Definitions
- the invention relates to a device and a method for generating a directed force from a rotary movement.
- a body If a body is set into a rotational movement, it is affected, among other things, by the centrifugal force, which, however, is not a directional force component, but rather acts radially outward from the axis of rotation.
- a directed force on the axis of the rotating body cannot be obtained with a rotating body whose mass distribution is rotationally symmetrical to the axis of rotation.
- the rotating body If the rotating body has a mass distribution that is eccentric with respect to the axis of rotation, an oscillation occurs. This is due to the fact that an increased centrifugal force occurs in the area of the additionally present mass on the rotating body and the vector of the centrifugal force rotates in a fixed connection with the mass and therefore acts on the axis of the rotating body in all directions, but not simultaneously. This generates an oscillation, as can be determined, for example, in the case of vehicle wheels with an imbalance, this oscillation not being able to be used as a targeted force.
- a directed vector of the centrifugal force ie a centrifugal force with a defined, essentially constant direction of force, has not previously been used in technology. Presentation of the invention
- the invention has for its object to provide a device and a method by means of which a directed force can be generated from a rotational movement of a mass body.
- the object of the invention is generated by a device with the features of claim 1 or claim 3 and a method with the features of claim 10.
- the invention is based on the idea of providing a positively rotatable swing body with an eccentric mass distribution with respect to the axis of rotation and converting the unbalance that can be generated by the eccentric mass distribution into a directional force.
- the transmission device comprises a pendulum which is pivotally attached to a support frame and on which the swing body is rotatably arranged, the pendulum initially absorbing energy during the rotation of the swing body and after it against the stop on Support frame is encountered, this transfers to the support frame.
- the flywheel body comprises a rotationally symmetrical base plate with a mass distribution which is essentially rotationally symmetrical with respect to the axis of rotation, and an unbalance body which is mounted eccentrically on the base plate.
- a flywheel with a mass eccentricity which is arranged stationary with respect to the flywheel can be produced in a very simple manner.
- the flywheel is preferably coupled to the output shaft of an electric motor.
- the use of an electric motor is appropriate since electric motors have a relatively high degree of efficiency and the overall efficiency of the device for generating a directional force is therefore higher than when using another drive means with poorer use of the energy used.
- the device further comprises a cam disk, which is fixed to the flow channel in a rotationally rigid manner, and cam rods, which are connected to the closable liquid outlet openings.
- a cam disk which is fixed to the flow channel in a rotationally rigid manner
- cam rods which are connected to the closable liquid outlet openings.
- the angular range on the circulation path of the flywheel, within which the liquid outlet openings are in a closed position is less than 15 ° and the angular range is preferably 12 °. So that the unidirectional vector of the centrifugal force is only formed in one direction and in one sense, it must be achieved that the mass not in equilibrium acts only a small distance over the entire circumference of the orbit and at a different point not far away , which is ideally at an angular distance of 12 °, disappears.
- the device further comprises a liquid delivery device, the outlet of which is in liquid communication with the flow channel.
- a liquid delivery device By providing a liquid connection, a continuously operating device can be created, in which the liquid emerging from the liquid outlet openings of the cavities is collected and fed back to the flow channel along the axis of rotation of the flywheel by a liquid delivery device.
- the liquid delivery device delivers liquid with a high density, preferably mercury.
- a high density liquid is advantageous because the greater the mass of the rotating body, the greater the centrifugal force. If a liquid with a very high specific weight is now used, a very high eccentricity can be achieved the mass distribution and thus generate a very large, obtainable force.
- the cavities in or on the flywheel can be filled with liquid very quickly at a very high rotational frequency of the flywheel, since the liquid expands very rapidly into the cavities which are under ambient pressure.
- FIG. 4 is a top view of the swing body shown in FIG. 3 with the associated opening and
- the device generally designated 10 consists essentially of a support frame 12, which can be made of any material. Also the 1A to 1E, the geometry of the supporting frame is only of minor importance, which is why in the present example an arbitrary, schematic representation was chosen.
- a pendulum 14 is pivotally attached to the support frame 12. For this purpose, there is preferably a suitable bore in the support frame through which a pivot pin 16 can be inserted or driven, which in turn creates a rotatable connection between the support frame 12 and the pendulum 14.
- connection between the support frame and the pendulum is to be carried out in a particularly low-friction manner, slide or ball bearing connections, as are known and customary in the art, can of course be used.
- the pendulum can be fastened between two forked carriers of the support frame or the pendulum can have a forked shaft that encloses a carrier of the support frame.
- a swing body 18 is rotatably attached to the pendulum 14.
- the flywheel consists of a flywheel 20 and an eccentric mass 22 which is fixedly attached to the flywheel.
- the swing body 18 shown in FIGS. 1A to 1E is, of course, only one possibility of many to arrive at a rotatable body with an eccentric, but stationary mass distribution relative to the swing body.
- the flywheel could also consist of a flywheel 20 without eccentric mass 22, the flywheel not being circular, as shown in FIGS. 1A to 1E, but having a non-constant outer radius.
- the swing body 18 is, as already explained above, rotatably attached to the pendulum 14, but non-rotatably connected to a drive unit, not shown.
- the illustrated shaft 24 could, for example, be the output shaft of an electric motor that is behind the flywheel 18 in the viewing direction of FIGS. 1A to 1E and is arranged stationary relative to the pendulum 14 and its output shaft 24 sets the swing body 18 in a rotational movement.
- the electric motor is fed by an energy supply 26 which is shown schematically in FIGS. 1A to 1E.
- the device 10 has a stop 28 which is fastened to the support frame 12 and against which the pendulum 14 can abut.
- the contact point between the stop 28 and the pendulum 14 with respect to the pivot pin 16 is arranged opposite to the swing body 18, however, the stop can also be provided in the immediate vicinity of the swing body 18, as long as the operation of the storage pendulum described below ensures is.
- the mode of operation of the storage pendulum results from the sequence of FIGS. 1A to 1E.
- the motor not shown, drives the flywheel 18 in the direction of arrow A, the pendulum being deflected relative to the position shown in FIG. 1E due to the imbalance or centrifugal force generated by the eccentric mass distribution of the flywheel, as with the direction of the bearing B is shown in Fig. 1A.
- the storage pendulum In the position shown in FIG. 1B, the storage pendulum has reached the state of its maximum force absorption, which is characterized by the greatest possible inclination of the pendulum 14 from the vertical.
- an intermittently acting, directed force F is generated by the continuous drive of the flywheel 18, whereby use is made of the possibility of taking up energy with the pendulum during the various operating phases in continuous operation, which energy is released upon contact with the rubber buffer.
- FIG. 2 shows a schematic sectional view of a device 30, in which an imbalance that is stationary within the device 30 is generated using a liquid.
- the device 30 is surrounded by a housing 32 which encloses the device in a liquid-tight and gas-tight manner.
- a liquid collecting container 34 is formed within the housing 32 and contains a liquid which is preferably of a high specific Has weight. Therefore, liquids such as mercury are also considered.
- a suction pipe 36 is immersed in the liquid in the liquid collecting container 34 and is connected to a pump 38 to which the liquid conveyed by the suction pipe 36 is transported. The pump compresses the liquid to an elevated pressure, preferably a high pressure of approximately 100 bar.
- the outlet pipe 40 from the pump 38 is connected in a liquid-tight manner to a flow channel 42 which represents the hub of the swing body 44.
- the flywheel 44 is non-rotatably connected to the output shaft of a drive device 46 with adjustable speed, wherein the drive device 46 can be, for example, an electric motor with a high degree of efficiency.
- the components on the flywheel 44 which are also shown in FIG. 2 will be explained in more detail with reference to FIGS. 3 and 4.
- the drive device 46 can be used to drive the pump 38, even with the interposition of a suitable gear.
- the flywheel 44 is connected in a rotationally rigid manner to the output shaft 48 of the drive device 46, the output shaft of the drive device or the drive shaft of the flywheel body being mounted 50 in the housing 32.
- the cylindrical wall 52 surrounding the flow channel 42 is provided in the area of the swing body 44 with a liquid passage opening 54, which is circular in the example shown, but can also have different geometries.
- Inside the swing body 44 there are cylindrical cavities 56 which run in the radial direction in the swing body 44 and at their radially outer end through a valve device 58 are lockable.
- the valve device is actuated with the aid of an adjusting lever 60, which is connected to a cam rod 62 by an articulated connection 64.
- cam rods 62 are held by suitable guides 66, which are fixedly connected to the flywheel 44, and move with their radially inward-facing ends 68 on a cam disk 70.
- suitable guides 66 which are fixedly connected to the flywheel 44, and move with their radially inward-facing ends 68 on a cam disk 70.
- a groove-shaped cam guide can also be provided, so that the cam bars force that the cam rods work safely even with high, acting centrifugal forces.
- the cam rods 62 shown at the top and bottom of the drawing plane are in different positions due to the non-rotationally symmetrical geometry of the cam disk 70.
- the cam disk 70 is connected in a rotationally rigid manner to an adjusting disk 72 which, as shown in FIG. 2, is coupled via a chain transmission 74 to an adjusting mechanism 76 which is fixed to the housing and which in turn can be actuated by a servomotor 78 outside the housing.
- a second adjusting disk 80 is connected in a rotationally rigid manner to the wall 52 of the flow channel 42 and, as shown in FIG.
- the second adjusting disk 80 serves to bring the wall 52 of the flow channel 42 into a desired radial position.
- the servomotors 78 and 86 have the task of bringing the cam disk 70 and the cylindrical wall 52 of the flow channel 42 into a desired angular position in order to adjust the direction of the force generated.
- the servomotor 79 also shown in FIG. 2, serves to set the speed of the motor.
- FIG. 4 is a top view of the flywheel 44 with the cylindrical cavities 56 and the cam rods 62 ⁇
- the stored energy in the pendulum is transmitted at the position shown in Fig. 1D.
- the energy stored in the pendulum in FIG. 1B
- the on that Returning force acting on the pendulum was measured with a dynamometer, the measurement being about 7.2 N without taking into account the support of the centrifugal force when returning the pendulum.
- the total force exerted by the storage pendulum therefore has the following value:
- E consumed 6 e a R ig h rc h ENS
- the energy required to increase the mercury from 1 to 2 is:
- E 1 is the kinetic energy of the entire system (disc with the tubes) without the mercury. It follows
- ⁇ Cl I ⁇ ' E 2 denotes the kinetic energy of the rotational movement taking into account the increase in mercury up to
- the areas of application of the generated force can be used both in the use of presses instead of hydraulic presses, but also in the generation of impulses in any type of load, be it in industry, self-propelled, in land, sea and air transportation .
- the force can be used as a piston for self-propelling for projectiles or the transport of solid, liquid or gaseous substances, as well as for the generation of pressure or negative pressure in hydraulic media, liquids or pneumatic media.
- Another area of application is lifting equipment for loads such as cranes. Since the force generated with the device according to the invention can also be generated in the absence of gravitational fields, use in space vehicles is particularly important.
