Abstract
The utility model relates to a front end oil feeding air compressor having duplex bearing with sealing structure, in particular to front end gland type oil inlet air compressor having duplex bearing. The utility model comprises a crankcase, a flange, a cylinder cover assembly, a cylinder body, a fore bearing, a back bearing, a crankshaft, and a piston arranged in cylinder body motions alternately driven by the crankshaft. The input shaft of the front end of the compressor crankshaft is communicated with the gear box of the engine, the back end of the crankshaft is communicated with the high pressure oil pump, the fore bearing and the back bearing are the bear of the load, which is characterized in that: the front bearing of the input shaft at the front end of the compressor crankshaft is an airtight structure to feed the oil at the sealing part that bears no load and only has the assistant function of sealing the lubricating oli. The utility model has the advantages of guaranteeing the compressor is not larger than the amount of rated return oil and the oi stored l in the crankcase is very small, effectively dealing with oil channeling of the compressor and oil leakage of the tail end, having a simple structure, enhancing the reliability and environmental protection of the compressor used by the diesel engineand having a good assembling and processing technique.
Description
Technical field:
The utility model relates to a kind of front end oil-feed air compressor of duplex bearing band sealing configuration, particularly duplex bearing forward end seal axle sleeve type oil-feed air compressor.
Background technique:
Known air compressor arrangement such as Fig. 1, Fig. 2, shown in Figure 3 are by crankcase 3, cylinder cap assembly 11, cylinder body 12, oil sealing 4, rear bearing 5, bent axle 6, flange 7, fore bearing 9 with place in the cylinder body and to drive pistons reciprocating 1 by bent axle 6, connecting rod 2 and constitute.The input shaft of the front end of air compressor crank is connected with engine gearbox, and the crankshaft rear end output shaft is connected with high pressure oil pump, sealing axle sleeve bearing load or do not have stuffing box gland.
Known have front end axle sleeve, rear end bearing, a preposition oil-feed tail end outputting power air compressor; Preceding step bearing, rear end axle sleeve, rearmounted oil-feed tail end outputting power air compressor; Duplex bearing postposition (between the bearing) oil-feed tail end outputting power air compressor.
Known utility model patent 2547900Y is front end axle sleeve, rear end bearing, preposition oil-feed tail end outputting power air compressor, and the front end axle sleeve is a bearing load.Known preceding step bearing, rear end axle sleeve, rearmounted oil-feed tail end outputting power air compressor; The rear end axle sleeve is a bearing load.Owing to there is the high load alternate load; The alloy sleeve eccentric wear is further developed into alloy sleeve and the bent axle pine is spacious, causes the interior recirculating oil quantity of casing bigger than normal, and air compressor is scurried oil.
Known duplex bearing postposition (between the bearing) oil-feed tail end outputting power air compressor, bigger than normal because of oil-feed fitting surface sectional area, recirculating oil quantity is bigger in the bent casing of air compressor.Air compressor is scurried oil.Can't reach state of equilibrium preferably because of the structural limitations bent axle simultaneously, vibrating noise is big under certain rotating speed, and Master Cost is higher.The crankcase complex process.
Summary of the invention:
The purpose of this utility model is to provide a kind of front end oil-feed air compressor of duplex bearing band sealing configuration, and bent axle and stuffing box gland adopt Spielpassung, also is to suspend during operation; Air compressor be can effectively solve and oil, tail end leakage of oil scurried; It is simple in structure, can improve the used air compressor reliability of diesel engine, the feature of environmental protection, and also processing and assembling is good.
The technical solution of the utility model is achieved in that a kind of front end oil-feed air compressor of duplex bearing band sealing configuration, comprises crankcase, flange, cylinder cap assembly, cylinder body, fore bearing, rear bearing, bent axle and place in the cylinder body driving pistons reciprocating by bent axle; The input shaft of the front end of described air compressor crank is connected with engine gearbox, and the crankshaft rear end output shaft is connected with high pressure oil pump, and fore bearing and rear bearing hold the receptor as load; It is characterized in that the fore bearing place of the input shaft of the front end of air compressor crank is provided with stuffing box gland, has filler opening on sealing axle sleeve; Fore bearing place band sealing axle sleeve can be an axle sleeve or directly by the sealing that is slidingly matched of flange and crankshaft journal; The stuffing box gland material is can be the steel backing composite bearing, oil-containing powder metallurgy, rubber, high-abrasive materials such as plastics; Crankcase body and flange can adopt split type or monolithic construction.
Good effect of the present utility model is that it is fit to relatively bad working environments, guarantees that air compressor is not more than specified recirculating oil quantity, makes the interior trapped fuel of crankcase less; Effectively solve air compressor and scurry oil, tail end leakage of oil; Simple in structure, can improve the used air compressor reliability of diesel engine, the feature of environmental protection.And processing and assembling is good.
