body is disposed with the first rib of annular, and described first rib seals mutually with the seal groove bottom surface of setting on end cap.
Described boss is disposed with the second rib along its circumference uniform intervals, and the cross sectional shape of described second rib is semicircle, and the second rib seals mutually with the inwall of water channel hole.
Described boss is overall to be arranged in arcuation, and the shape of boss matches with the shape of water channel hole, and the number that boss is arranged matches with the number of water channel hole.
The cross sectional shape of described first rib is semicircle.
As shown from the above technical solution, novel water channel sealing and the end face seal that can simultaneously be realized axial water-cooled electric machine casing by a sealing ring of this reality, optimize the processing technology of water-cooled housing, improve the cleannes of water channel, reduce housing cost and motor assembly basis, and improve the reliability of motor to a certain extent.

Fig. 3 is the structural representation of water-cooled housing；
Fig. 4 is the structural representation of end cap；
Fig. 5 is the use state diagram that this reality is novel.
Detailed description of the invention
It is described further this reality is novel below in conjunction with the accompanying drawings:
As shown in Figure 1, Figure 2, a kind of sealing ring for axial water channel motor section bar housing shown in Fig. 3, Fig. 4, Fig. 5, including pancake annular seal ring body 1, one side end face uniform intervals of sealing ring body 1 is disposed with boss 2, boss 2 seals with water channel hole 11 phase on water-cooled housing 10, the opposite side end face uniform intervals of sealing ring body 1 is disposed with the first rib 3 of annular, and first rib 3 seals mutually with seal groove 21 bottom surface of setting on end cap 20.As shown in Figure 2, it also will be understood that the cross section becoming sealing ring body 1 is in-line, the cross section being provided with the sealing ring body at boss 2 is T font, one side end face of sealing ring body 1 is provided with the equal arc boss of water channel hole 11 number, and it is semicircular seal ribs that the periphery of opposite side end face and all arc boss is provided with cross section.
Further, boss 2 is disposed with the second rib 4 along its circumference uniform intervals, and the cross sectional shape of the second rib 4 is semicircle, and the second rib seals mutually with the inwall of water channel hole 11.
Further, boss 2 entirety is that arcuation is arranged, and the shape of boss 2 matches with the shape of water channel hole 11, and the number that boss 2 is arranged matches with the number of water channel hole 11.
Further, the cross sectional shape of first rib 3 is semicircle.
The novel principle of this reality is:
This reality is novel to be arranged between section bar housing end face and the electric motor end cap with axial water channel, during assembling, arc boss portion extrusion enters in water channel hole, second rib of arc boss peripheral semi-circular tee section is deformed by the inner wall compressive of water channel hole, form the multilamellar arc consistent with water channel hole cross section around band, the recirculated cooling water stoping water-cooled housing internal water channel enters motor or leaks, so that the two ends of water-cooled housing internal water channel are sealed, form the circulation closed water channel from water inlet to outlet；In the annular one word cross section sealing groove that sealing ring body and first rib are fixed on end cap, after end cap has assembled, the end face of seal groove is fixing with the end face laminating of water-cooled housing, the bottom surface of seal groove makes the second rib by compression, form multi-layer circular around band, become to seal with external environs open form by water-cooled housing inner space, prevent external environment condition dampness moisture from entering motor, thus the water channel realizing axial water-cooled electric machine casing seals and end face seal simultaneously, when actually used, can be according to different hydraulic pressure, seal request etc., adjust first rib and the decrement of the second rib, distribution number etc., to realize preferably sealing, optimize technique, reduce cost.
Novel the having the beneficial effects that of this reality: 1) water channel of axial water-cooled electric machine casing and end face can be realized by sealing ring while seal, form multi-layer sealed band by the compression of sealing ring, reliable for effect and install simple and convenient；2) avoid traditional housing water channel welded seal and end face gluing or sealing ring seals parallel form, substantially increase the manufacturability of housing processing, improve sealing effectiveness, significantly reduce the cost of housing and motor simultaneously.
Embodiment described above is only to be described the preferred implementation that this reality is novel; not the scope that this reality is novel is defined; on the premise of without departing from this reality new design spirit; various deformation that the technical scheme that this reality is novel is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that the novel claims of this reality determine.
