Abstract

A mechanism for converting reciprocatory oscillating motion to rotary motion comprises a yoke 25 pivotally supported, about a first axis X, in a housing and to be oscillated about said first axis via piston connecting rods (23) (Fig 1), a bearing housing 20 having arms 57, 58 and pivotable by the arms in respective bearings in the yoke arms 56, 59, an inclined crank (18) having an inclined shaft (9) rotatably supported in the bearing housing, the inclined crank (18) being rotatably supported about a second axis in the housing whereby reciprocatory motion of the yoke about the first axis is converted to rotary motion of the crank (18) about the second axis. The mechanism allows for the point of connection of the connecting rods (23) with the yoke 25 to be varied to vary the output torque on the crank 18. <IMAGE>

Description

BaCr;GROIJ:;i) OF ICI The invention relates to a reciprocating piston internal combustion engine and, more particularly, to the inclined crankshaft. All well known engines and electric motors are adapted to drive vehicles, industrial machines and domestic appliances, without generating an additional torque. This invention is devised to generate an additional torque.

An experimental test, conducted on 11 ;ay 1989, employing a yoke in the form of a lever in conjunction with the inclined crankshaft and a wobble bearing housing block, proved successful. The crank on the inclined shaft is arranged at a 450 angle relative to the longitudinal shaft axis. A connecting rod from the reciprocating piston is connected to the push pin, designed to swing the yoke on its pivot in a reciprocating manner, instead of the conventional crankshaft.

The yoke with its two arms, forces the two bars arranged on the bearing housing block to swing. The swinging action of the two bars, via wobble housing block, forces the crank of the inclined shaft to twist, causing it to rotate.

SUMMARY OF Tt INVENTION It is an object of the present invention to provide the reciprocatin internal combustion engine with a greater torque transmission by connecting the rod from the reciprocating piston to a push pin on the yoke. The yoke acts as a lever which produces approximately 5/ö more torque. It works only in combination with the inclined shaft, a wobble bearing housing block and a yoke.

Another feature of the invention is the turnable push pin in a bearing housing of the yoke which can be displaced for higher torque in the engine.

Another feature of the invention is the nut and bolt which are replaced with a more advanced arrangement to prevent unlocking in vibrating engines.

THIGH TORQUF ISCE ISr, The embodiment of the invention will now be described by way of example with reference to the accompanying drawings.

Fig. 1 illustrates the mechanism with the piston connected to a yoke and the inclined crankshaft in the bearing housing.

Fig. 2 shows the yoke with arms, mounted on the demountable bearing housing boss, fitted in the body.

Figs. 3 and 4 illustrate the variable positions of the push pin and the differential of pressure between a push pin and the output shaft.

Figs. 5 and 6 are views of the radial key lock.

Figs. 7, 6, 9, 10, 11 and 12 show the spring bolt fastener.

On Fig. 1 is a sectional view of a multi cylinder reciprocating piston, internal combustion engine, comprising of embodi-nt 1, a cover plate 2, with plurality of cylinders 3 and reciprocating piston 4. The opposite end of the embodiment is the view of the bearing housing 6, comprising bearings 7 and 11 and separator 10, closed with cover plate 12.

An apperture 17, in the embodiment is arranged with countersink 9, into which the bearing housing enters, secured with nuts 16. An inclined shaft 18 is mounted into the bearing housing, fitted on the end with driving gears 14 and 13.

A crank 19, is arranged on the inclined shaft forming a solid part.

A rotatable bearing housing block 20, comprising two bearings 21 and 22, of similar type to previous patent no. 2163229, is mounted on a crank.

The reciprocating piston is connected with connecting rod 23, to a push pin 24. The push pin is turnable on the yoke 25.

On Fig. 2 is shown an exploded part of the yoke, and another push pin 26.

The push pin is inserted from the lower part of the yoke into bearings 27 and 31, located on the countersinks 32 and 33, followed by a spacing washer 34 and connecting rod 35. To prevent strain on the inner race rings of the two ball bearings, radial key lock 36 has been fitted.

On Fig. 5, is shown the radial key lock, comprising two radial keys 37 and 38 and a capsule 39. The radial key is fitted into a wide and deep groove 41, which protrudes high above the diametrical surface 42. The side of the groove is aligned with the machined face of the connecting rod 35, with respect that when two radial keys are fitted into the groove, there is no slack. If slack exists the spacing washer 34, must be replaced. A capsule 39 mounted on top of two radial keys, prevents the radial keys from falling out of the groove, see Fig. 6. A circular clip 43, see Fig. 12, is fi:d into undercut 40, preventing the capsule from sliding out. A small gap 44 between the capsule and the connecting rod will prevent the circular clip from straining.

Fig. 2 shows a yoke having a pivot 45 mounted on two bearings 46 and 47, arranged in the demountable bearing housing boss 48, which is fitted in the countersink 49, in the embodiment. Thrust bearing 50 and suitable needle thrust bearing covered with the capsule 51, fastened with nut 52, will keep the yoke in a still position.

When the engine is in action, the reciprocating pistons and connecting rods swing the yoke in a reciprocating manner on the demountable bearing housing boss 48.

Numbers 5, 8, 15 and 53 are oil seal rings.

The bearing housing block 20 is arranged with two bars 57 and 58 mounted turnable on the bearings in arms 56 and 59, preventing the bearing housing from rotating with the inclined crankshaft. On one end of the yoke the arm 56 is demountable. The arm is arranged with a tooth 28 and a groove 30 which fit into the groove 60 and the tooth 61 on the yoke, see Figs. 3 and 4.

Reverting back to Fig. 2, this shows that strain and vibration caused by the demountable an , when using the conventional bolt, which fastens the arm with the yoke, would not be secure. Therefore, a spring bolt 29 has been devised to prevent the bolt from unlocking.

On Fig. 7, is shown a bolt 29 with a circular rim 62, with one, two (or more) holes 63 and 64, for drilling guidance purposes.

Fig. 10 shows a part of the demountable arm and bolt fastened to a yoke.

To prevent an accidental unlocking of the fastened bolt, a hole 65 is drilled through the hole on the rim into the yoke to a requited depth.

A wired and hardened clip 66, see Fig. 9, is pushed into the drilled hole and meshed with the hole on the rim of the bolt, as shovwrl on Figs. 10 and 11. The wired clip is then pressed on to a groove 67 arranged around the hexagon head of the bolt, until it clicks. ne bolt, in this way, will stay secure from unlocking.

A demountable bearing housing boss, see Fig. 2, is fastened from outside the embodiment with circular head spring bolts 54, see Fig.13, and fixed with the sane procedure as hexagon bolts. Fig. 8 shows a a washer with a hexagon hole and a drill hole to suit a conventional hexagon bolt, which would be cheaper to use.

The parts of the torque mechanism can be assembled outside the embodiment. The inclined shaft mounted in the bearing housing, situated inside the embodiment, is not fastened with a bolt, because it is locked by the two bars 57 and 58 mounted in the arms 56 and 59.

Figs. 3 and 4 illustrate a yoke in central position marked b, which rocks on the axis x-x. A push pin stroke from d to e equals half a turn of the inclined shaft and the yoke will swing from a to c (and vice verso) on a 90 angle.

An experimental test made on 11 ay 1989, proved that if a pressure of 1 kg. is directed onto the push pin situated on the yoke in h position (shown on Fig. 4j then the pressure on the end of the inclined shaft fitted with a crank having the same stroke as the push pin, will produce a pressure of 1.5 kg.

A similar experimental test was arranged on a conventional crankshaft.

A pressure of 1 kg. was directed onto the crank from the reciprocating piston in h position, then the pressure on the end of the output shaft, fitted with a crank having the same stroke as the crank connected to the reciprocating piston, produced a pressure of 1 kg. only.

If the push pin is in a g or f position then the pressure on the output shaft will be higher. It works like a lever in combination with the inclined shaft and a yoke. Therefore, it is unllke a conventional crankshaft.
