Description

This invention relates to instruments for automatically recording a path, pass. A moving object, for example, a bicycle, car, ship or airplane, using two friction discs, rotated at a speed proportional to the speed of the moving object, and used to rotate the friction rollers through appropriate gears that move one belt and the other a carriage with a food device in a direction perpendicular to the movement of the paper tape.

In the proposed device, in order to obtain on the tape a line with a rumba that corresponds to its slope from the axis of the device, two friction rollers, which are at a constant distance from each other, run along friction disks made in the form of the same the diameter of the gears mounted on the board, which can be moved manually or automatically using a rack with a disk divided into degrees or rumba.

In FIG. 1 - 4 depict the scheme of the device; FIG. 5 is a schematic side view of the device for automatically recording the path traveled by the moving object; FIG. b-view it from above.

(b4a)

Two interlocking teeth, G and 2 of the same diameter, are connected by friction with two spacing free rotating rollers 3 and 4 (Fig. 1-4), which control the movement of the feather, respectively, in axes x and y. The angular velocity and direction of movement of the 3 l 4 rollers depend on their position on the gears. With the change of such, the increment of all values from - | - maximum through O to maximum is obtained, therefore a squeaking feather, as representing the resultant of both increments, can continuously change its azimuth from 0 to 360 ° depending on the position of the rollers on the gears.

Gears 1 2 receive movement from the leading parts (wheel, screw or propeller) always in one direction and proportional to the speed of rotation of those parts, and the speed and direction of rotation, frictionally associated with the gear rollers 3 4, controlling the movement of the pen (5 along the axis x, 4 along the axis y), depend on their position on the disks — gears. So, at the position in FIG. 1 roller 5, located on the edge of the teeth /, will rotate at maximum speed, and roller 4 located in the center of the teeth / will not rotate at all. Therefore, the pen will only move along the x axis and draw a line in the direction N. If you move the teeth / and 2, as indicated in FIG. 2, the roller 3 will become in the center and will not rotate at all, and the roller 4 will rotate at maximum speed. Therefore, the pen will only move along ocn-f-J in the direction of W. At the positions intermediate between L / and R, an inclination angle is obtained corresponding to the removal of roller 5 from the edge of the rack, and its center roller. In particular, when they are located at equal distances from the edges, the angular velocity of rotation of the rollers 3 and 4 will be the same, the movement of the pen on the axes x and y will be equal, and the resulting line will give a straight line with a slope of 45 °, which feather traced. Moving the teeth f and 2 further, to the position on fig 3, the roller 3 is on the edge of the gear and rotates with maximum speed, but already in the opposite direction against the position in FIG. 1, and the roller 4 is in the center of the rack 2 with zero movement. Consequently, the pen will draw a line along the axis-l: along the direction S. Finally, in the leftmost position of the gears / and 2 (Fig. 4) roller 3 will be in the center and will not move, and roller 4 on the edge of the rack 2 will give the maximum movement, but in the opposite direction against FIG. 2. Therefore, the pen will be drawn along the y-axis in the direction 0. Thus, a change in the position of the friction rollers on the gears will give a change in the speed of movement of the pen as the X axis, and along the y axis, and the resultant of these movements will always be proportional to the speed of rotation of the gears 7 and 2, i.e. the leading parts; It will give any desired azi with a sudden change in the position of the friction rollers on the gears, and with a smooth change in this position, the pen will write a curve that corresponds exactly to the turns of the steering wheel of the car, the ship, the airplane, i.e., give their way. Connected to a rigid or flexible conveyance 27 with leading parts 28 tOcb. 5 bears a clutch 6 with annular protrusions and a peg 7 entering into a longitudinal groove on the axis 5, allowing the clutch to move along the axis, rotating with it. A conical gear 8 is attached to the coupling, transmitting through the second conical gear the friction disks, in the form of gears 7 and 2 interlocked with each other, mounted on a board 9 moving parallel to axis 5 with a spur JO in the gap between the annular projections of coupling 6 , moving the entire system along the axis 5 when the board 9 is moved manually or automatically using cremalisers 77 (FIG. b), fastened with a disk 29 divided into degrees and rumba. Perpendicular to the plane of the gears 7 and 2 there are two rotating in the centers of the friction rollers 5 and with rubber rims, both to increase the friction of the teeth 7, 2, and to paralyze vibrations when the propeller rotates on the airplane. Roller 3 bears a worm to 72, rotating a notched 72, impaled on an axis with a cylinder 75, covered with rubber, rubbing on a roll with paper tape, rewinding from the friction of cylinder 75 from coil 14 to coil 75. The axes of coils move in racks 76 and 76, and the paper tape thrown over the rollers 77 is pressed all the time by the influence of the light springs 8 on the rubber of the cylinder 75, why this paper is always unrolled and reeled onto the spools automatically with CHOpocTbKi movement of the circumference of the rubber cylinder. Thus, the roller 5 controls the rotation of the cylinder 75, thereby causing the paper tape (map) to move at a speed equal to the movement of the cylinder 75, i.e., it gives a movement along the axis - {-l ;. The roller 4, located at a constant distance from the roller 5. equal to the radius of the discs, rotates freely on its axis and carries a grooved pulley 7 I used to transmit rotation of the flexible thrust 20 to the upper pulley 27 mounted on the screw 22. The carriage goes along the screw the form of a sleeve 25 with a process that terminates in a feather 24 on the one hand,

on the other hand, the peg 25 enters the threading of the screw under the influence of the spring enclosed in the holder 26,

When the pulley 2 / rotation is rotated, the feather sleeve 23 moves along the screw 22 until the spindle 25 enters the thread of the screw. If the pin is pulled out by the head, then the pen can be freely moved to the desired point along the screw 22, i.e. along the axis - | - y.

According to the above, the device operates as follows. The movement of the leading parts (for example, a small propeller on the wing of an airplane) is transmitted by a rigid or flexible transmission 27 of axis 5. From rotating it and bevel gears 8, the teeth 3 and 2 begin to rotate. Then the roller 3 starts moving and using 72 the screw makes it rotate axle with cylinder J3. The coils J4, 15 pressed against it with a tape begin to rotate in one direction or another, which is why pen 2 draws a straight line along the paper (card). If the roller 4 is not above the center of the serrated teeth /, but outside of it, then it also begins to rotate with a certain speed, transmitting the rotation to the pulleys 19 and 21, and through them to the screw 22 moving the carriage coupling 23 with the feather 24.

 as the paper ribbon and the feather itself move simultaneously under the pen, both movements result in a certain line, the slope of which (azimuth, rhumb) depends on the speed and direction of rotation of the rollers 3 and 4 relative to each other, t, that is, on their positions on the gears 7 and 2.

Their position can be changed by rotating Cremal 77, moving the board 9 with the whole system of gears and fastened to a disk 29 divided by degrees or rumba.

By becoming manually or automatically against the index 30, the 2P disc division corresponding to the reading of the compass, we get on the instrument tape a line with a rumbah corresponding to its inclination from the instrument axis.
