Abstract

The utility model discloses a screw-type piston motor or engine. An energy-saving machine is formed by combining a screw, a piston, a rolling ball nut and a thruster, the diameter and pitch of the screw are reduced, so that the motion distance of the piston is reduced so as to reduce the motion volume of the piston in a cylinder and further realize multiple effects of double acceleration and double energy conservation; besides, the diameter of the piston and the radial size of the thruster are increased to enlarge the working pressure and the torque, and finally generate high speed and large torsion under a low energy consumption condition.

Description

A kind of bolt type piston motor or motor

Technical field

The utility model relates to a kind of power plant, is applicable to pneumaticpiston motor, hydraulic piston motor and fuel type piston engine.

Background technique

Current air pressure motor, oil hydraulic motor and crankshaft type motor all want high energy consumption could produce at a high speed large torsion, particularly air pressure motor, oil hydraulic motor is the most outstanding, and its basic reason is all relevant with the interior movable volume of piston cylinder.Large piston produces large torsion and at a high speed, yet large piston is wanted large energy consumption, and for air pressure or oil hydraulic motor, large piston has just directly strengthened the internal volume of piston cylinder, and the infusion time that makes gas or liquid lengthens and reduced speed.With regard to current common crankshaft piston type motor, be that straight-line piston converts circular movement after by crankshaft link rod motion to and completes air-breathing, compression, burning expansion and four strokes of exhaust, with this, circulate and constantly carry out work.Open the throttle is to strengthen engine horsepower the most directly, the most rapidly and the most effective approach, yet structurally, the horsepower that promotes motor will be improved and could be realized on the movable volume (discharge capacity) of piston cylinder and the circumferential running radius of bent axle, because the circumferential running radius of bent axle is speed and the torsion that directly affects motor; And according to lever principle: if strengthen crankshaft operation radius, although this can strengthen torsion, speed increases with crankshaft operation radius and slack-off inversely; Bent axle circumferential running diameter is exactly its piston linear operating path length, so along with the increase of bent axle circumferential running radius, the movable volume of piston internal combustion cylinder also significantly increases, thereby has significantly strengthened energy consumption thereupon; If oversize piston cylinder diameter, although this is a best approach that directly strengthens working pressure, has also significantly strengthened energy consumption simultaneously.As can be seen here, current common bent axle piston engine has but increased energy consumption and has underspeeded when increasing torsion, and described underspeeding refers to that piston linear operating path lengthens in crank throw increasing the speed that is lowered; In the time that working pressure will be increased, equally also to significantly increase energy consumption; And when wanting pick up speed, must dwindle bent axle circumferential running radius, and can reduce so again torsion, at this moment need to strengthen working pressure to make up, can increase energy consumption so too.In sum, current piston type air oil hydraulic motor and crankshaft type piston engine will add high-power can only realization by increasing energy consumption, this is also that current bent axle piston engine is weighed the main cause of horsepower standard by discharge capacity, therefore current bent axle piston engine horsepower is larger, and energy consumption is also larger.
