Description

Crankless internal-combustion engines

Technical field:

The utility model has related to a kind of internal-combustion engine.Especially relate to a kind of crankless internal-combustion engines.

Background technique:

At present, crankshaft ﹠ connecting is all adopted in the reciprocal transmission of internal-combustion engine.This reciprocal kind of drive power loss is big, and conversion efficiency is low, and conversion efficiency only reaches about 40%, and transmission is not steady, and transmission speed is inhomogeneous, and parts are easy to wear.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of conversion efficiency height is provided, stable drive, and transmission speed is even, the nonabradable crankless internal-combustion engines of parts.

The purpose of this utility model is achieved in that a kind of crankless internal-combustion engines, comprise cylinder, piston and reciprocal driving mechanism, piston places in the cylinder, the one end links to each other with reciprocal driving mechanism, be characterized in that reciprocal driving mechanism comprises half tooth frame and half tooth axle, half tooth axle places in the half tooth frame, meshes with half tooth frame.

Internal-combustion engine is in expansion stroke, and the power that piston linear moves downward passes to half tooth axle by half tooth frame, makes the rotation of half tooth axle, obtains kinetic energy; In exhaust stroke, half gear changes into the power of half tooth frame moving linearly with the kinetic energy that obtains in the expansion stroke, and half tooth frame promotes piston and moves upward, and discharges combustion gas; In breathing process, half tooth axle changes into the power of half tooth frame moving linearly with the kinetic energy that obtains in the expansion stroke, makes half tooth frame drive piston and moves downward the inspiration mixed gas; In compression stroke, half tooth axle changes into the power of half tooth frame moving linearly with the kinetic energy that obtains in the expansion stroke, makes half tooth frame drive piston and moves upward compressed mixed gas.From expansion stroke, move in circles so again, finish the entire work process of internal-combustion engine.

Because the utility model is in power transmission process, the operative orientation of power is all the time perpendicular to the diameter of axle, and therefore half tooth frame institute work can change into the kinetic energy of half tooth axle fully in expansion stroke; And in exhaust stroke, suction stroke and compression process, only need to consume littler energy, and can finish three strokes, so the transformation efficiency height, running is steady, and transmission speed is even, and parts are not easy to wear.

Embodiment:

As Fig. 1～4, the utility model is a kind of crankless internal-combustion engines.Mainly form by cylinder 1, piston 2 and reciprocal driving mechanism 3.Piston 2 places in the cylinder 1, and the one end is linked to be an integral body with reciprocal driving mechanism 3 stationary phase.

As Fig. 5, back and forth driving mechanism 3 is made up of half tooth frame 3.1 and half tooth axle 3.2.Half tooth frame 3.1 is surrounded by forward and backward frame 3.1.1,3.1.3 and left and right tooth bar 3.1.2,3.1.4 and forms an integral body.Its preceding frame 3.1.1 is fixedlyed connected with piston 2 rear ends.Half tooth axle 3.2 places in the half tooth frame 3.1, with the left tooth bar 3.1.2 or the right tooth bar 3.1.4 engagement of half tooth frame, 3.1 inboards.

Transmission principle:

A, expansion stroke

When piston 2 moved to peak, the contact points of left tooth bar 3.1.2 and half tooth axle 3.2 was in minimum point, and this moment, left tooth bar 3.1.2 and half tooth axle 3.2 began engagement, and right tooth bar 3.1.4 and half tooth axle 3.2 begin to break away from, as Fig. 1.Mixture combustion expands and does work, the power that piston 2 acquisitions move downward, engagement by left tooth bar 3.1.2 and half tooth axle 3.2, the power that piston 2 straight lines are moved downward passes to half tooth axle 3.2 by left tooth bar 3.1.2, half tooth axle 3.2 is rotated counterclockwise, obtain kinetic energy, right tooth bar 3.1.4 is also along with left tooth bar 3.1.2 moves downward together.That is whole half tooth frame, 3.1 downward moving linearlies, as Fig. 2.

B, exhaust stroke

When piston 2 moved to minimum point, the contact points of left tooth bar 3.1.2 and half tooth axle 3.2 peaked, and the combustion gas acting finishes, and this moment, right tooth bar 3.1.4 and half tooth axle 3.2 began engagement, and left tooth bar 3.1.2 and half tooth axle 3.2 begin to break away from, as Fig. 3.Engagement by right tooth bar 3.1.4 and half tooth axle 3.2, the kinetic energy that half tooth axle 3.2 is obtained in a expansion stroke process changes into the power of right tooth bar 3.1.4 moving linearly, because being rotated counterclockwise of half tooth axle 3.2 makes right tooth bar 3.1.4 promote piston 2 and moves upward, and discharges combustion gas.Left side tooth bar 3.1.2 is also along with right tooth bar 3.1.4 moves upward together.That is whole half tooth frame 3.1 moving linearly upwards, as Fig. 4.

C, suction stroke:

When piston 2 moved to peak, the contact points of right tooth bar 3.1.4 and half tooth axle 3.2 touched the bottom, and this moment, left tooth bar 3.1.2 and half tooth axle 3.2 began engagement, and right tooth bar 3.1.4 and half tooth axle 3.2 begin to break away from, as Fig. 1.Engagement by left tooth bar 3.1.2 and half tooth axle 3.2, the kinetic energy that half tooth axle 3.2 is obtained in a expansion stroke process changes into the power of left tooth bar 3.1.2 moving linearly, because being rotated counterclockwise of half tooth axle 3.2 makes left tooth bar 3.1.2 drive piston 2 and moves downward the inspiration mixed gas.Right tooth bar 3.1.4 is also along with left tooth bar 3.1.2 moves downward together.That is whole half tooth frame, 3.1 downward moving linearlies, as Fig. 2.

D, compression stroke:

When piston 2 moved to minimum point, the contact points of left tooth bar 3.1.2 and half tooth axle 3.2 peaked, and this moment, right tooth bar 3.1.4 and half tooth axle 3.2 began engagement, and left tooth bar 3.1.2 and half tooth axle 3.2 begin to break away from, as Fig. 3.Engagement by right tooth bar 3.1.4 and half tooth axle 3.2, the kinetic energy that half tooth axle 3.2 is obtained in a expansion stroke process changes into the power of right tooth bar 3.1.4 moving linearly, because being rotated counterclockwise of half tooth axle 3.2 makes right tooth bar 3.1.4 promote piston 2 and moves upward compressed mixed gas.Left side tooth bar 3.1.2 is also along with right tooth bar 3.1.4 moves upward together.That is whole half tooth frame 3.1 moving linearly upwards, as Fig. 4.

From a expansion stroke, move in circles so again, finish the entire work process of internal-combustion engine.
