Definitions
- a device for a machine of displacement type a controlling gear arrangement for the device, and usage of the controlling gear arrangement
- the present invention relates to a device for a machine of displacement type, comprising: a) a non-rotatable housing which surrounds two mutually movable parts, b) a first part which with its outer circumference is controllably rotationally movable along inside wall of the housing, c) a second part which is controllably movable relative to inner circumferential face of the first part, and d) at least one inlet aperture and at least one outlet aperture associated with a wall of the housing.
- the invention relates, in a first aspect, to a controlling gear arrangement to cause continuous, mutually variable movement of a first part and a second part which are co-axial, and wherein said first and second parts are in operational co-operation with a main drive shaft, and in a second aspect relates to a controlling gear arrangement in operational cooperation with machine device to control two continuously rotating, mutually movable functional parts in the machine device, thereby causing continuous, mutually variable movement in the machine device of a first part and a second part which are co-axial, said first and second parts being in operational co-operation with a rotary main drive shaft which forms part of the controlling gear arrangement,
- the main drive shaft being in operational gearwheel coupling with a first rotary sub-drive shaft for the first part and with a second rotary sub-drive shaft for the second part, respectively, and
- the invention relates also to a usage of such a controlling gear arrangement.
- the known Wankel engine has only one rotor which rotates eccentrically in a stationary enclosing housing. In its first embodiments it was structured in such a way that what is the housing, in to-days well-known version, rotated about its own axis, implying that this first variant of the Wankel engine in reality appeared as a two-rotors engine.
- Wankel engine has not been a great commercial success, despite its capability of exhibiting high revolutions per time unit range and almost a vibration-less operation, small structural size and low weight.
- This is caused by substantial disadvantages such as relatively high manufacturing costs due to requirements related to fine polishing and coating of movement path of the inner circumference of the stator, significant sealing problems between stator and rotor, in particular towards the periphery.
- This is due to these sealing faces becoming extremely narrow, almost like a stripe, and where the angle of abutment is noticeably changed during rotation.
- the invention has as an object to find a solution to the challenges and known problems related to both sealing and surface ratios during normal operation for devices of types mentioned in the introduction, such as e.g. combustion engines, as it is according to the invention intended to provide a machine which exhibits many of the advantages of a rotary machine, such as having compact and light-weight structure, being vibration-less as regard mass forces, and which exhibits a mechanically simple structure with a minimum of movable parts, simultaneously with selection of required compression ratio being present.
- the initially mentioned machine is characterized in: e) that the two mutually movable parts have co-axial axes of rotation, f) that the first part internally has at least two radially, inwardly directed wings with arranged mutual angular distance along the curved inside wall of the part between the wings, g) that the second part has a hub which has at least two radially, outwardly directed wings with mutual angular distance, h) that portion of the hub between the wings of the second part is in slidable or adjacent contact with a curved, free end portion of the wings on the first part, i) that a curved, free end portion of each wing on the other part is in slidable or adjacent contact with the curved inside wall on the first part which is located between respective ones of two neighbouring of said wings on the first part, j) that the first part and the second part are both continuously rotatably movable, but with mutually variable movement, the wings of the second part being movable between respective neighbouring wings on the first
- the rotary main drive shaft co-acting with the controlling gear arrangement is operational gearwheel coupling with a first, rotary sub-drive shaft for the first part and with a second, rotary sub-drive shaft for the second part, respectively, cooperating, elliptical gearwheels being incorporated in the respective gearwheel coupling.
- the main drive shaft and said first and second sub-drive shafts are co-axial.
- said controlling gear arrangement mentioned in the introduction is characterised, according to the invention, in that the rotary main drive shaft, which forms part of the controlling gear arrangement, is in operational gearwheel coupling with a first, rotary sub-drive shaft for the first part and with a second, rotary sub-drive shaft for the second part, respectively, co-operative elliptical gearwheels being included in the respective gearwheel coupling, and wherein the main drive shaft and said first and second sub-drive shafts are co-axial.
- the arrangement is characterised in:
- the main drive shaft and said first and second sub-drive shafts being co-axial, - at least one first co-axial set of a rotary, elliptical gearwheel and a rotary, circular gearwheel which are fixedly interconnected with a first mutual axial distance, a rotation axis of the gearwheels being parallel to a rotation axis of the main drive shaft, the elliptical gear wheel of the first set forming gearwheel engagement with the elliptical gearwheel which is rigidly attached on the main drive shaft, and the circular gearwheel of the first set forming gearwheel engagement with a circular gearwheel on a sub-drive shaft for the first part for rotation thereof, and
- the usage of the controlling gear arrangement is to control two continuously rotating, mutually movable functional parts of a machine device in order in an operation cycle of the machine device to develop successive displacement varying suction-, compression- and ejection chambers in the machine device when it is a combustion engine or a compressor, or to successively develop varying displacement spaces in the machine device when it is a pump.

- variable chambers formed by the rotation of the inner rotor 101 and the outer rotor 102 are limited in axial direction by said front cover 104 (alternatively the front cover 105 or 106) and a rear cover 103, as shown on Figs.2, 8, 9, 11 and 12.
- the rear cover 103 is fixedly bolted to the circumference of the outer rotor, as will be further explained in connection with Fig.3b.
- Fig. 1 there is shown an embodiment of the device, according to the invention, configured for engine function.
- a housing 107 having a circular wall 108, a first end wall 109 and a second end wall 104 formed by the front cover 104 (front cover 105 or 106 if compressor function or pump function, respectively).

- the end wall or the cover 104 (alternatively the cover 105 or 106 which also can form an end wall) is preferably attached to the wall 108 using a plurality of attachment bolts 110, such as shown on Figs. 1 and 2.
- a housing 111 for the controlling gear arrangement coupling 112 for any test bench brake, toothed disc 113 for ignition indicator related to an ignition device 114, e.g. a spark plug, which can be screwed into the end wall 104.
- an ignition device 114 e.g. a spark plug
- a flywheel 115 which is attachable onto a main drive shaft 116 (see inter alia Fig. 2) in a manner known per se.
- the flywheel is therefore for sake of simplicity not shown on any of the other drawing figures.
- the coupling 112 and the disc 113 can suitably also be attached onto the shaft 116 or be attached thereto via the flywheel 115.
- the housings 107 and 111 are each provided with machine suspensions 117, 118, respectively.
- Corresponding machine suspensions may of course also be provided on diametrically opposite side of the respective housing 107, 111.
- the housings 107, 111 can e.g. consist of four interconnectable parts, but in a practical embodiment they can each consist of two halves, where one half of one housing is integrally cast with a half of the other housing, in such a way that the housings 107 and 111 consist of two integrally cast parts which may then be joined.
- the housing 107 i.e. the walls 108 and 109 thereof
- the housing 111 can be cast as only one item. This latter alternative is the currently preferred embodiment.
- an oil filling nozzle stub 119 for the controlling gear arrangement 201 which is located inside the housing, and which is to be described in detail later.
- an oil drain hole 120 At the bottom of the housing 111 there may be located an oil drain hole 120. Filling of oil may e.g. take place through injection of an oil mist, so that the interior of the housing is not filled completely with oil, and the oil can be drained out through the hole 120, be strained and be cooled before re-injection via the nozzle stub 119.
- FIG. 1 shown an injection nozzle 122 for fuel, an air suction manifold 123 having at the top thereof an attachment 124 for an air filter, a speed handle 125, and an exhaust manifold 126.
- Fig. 2 there is on the outside of the wall 104 a bracket 127 for attachment of the suction manifold 123 and the exhaust manifold 126 to respective suction aperture 128 and exhaust outlet aperture 129 from inside of the housing 107, i.e.. from the combustion chambers formed by means of the rotors 101 and 102 and the end walls 104, 109.
- the wall or cover 104 is integrally connected with a protruding wall portion in the form of a front bushing or front cover 130.
- the wall 104 surrounds a front shaft 131 for the outer rotor 102, and the front bushing 130 surrounds and clamps a roller bearing 132 for the front shaft 131 of the outer rotor 102.
- the front bushing 130 surrounds a shaft 133 for the inner rotor 101.
- a compensator 134 for mass inertia is attached by means of bolts 135 to the shaft 133 of the inner rotor.
- the front bushing 130 is terminated by a front end lid 136 which is attached to the front bushing 130 by means of bolts 137.
- An inlet 138 for cooling- and lubrication oil is suitably located in the front end lid 136.
- Fig.3 illustrates the outer rotor 102 in further detail. It has, in the shown embodiment, two radially, inwardly directed, diametrically located wings 137.
- the number of wings may possibly be increased, provided that the number of wings on the inner rotor is increased correspondingly. It may, however, require diametrical dimension increases of the machine.
- An alternative could instead be to axially connect in parallel multiple units of the housing 107 and the rotors 101, 102, or possibly increase their axial dimensions.
- the wings 139 are provided with a plurality of pressure drop grooves 140.
- the advantage of such pressure drop grooves is the avoidance of sealing springs to slide along a wall and which require well controlled lubrication, and which as regards wear is a serious problem related to inter alia an engine type like the Wankel engine.
- the rear cover 103 is attached to the rear side of the outer rotor 102 by using a large number of bolts 141 which are attached in corresponding attachment holes 142 (Fig. 3b) in the outer rotor 102.
- the outer rotor 102 is in addition provided with cooling creative recesses 143 from outer circumference and inwardly in the wings 139, so that the wings in reality will not be solid, but hollow.
- the recesses 143 co-operate with corresponding holes 144 (Fig.
- the inner rotor 101 is shown in further detail on Figs. 4 and 5. It has a hub 146 and diametrically located wings 147.
- the wings 147 are, as shown for the wings 139 of the outer rotor 102, also provided with pressure drop grooves 148 with technical advantages as discussed for the grooves 140.
- the hub 146 is advantageously also provided with an oil cooling space 149 for the inner rotor.

- a first part 102, which forms the outer rotor is with its outer circumference controllably rotation-movable along an inside wall face, i.e. the cover 104 of the housing.
- the other part, i.e. the inner rotor 101 is controllably movable relative to inner, curved circumferential face 150, i.e. wall portion, of the outer part 102.
- at least one inlet manifold 123 and at least one outlet manifold 126 are located on and associated with the wall 104, i.e. the front cover of the housing 107.
- the two mutually movable parts i.e. the rotors, 101 and 102
- have co-axial rotary axes i.e. the indicated axis 155.

- a first axial end of the two parts 101, 102 is in slidable or adjacent contact with the first cover, i.e. the front cover 104 with apertures 128 and 129, possibly via the bracket 127, for controlled communication with the chambers, the first cover 104 constituting said wall.
- a second end of the two rotors 101, 102 is covered by the second cover 103 which is attached to the outer rotor 102, as previously explained, and which is thereby rotary therewith. This implies thereby that the first rotor 101 becomes in slidable or adjacent contact with the second cover 103 when the rotor 101 rotates.
- Movements of the two mutually movable rotors 101, 102 are influenced by a controlling arrangement 201 which operationally includes the rotary main drive shaft 116 for the machine.

- the elliptical gearwheel 207 is located on the main drive shaft 116 and is common to all gearwheel couplings 202, 203; 202, 204 ; 202, 205; 202, 206.
- the gearwheels in the parts 203; 204; 205; 206 of the respective gearwheel couplings are installed rotatable on a respective shafts 212; 213; 214; 215, and these shafts are installed onto an attachment plate 216 which is fixedly bolted to the housing 111 via holes 217 in the plate 216 and attachment holes 219 in the housing 111. Short attachment bolts 218 can pass through the attachment holes 219 in the plate 216.
- Circular gearwheels 220; 221; 222; 223 are also included in the parts 203; 204 ; 205; 206.
- the gear wheels 220, 221 are in gearwheel engagement with a circular gearwheel 224 which constitutes connection to the shaft 167 for the outer rotor 102.
- the gear wheels 222, 223 are in gearwheel engagement with a circular gearwheel 225 which constitutes connection to the shaft 133 for the inner rotor 101.
- the set of gearwheels being included in the parts 203; 204 has been shown in more detail on Fig. 13, from which is seen that the elliptical gearwheel 208; 209 is axially separate from, but rigidly connected with the circular gearwheel 220; 221 by a distance dl.
- Bearings 226; 227 are arranged inside the elliptical gearwheel 208; 209 and on the circular gearwheel 220; 221 in order to arrange these to be rotatable on the shaft 212; 213.
- Bolts 228 rigidly interconnect the gearwheels 208, 220 and 209, 221 with an intermediate piece 229.
- the distance dl is somewhat larger than the thickness of the gearwheel 225, e.g. approximately 10-25% larger - even though this is only to consider as a non-limiting proposal.
- the distance dl is present in order that the gearwheels 210, 222 and 211, 223 in a reliable manner may form a respective gearwheel engagement with the gear wheels 223, 224.
- the set of gearwheels being included in the parts 205; 206 have been shown in more detail on Fig. 14, from which is seen that the elliptical gearwheel 210; 211 is axially separate from, but rigidly connected with the circular gearwheel 222; 223 by a distance d2, the distance d2 - in a non-limiting example - being e.g. 10-25% of dl.

- Bolts 232 rigidly interconnect the gearwheels 210, 222 and 211, 223 with an intermediate piece 233.
- the distance d2 enables the gearwheel 225 to pass unobstructed with its outer circumference in this d2 -dimensioned interspace.
- first pair of same parts 203, 204 and a second pair of same parts 205, 206 it will be appreciated that it will be possible to use only one of the parts of each pair, e.g. the parts 203 and 205. By using only one of the parts of each pair, this may yield a limitation to maximum transfer of momentum (torque) if strength specifications are not improved. In a practical, currently preferred embodiment, there is used pairs of parts 203, 204 and 205, 206 .
- composition of sets of gearwheels just shown and described is the currently preferred one.
- the power transfers are: 167 ⁇ 224C ⁇ 220C + 208E ⁇ 207E ⁇ 116 167 ⁇ 224C ⁇ 221C + 209E ⁇ 207E ⁇ 116 133 ⁇ 225C ⁇ 222C + 210E ⁇ 207E ⁇ 116 133 ⁇ 225C ⁇ 223C + 21 IE ⁇ 207E ⁇ 116
- the elliptical gearwheels in the gearwheel set parts 203, 204, 205 and 206 are preferably of the same configuration, and the circular gearwheels in the gear wheel set parts 203, 204, 205 and 206 have preferably the same configuration.
- the controlling gear arrangement 201 in its currently preferred embodiment, exhibits a continuous rotary movement which controls a mutually varying movement of the outer rotor and the inner rotor, the rotational pattern of the movements of these parts being a function of the ratio between the largest and smallest diameter of the elliptical gearwheels 208 - 211 and largest and smallest diameter of the elliptical gearwheel on the main drive shaft 116.
- controlling gear arrangement 201 it will correspondingly be the ratio between the largest and the smallest diameter on the elliptical gearwheels 220 - 225 which will be decisive for the co-operative rotational pattern of the outer rotor 102 and the inner rotor 101.
- the housing 111 is at a rear edge region 176 provided with a plurality of attachment holes 177 for bolts 178 for attachment of a rear cover 179 which covers the controlling gear arrangement 201.
- a bushing-like portion 180 which is integral with the cover 179,
- a roller bearing 181 is located between the drive shaft 116 and the inside of the portion 180.
- a thrust bearing 182 is located between the drive shaft 166 and the inside of the portion 180.
- the thrust bearing 182 is kept in place by means of a locking ring 183.
- the free end of the bushing like portion 180 is terminated by an end lid 184 which is attached by means of bolts 185 to the free end of the portion 180.
- the drive shaft 116 passes through the end lid 184 and a sim-ring 186 which thereat forms sealing between the drive shaft 116 and the end lid 184.
- the device may be configured as a combustion engine, and wherein one of the end walls of the housing 104 is provided with a suction gate 123 for air, exhaust gate 126 and ignition device, e.g. spark plug 114 and/ or injection nozzle 122 for the fuel, if diesel operation is an issue.
- a suction gate 123 for air exhaust gate 126 and ignition device, e.g. spark plug 114 and/ or injection nozzle 122 for the fuel, if diesel operation is an issue.
- the combustion engine can be configured for operation according to an Otto-process.
- the spark plug 114 or the nozzle 122 is located, radially viewed, on opposite side of the rotary axis 155 of the two rotors, relative to said suction- and exhaust gates 128, 129 which are associated with the respective manifolds 123, 126.
- one of the end walls 105 is provided with at least two fluid suction gates 172 and at least two fluid ejection gates 173.
- one of the end walls is provided with at least two fluid suction gates 174 and at least two fluid ejection gates 175.
- pairs of suction gates 172; 174 and ejection gates 173; 175 are neighbouring. Relative to the common rotary axis 155 of the two parts 101, 102, pairs of suction gates are located diametrically, and pairs of ejection ports are located diametrically.
- the rotational velocity of the drive shaft 116 will thus be equal to the mean value of that of the rotors.
- the rotors thus swing mutually about the steady rotation of the drive shaft: the pressure forces during combustion cause a larger momentum to occur from the wing on that rotor which moves faster than the other, and this momentum is transferred to the drive shaft.
- the rotors subsequent to each ignition at that position which for each chamber may correspond to upper dead-point of a piston engine
- change as regards to be the fastest they appear alternately corresponding to piston top and top cover.
- the device according to the invention has some features in common with a four-stroke piston engine, but is also remarkably different from such an engine.
- the machine has like piston engines a small combustion surface and relatively large sealing faces. Because the faces are so large and in addition do not touch each other, a labyrinth- and pressure trap sealing is possible, yielding that lubrication oil inside the chamber region advantageously can be omitted. Contrary to a four-stroke piston engine, each chamber performs suction, compression, expansion and ejection for each revolution. With four chambers as shown, the machine thus corresponds to - as regards cycles - an eight cylinder piston engine. With the invention, there is however required only one ignition device and no mechanically controlled valves.
- FIG. 16 it is now referred to Fig. 16 as regards what is happening with one chamber 159 of the four chambers 159 - 162.
- Fig. 16a represents an initial suction phase for fuel, e.g. mixture of petrol and air, related to the chamber 159, the chamber 159 being in a closed position just before suction is to start. A round spot indicates that chamber 159. The remaining three chambers 160 - 162 are in other parts of the cycle. In order to simplify the understanding we therefore follow only the chamber 159 through phases of suction, compression, ignition, combustion/ expansion, and ejection of exhaust gases.
- fuel e.g. mixture of petrol and air
- Fig. 16b represents an initial compression phase related to the chamber 159, the chamber 159 having completed suction through suction gate 128, and compression starts from the shown position, the suction gate being closed by the wing 147.
- Fig.16c represents a terminal compression phase related to the chamber 159, where the chamber 159 has much of its volume decreased and the fuel gas approaches the space at the ignition plug 114. If the engine is to operate as a diesel engine, there will be only air which is compressed and approaches an ignition device 114 in the form of an injection nozzle for controlled injection of diesel oil and subsequent spontaneous ignition and expansion of the mixture of diesel oil and air.
- Fig. 16d represents an ignition- and explosion phase related to the chamber 159. In this phase the ignition plug 114 is uncovered towards the chamber 159, and dependent on rotational velocity a certain pre-ignition takes place, early if the rotational velocity is high, and somewhat later of the rotational velocity is low.
- Fig 16e represents an expansion phase related to the chamber 159, i.e. illustrating the chamber 159 during fuel combustion and thereby expansion.
- Fig. 16f shows a blow-out phase related to the chamber 159, where the chamber 159 opens towards the exhaust outlet aperture or -gate 129 and in such a manner the combusted gases are ejected thereat.
- the inner rotor 101 is cooled by an oil passing through, entering via the inlet 138 on the front end lid 136 and dispersing in axial direction towards the interior of the housing 111, the oil on its way lubricating and cooling the bearings for the shafts of the rotors, and being drained out from the housing 111 via the outlet 120 together with lubrication oil which has entered the housing the nozzle stub 119.
- the machine according to the invention may use a turbo-charger almost similar to a piston engine in order to enhance the performance.
- the charger will in this case work under excellent dynamic conditions as the turbine part will receive an almost uniform flow of exhaust gas.
- the machine according to the invention may operate free of oil internally between the rotors. This is of great advantage as regards friction and emissions of pollutions to the environment, and yields little or no consumption of oil or replacement of oil because it in reality is not being polluted by combustion products.
- Figs.17a and 17b are typically related to letting the machine function as a compressor, external power being delivered to the drive shaft 161.
- Fig. 17a represents a suction phase for fluid, e.g. air and/or gas, related to the chamber 160
- Fig. 17b represents an ejection phase of compressed fluid, e.g. air and/ or gas fluid, related to the chamber 160.
- Remaining chambers are present in other rotary phases, but the chambers 160 and 162 perform in reality simultaneously the same phases of compressor function, and correspondingly for the chambers 159 and 161.
- the machine performs four suctions and four ejections per revolutions, corresponding to a four-cylinders piston engine.
- Figs. 17a and 17b show, in the same manner as in Figs. 16a - 16f, that we, for a simple understanding of the operation follow a specific chamber, here the chamber 160, marked with a black spot, but here with a simpler progress.
- the end cover 105 is used with diametrically positioned sets of two suction gates 172 and two ejection gates 173. These corresponding gates can, as indicated above, either be interconnected or operate separately.
- the machine can be used to mix two different gases with separate suction inflow via the gates 172 and with common ejection via gates 173 which have a common outlet manifold, whereby two different gases having separate gates can be compressed, where the ratio between the gases can be controlled by choking the respective suction inflows.
- the suction- and ejection gates 172 and 173 are also possible to mix two different gases with separate suction inflow via the gates 172 and with common ejection via gates 173 which have a common outlet manifold, whereby two different gases having separate gates can be compressed, where the ratio between the gases can be controlled by choking the respective suction inflows.
- the cycle is here quite simple, as in Fig. 17a the gas or gases (possibly just air alone or gas and air) being sucked in through the gates 172, being compressed and ejected thereafter out through the gates 173, as shown in Fig. 17b.
- the geometrical ratio between the rotors i.e. the formed chambers
- the geometrical ratio between the rotors can be changed to almost zero at smallest volume in the chambers. This can be done by e.g. increasing the width of the rotor wings, or change the ratio between largest and smallest dimension on the controlling elliptical gearwheels in the controlling gear arrangement 201. The latter may provide greater volume passed through.
- Adapted compression rate is determined by size, shape and location of the ejection apertures 173.
- the compression ratio is not used as a term, but instead the displacement ratio which indicates how much of the cylinder gross volume is displaced.
- the portion not being displaced is denoted as "harmful space”.
- the displacement ratio in a compressor should be as high as possible in order to avoid harmful space to the extent possible. Due to this reason it may, as just mentioned, in the machine according to the present invention, be necessary also to change something on the configuration of the elliptical gearwheels in the controlling gear arrangement 201, in order to obtain largest displacement ratio possible.
- embodiment of the machine may be used as a gas powered engine.
- a corresponding situation like that just explained for Figs. 17a and 17b is present for the pump solution which is illustrated with reference to Fig. 18a and Fig. 18b.
- a pump is like the compressor as regards structure, but with the difference that the outlets are changed to have same size and shape as the inlets. This is because the displacement must take place out from the chambers from when they are at largest volume until the reach the smallest volume. As previously described it is only required to switch the front cover 104 to the embodiment of the cover 106 in order to use the invention in pump version.
- Figs. 18a and 18b clearly illustrate that there are great similarities to the compressor application as shown on Figs. 17a -17b.
- the significant differences are the shape and the size of the ejection gates 175, which are here shaped like the suction gates 174. This is due to liquid not being compressible in a way similar to that of air and/ or gas, whereby ejection must start as soon as a decreasing of the chambers commences. Otherwise, the functions are identical to the compressor function in Fig. 17, but here in the pump function, the mixture ratio is difficult to control and can therefore be locked to 1 : 1.
- the rotors 101 and 102 could possibly have had a larger number of wings, but in practice this will yield reduced displacement volume and increased surface exposed to heat, and as a combustion engine this will considerably increase the thermal losses, which therefore does not appear to yield any technical advantages when viewed in full. As a compressor a larger number of wings will on the contrary be desirable, as increased heat transfer during compression reduces the polytrophic index and thereby reduces the energy consumption.
- the controlling gear arrangement 201 may possibly be constructed using technical solutions other than those implying elliptical gearwheels.
- the almost same movement can be obtained using circular gearwheels instead of elliptical, but where the center of rotation of the gearwheels in such a case is located eccentrically in the gearwheel.
- This will, however, yield an extremely complex structure and is in practice hardly practical or economical to carry out.
- the solution which is shown and described is therefore the one which is currently preferred, although also the previously described technical equivalent can be envisaged.
- the machine can be made with multiple sets of rotors in axial direction, and also possibly have other fields of use than those described.
- the invention provides a machine structure which solves problematic issues related to both sealing and surface ratios during a phase of combustion, such as free choice of compression ratio, while at the same time yielding a compact and light-weight structure which is vibration-less as regards mass-forces, and which exhibits to a large extent technical simplicity as well as few movable parts.
- gearwheels are shown without teeth, but it will be appreciated that such teeth are present. Whether the teeth are parallel with the axis of rotation of the gearwheel, are inclined relative to the axis of rotation, or have a V-shape, is a matter of choice of structure.
- Inclined teeth provide a larger gripping face for inter-engagement of the teeth and yield less operational noise, similarly to teeth having V-shape.
