Spiral-rod engine

 

(57) Abstract:

The engine is designed for use in engine. The engine includes a housing, pistons, rods and the output link, representing a gear wheel. Stems are set against each other can be rotated around its axis during longitudinal movement on the outer surfaces of the rods are made form a polyhedron spiral surface, some of which are in contact with the body, and the other with the output link between the past and the spiral surfaces are freewheel for one-way torque transfer. Kinematic link in contact with the helical surfaces made in the form of rolls. The invention provides increased efficiency. 1 C.p. f-crystals, 2 Il.

The invention relates to energy, namely heat engines that convert the kinetic energy of the expanding gases from the burning fuel into mechanical work. For engines in which the longitudinal movement of the piston from the pressure of the expanding gases is converted into rotational motion of the output link. The invention can be used in any mechanism that converts the longitudinal motion of the piston in WrestleMania internal combustion engine, which cylinders having pistons are located on the same axis opposite each other and are interconnected by a rod. In the middle of the rod connected to the crankshaft, which converts the translational motion of the pistons into rotational motion of the flywheel (see as/with 118471).

The disadvantage of the above construction is that when a piston stroke, the crankshaft can only be done right away and for the further rotational movement is required to use the working stroke of the other piston or stored rotational energy of the flywheel. This disadvantage is present in all devices using a crank mechanism to convert linear motion into rotational motion.

A known design of mechanisms in which to convert the translational motion of the float into a rotary movement of the gears, use the rod with helical grooves having the opposite direction (see a/C 1032210 and Soviet patent 2653, CL 88 B3 1923).

The disadvantage of these designs is that when reverse motion of the float and rod, gear after stopping also starts to rotate in the opposite direction. In addition, the high specific pressure is awseme invention aims at eliminating the above drawbacks, and from its use can be obtained the following technical result is an increase in efficiency of the piston engine by increasing the frequency of rotation of the output section during longitudinal movement of the piston during the stroke.

This technical result is achieved due to the fact that in a helical-rod engine, the rods are placed against each other can be rotated around its axis during longitudinal movement on the outer surface of each of which is arranged a spiral surface opposite directions, one of which is through the kinematic relationship in contact with the body, while others in the same way, with the output link. Between the latter and the spiral surface is overrunning one-way torque transmission. The kinematic connection between the helical surfaces forming the polyhedron, and the housing is carried out by means of shafts mounted in the housing on bearings. The kinematic connection between the helical surfaces of the opposite direction and the output link is also carried through the shaft and through the freewheel.

In Fig. 1 shows a General view of the rod is, is orsna 2, 3 with the rods 4, 5, which are located against each other can be rotated around its axis during longitudinal movement. On the outer surface of the rods 4, 5 are made of spiral surfaces 6, 7 of the opposite direction. Spiral surface in contact with the respective shafts 8, which are kinematic link, allowing you to interact with some of the spiral surfaces 6 with the housing 1, the other spiral surfaces 7 of the opposite direction with the clutch 10 and the output element is a gear wheel 9. Between the output link and spiral surfaces 7 installed together with the kinematic link couplings 10, 11 free-wheeling one-way torque transmission.

Spiral-rod engine proposed construction works, i.e. converts the reciprocating motion of the piston into rotational motion of the output link is as follows: the piston 2 moves longitudinally from the influence of the expanding gases from the burning fuel-air mixture or from the pressure of other energy sources (water, steam, gas, liquid) supplied to the cylinders of the engine. The piston moves accordingly rods 4, 5, which are due to contact of the spiral is the treatment of each rod 4, 5 rotates the corresponding coupling 10, 11, and found them engaged gear wheel 9. Couplings 10, 11, contacting established therein shafts 8 (kinematic link) with spiral surfaces 7 of the opposite direction, also rotate from the force, moving each rod 4, 5. Due to the fact that the couplings 10, 11 and the gear wheel 9 to rotate with the rod and rotated independently from the interaction of the spiral surfaces of the opposite direction, the angle of rotation is doubled.

For designs where the steps of the spiral surfaces of the left 6 and right 7 directions are equal and the working stroke of the piston 2, 3 equal step spirals, the gear wheel 9 will make two full revolutions for one complete stroke of the piston. For comparison, used in the design of reciprocating internal combustion engines Converter reciprocating motion of the piston-crank mechanism) into rotational motion of the output link (flywheel), allows one full stroke of the piston to rotate the output link only half of turnover.

The conversion efficiency of the longitudinal force, moving the piston the mineral surfaces and stroke, you can change the end result. With increasing step spiral planes the number of revolutions of the output level decreases, and the torque increases. Conversely, the torque decreases with decreasing step spiral surfaces, and the number of revolutions of the output level increases.

To return the piston 2, the piston rod 4 and the coupling 10 to the initial position for repeating actions, longitudinally moves the piston 3. When his movement as the movement of the piston 2, there is a transformation of the longitudinal force in the rotation of the output element 9, which does not change its direction of rotation, because here in the kinematic chain contains a freewheel, which transmits torque in one direction only.

The proposed construction of a spiral rod engine allows to significantly improve the efficiency and reliability of heat engines in which the longitudinal movement of the piston is converted into rotational motion of the output link. Increased efficiency means getting more mechanical work while using less fuel, which in St. the wasp quantity of exhaust gases and reduce their toxicity.

The use of the invention in thermal power plants will allow you to reuse used in steam turbines to rotate the generator of electric current and to produce it in addition to produced by the turbines.

Very effective is the application of the technical solutions in the construction of engines, external combustion, where after the stroke necessary for the piston to stop for cooling the working fluid.
