Detailed description of the invention

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

As shown in Figures 2 to 5, casing 10 forms for metal material die casting, it includes that matrix 101 and being enclosed by matrix 101 sets the working chamber 102 forming and working for the bent axle (not shown) of electromotor, it is spaced by matrix 101 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 is closed, forms the first rib 10361 from the outwardly extension of matrix 101, and the first rib 10361 is positioned at breathing wall 1031.Breathing wall 1031 is enclosed the region segmentation set and becomes respiratory region 1032 and labyrinth district 1037 by the first rib 10361.The surface of breathing wall the 1031, first rib 10361 and matrix 101 is enclosed and is set formation respiratory region 1032.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 pressure-releasing chamber 1034, and pressure-releasing chamber 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.First rib 10361 jointly encloses with breathing wall 1031 and sets formation labyrinth district 1037.In other embodiments, labyrinth district 1037 can also be that the first rib 10361 encloses to set and forms.Formation the second rib the 10362, the 3rd rib the 10363, the 4th rib 10364 is extended obliquely out from the first rib 10361, second rib the 10362, the 3rd rib 10363 all extends to labyrinth district 1037 from the first rib 10361 with the 4th rib 10364, and both are at a distance.Extending formation the 5th rib 10365 and the 6th rib 10366 in labyrinth district 1037 from breathing wall 1031, the 3rd rib 10363 is between the 6th rib 10366 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 the first rib 10361 is staggered with the rib extended to direction, labyrinth district 1037 from breathing wall 1031 to be formed, and the rib between interlocking 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 the most on the same line, adjacent port 10371 towards not in same direction.When the liquid in labyrinth district 1037 flows, it is spaced by some ribs, the flowing velocity of liquid can be hindered.There is on first rib 10361 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 with working chamber 102 by spill port 10373.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 of through hole 10,375 10374 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 and passage 10374, it is ensured that outside air communicates with respiratory region 1032 with labyrinth district 1037.Respiratory chamber is designed to maze-type structure, can effectively reduce the spray volume of machine oil in working area.

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, is installed on respiratory chamber 103 by breathing lid 50 by bolt 51.Bolt 51 is fixed in the first installing hole 10311.

The bottom surface in labyrinth district 1037 is not perpendicular with breathing wall the 1031, first rib 10361.Labyrinth district 1037 bottom design becomes the structure tilted to spill port 10373 direction, that is, the position being positioned at the labyrinth chamber 10372 at spill port 10373 is less than the labyrinth chamber 10372 of other positions, is conducive to accumulating in the machine oil in labyrinth district 1037 and is back to smoothly in working chamber 102.

Some ribs and port 10371 by labyrinth district 1037 are arranged, and can effectively reduce the spray volume of middle machine oil in engine housing 10 encloses 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 pressure-releasing chamber 1034.At working chamber 102 one pressing plate 20 of pressure-releasing chamber 1034 Position Design, and on pressing plate 20, place an elastic component 30, can effectively slow down the spray volume of working chamber 102 inner engine oil.

Schematically being described this utility model and embodiment thereof above, this description does not has 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, in the case of creating objective without departing from this utility model, design the frame mode similar to this technical scheme and embodiment without creative, protection domain of the present utility model all should be belonged to.
