Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for converting centrifugal force into a linear force and therefore into a linear motion.

Various attempts have been made to obtain benefits by converting strong and easily generated centrifugal forces into linear forces. For example, these devices rotated a mass member to move its center of gravity relative to an axis of rotation. The result was a greater centrifugal force as the mass moved than during the remainder of the rotation cycle. In short, the radial length of the arm was changed. As is well known, preserving angular motion tends to reduce the velocity of the moving mass accordingly. An example of a successful machine of this type was introduced in August 1972.
No. 3,683,707, issued on the 15th. Effective devices for converting centrifugal force into linear force for use in automobiles, railroad cars, ships, aircraft, and space planes are desirable and widely used in the transportation industry.

The invention achieves this objective by utilizing a first rotating arm that moves about an axis of rotation. A pair of balanced masses is the first
rotates at the end of this arm in a plane perpendicular to the plane of the arm. The second arm rotates in a direction opposite to the first arm about the same axis of rotation as the first rotating arm and moves in a plane parallel to the plane of rotation of the first arm. The first and second arms mechanically cooperate to allow one of the parallel weights to move from the first arm to the second arm. At a selected point in the rotational path of both arms, one of the masses moves to offset the centrifugal force produced by the first rotational arm. After both arms have rotated through 180° in the circular path, this one mass moves from the second arm to the first arm again. At this selected location there is a centrifugal force bias due to the arm having the mass moving in an additional 180 DEG arc compared to the semicircular motion of the prior art. In other words, the net result of an arm with a pair of masses is an imbalance of centrifugal forces in the circular path halves of both arms.

The resulting imbalance is transferred to a linear unidirectional force component by mounting both rotating arms on rails or friction wheel carriages.

Referring to the drawings, the entire apparatus is generally designated by the reference numeral 1.
It is shown as 0. FIG. 1 shows an apparatus 10 that includes a first arm 12 and a second arm 14 that rotate in opposite directions relative to each other about an axle 16 (FIGS. 1 and 2). Arms 12, 14

is secured to the shaft 16 using a flange 28 by suitable means such as welding.

Referring to FIG. 2, drive shaft 30 is rotated by energy obtained from any power source (not shown). Block portion 32 and bearings 34 support shaft 30 to permit smooth rotation of the shaft about its axis as is well known in the art. The shaft 30 includes a miter gear 36 at its end proximal to the shaft 16 which meshes with a bevel gear 38 integral with a bushing 40 which freely moves around a bearing surface 52 mounted circumferentially on the shaft 16. Slip. Flanges 42 and 44 are secured to arm 14 so that rotation of bushing 40 causes arm 14 to rotate about the axis of shaft 16. The upper end of the bushing 40 connects to a bevel gear 46 that meshes with a miter gear 48. A stud 50 fixedly engages the shaft 16 and a bearing 54 surrounds the stud 50. Thus, miter gear 48 rotates about the fixed axis of stud 50. C-shaped ring 5

As shaft 88 rotates rods 110, 112 (having the same length) and masses 114, 116, the masses and weights balance each other. hub 104
As will be described in detail later, when one of the weights moves, it performs the function of damping vibrations. Arm 14 has a U-shaped groove 188 between partitions 128, 129 with a width equal to the width of mass 114 or 116. Openings 120, 122 are connected to the fingers (not shown) of mass 114 or to mass 1 depending on which mass is to be moved from arm 12 to arm 14.
Accommodates 16 fingers (only finger 130 is shown by way of example).

A pin 132 rides on a cam follower 134 that moves a flexible circular cam on a track 136.
Cam track 136 is connected to blocks 138, 140, 14
It is supported by a plurality of blocks including 2,144. Block 140 is handle structure 14
8 has an inclined surface to which it is attached, so that the circular track 136 can be lowered to the same height in block 40 as it is in block 138.

The mechanisms involved in the actual movement of either mass 114 or 116 will now be described in detail with reference to FIGS. 4-10. As an example, assume that the mass 116 shown in shading in FIG. 2 is used as the mass to be moved. FIG. 4, which shows the mechanism in the activated position, shows a plate 150 that fits into an arcuate groove 152.
A rod 112 is shown having a . Rod 112 is plate 1

A mass body 116 can be held while rotating around 04. As shown in FIG. 5, pin 132 rises partially within V-shaped groove 154 when raised by track 136. As shown in FIG.

The mass 116 has two equal parts 156, 15

Pin 132 is inserted into slot 16 to prevent rotation of the pin in a vertical plane during movement of mass 116.
8 and a key 170 provided on the arm 14. Masses 114 include the same mechanisms as for masses 116 to move from arm to arm 14, and these masses are freely interchangeable in performing the movement function to evenly distribute wear, tear, etc.

When actuated, the device 10 moves between the masses 114 and 11.
The two counter-rotating arms 12, 14 are synchronized so that they are vertically aligned in two positions within a rotation cycle of the arms 6 towards or away from the first arm 12. As previously mentioned, the mass 116 was arbitrarily selected, but any suitable scale can be used with the mass 114 in the movement mechanism described above.

Power from the power source drives drive shaft 30, which in turn rotates miter gear 36 and bevel gear 38. An arm 14 fixed to the bushing 40 rotates in a plane substantially perpendicular to the axis of the drive shaft 30. Bevel gear 46 turns miter gear 48 which turns bevel gear 60. Bevel gear 6
Arm 12 attached to flange 62 integrated with 0
The arms 12 and 14, which are lined up in a plane parallel to the path of the arm 14 in a direction opposite to the direction of rotation of the arm 14 at the "movement point" shown in FIG. 1, are vertically arranged and rotated via a gear mechanism. . Arm 12
As it rotates in a horizontal plane, the miter gear 72 and the bevel gear 76 rotate the shaft 88 and the mass body 11
Turn 4,116. At the moving point shown in FIG. 2, the mass body 116
It fits between the partitions 128 and 129 of No. 4. At this point, mass 116 and the end of arm 14 do not move relative to each other. Immediately before this point, the pin 132 is moved upward as the track 136 rises to form portions 156, 15.
8 is expanded, so it enters the groove 154. Finger pieces, exemplified by finger piece 130, enter openings 120, 122 and pass through plate 15.
The rod 112 with the 0 attached rotates out of the arcuate groove 152. The mass 116 has therefore been moved onto the arm 14 (FIGS. 4 to 6).

The arm 12 continues to rotate 180 degrees with only the mass 114 to the "transfer point". The vibration motion generated in the arm 12 by the mass body 114 is transmitted to the mass body 114,
Preferably, the damping is equal to the combined weight of 116. Similarly, partition 128,
129 must have the same weight as the hub 104, therefore, the mass body 116 and the partitions 128, 12
The combined weight of 9 is the hub 104 and mass body 114.
equal to the combined weight of During portions of the cycle of arm 12, device 10 is equilibrated.

Referring to FIG. 3, the short shaft 92 is provided with a spring 124 so that the vibrational forces acting on the arm 12 of the mass 114 are damped in one direction and serve to smooth the movement of the arm 12 as it rotates. press against.

When the "travel point" is reached, the transport mechanism reverses (FIGS. 7 to 10). The position of track 134 causes pin 132 to descend from groove 154. Fingers, exemplified by finger 130, exit through openings 120,122. Plate 150 engages portions 158, 160 (FIG. 9) or mass 114 again engages mass 11.
6 on the rod 112.

The mechanical components of device 10 include shaft 30 to reduce the effects of air friction acting on the rotating arm.
and the handle structure 148 can be extended inside and sealed by applying a vacuum.

If arm 12 includes both masses 114 and 116, shaft 16 will experience a force along arm 12. This phenomenon occurs in particular in the counterclockwise direction between "transfer points" and "transfer points". This linear force can be divided into two force components, one in the direction of arrow 172 and the other horizontally oriented. The horizontal force, which is a biasing force, is absorbed by the rigidity of the track 18. Accordingly, device 10 moves along track 18 in the direction of arrow 172. It should be appreciated that shaft 16 may be provided with pairs of arms similar to arms 14 and 16 to provide a stable force in the direction of arrow 172. The device 10 alone is capable of generating pulsed forces during the movement of the arm 12 from one moving point to another. The moving mechanism is the handle structure, therefore block 4
It can be deenergized by pulling the lower part of 0. The upper and lower portions of block 40 slide over surface 46 and pull down arm track 136 so that pin 132 does not enter groove 154 and mass 116 does not move. Similarly, raising track 136 180 degrees from block 146 reverses the movement mechanism and thus
moves in the opposite direction to arrow 172. In other words, when track 136 is raised to actuate pin 132, block 140 brakes device 10 moving in the direction of arrow 172 or causes stationary device 10 to move in a direction opposite to arrow 172.

Device 10 can be used with other similar devices to eliminate the need for track 18 and the like. For reference, a device for canceling horizontal force was introduced in 1972.
No. 3,683,707, issued May 15th. In particular, in column 8, lines 9 to 38 of this patent specification, the Y-axis force is analyzed and
It is described that the axial force is eliminated.

By way of analogy, a set of devices similar to device 10 is preferred, with legs 174 having similar axes 16 such that similar arms 12 are positioned at the first device's point of movement and the second device's point of movement. can be combined by connecting them horizontally (see Figure 11 and Figure 1).
