Problems solved by technology
Usually the sprocket is fixed on the camshaft by screws, so when the user needs to adjust the timing difference between the piston and the valve, the large part of the engine must be disassembled, and then the large part must be reinstalled after adjusting the sprocket angle. The adjustment process is complicated, which is not conducive to construction. At the same time, each adjustment is adjusted in units of pitch, so it cannot be adjusted to a non-integer timing difference such as 0.5 pitch, and the adjustment will be greatly affected. limit

Abstract
The invention discloses an adjustable cam shaft structure which comprises a cam shaft, a chain wheel and a fixing seat. The chain wheel is fixed to one end of the cam shaft through the fixing seat. The chain wheel is provided with first screw holes and scale marks. Arc-shaped through holes are formed in the positions, corresponding to the first screw holes, of the fixing seat. Indication parts are arranged on the positions, corresponding to the scale marks, of the fixing seat. Screws penetrate the arc-shaped through holes to be connected with the first screw holes. According to the adjustable cam shaft structure, the scale marks are additionally arranged on the cam shaft and matched with the indication parts to adjust the relative position of the cam shaft and the chain wheel, the fine adjustment effect is achieved by enlarging the timing sequence difference of a piston and a valve, and the adjustment process is simplified.
Description
technical field [0001] The invention relates to a camshaft. Background technique [0002] The operation of a general locomotive engine is mainly through the combustion of gasoline in the combustion chamber, thereby driving the piston to reciprocate, and through the rotation of the sprocket to form a linkage with the camshaft, and the rotation of the sprocket will rotate with the crank rotation generated by the reciprocating motion of the piston. The piston and the valve operate synchronously in sequence through the linkage of the cycle, so that the opening and closing of the intake and exhaust valves can cooperate with the piston. Usually the sprocket is fixed on the camshaft by screws, so when the user needs to adjust the timing difference between the piston and the valve, the large part of the engine must be disassembled, and then the large part must be reinstalled after adjusting the sprocket angle. Installing, the adjustment process is complicated, which is not conduciv...
