Description
Technical field
The utility model relates to the motorcycle engine field, particularly a kind of accessory that is used for the installation of motorcycle engine oil sealing.
Background technology
The combustion machine part of most of motorcycle engine links together with running part, engine power transfers out by bent axle → main shaft → driving shaft, the bent axle of engine, main shaft, driving shaft all are to be installed on the crankcase by bearing, for power is transferred out, one end of driving shaft must stretch out outside the crankcase, external part at driving shaft is processed with spline, be used to install the drive sprocket transferring power, end at spline is processed with an annular groove, be used for installing back-up ring, prevent that drive sprocket from coming off.Go out in order to prevent lubricating oil leakage, an oil sealing is installed in the crankcase of bearing outer end, and oil sealing and driving shaft, crankcase all are interference fit, when the assembling oil sealing, common way be earlier with oil-sealing sleeve on driving shaft, with an accessory oil sealing is pressed in the oil sealing hole of crankcase then.
Oil sealing mainly is to realize sealing by the interference fit between oil seal lip and the driving shaft, if oil sealing is installed as stated above, oil seal lip is easy to be hung by annular groove mashed through the annular groove position on the driving shaft time, and the spring in the oil sealing also drops easily.Simultaneously, hang, between oil sealing and bearing, certain interval should be arranged for avoiding wiping mutually between oil sealing and the bearing; because general accessory does not have stopping means; after assembling, the situation that oil sealing and bearing are wiped extension mutually appears through regular meeting, and engine operation a period of time rear bearing can be with the oil sealing intertrigo.Owing to above reason, oil sealing can lose sealing function, oil impregnate appears in engine in running, oil impregnate not only can make the engine outer surface greasy dirt occur, influence attractive in appearance, thereby and make the excessive influence of consumption of lubricating oil lubricated to engine, will make engine scuffing when serious, engine shuts down suddenly, causes personal injury accident.
Summary of the invention
The purpose of this utility model provides a kind of engine oil seal accessory is installed, and it can make engine oil be enclosed in to keep lip intact in the installation, and the spring in the oil sealing does not drop, and guarantees that sealing is reliable.
For reaching above-mentioned purpose, the utility model design one cover accessory, comprise the accessory A that has blind hole, the diameter of the blind hole of this accessory A satisfies and driving shaft outer end diameter of axle matched in clearance, its degree of depth greater than driving shaft outer end end face to crankcase oils sealing of hole outboard end face apart from 2mm.Other has an accessory B, and it is bullet-shaped to be thin-walled, and hole dimension satisfies and driving shaft outer end diameter of axle matched in clearance in it, and its length is greater than the length of driving shaft outer end end face to crankcase oils sealing of hole outboard end face; The bullet end of described accessory B is taper or hemispherical, and the other end is cylindrical.
Described accessory B wall thickness is 0.3-0.5mm.
Described accessory A perforate end has a step, and its diameter is less than the oil sealing external diameter, and width is 0.5-1mm, and all the other shaft section diameters are greater than the oil sealing external diameter.
The beneficial effect of such scheme is: can guarantee that oil sealing lip in installation process is intact by the extension wound, spring does not drop, and can not interfere with bearing, guarantees to seal reliably.
Description of drawings
Fig. 1 is that oil sealing is installed in the structural representation on the motor driven axle.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the scheme of installation of oil sealing.
The specific embodiment
Referring to Fig. 1, Fig. 3, engine power is by driving shaft 5 outputs, driving shaft 5 is installed between crankcase 1 and 2 by bearing 4 and 3, the outside that oil sealing 10 is installed in bearing 3 is in the oil sealing hole of crankcase 2, the left end of driving shaft 5 has spline 7 and stretches out crankcase 2, drive sprocket 9 is installed on the spline 7, and back-up ring 15 is installed in the annular groove 8 of spline 7 ends.
Referring to Fig. 2, accessory described in the utility model is made up of accessory A12 and accessory B11, wherein the blind hole diameter of accessory A12 satisfies and driving shaft 5 outer end diameter of axle matched in clearance, its degree of depth greater than driving shaft 5 outer end end faces to crankcase 2 oil sealing holes outsides end face apart from 2mm, accessory A12 perforate end has a step 14, its diameter is less than oil sealing 10 external diameters, width is 0.5-1mm, all the other shaft section diameters are greater than oil sealing 10 external diameters, the purpose of step 14 is to prevent that oil sealing 10 was pressed into dark in assembling process and bearing 3 is interfered, and guarantees to leave the gap between oil sealing and the bearing 3.It is bullet-shaped that accessory B11 is thin-walled, and wall thickness is 0.3-0.5mm, and hole dimension satisfies and driving shaft 5 outer end diameter of axle matched in clearance in it, and its length is greater than the length of driving shaft 5 outer end end faces to crankcase 2 oil sealing holes outside end face; The bullet end of described accessory B11 is taper, and its head diameter is convenient to oil sealing 10 assemblings less than oil sealing 10 lip diameters, and the other end is cylindrical.
Referring to Fig. 3, during assembling oil sealing 10, earlier accessory B11 is enclosed within on the driving shaft 5, support bearing 3, the front end that then oil sealing 10 is enclosed within accessory B11 is a tapering point, the rear end that slides to accessory B11 lentamente is a cylindrical end, and pin oil sealing 10 with a hand this moment, and the another hand is extracted accessory B11, oil sealing 10 just can be avoided annular groove 8 like this, avoid the lip of oil sealing 10 mashed, successfully be installed on the driving shaft 5, and then accessory A12 is enclosed within on the driving shaft 5 by annular groove 8 extensions, knocking accessory A12 with hammer 13 presses to oil sealing 10 in the oil sealing hole of crankcase 2, the extension phenomenon can not take place to wipe because the position-limiting action of step 14 leaves the gap between oil sealing 10 and the bearing 3 in this moment.
