Abstract
The utility model discloses a bearing housing oil return device for a vertical pump. The oil return device comprises a bearing body and a shaft neck, wherein the bearing body and the shaft neck are sequentially sheathed on a shaft, an angular contact ball bearing is arranged on the lower part of the bearing body, a deep groove ball bearing is arranged on the outside of the shaft neck, a bearing bracket is arranged on the outside of the deep groove ball bearing, a bearing body cap is arranged on the upper part of the bearing bracket, the upper part of the bearing body cap is sequentially provided with an oil return cap and an adjusting nut, the upper part of the bearing body cap and the lower part of the oil return cap are respectively provided with a spigot, and the spigots are oppositely arranged. When a bearing rotates, the oil of an oil pool in a bearing housing flows upwards along the shaft neck to the area below the oil cap under the action of centrifugal force, and once the oil enters a labyrinth section formed by the spigot of the bearing body cap and the spigot of the oil return cap, the oil returns to the oil pool along the original path under the action of gravity.
Description
Technical field
The utility model relates to a kind of oil return apparatus, is specifically related to a kind of vertical pump bearing housing oil return apparatus that can effectively prevent seepage.
Background technique
Existing vertical pump adopts rubber seal to seal with the seal arrangement of bearing housing middle (center) bearing, the reason of and spin friction aging because of the time, and the sealing of rubber seal can be lost efficacy, and the centrifugal force of axle rotation generation makes oil seepage.Because the seepage of oil, need to ceaselessly refuel and cause waste, if refuel untimelyly, bearing can lose efficacy because of dry combustion method and cause shutting down.Therefore, adopt vertical pump that rubber seal seals to have many drawbacks such as lack of lubrication, working life be short with the bearing housing bearing.
Summary of the invention
The purpose of this utility model is that to overcome prior art not enough and a kind of seepage that can effectively prevent is provided, and simple in structure, the vertical pump of long service life bearing housing oil return apparatus.
The purpose of this utility model is achieved in that a kind of vertical pump bearing housing oil return apparatus, comprise axle, bearing support, axle journal, angular contact ball bearing, deep groove ball bearing, bearing bracket stand, the bearing support lid, bearing support and axle journal are enclosed within on the axle successively, angular contact ball bearing is arranged on the bottom of bearing support, deep groove ball bearing is arranged on the bottom in the axle journal outside, bearing bracket stand is arranged on the outside of deep groove ball bearing, the top of bearing support, the bearing support lid is arranged on the outside of axle journal, the top of bearing bracket stand, it is characterized in that: be provided with the oil return lid on the top of bearing support lid, the bottom of the top of bearing support lid and oil return lid is provided with seam, bearing support lid seam and oil return lid seam are oppositely arranged, and the top of oil return lid is provided with adjusting nut.
The degree of depth of described oil return lid seam 8b is 0.15-0.2D.D is the diameter of axle 1 in the formula.
Compared with prior art, the utility model has the advantages that:
1, the utility model has thoroughly solved vertical type pump bearing case Leakage by the labyrinth oil-returning structure that bearing support lid seam and oil return lid seam form.When bearing rotary, because of the effect of centrifugal force, the oil of oil sump upwards arrives the below of oil return lid in the bearing housing along axle journal, in case enter into the labyrinth section that is combined into by bearing support lid seam and oil return lid seam, because of action of gravitation, oil turns back to oil sump from former road.
2, compare with existing seal with elastometic washer mode, the utility model has only increased the cost of oil return lid and adjusting nut, but has reduced the cost of shutdown maintenance replacing rubber ring, and latter's cost is higher than the former greatly, and simple in structure, long service life.
