Abstract
The utility model relates to the improvement on the oil leakage of a bearing seat, in order to achieve the aim of oil tightness by improving side covers at the two ends of the bearing seat. An blower bearing seat without oil leakage comprises a bearing seat body, wherein two to three trapezoidal oil tanks are arranged on the wall of the side cover of the bearing seat body; oil-impregnated industrial felts are embedded in the oil tanks; and a skeleton oil chamber is arranged outside the side cover and is internally provided with a skeleton oil seal which is pressed by a small oil cap, so that the aim of oil sealing is achieved by twice oil sealing. In case of oil leakage, only the oil seal needs to be replaced; so that the repair is convenient and the loss is reduced.
Description
Technical field
The utility model belongs to fan manufacturing technology field.
Background technique
Bearing support is the pith of blower fan, and the bearing support leakage of oil is concerning that can blower fan run well, and many producers all can't estimate because of the loss that the bearing support leakage of oil causes.
Side cover originally is 2-3 trapezoidal oil groove (as shown in Figure 1) of processing on the side cover wall, oil groove is embedded in the industrial felt with oil immersion, utilize felt oil suction principle to reach the control leakage of oil, the meeting of long duration that felt is used is aging, axle can produce heat when rotating also can lose felt, like this must the first quarter or change felt one time half a year, change felt at every turn and just equal to repair bearing support one time, will cause damage for like this applying unit.
Summary of the invention
The utility model purpose is to improve the side cover sealing configuration at bearing support two ends, stops leakage of oil.
Specifically, oil tight bearing fan, has the bearing support body, 2-3 trapezoidal oil groove of processing on the side cover wall of bearing support body side cover, oil groove is embedded in the industrial felt with oil immersion, install a skeleton grease chamber and skeleton grease chamber the inside dress outside framework oil seal in the outside of side cover additional, outside framework oil seal is compressed with small oil cover.
The utility model installs a skeleton grease chamber additional in the side cover outside, and the inside dress outside framework oil seal compresses outside framework oil seal with small oil cover, carries out the purpose that the secondary oil sealing reaches oil sealing like this.Even leakage of oil occurs, only need to change oil sealing, it is also convenient to repair, and has reduced loss.
