Abstract
The utility model discloses an oil leakage resistant structure for a fan transmission group and relates to an improved oil leakage resistant structure for the fan transmission group. The oil leakage resistant structure for the fan transmission group has a good oil leakage resistant effect, and comprises a transmission group spindle, wherein two sides of the transmission group spindle are provided with bearing boxes; the ends of the bearing boxes are connected with bearing covers; oil slingers are arranged in the bearing covers and are arranged on the transmission group spindle; oil seals are arranged at the ends of the bearing covers; and the oil leakage resistant structure is characterized in that oil return holes are formed at the bottoms of the oil seals.
Description
Technical field
the utility model relates to the improvement of blower fan transmission group leak-proof arrangement.
Background technique
In
existing blower fan transmission group leak-proof arrangement, oil sealing 103 bottoms do not have spill port, after asbestos packing 102 is passed through in the oil immersion that disc 104 spills, can extrude from bearing cap 101, so the blower fan transmission group in use are prone to take place oil leakage phenomenon.
Summary of the invention
the utility model is exactly to the problems referred to above, provides a kind of anti-leakage of oil effective blower fan transmission group leak-proof arrangement.
are for realizing above-mentioned purpose; The utility model adopts following technological scheme; The utility model comprises the transmission group main shaft, and transmission group main shaft both sides are provided with bearing housing, and the bearing housing end is connected with bearing cap; Be provided with disc in the bearing cap, disc is installed on the transmission group main shaft; The bearing cap end is provided with oil sealing, and its structure outline oil sealing bottom is provided with spill port.
are lined with first asbestos washer as a kind of preferred version between said oil sealing of the utility model and the bearing cap end.
as another kind of preferred version, the said oil sealing of the utility model is an integral structure, and adopts HT150 gray cast iron oil sealing.
are lined with second asbestos washer as another kind of preferred version between said bearing cap of the utility model and the bearing housing end.
as another kind of preferred version, the thickness of said second asbestos washer of the utility model is 2mm.
are interference fit between said disc of the utility model and the transmission group main shaft secondly.
in addition, the gap of said disc of the utility model and oil sealing is 2mm.
the utility model beneficial effect: the utility model oil sealing bottom is provided with spill port; Oil from disc spills can flow back in bearing cap and the bearing housing along spill port, effectively prevents leakage of oil.
Description of drawings
further specify the utility model below in conjunction with accompanying drawing and embodiment.The utility model protection domain not only is confined to the statement of following content.
Fig. 1 is the utility model structural representation.
Fig. 2 is existing blower fan transmission group leak-proof arrangement schematic representation.
Embodiment
are as shown in the figure, and the utility model comprises transmission group main shaft 8, and transmission group main shaft 8 both sides are provided with bearing housing 6, and bearing housing 6 ends are connected with bearing cap 1, are provided with disc 5 in the bearing cap 1, and disc 5 is installed on the transmission group main shaft 8; Bearing cap 1 end is provided with oil sealing 2, and oil sealing 2 bottoms are provided with spill port 4.
Be lined with first asbestos washer 3 between
said oil sealing 2 and bearing cap 1 end; Increase tightness.
said oil sealing 2 is an integral structure, and adopts HT150 gray cast iron oil sealing.HT150 gray cast iron belongs to middle intensity ironcasting, and good casting property, technology is simple, casting stress is little, can be without artificial aging.
Be lined with second asbestos washer 7 between
said bearing cap 1 and bearing housing 6 ends; Increase tightness.
The thickness of
said second asbestos washer 7 is 2mm.
Between
said disc 5 and the transmission group main shaft 8 is interference fit.
said disc 5 is 2mm with the gap of oil sealing 2.
are below in conjunction with the installation process of description of drawings the utility model: during assembling, heating disc 5 earlier, with oil sealing 2 with disc 5 propelling transmission group main shafts 8 after, pull down oil sealing 2, load onto first asbestos washer 3, install oil sealing 2 again.
it is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technological scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
