The utility model is composed of a crankshaft, a loose roller, a loose roller frame and a pushing rod. The utility model can be used in various occasions. When used on a piston, the utility model can overcome the defects existing in the prior art that the volume of equipment is large, a lateral direction between the piston and a cylinder wall is worn, etc. For an internal combustion engine, the utility model can provide definite rest time for a piston when the piston is positioned at a rest point, which can ensure that fuel which enters an air cylinder can be entirely burnt with the same high compression ratio, can effectively turn heat energy into mechanical energy and can create conditions for recovering and utilizing exhaust heat.

Description

Rotatablely move and the new drive device of linear reciprocating motion

The utility model belongs to a kind of mechanical transmission, a kind of transmission device that is specifically related to rotatablely move and changes mutually with linear reciprocating motion.

As everyone knows, before the utility model was made, what extensively adopt in the prior art of changing mutually with linear reciprocating motion that rotatablely moves was the crankshaft-link rod drive technology, for example application in piston.And there are several contradictions in this drive technology: the one, and connecting rod swing causes the side wear between piston and casing wall and the contradiction of volume.If connecting rod is directly linked to each other with piston (as: internal-combustion engine, single worker's air compressor etc.),, easily produce casing wall non-linear wearing and tearing along the circumferential direction, unfavorable sealing though can make equipment obtain smaller size smaller; If piston is connected (as: duplexing air compressor etc.) by axostylus axostyle (or claiming piston rod) with connecting rod, though can eliminate between piston and casing wall the side wear that the swing because of connecting rod causes, volume is more much bigger than the former.The 2nd, the vibration that alternation inertia causes, the contradiction of wearing and tearing and volume.The object of linear reciprocating motion has alternation inertia, though by reducing single chamber volume, increase the cylinder number, adopting balanced measure can eliminate impact shock, but the wearing and tearing that alternation inertia causes, the equipment that directly links to each other for piston and connecting rod is difficult to adopt impact mitigation measure further to reduce.Though can adopt impact mitigation measure to piston by the equipment that piston rod is connected with connecting rod, volume is more much bigger than the former.The 3rd, the contradiction of kinetic characteristic and economic benefit.As internal-combustion engine, make the heat energy that enters the fuel in the cylinder be transformed into mechanical energy efficiently, fuel is burnt under high as far as possible compression ratio, and must perfect combustion.Because the burning of fuel needs the regular hour, this just requires piston that a static time is arranged when top dead center, since the crankshaft-linking rod drive mechanism bent axle rotatablely move and reciprocating motion of the pistons between continuity, it can not provide a static time to piston, thereby can not guarantee that the fuel that enters cylinder fully burns, and can not be transformed into mechanical energy with heat energy efficiently.Also therefore can not adopt the waste heat recovery technology to improve the economic benefit of internal-combustion engine effectively.

The purpose of this utility model provides a kind of rotatablely moving and the new drive device of linear reciprocating motion, this mechanical transmission can use in multiple occasion, it can make and rotatablely move and linear reciprocating motion is changed mutually, if use on piston, it can reduction equipment volume, eliminate the wearing and tearing between piston and casing wall, simultaneously, also can adopt buffer technology further to reduce wearing and tearing; For internal-combustion engine, also can be piston be provided certain quiescent time when top dead center, can burning fully under same high compression ratio with the fuel that guarantees to enter cylinder, efficiently heat energy is transformed into mechanical energy, and has created condition for the waste heat recovery utilization.

The purpose of this utility model is finished by following technical proposals:

The utility model is a kind of rotatablely moving and the new drive device of linear reciprocating motion, and its structure outline is: this transmission device is made of bent axle, alien, rotator frame and push rod four parts that are connected on the edge of the rotator frame left and right sides; Crankshaft installed is on crankshaft base, and it is made up of main bottle neck, crank, inferior bent neck; Rotator frame and the alien in rotator frame are installed between two cranks of bent axle, and inferior bent neck connects with the alien, and the upper and lower position of rotator frame is provided with the loose slot of rotator frame.During work, bent axle is driven by power as driving shaft, drives the alien by inferior bent neck then and rotates simultaneously.Rotator frame does reciprocating linear motion in the rotator frame loose slot under alien's motion drives, if install piston at the two ends of push rod, push rod will promote piston and do reciprocating linear motion in cylinder, thereby reaches the purpose of this utility model.

The utility model in the specific implementation, the push rod sectional shape is circular or square.

The utility model in the specific implementation, alien's profile is square, rotator frame munnion limit internal surface is a plane shape.

The utility model in the specific implementation, alien's profile also can be cylindrical shape, the concave surface of rotator frame munnion limit internal surface is an arc.

Transmission device of the present utility model end is so far seen open report and public use, and it has the advantage that drive mechanism is reasonable, using effect is good, is used on the piston if this transmission device is substituted existing crankshaft ﹠ connecting, has following characteristics so:

1, bent axle, alien, the rotator frame driving mechanism that crank throw constitutes can promote two pistons simultaneously and carry out work, and the volume and weight of average single cylinder is little more many than crankshaft ﹠ connecting, and has eliminated the side wear between piston and casing wall.

2, alternation inertia ratio piston of the present utility model and the direct-connected equipment of connecting rod are big, but easily adopt buffer technology to reduce or eliminate its shock effect.If can eliminate cutting off most shock effect, can adopt a kind of form (that is: shared crank throw of the piston of multicylinder engine of common mode configuration fully as internal-combustion engine, each cylinder distributes by the angle that equates around bent axle, each cylinder can be less than the diameter in cylinder hole along the axial centre distance of bent axle), the volume and weight of motor is more reduced.

Can adopt buffer technology if 3 are used for two stroke engine, because of a cylinder is in expansion space stroke, another cylinder must be in compression stroke, is exactly buffering to piston inertia to the compression of gas.

4, the alien in the utility model adopts drum-shape, rotator frame munnion limit internal surface middle part to adopt concave arc shape, when the alien rolls at concave arc surface, piston will rest on top dead center and keep motionless, this just for the perfect combustion of fuel, efficiently heat energy is transformed into mechanical energy guarantee is provided, also for adopting the waste heat recovery reutilization technology to create advantage effectively.Because separated the period of combustion of fuel from compression time and power done time, this has just established technical foundation for the i.e. generation of five phase motors (operation cycle of motor is divided into intake period, compression period, burning phase, work done phase, exhaust cycle) or three phase motors (compression period, burning phase, work done phase) etc. of new high-efficiency internal-combustion engine.
