Abstract
A device for automatically lubricating a vertical pump bearing by utilizing two holes relates to pumps. A bearing 10 is arranged in a bearing block 3, an inner ring of the bearing 10 is sheathed on a bearing body 9 which is fixed on a shaft 8 by a key, an inclined oil hole 4 is drilled in an axial tangent plane on the bearing body 9, then a radial oil hole 6 is drilled in the axial tangent plane, the inclined oil hole 4 and the radial hole 6 are crossed, and can not be drilled through, an included angle formed by the central lines of the inclined oil hole 4 and a shaft is more than 2 degrees, and the bearing body 9 is dipped in oil by more than 15mm, but can not be dipped to the bearing. Oil ascends to an upper oil storing cavity under the action of the centrifugal force so as to achieve the bearing lubricating effect. The device is simple in operation and only can be drilled with two holes.
Description
Technical field
The utility model relates to a kind of oilless bearing device of vertical pump, is a kind of automatic up lubricating bearings of thin oil that makes, and improves the device of bearing life.
Background technique
We know, the lubricating fitting of existing vertical type pump bearing is in bearing support, to be provided with bearing, and bearing outer ring is in bearing gland is fixed on bearing support; Bearing inner sleeve is fixed on the axle through bearing support, and the bearing below is provided with shoe cream room, because shoe cream room is below bearing; Oil in the lubricant reservoir is difficult for up, and the lubricant oil that gets into bearing also flows into lubricant reservoir, fuel feeding weak effect very soon; The lost of life of bearing, operational reliability is low, the lost of life of pump.
Summary of the invention
The technical problem that the present invention solves is: solution bearing oil is difficult for up, and the oil that gets into bearing flows into lubricant reservoir again very soon, the fuel feeding weak effect, and the characteristics of operational reliability provide oily up lubricating fitting automatically in a kind of lubricant reservoir.
The technological scheme that the utility model adopted is: formed time shoe cream room by separation sleeve and bearing support, come storing lubricating oil.On bearing support, bored an inclined oil hole of air, and then bored a radial direction oil hole and communicate with the inclined oil hole of air that bore the front, inclined oil hole of air is crossed in the oil immersion of following shoe cream room, and oil is in action of centrifugal force, up come out, and shoe cream room in the arrival reaches the purpose of oilless bearing.
The beneficial effect of the utility model is: make bearing obtain good lubricating, prolonged the working life of bearing, thereby prolonged the working life of pump.
Description of drawings
Accompanying drawing: the section of structure of lubricating fitting.
Description of drawings: 1. separation sleeve, 2. descend shoe cream room, 3. bearing support, 4. inclined oil hole of air is 5. gone up shoe cream room, 6. radial direction oil hole, 7. adjustment nut, 8. spool, 9. bearing support, 10. bearing, 11. bearing glands.
Embodiment:
A kind of oilless bearing device of vertical pump as shown in the figure in the bearing support 3, is provided with bearing 10, and bearing 10 inner rings are enclosed within on the bearing support 9; Bearing support 9 is fixed on the axle 8 through strong, in the tangent plane on bearing support 9, is drilled with an inclined oil hole of air 4; And then being drilled with a radial direction oil hole 6, inclined oil hole of air 4 intersects with radial hole 6, and two holes all can not drill through; The angle of inclined oil hole of air 4 center lines and shaft centre line is greater than 2 degree, and bearing support 9 immerses the degree of depth in the oil greater than 15mm, but can not be dipped into bearing.When axle rotated, bearing support and then changeed, and under action of centrifugal force, the oil in the following shoe cream room 2 arrives radial hole 6 on inclined oil hole of air 4, under action of centrifugal force, be thrown to shoe cream room 5, thereby reach the purpose of oilless bearing.
