Problems solved by technology

[0004] The above valve adjustment method depends on the operator's feel and proficiency. Not only is the accuracy poor, but also requires professional tool plug gauges, and it cannot be guaranteed to be adjusted at one time. Sometimes multiple adjustments are required, and the operation is cumbersome. long time

Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0016] see figure 1 , the present invention has a nut body 1, the outer contour of the threaded body 1 is a regular hexagon, with a screw hole in the center. On the end surface of at least one end of the nut body 1, there are equisectors 2 uniformly distributed on the circumference. Relatively symmetrical. The center of the circle surrounded by the bisectors 2 on the same end surface is on the axis of the nut body 1 , and the extension lines of each bisector 2 intersect the axis of the nut body 1 . The number of bisectors 2 on the same end face is 10-30, and in this embodiment, it is preferably 20. The bisector 2 can be a shallow groove formed on the end surface of the nut body 1, and the width of the shallow groove is preferably 0.1 mm; the bisector 2 can also be a scratch or a drawn line.

[0017] Such as figure 2 , image 3 As shown, the adjusting s...

Abstract

The invention discloses an adjusting nut used for adjusting motorcycle air valve clearance. The adjusting nut comprises a nut body (1). The end face of at least one end of the nut body (1) is provided with bisectrices (2) which are evenly distributed in a circumference mode. The center of the circumference formed through enclosure of the bisectrices (2) is located on the axis line of the nut body (1). Extension lines of all the bisectrices (2) intersect with the axis line of the nut body (1) respectively. The adjusting nut can accurately adjust the air valve clearance, specialized adjusting tools are not needed, requirements for proficiency of an operator are not high either, and the adjusting nut used for adjusting the motorcycle air valve clearance has the advantages of being ingenious in design, easy to implement, and simple, convenient and rapid to operate.

Description

technical field [0001] The invention relates to a nut, in particular to an adjusting nut for adjusting the gap of a motorcycle valve. Background technique [0002] Valve clearance is critical to the performance of a motorcycle engine. Excessive valve clearance: after the intake and exhaust valves are opened late, the intake and exhaust time is shortened, the valve opening height is reduced, and the normal valve timing is changed, so that the engine power decreases due to insufficient intake air and dirty exhaust , and the noise of the engine is too loud. In addition, the impact of the parts of the valve train is increased and the wear is accelerated. The valve clearance is too small: After the engine is working, the parts are heated and expanded and the valve is pushed open, so that the valve is not closed tightly, resulting in air leakage, the engine power is reduced and it is easy to turn off, so that the sealing surface of the valve is seriously deposited or burned, and ...
