Description

A kind of engine high-efficiency axial-rotation driving mechanism

Technical field

The utility model relates to a kind of engine high-efficiency axial-rotation driving mechanisms.

Background technique

The transmission device of conventional engines mainly uses crankshaft-linking rod drive mechanism, and principle is caused by fuel detonation The axial force on piston for driving it to move along a straight line is applied to by connecting rod and its is converted with the connection structure of crankshaft crank At the radial force of driving crankshaft rotary motion, since its structure is simply again perfect extremely mature by continuing to optimize for a long time, With relatively broad.

But it is known in industry, it is known that one very big problem of above-mentioned crankshaft-linking rod drive mechanism physical presence itself: by There is an angle always when the power of the rectilinear direction acted on piston passes to crankshaft crank by connecting rod, so that crankshaft What is obtained always in a rotational direction is the power being decomposed.Such case especially the initial stage of piston motion and latter stage very Obvious and extreme, when the direction of the power decomposed at this time is close to 90 degree, power can not almost be passed, according to acting calculation formula W= FS(F is power, and S is distance), it is understood that a big chunk power is wasted in the case where the time is constant.So passing The output power of system engine is really the power obtained after being decomposed.Therefore the energy of most conventional engines turns at present Changing efficiency can only achieve 35% or so, also waste while people bring people's convenience using above-mentioned conventional engines The huge energy.

For the purpose for promoting engine power transfer efficiency, applicant had previously had developed a kind of novel driving engine Device, and declared related patents.The core of this transmission device be exactly devise a kind of axial-rotation driving mechanism replace it is normal The crankshaft-linking rod drive mechanism of rule, this axial-rotation driving mechanism, which passes through to be axially moved above component at work, tilts closed loop The driving trenched side-wall of design pushes the roller motion of rotary motion component, enables rotary motion component continuous rotation, from And the continuous rotation that the linear motion of piston is converted to engine output revolving shaft is moved.During being somebody's turn to do, the power of piston output Direction is changed simply by axial-rotation driving mechanism, and is absolutely not decomposed, seldom a part of frictional force is removed, it is big absolutely Partial power is delivered to output revolving shaft output.And starting point and the end dead point area very little of piston acting, most of energy It is utilized.Therefore, from the transfer efficiency of its energy for the structure of itself much higher than conventional crankshaft-linking rod drive mechanism.

But it constantly brings forth new ideas and improved theory in line with technology, mistake of the research staff in the above-mentioned axial-rotation driving mechanism of application Cheng Zhong gropes by practice, it is found that it still has following urgently improved place:

1) the lighter should design in the weight principle of axial movement component in axial-rotation driving mechanism the better, in favor of The energy loss of engine piston acting is further decreased, improves energy conversion efficiency, and reducing mechanism is vibrated.And mitigate component On the one hand the method for weight can use light material, such as aluminium etc., but should also take into account the hardness and strength of material simultaneously, with The driving groove of phase thereon can support impact force and friction of the idler wheel in high speed reciprocating motion under by engine piston driving Power.By practice we have found that existing routine aluminium etc. light materials often intensity is inadequate, the driving groove of manufacture be difficult to Impact force and frictional force of the idler wheel in high speed reciprocating motion under by engine piston driving.Thus at present feasible approach also It is to need to manufacture using the relatively high material of intensity to be axially moved component and driving groove thereon, such as bearing steel etc., The mainly tolerance of enhancing driving groove, cooperation reduction are axially moved the method for the structural volume of component in weight and strong Reach balance between degree.But we have found that the quality for being axially moved component is still heavier in practice.

This is because existing axial-rotation driving mechanism will drive trench design on being axially moved component, due to take into account The occupied area of groove is driven, therefore the existing volume for being axially moved component is almost difficult further to reduce.With current We are applied to for the axial-rotation driving mechanism on 200cc engine, the axial movement component of the bearing steel making of use Weight still reaches 1.2kg after optimization design, then for the engine of 200cc, the axial movement structure of the weight Vibration of the part in inner working or biggish.

2) single idler wheel is designed in existing axial-rotation driving mechanism to act on simultaneously with driving groove two side walls, it is real Border operate when, idler wheel drive groove inner circumferential move back and forth when specific node exist commutate, that is, need from driving groove One side wall face contact roll and be changed into suddenly and contact rolling with another side wall surface, while idler wheel also rotates in the opposite direction.Due to The inherently high-speed rotating state of idler wheel, not only difficulty is larger for commutation, and certainly will cause to generate friction between idler wheel and wall surface, that It is really very big for the abrasion of idler wheel in this way.

3) guiding mechanism in existing axial-rotation driving mechanism uses the fit form of sliding guide sleeve and guide post, and slides It is sliding friction between dynamic guide sleeve and guide post, frictional force is larger, leads in mechanism operation process that still there are certain energy damages It loses, this is for improve the mechanism that energy conversion efficiency is main functional purpose, it is clear that needs to improve.
