The utility model provides a spiral baffle type gearbox exhaust pipe, which comprises a pipe body, wherein the pipe body is provided with a pipe cavity which is communicated from top to bottom; the method is characterized in that: the spiral separation blade is arranged in the pipe cavity of the pipe body and comprises a central shaft and spiral blades, and the spiral blades are spirally distributed along the central shaft; the spiral blades are attached to the inner wall of the pipe body.
The upper end of the pipe cavity of the pipe body is provided with an oil mist filter element.
Install two fixed bolsters in foretell body, divide into upper and lower fixed bolster, and the fixed bolster includes outer fixed ring, interior fixed ring and connecting rod, and outer fixed ring and interior fixed ring arrange with the axle center, connect through the connecting rod between the two.
The spiral retaining sheet is installed between the upper fixing support and the lower fixing support, a central shaft of the spiral retaining sheet is a stepped shaft, the upper end of the central shaft is inserted into a central hole of an inner fixing ring of the upper fixing support, an upper end shaft shoulder is propped against the inner fixing ring, the lower end of the upper end shaft shoulder is inserted into the central hole of the inner fixing ring of the lower fixing support, and a lower end shaft shoulder is propped against the inner fixing ring.
Foretell last fixed bolster's outer fixed ring and body inner wall fixed connection, the inner wall of body lower extreme is equipped with the internal thread, is equipped with the external screw thread on the outer wall of the outer fixed ring of lower fixed bolster, the outer fixed ring of lower fixed bolster and the cooperation of body lower extreme inner wall screw thread.
The outer wall of the upper end of the pipe body is provided with external threads, and the upper end of the pipe body is in threaded fit with the dustproof cover.
Compared with the prior art, the utility model discloses following outstanding beneficial effect has:
1. the utility model combines the advantages of the ventilating cap and the ventilating pipe, the spiral separation blade blocks oil drops, thereby avoiding splashing and improving the splashing height;
2. compare in the design that the ventilation tube enlarged the latus rectum and realized buffering atmospheric pressure, the utility model discloses, realize buffering atmospheric pressure with the spiral separation blade, the volume is littleer, and is littleer to installation space's requirement, and the suitability is wider.
Drawings
Fig. 1 is a schematic diagram of the internal structure of the present invention.
Fig. 2 is a schematic structural view of the fixing bracket of the present invention.
Detailed Description
The invention is further described with reference to the drawings and the detailed description.
