The present invention is a isolator gear rack driving engine which causes the power output of the engine to be converted to a design that the gear rack is engaged with isolator teeth. On one hand, an original crankshaft connection rod piston structure is maintained so that the motion law of the engine is constant, and the present invention assures that gas distribution, oil supply or an ignition system normally operates according to original laws; on the other hand, power is output through the gear rack of the isolator so that the rotation moment of a work application stroke at arbitrary moment is in a position of the maximum value of an engine shaft.

Description

A one-way gear rack drive engine

Technical field

The invention relates to an engine, in particular to a rack drive engine with a one-way device.

Background technique

The piston-connecting rod crankshaft engine is widely used at present, and the more advanced one is the triangular piston rotary engine. Both types of engines have advantages and disadvantages. The piston connecting rod crankshaft engine has good air tightness, but due to the inertial effect of the connecting rod crankshaft moving at high speed, the whole machine vibrates greatly; When the piston moves downward, the torque change gradually increases from zero to the maximum value (when the crankshaft turns from the top dead center to 90°) and gradually decreases from the maximum value to zero (the crankshaft continues to turn from 90° to the bottom stop Points), go round and round to complete the stroke of the engine. The advantage of the triangular piston rotary engine is that the torque is at the maximum value of the crankshaft at any moment of the power stroke, so the output is large, but the problem of air tightness is difficult to solve.

Contents of Invention

The purpose of the present invention is to provide a kind of one-way gear rack drive engine with good airtightness and the torque at any moment in the power stroke, which can overcome the problems of the above two types of engines and greatly improve the performance of the engine. engine performance.

In order to achieve the above object, the technical scheme adopted by the present invention is as follows: comprising a piston installed in the cylinder, a connecting rod connected with the piston pin, and a crankshaft connected with the connecting rod. The piston pin is also connected to the rack, which meshes with the teeth of the first one-way device. The two ends of the first one-way device shaft are respectively equipped with an output disc with a flywheel and a second one-way device connected with the crankshaft. Timing gear is housed on the other end, and crankshaft, the first one-way device axle all are contained on the body.

Said first one-way device and second one-way device are overrunning clutches or ratchets.

Compared with the background technology, the present invention has the beneficial effect that: the piston engine converts the reciprocating motion of the piston into the rotation of the crankshaft through the connecting rod and the crankshaft mechanism. The present invention changes the power output of the engine so that the gear rack is engaged with the teeth of the one-way device (that is, an overrunning clutch or a ratchet) and designs a one-way gear rack drive engine. On the one hand, the original crankshaft, connecting rod and piston structure is maintained, so that the motion law of the engine remains unchanged, ensuring that the gas distribution, fuel supply or ignition systems work normally according to the original law; The torque at any moment of the stroke is at the maximum value of the crankshaft.

Detailed ways

As shown in the drawings, the present invention includes a piston 2 installed in the cylinder, a connecting rod 3 connected with the piston pin 1 , and a crankshaft 8 connected with the connecting rod 3 . A rack 4 is also connected to the piston pin 1, and the rack 4 meshes with the teeth of the first one-way device 7. The two ends of the shaft of the first one-way device 7 are respectively equipped with an output disc 6 with a flywheel 5 and a crankshaft 8 connected to each other. Second one-way device 9, timing gear 11 is housed on the other end of crankshaft 8, crankshaft 8, first one-way device 7 axles all are contained on the bearing 12 of body 10.

The course of work of the present invention is as follows: connect two parts, connecting rod 3 and rack 4 on the piston pin 1. The connecting rod 3 is connected with the crankshaft 8, which changes the reciprocating motion of the piston 2 into the rotary motion of the crankshaft, drives the timing gear 11, and makes the gas distribution, oil supply or ignition system of the engine work normally according to the original law. The teeth of the rack 4 and the first one-way device 7 (which is an overrunning clutch or a ratchet) mesh. When the piston 2 moves to the bottom dead center, the rack 4 pushes the first one-way device 7 to rotate, and transmits the power to the output disk 6 for output; when the piston 2 moves from the bottom dead center to the top dead center, the rack 4 drives the first The outer ring of the one-way device 7 rotates idly, and the output disk 6 keeps the original rotation direction. The first one-way device 7 transmits power when it rotates forward, and idles when it is reversed, and does not transmit power, so that the torque at any moment of the power stroke is at the maximum value of the crankshaft. The effect of the second one-way device 9 is to transmit the inertial force of the flywheel 5 to the crankshaft linkage, so that it can operate normally.
