Embodiment
See figures.1.and.2 the bearing support that is used for flywheel of the present utility model.Bearing support pedestal 7 is made up of base and the sleeve that is welded on the base, and base roughly is " recessed " font, and base is provided with the bolt hole of using when fixing this base, and the axial end of sleeve is provided with bolt hole and is used to connect end cap.The bearing support pedestal is provided with tank filler sleeve, the lubricating cup 8 that connects this tank filler sleeve of sealing in this tank filler sleeve, be provided with first bearing device and second bearing device that are used to connect flywheel shaft in the bearing support pedestal 7, first bearing device and second bearing device are locked in the bearing support pedestal by left end cap 4 and right end cap 11 respectively, and left end cap is fixedlyed connected with bearing support pedestal 7 by bolt respectively with right end cap.Left end cap and/or right end cap are provided with oil outlet, connect the jettison gear of this oil outlet of sealing in the oil outlet, and jettison gear comprises the nuion nut 1 of draining the oil of draining the oil and taking over 1a and being connected with this adapter of draining the oil.Be provided with oil circuit 1b on bearing support pedestal 7, the adapter 1a that drains the oil is threaded in this oil circuit.Left end cap is provided with the first secondary lip oil sealing 3, and right end cap is provided with the second secondary lip oil sealing 12.Also be provided with first circlip 2 that is positioned at first secondary lip oil sealing 3 one sides on the left end cap 4, circlip 2 is fixed in the groove on the left end cap.The left side of the first secondary lip oil sealing 3 and circlip 2 against, the groove face of the groove of right side and left end cap against, the left end by 3 pairs of bearing support pedestals of the first secondary lip oil sealing seals.Similarly, the right-hand member by 12 pairs of bearing support pedestals of the second secondary lip oil sealing seals.Also be provided with second circlip 13 that is positioned at second secondary lip oil sealing 12 1 sides on the described right end cap 11.
First bearing device comprises clutch shaft bearing 5, and first packing ring 6 that is positioned at clutch shaft bearing one side.Clutch shaft bearing 5 is outer aligning thrust ball bearing, and 5 pairs of flywheel shafts of clutch shaft bearing can play the effect of aligning, makes its axle center and bearing support keep concentric.Clutch shaft bearing 5 one ends carry out axial limiting by the step that is provided with in the bearing support pedestal, and its other end carries out axial limiting by first packing ring 6.First bearing device is to use like this: first packing ring 6 is fastened on the flywheel shaft 14, clutch shaft bearing 5 is interference fitted on the flywheel shaft.
Described second bearing device comprises second bearing 9 that is positioned at first packing ring, 6 opposite sides, and second packing ring 10 that is positioned at the second bearing opposite side.First packing ring 6 plays compartmentation to these two bearings between the clutch shaft bearing 5 and second bearing 9.Second bearing is a selfaligning ball bearing, and second bearing mainly bears the radial load of flywheel shaft, and also can automatically carry out aligning to flywheel shaft.Similarly, the mode of the assembling of second bearing device and flywheel shaft 14 and first bearing device is identical.
Some problems that note in the bearing support using process:
1) bearing holder component needs to make regular check in the flywheel using process, and the scope of examination comprises:
◆ whether bearing support in use has abnormal sound
◆ bearing holder component in use whether temperature too high (mainly with hand feel be as the criterion, stand should quit work at once when the sensation hand scalded one's hand especially, to the bearing holder component inspection.)
◆ whether bearing holder component in use has unusual vibrations
Solution:
◆ bearing holder component mainly contains following reason in use if any abnormal sound:
Lubricant pollution causes inner body relative movement face that fine particle is arranged, and destroys oil lamella, produces abrasive wear.Solution is in time used kerosene bearing cleaning seat inner chamber oil change more then.
◆ bearing support is temperature too high (hand is touched when the bearing support sensation scalds one's hand especially and illustrated that the bearing support temperature is too high) in use, mainly by following reason:
◆ bearing holder component is in use if any unusual vibrations, mainly since bolt looseness or fracture cause, should in time check the pretightening force of bolt, and in time change the bolt of fracture.
2) method in the flywheel using process, safeguarded of bearing holder component:
◆ add lubricant oil to bearing support: turn on lubricating cup 8, add the lubricant oil of about 300ml inside.The every accumulation work of bearing holder component 200h (perhaps per two months) must add a lubricant oil.
◆ give the bearing support oil change: at first prepare swab case, use two spanners then, one maintaining oil discharge screw, and another turns on the nut 1 of draining the oil, and after oil is all put totally inside treating, tightens the nut of draining the oil; Next turn on the lubricant oil that lubricating cup 8 adds about 800ml inside.Bearing support is after assembling (comprise first to use and change later on maintenance such as bearing), and more behind the oil change, every 1000h (perhaps 8 months) is oil change more through break-in.
◆ the state of component such as inspection bearing: take the left end cap 4 of bearing support apart, method for dismounting is as follows, after the clamping bolt on the bearing cover is pulled down, screw bolt with two M8 * 60, put into and open the top screw,, slowly twist nut and be ejected until bearing cover as Fig. 2.
◆ adjust the pretightening force of bearing: after bearing cover is taken out, take out packing ring 6, when bearing pre-fastening is excessive, suitably reduce gasket thickness, when bearing pre-fastening was excessive, making packing ring 2 again suitably increased thickness.
