Abstract
The present invention discloses a lubricating oil pressure suspension bearing bush. It is formed from pressure-bearing bush and cover bush. It is characterized by that in the middle portion of inner wall of said pressure-bearing bush are set several oil-charging channels which are uniformly and symmetrically distributed, and in the most outside end of inner wall of said pressure-bearing bush a circular recovering channel is set, said circular recovering channel is used for enclosing said oil-charging channels and is not communicated with said oil-charging channels, in the most outside end of inner wall of said cover bush also a circular recovering channel is set, said circular recovering channel is communicated with the circular recovering channel of pressure-bearing brush, the oil inlet pipe, pressure oil pump and recovering pipe are formed into a circulation system. Said invention can make long-term lubrication between inner wall of bearing bush and bearing, and is applicable to train and power generator, etc.
Description
Technical field
The present invention relates to bearing liner, especially relate to a kind of lubricating oil pressure suspension bearing bush.
Technical background
Bearing liner is avoided damage of bearings because of bearing bigger pressure, uses comparatively general among stressed big train, generator.Between bearing liner and bearing, often smear butter to solve lubrication problem between the two, but because the inwall of the bearing liner of pressure-bearing has huge frictional force when bearing great pressure mutually, the butter of lubricate can be consumed very soon, the inwall of bearing liner and the frictional force between the bearing are increased gradually, resistance increases, thereby influences the rotation of bearing, has reduced the generating efficiency of train speed or generator, and be rapidly heated, damage bearing liner; Even more serious is, as untimely additional butter, will locking between the inwall of bearing liner and the bearing, and produce serious accident.
Summary of the invention
The purpose of this invention is to provide a kind of can be in state of suspension, high lubricating effect between the inwall that lubricates, make bearing liner between the inwall of bearing liner and the bearing for a long time and the bearing, reduce friction, prolong the working life, energy saving of bearing liner, lubricating oil pressure suspension bearing bush simple in structure.
The object of the present invention is achieved like this: the present invention is made up of pressure-bearing watt and cover tile, feature is the oil-filled groove of sealing around the inwall middle part of pressure-bearing watt is processed with, oil inlet hole passes pressure-bearing watt wall and communicates with oil-filled groove, inwall outermost end in pressure-bearing watt is processed with an annular accumulator tank that surrounds oil-filled groove and do not communicate with oil-filled groove, oil outlet passes pressure-bearing watt wall and communicates with accumulator tank, the oil outlet end of the oil-feed termination pressure oil pump of oil inlet pipe, the oil outlet end of oil inlet pipe taps into the oil inlet end of oilhole, the oil inlet end of recovery tube picks out the oil outlet end of oilhole, the oil inlet end of the fuel-displaced termination pressure oil pump of recovery tube; Be processed with an annular accumulator tank that communicates with the annular accumulator tank of pressure-bearing watt in the inwall outermost end of cover tile.
Inwall middle part in pressure-bearing watt is processed with two or more evenly spaced oil-filled grooves, adjacent two oil-filled grooves are communicated with by open channel or hidden pipe, the direction of the oil-filled groove of Fen Buing is vertical with bearing axis symmetrically, and oil inlet hole passes pressure-bearing watt wall and communicates with middle oil-filled groove.
The width of accumulator tank and the degree of depth are greater than the width and the degree of depth of oil-filled groove.
The present invention adopts pressure oil pump that lubricant oil is pressed in the bearing liner from oil inlet hole by oil inlet pipe, by the oil-filled groove of arranging symmetrically and evenly lubricant oil is overflowed then, lubricated for a long time to carrying out between the inwall of bearing liner and the bearing, and produce the oil film as thin as a wafer of a huge holder power, make between the inwall of bearing and bearing liner and be in state of suspension, can directly not contact, allow the bearing can long-time steady running.The oil of seepage is regained the oil that overflows by accumulator tank when bearing and bearing liner operation, sends pressure oil pump back to through recovery tube and recycles.Sealing can guarantee to produce high pressure around the oil-filled groove,, distribute symmetrically and can guarantee lubricating oil pressure symmetrically, make shaft strength even.The direction of oil-filled groove can reduce friction perpendicular to bearing axis, makes shaft strength even.The width of accumulator tank and the degree of depth be greater than the width and the degree of depth of oil-filled groove, and be in low-pressure state, so can prevent that lubricant oil is excessive.The present invention can also monitor pressure, oil pressure buoyancy between the inwall of oil temperature, bearing and bearing liner automatically by monitoring equipment, to reach automatic adjusting oil temperature, pressure and oil pressure buoyancy, makes bearing be in best state of suspension all the time.Train Shang watt be pressure-bearing watt, following watt is cover tile, and following watt of generator is pressure-bearing watt, Shang watt be cover tile.With the train is example, as pressure-bearing watt heating, illustrates that then oil pressure is not enough, does not suspend, and friction is big, need increase oil pressure; As the cover tile heating, illustrate that then oil pressure is excessive, need subtract oil pressure.The desirable suspension, and frictional force minimum to pressure-bearing watt and cover tile all do not have high heat.Therefore the present invention has and can working life, energy saving, the advantage of simple structure that be in state of suspension, high lubricating effect, reduces friction, prolongs bearing liner between the inwall that lubricate, make bearing liner between the inwall of bearing liner and the bearing for a long time and the bearing be suitable for using in train, generator and the automobile.
