technical field

The utility model belongs to the field of generator equipment, in particular to an eccentric motor.

Background technique

Since the advent of the internal combustion engine, human beings have entered the era of using machinery to replace human labor. Engines are widely used in various mechanical powers, especially in transportation. But its structural improvements are not perfect. Wherein, in the existing engines, fuel combustion in the cylinder generally pushes the cylindrical piston to reciprocate, and the reciprocating motion is converted into rotational motion through the crankshaft of the connecting rod mechanism, thereby outputting power. Due to this structure, the horizontal thrust of the piston must be decomposed into the tangential force of the power transmission wheel. When the gas pressure is maximum, the torque is minimum. When the torque becomes larger, the gas pressure is greatly reduced, so the power loss is very large.

Utility model content

Aiming at the defects of the traditional cylindrical piston structure engine that the torque is the smallest when the gas pressure is the largest, and the power loss is large, the technical problem to be solved by the utility model is to provide an eccentric engine that has the largest torque when the gas pressure is the largest.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: an eccentric engine, including a cylinder body, an eccentric rotating wheel is arranged in the cylinder body, the eccentric rotating wheel is tangent to the cylinder body, and the eccentric rotating wheel It is connected with the power output shaft and can rotate around the power output shaft; the cylinder body is provided with an opening, and a partition is installed in the opening, and the partition board can slide in the opening; the cylinder body, eccentric rotating wheel The eccentric rotating wheel and the partition divide the space into two cylinders; the two sides of the opening are respectively equipped with an air intake device and an exhaust device, and a point is provided near the air intake device in the cylinder. fire device.

The cylinder body is circular, and the power output shaft is concentric with the cylinder body.

It also includes a pressing mechanism for pressing the partition against the eccentric rotating wheel, the pressing mechanism includes a spring, and the spring is connected with the partition.

The pressing mechanism also includes a spring fixing shaft, the spring fixing shaft is connected with the separator, and the spring is sleeved on the spring fixing shaft.

It also includes a base on which the cylinder body is installed.

The utility model has the advantages that when the gas pressure is the largest, the torque is also the largest, the mechanical efficiency is high, and the economic benefit is improved.

Fig. 1～3 is the structural representation of a kind of eccentric engine of the present utility model, comprises cylinder body 8, is provided with eccentric rotating wheel 3 in cylinder body 8, and eccentric rotating wheel 3 is tangent to cylinder body 8, and eccentric rotating wheel 3 and power output The shaft 4 is connected and can rotate around the power output shaft 4; the cylinder body 8 is provided with an opening, and a partition 7 is installed in the opening, and the partition 7 can slide in the opening; the cylinder body 8, the eccentric rotating wheel 3 and the partition The plate 7 forms a closed space, and the eccentric rotating wheel 3 and the partition 7 divide the space into two cylinders; the two sides of the opening are respectively provided with an air intake device 1 and an exhaust device 2, and an ignition device is provided near the air intake device 1 in the cylinder body 8 . device. The cylinder body 8 is circular, and the power take-off shaft 4 is concentric with the cylinder body 8 .

It also includes a pressing mechanism for pressing the partition plate 7 against the eccentric rotating wheel 3, the pressing mechanism includes a spring 5, and the spring 5 is connected with the partition plate 7. The pressing mechanism also includes a spring fixed shaft 6, which is connected with the partition plate 7, and the spring 5 is sleeved on the spring fixed shaft 6.

It also includes a base 9 on which the cylinder body 8 is installed.

Wherein the cylinder block 8 is fixed by the base 9, the power output shaft 4 is fixed on the eccentric rotating wheel 3, and one end of the spring 5 is fixed on the spring fixed shaft 6, and the spring fixed shaft 6 is fixed on the dividing plate 7. The eccentric wheel 3 is inscribed with the cylinder body 8 . Both ends of the power take-off shaft 4 protrude from the cylinder block 8 to fix its position. The power take-off shaft 4 is concentric with the cylinder block 8 . The eccentric wheel 3 always rotates with the power take-off shaft 4 as the axis. The eccentric wheel 3 is always in close contact with the inner wall of the cylinder body 8 during the rotation. The partition 7 divides the space formed by the cylinder body 8 and the eccentric wheel 3 into two parts. The partition 7 can move left and right due to the spring 5 .

When working, after the intake device 1 enters the mixed gas of fuel and air, the combustion produces high-temperature and high-pressure gas to push the eccentric rotating wheel 3 to rotate clockwise with the power output shaft 4 as the axis, and the eccentric rotating wheel 3 is always in contact with the cylinder during rotation The inner wall of the body 8 is close; when the tangent line between the eccentric rotating wheel 3 and the cylinder body 8 is transferred to the position of the partition plate 7, due to inertia, the eccentric rotating wheel 3 will continue to rotate clockwise; when the tangent line is transferred to the air intake device After 1, the intake device 1 will enter the mixed gas of fuel and air again, and the combustion will generate high-temperature and high-pressure gas to push the eccentric rotating wheel 3 to continue to rotate clockwise. At this time, the exhaust device 2 is opened to discharge exhaust gas. The eccentric rotating wheel 3 has just completed a cycle of forwarding like this, so reciprocating, the power output shaft 4 continuously outputs power.

After adopting such a structure, when the gas pressure is the largest, the torque is also the largest, the mechanical efficiency is high, and the economic benefit is improved.
