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] like figure 1 , figure 2 As shown, the present invention is composed of a large cylinder 1, an adjustment column 2 and a top column 3. The adjustment column 2 is a square column, and the adjustment column 2 is located at the central position of the top surface of the large cylinder 1, and is arranged at the center of the bottom surface of the large cylinder 1. The top column 3, the large cylinder 1, the adjustment column 2 and the top column 3 are integrally structured, and the axis lines of the three are on a straight line. Threads are processed on the circumferential surface of the large cylinder 1, and the pitch of the threads is preferably 1mm. The circumferential surface of the upper end of the large cylinder 1 is provided with four grooves 4 evenly distributed on the circumference, and each groove 4 extends axially along the large cylinder 1, ...

Abstract

The invention discloses an adjusting screw for adjusting the valve clearance of a motorcycle. The adjusting screw is composed of a large cylinder (1), an adjusting column (2) and a prop column (3), the adjusting column (2) is arranged in the center of the top surface of the large column (1), the prop column (3) is arranged in the center of the bottom surface of the large column (1), threads are arranged on the circumferential surface of the large column (1), four grooves (4) which are distributed evenly in the circumferential surface are formed in the upper end of the large column (1), and the grooves (4) extend along the large column (1) axially. By means of the adjusting screw, the valve clearance can be adjusted accurately, specialized adjusting tools are not needed, and the requirements for the proficiency of operators is not high. The adjusting screw for adjusting the valve clearance of the motorcycle has the advantages of being ingenious in design, easy to implement, simple convenient and fast to operate, and the like.

Description

technical field [0001] The invention relates to a screw, in particular to an adjusting screw used for adjusting the valve clearance of a motorcycle. 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 ...
