Definitions
- the invention relates to a mechanical device for generating any number of linear movements from a power source according to the preamble of claim 1.
- Objects to be animated such as robots or automatic mechanical pianos, require a multitude of linear movements. These linear movements usually only have to be a few millimeters to several centimeters. The forces required are different. To enable such movements, a large number of power sources are installed nowadays, which can be controlled individually. Robots that are built according to this principle receive, for example, a large number of electric motors on the joints.
- the invention has for its object to generate any number of linear movements in principle from a single power source, wherein the speed of movement and the respective force can be different. Furthermore, the invention has for its object to provide a standard unit that can be manufactured and configured inexpensively.
- this object is achieved by a single rotating motor which is connected to an axis which in turn has a profile.
- a clutch disc with a central profile that matches the profile of the axle is placed on the axle.
- This clutch disc also forms a round axis for a second clutch disc, which thereby remains movable with respect to the motor axis. If the two clutch plates are pressed against each other, the movable clutch plate is set in motion.
- This movable clutch disc has a gear that is connected to a larger gear.
- the larger gear has a roller that receives a rope that is firmly connected to it. As a result, the rope is subsequently rolled up on this roller and thus the rope is pulled.
- the Clutch disks, the gears and the rope are preinstalled as an assembly on a mechanical support and placed on the axis for a desired movement. Depending on the length of the axis and the number of movements required, such modules can be plugged onto the axis.
- Each assembly has a device for pressing the clutch discs.
- an electromagnet can be used for this.
- the diameters of the individual gears can be varied for different forces and speeds of movement.
- a counterforce is usually required for every force.
- the large gearwheel which is also connected to the rope pulley, can still have a parking brake. It is advantageous if the respective connections of the electromagnets reach an electronic control unit, so that the selection of an assembly and the pressure force there are made via electronic signals. This enables a computer to control all movements.
- Fig 1 an exploded view
- Fig. 2 a sectional drawing
- Fig. 1 shows the arrangement with an electric motor (1), the outer part of the shaft (4) is square.
- the clutch disc (2) has a centered opening that matches the square profile of the axis (4). This causes the shaft (4) to rotate it.
- the clutch disc (2) has a round outer axis on which the clutch disc (3) is attached. As a result, the clutch disc (3) initially remains in rest position without pressure on the clutch disc (2) when the shaft (4) rotates.
- the clutch disc (3) is set in rotation and drives the larger gear (5) via a small gear.
- This gear wheel (5) also has a rope pulley, so that when rope (5) rotates, a rope attached to it produces a linear movement.
- FIG. 2 shows how the individual parts from FIG. 1 can be assembled into an assembly. This makes it possible for such an assembly to be plugged onto the shaft (4) for each linear movement required.
- the clutch discs (2) and (3) and the large gearwheel with the rope pulley are arranged between two plates (6).
- the two clutch discs (2) and (3) are mechanically connected by their pressure by the two electromagnets (7), so that the previously described movement of the rope pulley is generated.
