After motorcycle used a period of time, the valve rocker of motor and valve were through long-term wearing down, and the valve clearance will be increasing, therefore need adjust valve.The most frequently used valve clearance adjusting method is at present: at first unclamp the hold-doun nut of valve adjustments screw, the feeler gauge of predetermined thickness is inserted the place, valve clearance, the pull feeler gauge rotates adjusting screw with hand on the other hand then, till feeler gauge is subjected to resistance a little.Adjust appropriate after, feeler gauge is inserted into valve clearance central authorities, it is motionless that adjusting screw keeps, and tightens hold-doun nut locking adjusting screw.After locking screw, remeasure the valve clearance with feeler gauge again, because when locking, may rotate adjusting screw unintentionally, the valve clearance is changed.If the valve clearance changes, should readjust correct till.
Above valve adjusting method is carried out with operator's feel and qualification, and not only accuracy is relatively poor, and needs the instrument feeler gauge of specialty, can't guarantee disposable adjusting, and needs to carry out adjustment repeatedly sometimes, complex operation, and the time that spends is long.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and can carries out fast and the nut of precisely regulating the motorcycle valve clearance.
Technological scheme of the present invention is as follows: a kind of for the adjusting nut of adjusting the motorcycle valve clearance, has nut body (1), end face at least one end of described nut body (1) is provided with by the equally distributed bisectrix of circumference (2), the center of circle of described bisectrix (2) circumference that surrounds is 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 at the end face of adjusting nut, accordingly, sets up four grooves on the adjusting screw.When assembled engines, earlier adjusting screw and adjusting nut zero clearance are fixed, because four grooves on the adjusting screw evenly distribute by circumference, therefore has a groove at least in the face of the user, then with the wherein bisectrix on the corresponding adjusting nut of this groove of facing the user, this bisectrix is just as start index, and the user just can adjust adjusting screw then, make the groove on the adjusting screw correspond to the demand bisectrix, screw adjusting nut then and get final product.After regulating, can also verify whether adjust correctly by the bisectrix table on the adjusting nut.The present invention matches with groove on the adjusting screw by the bisectrix on the adjusting nut, can intuitively show regulated quantity, to realize the accurate adjusting to the valve clearance, and it is simple, convenient, quick, the adjustment means that neither needs specialty, operator's qualification is required not high yet, even new hand also can be accurately, expertly grasp.
End face at described nut body (1) two ends is equipped with bisectrix (2), and the bisectrix at two ends (2) is symmetrical, does not have the direction requirement when like this adjusting nut being installed, and makes assembling easier, quick.
As preferably, the number of the bisectrix (2) on described nut body (1) end face is the 10-30 bar.
Processing and fabricating makes indication valve clearance regulated value more accurate for convenience, and 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.
Beneficial effect: the present invention can precisely regulate the valve clearance, neither needs the adjustment means of specialty, operator's qualification is required not high yet, characteristics such as it is ingenious to have a design, implements easily, simple, convenient, quick.

Embodiment
The invention will be further described below in conjunction with drawings and Examples:
Referring to Fig. 1, the present invention has nut body 1, and the external frame of this screw thread body 1 is hexahedron, and the center has screw.End face at described nut body 1 at least one end is provided with by the equally distributed bisectrix 2 of circumference, and in the present embodiment, the end face at nut body 1 two ends is equipped with bisectrix 2, and the bisectrix 2 at two ends is symmetrical.The center of circle of the described bisectrix 2 of the same end face circumference that surrounds is 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 number of the described bisectrix 2 of same end face is the 10-30 bar, and present embodiment is preferably 20.Bisectrix 2 can be the shallow slot that is 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 Fig. 2, shown in Figure 3, the adjusting screw that matches with the present invention has screw body 3, and the enlarged diameter section at screw body 3 middle parts is processed with outside thread, and flight pitch is preferably 1mm.The circumferential surface of described screw body 3 major diameters upper end is provided with four by the equally distributed groove 4 of circumference, and each groove 4 is extending axially along described screw body 3 all.The width of groove 4 notches is preferably 1mm, and the length of groove 4 and the degree of depth are determined according to actual needs.
Working principle of the present invention is as follows:
When assembled engines, earlier adjusting screw and adjusting nut zero clearance are fixed, because four grooves 4 on the adjusting screw evenly distribute by circumference, therefore having a groove 4 at least is in the face of the user's, then with wherein bisectrix 2 of facing on these groove 4 corresponding adjusting nuts of user, this bisectrix 2 is just as start index, the user just can adjust adjusting screw then, make the groove 4 on the adjusting screw correspond to demand bisectrix 2, screw adjusting nut then and get final product.After regulating, can also verify whether adjust correctly by the bisectrix table on the adjusting nut.
Because the flight pitch of adjusting screw is 1mm, so this adjusting screw is revolved the 1mm that only advances and retreat that turns around.Utilize this characteristic, with respect to the bisectrix of adjusting nut, just can give every bisectrix definition a gap adjusted value.Be example with 20 of bisectrixs, the scale of every bisectrix is 1/20mm=0.05mm.For example producer's regulation valve clearance is 0.3mm, and adjusting screw turns over 6 bisectrixs and gets final product so.When precision prescribed was more high, the number that only needs to improve bisectrix got final product.
After motorcycle uses after a while, in the time of need regulating the valve clearance, can regulate relative valve clearance with reference to aforesaid way, do not give unnecessary details at this.
