Description
Technical field
The present invention relates to a kind of nut, particularly for adjusting the adjusting nut of motorcycle air valve clearance.
Background technique
The performance of valve clearance to motorcycle engine is most important.Valve clearance is excessive: inlet and outlet door is opened and lagged, shorten the intake and exhaust time, reduce the Lift of valve, change normal port timing, make motor because air inlet is not enough, exhaust is unclean and power drop, and the noise of motor is excessive, in addition, also make the shock of distribution device part increase, wearing and tearing are accelerated.Valve clearance is too small: after engine operation, and valve is pushed open by part expanded by heating, and make valve-closing not tight, cause gas leakage, engine power declines and easily stops working, and makes the serious carbon distribution of the sealing surfaces of valve or burns out, even valve percussion piston.
After motorcycle uses a period of time, the valve rocker of motor and valve wear down through long-term, and valve clearance will be increasing, therefore need to adjust valve.Valve clearance adjusting method the most frequently used is at present: the hold-doun nut first unclamping valve adjustments screw, and the feeler gauge of predetermined thickness is inserted valve clearance place, and then pull feeler gauge rotates adjusting screw with hand, until feeler gauge is subject to resistance a little on the other hand.Adjust appropriate after, feeler gauge is inserted into valve clearance central authorities, adjusting screw keep motionless, tighten hold-doun nut locking adjusting screw.After locking screw, then remeasuring valve clearance with feeler gauge, because may be not intended to have rotated adjusting screw when locking, valve clearance being changed.If valve clearance changes, till should readjusting correctly.
Above valve adjusting method is carried out with the feel of operator and qualification, and not only accuracy is poor, and needs the instrument feeler gauge of specialty, and can't ensure disposable adjusting, sometimes need to carry out adjustment repeatedly, complex operation, the time spent is long.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of can carry out fast and the nut of precisely adjustment motorcycle air valve clearance.
Technological scheme of the present invention is as follows: a kind of adjusting nut for adjusting motorcycle air valve clearance, there is nut body (1), the end face of described nut body (1) at least one end is provided with circumferentially equally distributed bisectrix (2), described bisectrix (2) surround the center of circle of circumference on the shaft axis of nut body (1), and the elongation line of each bisectrix (2) is all crossing with the shaft axis of described nut body (1).
The present invention arranges bisectrix on the end face of adjusting nut, accordingly, adjusting screw is set up four grooves.When assembled engines, first adjusting screw and adjusting nut zero clearance are fixed, because the groove of four in adjusting screw is circumferentially uniformly distributed, therefore a groove is had at least in the face of user, then use the wherein bisectrix on the corresponding adjusting nut of this groove of user, this bisectrix is just as start index, and then user just can adjust adjusting screw, make the groove in adjusting screw correspond to demand bisectrix, then screw adjusting nut.After regulating, can also be verified by the bisectrix table on adjusting nut and whether adjust correctly.The present invention is by the bisectrix on adjusting nut and the fit depressions in adjusting screw, can vision-control amount directly perceived, to realize the accurate adjustment to valve clearance, and it is simple, convenient, quick, neither need the adjustment means of specialty, require also not high, even if new hand also can accurately, expertly grasp to the qualification of operator.
Be equipped with bisectrix (2) at the end face at described nut body (1) two ends, and the bisectrix at two ends (2) is symmetrical, there is no direction requirement when adjusting nut is installed like this, make assembling easier, quick.
As preferably, the number of the bisectrix (2) on described nut body (1) end face is 10-30 bar.
Conveniently processing and fabricating, make instruction valve clearance regulated value more accurate, described bisectrix (2) is for being formed at the shallow slot of nut body (1) end face, and the width of this shallow slot is 0.1mm.
The features such as beneficial effect: the present invention precisely can regulate valve clearance, neither needs the adjustment means of specialty, requires also not high, have design ingenious to the qualification of operator, implements easily, simple, convenient, quick.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of the adjusting screw matched with the present invention;
Fig. 3 is the plan view of Fig. 2.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
See Fig. 1, the present invention has nut body 1, and the external frame of this threaded body 1 is hexahedron, and center has screw.The end face of described nut body 1 at least one end is provided with circumferentially equally distributed bisectrix 2, in the present embodiment, be equipped with bisectrix 2 at the end face at nut body 1 two ends, and the bisectrix 2 at two ends is symmetrical.Bisectrix 2 described in same end face surround the center of circle of circumference on the shaft axis of nut body 1, and the elongation line of each bisectrix 2 is all crossing with the shaft axis of described nut body 1.Described in same end face, the number of bisectrix 2 is 10-30 bar, and the present embodiment is preferably 20.Bisectrix 2 can be the shallow slot being formed at nut body 1 end face, and the width of this shallow slot is preferably 0.1mm; Bisectrix 2 also can be cut or setting-out.
As shown in Figure 2 and Figure 3, the adjusting screw matched with the present invention has screw body 3, and the enlarged diameter section in the middle part of screw body 3 is processed with outside thread, and flight pitch is preferably 1mm.The circumferential surface of described screw body 3 major diameter upper end is provided with four circumferentially equally distributed grooves 4, and each groove 4 all extends along the axis of described screw body 3.The width of groove 4 notch is preferably 1mm, and length and the degree of depth of groove 4 are determined according to actual needs.
Working principle of the present invention is as follows:
When assembled engines, first adjusting screw and adjusting nut zero clearance are fixed, because the groove of four in adjusting screw 4 is circumferentially uniformly distributed, therefore a groove 4 is had at least to be in the face of user, then the wherein bisectrix 2 on the corresponding adjusting nut of this groove 4 of user is used, this bisectrix 2 is just as start index, then user just can adjust adjusting screw, make the groove 4 in adjusting screw correspond to demand bisectrix 2, then screw adjusting nut.After regulating, can also be verified by the bisectrix table on adjusting nut and whether adjust correctly.
Flight pitch due to adjusting screw is 1mm, and therefore this adjusting screw revolves the 1mm that only retreats that turns around.Utilize this characteristic, relative to the bisectrix of adjusting nut, define a gap adjusted value just can to every bar bisectrix.For bisectrix 20, the scale of every bar bisectrix is 1/20mm=0.05mm.Such as producer's regulation valve clearance is 0.3mm, and so adjusting screw turns over 6 bisectrixs.When precision prescribed is higher, the number of bisectrix only need be improved.
After motorcycle uses after a while, when needing to regulate valve clearance, can regulate relative valve clearance with reference to aforesaid way, therefore not to repeat here.
