Abstract

The utility model relates to a rolling operation engine, particularly a reciprocating internal combustion piston engine. The utility model solves the problems that pistons and piston rings of existing engines bear huge side pressure during the process of power stroke to result in friction loss which affects fuel economy and provides an engine which achieves rolling operation outside a cylinder. A piston is provided with a bracket, and a steel rail slide way or a ball bearing is fixed outside the cylinder. The side pressure acting on the piston and a piston ring is converted into the contact pressure of the bracket and the ball bearing or the contact pressure of the steel rail slide way and the ball bearing through the bracket, and in this way, prime large slide friction loss is converted into small rolling friction loss under the condition of same pressure to increase fuel economy. The rolling operation engine can save fuel and increase the life time of the cylinder, the piston and the piston ring.

Rolling-operation engine

Technical field

The utility model belongs to the machine power field, relates to internal combustion shaped piston reciprocating type motor, particularly a kind of motor of rolling-operation.

Background technique

Existing internal combustion shaped piston reciprocating type motor, be converted in the power stroke that rotatablely moves of bent axle by connecting rod and crank at oscillating rectilinear motion with piston, because connecting rod and piston are not point-blank, according to the resolution of forces principle, the huge thrust that the combustible substance of gasification produces when burning expansion can be to piston, piston ring produces a side pressure of pressing to cylinder wall, and under the high temperature and high pressure environment in cylinder, cylinder wall and piston, between the piston ring because thermal effect, its friction factor also can not be ignored, like this, piston, sliding friction loss between piston ring and the cylinder wall is quite remarkable, internal combustion engine thermal efficiency is reduced greatly, fuel economy is very low, has also influenced cylinder, piston, the life-span of piston ring.For reducing this frictional loss, there is the technician to take up to reduce the friction factor of cylinder and piston, piston ring, in November, 2004, domestic media was transmitted Xinhua News Agency's Pekinese's special despatch news demonstration, " Germany " Business " publishes article recently and points out; " Germany Utility Engineers laser exposure cylinder bearing face, make its surface vaporization, and its molten layer solidifies the working surface that the back produces and has ceramic characteristics, i.e. Zui Jia flatness.The researcher claims that this technology can make engine fuel consumption descend 75% at most, and makes cylinder bearing face and wear of piston-rings reduce by 90%.As yet do not see relevant report for rolling with the technological scheme that reduces this frictional loss and reduce side pressure or change to slide.

The purpose of this utility model is exactly the frictional loss that causes at above-mentioned side pressure, a kind of rolling-operation engine is provided, side pressure between piston, piston ring and the cylinder wall is converted into the contact pressure of cylinder outer rolling operation, thereby reduce the frictional loss between piston, piston ring and the cylinder wall, improve fuel economy, improve the life-span of cylinder, piston, piston ring.

The purpose of this utility model is achieved through the following technical solutions:

Rolling-operation engine, comprise cylinder, piston, piston ring, connecting rod, bent axle, piston is enclosed within the cylinder, piston ring is between piston and cylinder, connecting rod, crank, bent axle is movable connection, the position parallel with piston axis also has and the fixing rail chute of engine body on the described motor, fixed-site with its parallel axes on the piston has at least two supports, transverse axis is installed between the support, transverse axis has two branches, forms four ends, and every end is equipped with conveying mechanism, piston rolls with the rail chute by this conveying mechanism and is connected, and transverse axis is movable the connection with connecting rod.

Described conveying mechanism is a ball bearing, and every end of transverse axis has two ball bearings, the interior cover of ball bearing and transverse axis drive fit, and the rail chute is between the overcoat of two ball bearings.

Or the every end of described transverse axis is horizontally installed with two ball bearings, and ball bearing is in a side of support, and another ball bearing is at the opposite side of rail chute.

The purpose of this utility model can also realize by following another scheme:

Rolling-operation engine, comprise cylinder, piston, piston ring, connecting rod, bent axle, piston is enclosed within the cylinder, piston ring is between piston and cylinder, and connecting rod, crank, bent axle are movable connection, and described motor also comprises and the fixing conveying mechanism of engine body, be fixed with support with its parallel axes or position overlapped on the piston, support passes at least two conveying mechanisms, and transverse axis is arranged on the support, and connecting rod is movable the connection with it.

Described support is at least two, and transverse axis is therebetween, and between these two ball bearings, the distance between these two ball bearings is more than or equal to the distance of a stroke of piston in the position on the support at least two ball bearings on the every support, transverse axis.

Or described support is one, has in its both sides that at least two connecting rods and transverse axis are movable to be connected, at least two ball bearings on the support, and transverse axis is between these two ball bearings, and the distance between the ball bearing is more than or equal to the distance of a stroke of piston.

The elongation line of the crankshaft center line skew piston center line of above-mentioned two described rolling motors of scheme.Crankshaft center line is 1/2 of a crank radius to the distance that power stroke bears the opposite direction skew piston center line elongation line of side pressure, and the ratio of crank-connecting rod is taken as 1/5.

The beneficial effects of the utility model are, after adopting above-mentioned conveying mechanism, to act on piston originally by support, the side pressure of piston ring is converted between ball bearing and the rail chute or the active force between support and the ball bearing, be both contact pressures, piston like this, side pressure on the piston ring can reduce to zero in theory, according at the certain situation lower slider frictional force of friction factor and the proportional relation of pressure, as seen piston, the sliding friction loss of piston ring can be reduced to minimum, and between ball bearing and the rail chute or be the rolling-operation mode between support and the ball bearing, its force of rolling friction is significantly smaller than original force of sliding friction, thereby the rolling friction loss also is significantly smaller than original sliding friction loss.Therefore, by said structure, rolling-operation engine can reduce frictional loss 80%～90%, improves fuel economy, saves fuel oil 30～60%, and in about 5 times of the working lifes of raising cylinder, piston, piston ring, manufacture cost reduces more than 30%.
