Definitions

  • Mechanism for converting a reciprocating movement into a rotational movement and vice versa and device comprising such a mechanism.
  • This invention relates to a mechanism for converting a reciprocating movement into a rotational movement and vice versa, device comprising such a mechanism, method of making and use of such a mechanism or device.
  • Application of such mechanisms is e.g. in
  • this document describes a mechanism whereby the connecting rod is attached eccentrically to a gear wheel, the gear wheel being mounted on a crank and turnable in a stationary ring with internal teeth.
  • the movement of the connecting rod is rectilinear, it is not easy to install the ring with internal teeth in the engine block. Also the fabrication costs of such a ring are relatively high. Furthermore, a crankshaft is still needed which is complicated to make.
  • a connecting rod connects to a crank between two eccentrically arranged gear wheels with sliding bearings. These gear wheels are engaged with an eccentrical gear wheel having a fixed bearing and are kept into engagement with connecting elements which are formed around the outer circumference of the eccentrical wheels. Apart from the enormous friction that occurs, the connecting elements do not move rectilinearly but like a pendulum and cause beside the connecting rods extra vibrations.
  • DE-A-3232974 describes a mechanism for converting a reciprocating movement into a rotational movement and vice versa, using at least three gearwheels one of which is freely rotatable around the axis through its centre.
  • One embodiment shows the connection of the wheels to three crankshafts, which are difficult to manufacture.
  • Another embodiment shows the freely rotatable wheel being provided at its rotational axis through its centre with a difficult to produce crankshaft.
  • the other wheels are coupled in their rotation by further means in the form of a surrounding belt.
  • This belt establishes only a frictional connection between the wheels, which allows for slip of the belt and relative movement of the centres of the wheels with respect to each other, especially when the belt tension is decreasing due to wear, resulting in a malfunctioning of the mechanism.
  • DE-A-4430423 describes a similar mechanism using two excentrically rotating gear wheels, only one having a fixed excentrical rotating axis, whereby the wheels are kept engaged by a connecting rod connecting the centres of the wheels.
  • a third gear wheel can be arranged for guiding the freely rotating wheel (the wheel which has no fixed rotating axis). How this third wheel is kept engaged with the other wheels is not disclosed and it is even recommended not to use three (or more) wheels.
  • Other embodiments show rods with grooves in which pins are guided which result in enormous frictional losses. Always connections are provided at the rotational axis through the centre of the freely rotating wheel resulting in extra friction losses and limitations to connect the reciprocating member at both sides of the freely rotating wheel.
  • the object of the invention is to realize a mechanism and a device for converting a reciprocating movement into a rotational movement and vice versa, such that at least one of the above drawbacks or complications is obviated or reduced.
  • the mechanism according to the invention is characterised in that the second and third wheels are also positively coupled by further means; a reliable engagement of all wheels is achieved, whereby the position of the centres of the wheels is kept at all times and disengagement of the second and third wheels from the first wheel is obviated.
  • the mechanism according to the invention is further characterised in that the at least one wheel, which is provided with means for a rotatable connection with a rectilinear
  • reciprocating member is not provided with means for a rotatable connection at the axis through its centre i.e. not provided at this location with any further bearing or any further shaft for a rotatable connection.
  • connection of the reciprocating rod to the wheel can not be hindered anymore by any means for a rotatable connection at the axis through the centre of the wheel.
  • the connecting rod can advantageously be connected on both sides of the wheel.
  • the overall width of the wheel is kept to a minimum and the shaft for the rotatable connection at the excentrical axis can be kept short.
  • the mechanism according to the invention is characterised in that at least two wheels are coupled by means of magnetism, so that the wheels can not disengage from each other.
  • magnetism is used in order to keep the wheels engaged e.g. the wheels could be magnetised so that they attract each other.
  • electro magnetism can be used e.g. electric engines could be arranged to keep the motion of the second and third wheels synchronised at all times, so that these wheels, with the first wheel in between, are kept coupled at all times.
  • rectilinear reciprocating members Preferably, several means for rotatable connection with rectilinear reciprocating members are arranged such that at least two means follow perpendicular rectilinear reciprocating movements. With this arrangement balancing of the mechanism connected to reciprocating members becomes very easy.
  • the further means can be formed by centrical and/or excentrical gearwheels or ring gears.
  • a chain, a toothed belt, hypoid gear wheels or any other transmission using positive engagement (different from frictional engagement) can be used.
  • a simple rod e.g. with holes at its ends rotateably and positively connecting to shaft stubs on e.g. the second and third wheels can be thought of.
  • the wheels have a toothing which can be helical and preferably is a symmetrical helical toothing, e.g. a fish-bone toothing.
  • the centres of the wheels stay arranged on a straight line during motion.
  • this arrangement embodiments can have a relatively small height.
  • the mechanism can be used in all kind of devices.
  • It can for example be used in a device like an engine, a pump, a compressor or combinations thereof, whereby the rotational axis of the first wheel or both rotational axis of the second and third wheels are connected to at least one piston, possibly via a connecting rod, whereby preferably the connecting rod is fixedly mounted to or integral with the at least one piston, whereby the at least one pistons is arranged in at least one cylinder.
  • the pistons do not need to be hingely connected, a complicated hinge connection as used in conventional engines between connecting rod and piston can be obviated.
  • the piston(s) but also the connecting rods do make a pure rectilinear reciprocating movement. Vibrations causing noise and loss of power are herewith strongly reduced or even obviated.
  • the connecting rod comprises two open grooves perpendicular to each, the first groove for allowing a shaft to pass through and the second groove for allowing a gear wheel, perpendicularly arranged to the shaft, to pass through.
  • the connecting rod has a cylindrical shape whereby the rod can be hollow.
  • the connecting rod can be a (hollow) rod with a rectangular cross section. With such shapes and especially when the rods are made of one piece, the connecting rods can be very rigid. These rods are advantageously used when flat constructions are required. Symmetrical connection of these rods on both sides of the at least one wheel or first wheel leads to a proper force transmission between the connecting rod and wheels.
  • the device comprises means for cooling and/or lubrication, whereby in particular the reciprocating parts comprised of the connecting rod and/or the piston have a channel for cooling and/or lubrication purposes.
  • the compression ratio is adjustable by varying the position of the rotational axis (and thus the bearings) of the second and third wheels in the chassis of the device (or of the axis of the first wheel in the chassis, in case this axis has a fixed bearing) with respect to the position of for example the cylinders.
  • the compression ratio is adjustable by varying the distance between the rotational axis of the first wheel and the side of the at least one piston facing away from the first wheel or the distance between the rotational axis of the second and third wheel and the side of the at least one piston facing away from these wheels. This can be realized relatively easily, as the reciprocating movement of the connecting rod and piston is purely rectilinear.
  • the second and third wheels are mounted on straight shafts, whereby preferably along their length several second and third wheels are arranged with a different orientation with respect to each other.
  • this construction it is possible to combine several mechanisms having simple straight shafts and to fabricate embodiments in which vibrations of the mechanisms are balanced or reduced.

  • symmetrical helical teeth can be used.
  • the helical teeth help to reduce noise.
  • no side forces are introduced by the teeth on the wheels during rotation.
  • simple straight shafts can be used, so that complicated crankshafts are redundant. Also complicated connecting rods and hinge connections of the pistons are not needed. The production costs are therefore substantially reduced.
  • gear wheels When standard round gear wheels are used they can have a bearing or shaft arranged at excentrical rotational axis i.e. axis which do not coincide with the centres of the wheels. Such wheels can be easily balanced with respect to their rotational axis for example by adding extra mass on the wheel or by taking away mass at the side of the centre of the wheel.
  • Mechanisms and devices according to the invention are preferably balanced by mounting a counter balancing mass at a location on the at least one wheel which is provided with the means for rotatable connection with a rectilinear reciprocating member, whereby said location and the location of said means for rotatable connection with a rectilinear
  • reciprocating member are point symmetrical with respect to the centre of the at least one wheel and by providing at least one counter balancing mass with respect to at least one fixedly rotatable shaft, preferably on at least one excentrically mounted wheel on that shaft at the side opposite of the centre. In stead of or in addition to adding mass, mass can be taken away at the side of the centre of that at least one wheel.
  • the counter balancing mass on the at least one wheel is equal to the mass of the reciprocating mass, i.e the total mass of the conneting rod and the piston(s) when connected thereto.
  • a mass for balancing which is mounted or added to a wheel or a shaft can be a resultant mass constituted by e.g two masses arranged symmetrically on both sides of that wheel. Such masses could_be mounted on arms on both sides of the wheel, whereby the arms are perpendicularly mounted on the shafts on which the wheels are mounted.
