Description

In the proposed device, which relates to instruments for determining and recording circumferential forces on a drive shaft, the rotation is communicated to the latter through a spring through the spring, the deflection of which is marked by a recording device, reinforced by a pulley and receiving movement from a special driver, pressed by a drive belt.

In FIG. 1 is a side view of the device; FIG. same in cross section; FIG. 3 is a front view of a detail of the device; FIG. 4 is the same side; FIG. 5- device variant, side view; FIG. 6 is the same in cross section.

The device consists of an idler driving pulley 1 with its spring 2 attached to the hub, a lever 3 fixed on the driven shaft 4 and a writing device 5 attached to the needle of the pulley 1.

When the pulley 1 rotates from the belt, the spring spring 2, pressing with its end on the lever 3, drives the shaft 4, is pressed, proportional to the overcoming force. The deviation of the end of the spring 2 is transmitted to the spindle 6 of the recording device 5. The spindle 6 is pivotally connected to the earrings 7.7, and when the spring 2 bends, it marks the deflection of the end of the spring 2 by the writing device 8 on the disk 9 the worm gear 11 gets going from

screw 12, which is in engagement with gear 11. In svov) the turn of hearts 12, located on a common shaft with gear 13, receives rotation from screw 14. The latter is mounted on a common shaft with a ratchet 15 receiving rotation through a doggie 16 from the ratchet 17. The rocking movement of the ratchet 17 in one direction occurs when the pulley 1 rotates from pressing the drive belt to the protrusion of the lead 18 of the ratchet 17 coming out of the rim of the pulley 1 and the reverse of the spring 19 that causes the leash 18, and therefore the ratchet 17 in; the first subliminal position. The latter occurs at a time when the protrusion of the leash 18 comes out of the belt pulley coverage arc. Thus, during one revolution, the ratchet 17 will make a swing and reverse swing and rotate the disk 9 at a certain angle, and the writing device 8 will mark the circumferential force per danyu turn of the pulley 1 at the appropriate scale.

A modification of the device (FIGS. 5 and 6) is as follows: a lever 21 is mounted on the sleeve of the idle pulley 20, and a lever 22 fitted with a closed buffer spring 23 attached to it by means of a hinge and attached to the drive shaft; pulley 20 to the shaft or, on the contrary, by an amount proportional to the transmitted force. A ha 24 deflects the spindle 6 of a recording device 5 (FIGS. 3 and 4) attached in this case to the lever 21.

The subject of the patent.

1. A device for determining the circumferential drive forces, and so on. shafts with a device for recording these efforts for each revolution, characterized by the use of a spring spring 2 fixed on the hub of the idler drive 1 in order to transmit the rotation, the drive shaft 4, the pressure of the spring 2 to the lever 3 fixed on the shaft 4

the spring 2 is equipped with a spindle 6 carrying a writing device 8 for recording circumferential forces on a disk 9 fixed on the spoke of a pulley 1 and receiving rotation, at each turn of the pulley 1, through worm gears a belt ratchet on the belt 18 to the shoulder 18.

2. Modification described in n. 1, characterized by replacing the spring 2 with a buffer spring 23, hinged its holder to the lever 22 and connected to a pull 24 acting on the spindle 6 of the writing device, in order to record the amount of spring compression on the disk of the recording device mounted on the lever 21.
