Abstract
The utility model relates to a shaft bushing type bearing cap. A pair of main shaft bushings are added on the basis of a crankshaft bearing of the original diesel engine, a fixing baffle plate 2 is arranged at the inner side of a main shaft neck, a fixing screw hole 3 is arranged on the baffle plate, a bearing cap 5 is fixedly arranged on the baffle plate, a bearing 6 is installed at the left inner side of the bearing cap, the main shaft bushings are arranged at the right inner side of the bearing, an oil seal 8 is arranged at the outer side of the main shaft bushings, a flywheel 9 is arranged at the outer side of the oil seal, and the flywheel is fixed on a shaft head of the crankshaft through a nut 11 and a locking piece 10. The utility model can cause the service life of the crankshaft and the bearing to be increased to 7000 hours from 1500 hours, and has the advantages of simple structure, convenience, and easiness.
Description
The utility model relates to a kind of crankshaft bearing cap of diesel engine.
The S1110 diesel engine of Xiao Shouing in the market, because crankshaft main journal has adopted Bearing Installation, its rolling bearing running resistance is little, and is light and handy, flexibly, and positive effect has all been played in the starting and the fuel-economizing of unit.But at first, bearing is worked under high temperature, high pressure, fast state for a long time, the working life and the safety that all directly have influence on diesel engine because of the bearing capacity and the intensity of bearing.Secondly, be positioned at the lubricated main oil gallery on the main journal, rely on the bearing cap sealing of cast iron, in case when bearing has wearing and tearing slightly, the bearing cap of sealing oil duct will aggravate wearing and tearing, make the oil pressure reduction of main oil gallery, thereby aggravate the damage and wear of crank mechanism more.Therefore, brand-new motor is often only through 1400-1500 hour work, just because of the too early replacing of the wearing and tearing of bearing bent axle, bearing and bearing cap, cause unnecessary loss and burden to the user.
The purpose of this utility model provides a kind of split sleeve bearing lid, makes it increase the single raise main axle bush again on the basis of original bearing, with works fine state that guarantees unit and the working life that prolongs bent axle.
Scheme of the present utility model is made up of bent axle, baffle plate, bearing cap, bearing, main axle bush, oil sealing, flywheel etc., and its structure is the fixed dam of installed inside at crankshaft main journal, and plate washer is provided with fixing threaded hole, and bearing cap is fixed on the baffle plate.Bearing is positioned at the outside of baffle plate, and a left side that is installed in bearing cap is inboard, and main axle bush is positioned at the outside of bearing, is installed in the right inner side of bearing cap, and the main oil gallery that bearing shell just in time is sealed on the main journal exports.The bearing cap inner edge that will be positioned at the main axle bush position strengthens 5-15mm, makes bearing shell be mated installation.Oil sealing is equipped with in the outside of bearing shell, and flywheel is equipped with in the outside of oil sealing, and the outside of flywheel locks with nut and locking plate.
The utility model has the advantages that simple, practicality, reasonable in design, increase cost hardly, can make unit durability prolong 3-5 doubly.
Be described further below in conjunction with accompanying drawing:
Accompanying drawing is a split sleeve bearing lid scheme of installation.
Among the figure, baffle plate 2 is installed in the inboard of crankshaft main journal 1, baffle plate is provided with fixing threaded hole 3, bearing cap 5 is fixed on the baffle plate by screw 4, bearing 6 is installed in the inboard, a left side of bearing cap, and main axle bush 7 is installed in the right inner side of bearing cap, and oil sealing 8 is equipped with in the outside of main axle bush, flywheel 9 is equipped with in the outside of oil sealing, and flywheel is fixed on the bent axle spindle nose by nut 11 and locking plate 10.The bearing cap inner edge that will be positioned at the main axle bush position earlier strengthens 5-15mm, makes bearing shell be mated installation.Because bent axle main oil gallery mouth is by original cast iron bearing lid sealing, change the main axle bush sealing of using Babbitt into, therefore increased the working life of crankshaft journal greatly, moreover behind the bearing bush abrasion, therefore replaceable increasing 0.25,0.5 or 0.75 increasing watt extended to 6000-7000 hour by original 1400-1500 hour the working life of a bent axle.
Claims (2)
1, a kind of split sleeve bearing lid, form by bent axle, baffle plate, bearing cap, bearing, main axle bush, oil sealing, flywheel, it is characterized in that: fixed dam (2) is equipped with in the inboard of crankshaft main journal (1), baffle plate is provided with fixing threaded hole (3), bearing cap (5) is fixed on the baffle plate, bearing (6) is installed in the inboard, a left side of bearing cap, main axle bush (7) is installed in the right inner side of bearing cap, oil sealing (8) is equipped with in the outside of main axle bush, flywheel (9) is equipped with in the outside of oil sealing, and flywheel is fixed on the bent axle spindle nose by nut (11) and locking plate (10).
