Detailed description of the invention

Refer to accompanying drawing 1 to Fig. 5, this utility model is a kind of electromotor 100, and it includes the casing 10 with respiratory chamber 103, the pressing plate 20 being installed on respiratory chamber 103, elastic component 30, sealing gasket 40 and breathes lid 50.

As shown in Figures 2 to 5, casing 10 forms for metal material die casting, it includes matrix 101 and being enclosed by matrix 101 and sets the working chamber 102 forming and working for the bent axle (not shown) of electromotor, by matrix 101 interval between working chamber 102 and respiratory chamber 103, working chamber 102 is positioned at the inner surface of matrix 101, and respiratory chamber 103 is positioned at the outer surface of matrix 101.

Respiratory chamber 103 includes the breathing wall 1031 outwardly extended from matrix 101, and breathing wall 1031 be closed, outwardly extends to form flange 10361 from matrix 101, and flange 10361 is positioned at breathes wall 1031.Breathing wall 1031 is enclosed the region segmentation set and becomes respiratory region 1032 and labyrinth district 1037 by flange 10361.The surface of breathing wall 1031, flange 10361 and matrix 101 is enclosed and is set formation respiratory region 1032.The first installing hole 10311 is formed to matrix 101 direction depression from the surface breathing wall 1031.Upwardly extend the pressure release wall 1033 forming closed from the bottom surface of respiratory region 1032, pressure release wall 1033 encloses and sets formation relief hole 1034, and relief hole 1034 is through with working chamber 102.Formation one mounting post 1035 is upwardly extended from the bottom surface of respiratory region 1032, self installation post 1035 concave downward forms the second installing hole 10351, in the present embodiment, a segment distance is formed between mounting post 1035 and pressure release wall 1033, the surface of mounting post 1035 flushes with the surface of pressure release wall 1033, pressing plate 20 is installed in mounting post 1035 by pressing plate installed part 21, and installed part 21 is fixed in the second installing hole 10351.Flange 10361 jointly encloses with breathing wall 1031 and sets formation labyrinth district 1037.In other embodiments, labyrinth district 1037 can also be that flange 10361 encloses to set and forms.Extending obliquely out formation the second rib the 10362, the 3rd rib the 10363, the 4th rib 10364 from flange 10361, the second rib the 10362, the 3rd rib 10363 and the 4th rib 10364 all extend to labyrinth district 1037 from flange 10361, and both are at a distance.Extending to form the 5th rib 10365 and the 6th rib 10366 from breathing wall 1031 in labyrinth district 1037, the 3rd rib 10363 is between the 4th rib 10364 and the 5th rib 10365.5th rib is between the second rib 10362 and the 3rd rib 10363, and the 6th rib 10366 is between the 3rd rib 10363 and the 4th rib 10364.The rib extended to direction, labyrinth district 1037 from flange 10361 and the rib extended to direction, labyrinth district 1037 from breathing wall 1031 interlock and form, and the rib between staggered forms some ports 10371.Labyrinth district 1037 is isolated into some labyrinth chamber 10372 by some ribs, and some labyrinth chamber 10372 are mutually communicated by port 10371.Such port 10371 not on the same line, adjacent port 10371 towards not in same direction.When the liquid in labyrinth district 1037 flows, by some rib intervals, it is possible to hinder the flowing velocity of liquid.Flange 10361 has the breach 1038 running through respiratory region 1032 with labyrinth district 1037.

In conjunction with, shown in Fig. 2 to Fig. 5, forming a spill port 10373 from the bottom surface concave downward of a labyrinth chamber 10372 of one end, labyrinth district 1037, this labyrinth chamber 10372 is connected by spill port 10373 and working chamber 102.From a labyrinth chamber 10372 of labyrinth district 1037 other end, there is a passage 10374, this passage 10374 is formed from labyrinth chamber 10372 concave downward, this passage 10374 is not limited to be formed from labyrinth chamber 10372 concave downward, and in other embodiments, this passage 10374 is through with the external world.In the present embodiment, a through passage 10374 of through hole 10375 is with extraneous, and this through hole 10375 bearing of trend is paralleled with the surface in labyrinth district 1037, and is mutually perpendicular to passage 10374.The internal diameter of through hole 10375 is more than the internal diameter of passage 10374.By through hole 10375 with passage 10374, it is ensured that outside air communicates with respiratory region 1032 with labyrinth district 1037.By passage and through hole and described outside air to through, by the internal diameter of the through hole internal diameter more than passage, both ensured that the size of passage met the demand of electromotor, not blocked.Respiratory chamber is designed to maze-type structure, it is possible to effectively reduce the spray volume of machine oil in respiratory chamber.

During installation, pressing plate 20 is installed in mounting post 1035 by pressing plate installed part 21, compresses elastic component 30 above pressing plate 20, and seal washer 40 is placed and the surface breathing wall 1031, by bolt 51, breathing is covered 50 and is installed on respiratory chamber 103.Bolt 51 is fixed in the first installing hole 10311.

As it is shown in figure 5, the bottom surface in labyrinth district 1037 is not with to breathe wall 1031, flange 10361 perpendicular.Labyrinth district 1037 bottom design becomes the structure tilted to spill port 10373 direction, that is, it is positioned at other positions lower than labyrinth district 1037, the position in labyrinth district of spill port place 1037, is conducive to the machine oil accumulating in labyrinth district 1037 to be back to smoothly in working chamber 102.

Arranged by some ribs in labyrinth district 1037 and port 10371, it is possible to effectively reduce engine housing 10 and enclose the spray volume of machine oil in the working chamber 102 set.

When in working chamber 102, pressure is excessive, the machine oil in working chamber 102 can be discharged in respiratory region 1032 from relief hole 1034.At working chamber 102 one pressing plate 20 of relief hole 1034 Position Design, and on pressing plate 20, place an elastic component 30, it is possible to effectively slow down the spray volume of working chamber 102 inner engine oil.

Schematically this utility model and embodiment thereof being described above, this description does not have restricted, and shown in accompanying drawing is also one of embodiment of the present utility model, and actual structure is not limited thereto.So, if those of ordinary skill in the art is enlightened by it, when creating objective without departing from this utility model, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
