Abstract

A device that produces a net force in a closed system comprising rotating rotor 1 and drive shaft 2 with attached bearing and plurality of races 3,4. A battery 6 and control board 7 ensure that power and control are achieved. In use the bearing 3 is attached to the rotor 1 and drive shaft 2 by either the inner race 3 or outer race 4, wherein the rotor can drive the drive shaft and inner race in a clockwise direction, causing the bearing to rotate clockwise and impart their momentum onto the outer race driven by the stator converting its counter-clockwise direction to a clockwise direction. The outer race is attached to the box 5 to enable it to travel in he same direction as the rotor creating an action-action, or reaction-reaction, and allowing a transfer of angular momentum.

Description

Device that produces a net force in a closed system.
The invention relates to a device that can produce a net force in a closed system, that can be utilised in the attitude control of satellites and spacecraft.
At present reaction wheels are used to control the attitude of satellites and other spacecraft by changing the speed of the wheel thus causing the satellite/ spacecraft to rotate to a desired position. Over time, reaction wheels may build up enough stored momentum to exceed the maximum speed of the wheel, called saturation, which will need to be cancelled, requiring fuel to be stored and then used in the process.
To overcome this problem the present invention proposes to use an action -action sequence or reaction -reaction sequence rather than the customary action -reaction sequence. This can be achieved by changing the transfer of angular momentum from the outer circumference of a bearing/ cog mechanism. To the inner circumference of a bearing/ cog mechanism. A bearing with a plurality of races would be used on a device that produces angular momentum.
The invention will also be of benefit to any system where counter rotation is a problem. Reducing or negating the torque reaction of a helicopters main rotor would be one example where an engine is used to rotate a drive shaft.
The invention will now be described solely by way of example and by reference to the accompanying drawings by which: Figure 1 shows an electric motor attached to a bearing. The bearing being attached to the closed box; Figure 2 shows a motor or engine with a through drive shaft with a 3-race bearing being used; Figure 3 shows the transfer of angular momentum inside a bearing; Figure 4 shows the transfer of angular momentum in a cog system.
In Figure 1 we see an electric motor with the rotor land the stator fitted with a drive shaft 2. The stator drive shaft 2 is attached to the inner race of the bearing 3. The outer race of the bearing 4 is attached to the sealed box 5. The motor is powered by the battery 6 and a control board 7 is also fitted.
The motor is switched on by the control board and the rotor begins to rotate clockwise. The stator drive shaft begins to rotate counter clockwise rotating the ball bearings in the bearing. The ball bearings will rotate clockwise but, since they will now interact with the inside of the outer race of the bearing they will impart their momentum in a clockwise direction so that the outer race will now rotate in the same direction as the rotor. Since the box is connected to the outer race of the bearing it too will rotate in the same direction as the rotor as we have an action -action transfer of angular momentum. The drive shafts can be reversed so that the rotor is connected to the bearing and the drive to the bearing can be either to the inner race or outer race of the bearing with either the inner race or outer race of the bearing not attached to the drive shaft attached to the box.
In figure 2 we have an engine or electric motor with a through drive shaft 8. The body of the engine or the stator of the electric motor is fixed 9 and one end of the drive shaft 8 is connected to the inner race 10 of a 3-race bearing 11. The outer race 12 is connected to the same object/ structure as the stator 9. As the rotor rotates clockwise the stator! engine body will try to rotate counter -clockwise but due to the 3-race bearing, angular momentum will be transferred from the outer ball bearing to the outer race so that the outer race will try to rotate in the same direction as the rotor. This will greatly reduce or negate the counter -rotation of the stator/ engine body thus stabilising the position of the object/ structure.
In Figure 3 we can see how the angular momentum is transferred through the bearing. The drive shaft 13 is rotating counter -clockwise and is connected to the inner race of the bearing 14, the ball bearings 15 rotate clockwise and then interact with the inner circumference of the outer race of the bearing 16 which turns in the same direction as the ball bearings and therefore the rotor.
In Figure 4 we have a cog system where the drive shaft 17 is splined so that as it rotates counter clockwise it rotates the two inner cogs 18 which rotate clockwise. The two inner cogs interact with the inner circumference of the outer cog 19 so turning the outer cog in the same direction as the two inner cogs 18. The same result as using a bearing will be achieved using the set up in Figure 1.
A battery is shown but any source of power can be used.
