Description
Technical field:
The utility model relates to the pump technology field, relates in particular to a kind of thin oil lubricant bearing part.
Background technique:
In the water pump industry; Sh, S, HS series double suction middle-opening pump are kind of products that has a large capacity and a wide range, and performance is good, and use and maintenance is convenient; Be widely used in industry and departments such as water factory, power plant, steel mill, agricultural irrigation, building, carry clear water and physicochemical properties to be similar to the liquid of clear water.Mostly double suction middle-opening pump bearing part is the rolling bearing form in the market, generally adopts grease lubrication; The most of skeleton oil seal that adopts of the sealing of bearing bore.Adopt thin oil lubricant seldom; Thin oil lubricant only just appears when using sliding bearing; But sliding bearing has high requirements to the technology that the master worker is installed, and has slightly to install unreasonablely just can not guarantee reliability of operation, may when pump operation, cause bearing heating or tile kilning; And the client will drop into great amount of manpower and goes to safeguard in daily maintenance, makes troubles to the user.
Recently, there are these two types of pumps of many customer requirements under the prerequisite of using rolling bearing, to use thin oil lubricant instead, with reliability and the reduction maintenance cost that improves pump.For this reason, some factory makes part and improves on former bearing support, and the sliding bearing lid is ball bearing, and change grease lubrication is oil lubrication, and seal form is still continued to use outside framework oil seal.After this simple modifications, there are many problems.The first cavity oil storage is limited, and radiating condition is poor, and bearing temperature rise is high.Secondly, groove type seals easy leakage of oil and contaminated; And outside framework oil seal belongs to contact seal, receives the rubber parts quality, wears out and effect of attrition, and working life is limited, often needs to change outside framework oil seal, and damages axle or axle sleeve easily, needs to change axle or axle sleeve, has increased operation expense.
The model utility content:
In order to remedy the deficiency of existing technology, the purpose of the utility model provides a kind of thin oil lubricant bearing part, and bearing seal performance and heat dispersion are greatly improved.
The technological scheme of the utility model is following:
The thin oil lubricant bearing part, bearing support, main shaft, main shaft passes bearing support; Between bearing support inwall left end and the main shaft bearing is installed, described bearing support left end has the bearing gland that is set in outside the main shaft, and bearing gland withstands bearing; It is characterized in that: have left seal to be set between main shaft and the bearing gland, be fixed with dustproof dish on the main shaft outside left seal and the bearing gland, described bearing support outer wall is provided with integrated radiating fin; Be provided with the grease chamber in the bearing support, the both sides that grease chamber's inwall is relative are provided with input oil groove, are combined with the locking nut that withstands described bearing on the main shaft of grease chamber's left end; Be fixed with disc on the main shaft at middle part, grease chamber; Be combined with right seal between grease chamber's right-hand member and the main shaft, the fan of synchronous rotation is installed on the main shaft in the outside of grease chamber, the bearing support right-hand member is fixed with fan guard.
Described thin oil lubricant bearing part is characterized in that: the sidewall that described left seal, right seal and main shaft are fitted is provided with thread groove.
Described thin oil lubricant bearing part is characterized in that: described bearing support outer wall upper and lower sides is provided with vent, the spill port with grease chamber UNICOM, is separately installed with air plug, purge cock in vent and the spill port.
The utility model has the advantages that:
The spiral seal that the utility model adopts is effective, has solved the sealing problem of bearing part, and the structural design of bearing support cooperates the use of fan, makes radiating condition good, has prolonged the working life of bearing part.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the bearing block structure schematic representation of the utility model.
Embodiment:
Referring to Fig. 1, Fig. 2:
The thin oil lubricant bearing part, bearing support 1, main shaft 2, main shaft 2 passes bearing support 1; Between bearing support 1 inwall left end and the main shaft 2 bearing 3 is installed, bearing support 1 left end has the bearing gland 4 that is set in outside the main shaft 2, and bearing presses 4 caping to live bearing 3; There is left seal 5 to be set between main shaft 2 and the bearing gland 4, is fixed with dustproof dish 6, the entering bearing bores (grease chamber) such as liquid that stop extraneous dust impurity and main shaft seal place to leak out on the main shaft 2 outside left seal 5 and the bearing gland 4; Bearing support 1 outer wall is provided with integrated radiating fin 7; Be provided with grease chamber 8 in the bearing support 1, the relative both sides of 8 inwalls, grease chamber are provided with input oil groove 9, are combined with the locking nut 10 that withstands bearing 3 on the main shaft 2 of grease chamber's 8 left ends; Be fixed with disc 11 on the main shaft 2 at 8 middle parts, grease chamber; Be combined with right seal 12 between grease chamber's 8 right-hand members and the main shaft 2, the fan 13 of synchronous rotation is installed on the main shaft 2 in the outside of grease chamber 8, bearing support 1 right-hand member is fixed with fan guard 14.
Left side seal 5, right seal 12 are provided with thread groove 15 with the sidewall that main shaft is fitted, and the pumping effect of thread groove is failed in the spill port lubricant oil of desiring toward external leakage again, plays seal action.
The utility model mainly is used in horizontal two end supports or the used bearing part of intermediate support class pump.When design, taken into full account the lubricated and cooling problem of bearing; Design provides the input oil groove of bearing cooling and lubricating fluid in bearing support; Through disc 11 lubricating oil splash is arrived in the input oil groove 9; Let low temperature oil sources source constantly get into bearing, the heat that produces when taking away the bearing operation, the high temperature oil of taking away heat gets into the radiating fin 7 and fan 13 coolings of grease chamber 8 through bearing support 1 surface from the spill port circulation.It is big or very good with effect when pumping high-temp liquid that bearing support 1 is worn power ratio at pump, and therefore, the utility model bearing part can be widely used in opening in the horizontal double suction centrifugal pump, horizontal multi-stage centrifugal pump etc.
