Abstract
The utility model discloses a device utilizing an oil groove to automatically lubricate a vertical pump bearing, which relates to the pump type. A bearing (11) is arranged in a bearing seat (3); an inner ring of the bearing (11) is sleeved on a bearing body (9); the bearing body (9) is fixed to a shaft (8) by a key; an oil groove (5) is milled on the bearing body (9) and a radial oil hole is drilled on the bearing body (9) as well; the oil groove is communicated with the radial oil hole; the bearing (11), a locknut (12) and the bearing body (9) form one oil groove together; and the oil level of a lower oil storing chamber (2) is more than 15 mm higher than the radial oil hole (4) but does not dip the bearing (11). The cylindrical surfaces of the bearing body (9) and the locknut (12) adopt clearance fit with each other; the oil moves up to an upper oil storing chamber (10) by the effect of the centrifugal force, thereby implementing an effect of lubricating the bearing; the device utilizing oil groove to automatically lubricate the vertical pump bearing is simple to operate and capable of machining the oil groove (5) and the radial oil hole (4) on a miller without replacing the cutter and moving the clamp.
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 difference provide a kind of device that makes lubricant oil automatic up lubricating bearings in the chamber.
The technological scheme that the utility model adopted is: formed time shoe cream room by separation sleeve and bearing support, come storing lubricating oil, be provided with bearing in the bearing support; Bearing inner race is fixed on the bearing support, on bearing support, has bored a radial direction oil hole, and then mills an oil groove that several mm are wide; Form an oil groove hole jointly by bearing support, bearing and locking nut; Spielpassung is adopted in the cylndrical surface of cylndrical surface, bearing support lower end and locking nut, and the pasta of following shoe cream room surpasses more than the radial direction oil hole 15mm, but is not dipped into bearing; Oil is up to shoe cream room along oil groove under action of centrifugal force, reach 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, processing oil groove and radial direction oil hole are also very convenient, are placed on the milling machine disposablely to process.

Accompanying drawing 2: bearing support outline drawing.
Description of drawings: 1. separation sleeve, 2. descend shoe cream room, 3. bearing support, 4. radial direction oil hole, 5. oil groove, 6. bearing gland, 7. adjustment nut, 8. spool, 9. bearing support is 10. gone up shoe cream room, 11. bearings, 12. locking nuts.
Embodiment:
A kind of oilless bearing device of vertical pump as shown in the figure in the bearing support (3), is provided with bearing (11); Bearing (11) inner ring is enclosed within on the bearing support (9), and bearing support (9) is fixed on the axle (8) through key, goes up at bearing support (9) and has milled a radial direction oil hole (4) with milling machine; And then mill an oil groove (5), and radial direction oil hole (4) and oil groove (5) communicate, and bearing support (9), locking nut (12), bearing (11) etc. have been formed an oil groove hole jointly; The pasta of following shoe cream room (2) surpasses radial direction oil hole (4) more than the 15mm, but is not dipped into bearing (11), when axle (8) rotates; Bearing support (9) and then changes, and under action of centrifugal force, the oil in the following shoe cream room (2) is through under the effect of radial direction oil hole (4); Produce pressure; A little lubricant oil outside reveal in the gap of bearing support (9) and locking nut (12), most of oil shoe cream room (10) in oil groove (5) arrival, thus reach the purpose of oilless bearing.
Claims (1)
1. device that utilizes oil groove self oiling vertical type pump bearing; It is characterized in that: be provided with bearing (11) in the bearing support (3); Bearing (11) inner ring is fixed on the bearing support (9); On bearing support (9), bored a radial direction oil hole (4) and milled an oil groove (5), formed an oil groove hole jointly by bearing support (9), bearing (11) and locking nut (12), Spielpassung is adopted in the cylndrical surface of bearing support (9) cylndrical surface, lower end and locking nut (12); The pasta of following shoe cream room (2) surpasses radial direction oil hole (4) more than the 15mm; But be not dipped into bearing (11), oil is up to shoe cream room (10) along oil groove under action of centrifugal force, thereby lubricating bearings.
