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

Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment

[0013] The present invention is described further:

[0014] Such as Figure 1 to Figure 2 As shown, a new type of camshaft includes a camshaft 1, a sprocket 2 and a fixed seat 3, the sprocket 2 is fixed to one end of the camshaft 1 through the fixed seat 3, and the sprocket 2 is provided with a first screw hole 4 and a scale 5. The fixed seat 3 is provided with an arc-shaped through hole 6 corresponding to the first screw hole 4, and the fixed seat 3 is provided with an indicator part 7 corresponding to the scale 5. The screw 8 passes through the arc-shaped through hole 6 and is connected with the first screw hole 4.

[0015] The fixed seat 3 is provided with a protruding part 31, and the arc-shaped through hole 6 is arranged on the protruding part 31. The end of the protruding part 31 is provided with an indicating part 7 corresponding to the scale 5, and the number of the protruding parts 31 is 3-6. One...

Abstract

The invention discloses a novel cam shaft. The novel cam shaft comprises a cam shaft, a chain wheel and a holder, wherein the chain wheel is fixed with one end of the cam shaft through the holder, a first screw hole and scales are arranged on the chain wheel, an arc-shaped through hole is formed in the part, corresponding to the first screw hole, of the holder, an indication part is arranged at the part, corresponding to the scales, of the holder, and the screw penetrates through the arc-shaped through hole and is connected with the first screw hole. The arrangement of the scales is increased on the cam shaft, the relative position of the cam shaft to the chain wheel is regulated through matching the scales with the indication part, the regulating range of the time sequence difference between a piston and a valve is increased to realize a fine adjustment effect, and at the same time, the regulating 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...
