Description

Typically, existing instruments and methods for capturing indicator diagrams, whether in the form of a parallelogram or eccentrically mounted on the end of a shaft of a finger, swinging rods, etc., have a number of inconveniences in using them. Besides the fact that they are difficult to catch for engagement with the cord, they last three days a cord, give precise movement, moreover, give only one any moment (type of diagram) on which the normal or shifted diagram is installed. If it is desirable to remove the one and the other, then you need to install two drives.

To eliminate these drawbacks, a device is provided for transmitting the eccentric drive of the indicator drum from the machine shaft, in which an arc located eccentrically to the axis of the shaft shaft is used, which is used for shifting and fixing the bushing with the guide for the eccentric drive connected to the clamp, connected to a rod which, in order to obtain shifted diagrams, deviates by an arc from the normal position.

The drawing shows a schematic general view of the device in perspective.

Fortified to the tested ma (336)

The tire arc 7 is moved by the slider 2, carrying a guide for the rod 3, which is brought into a straight-line motion by the collar 4, which slides along the eccentric 5, mounted on the free end of the main shaft of the machine. Arc f has two stops b, 7, limiting the movement of the rod 3 90 °. The end of the stem 3 has a recess 8, making it possible to completely whip the cord through, move it over the rollers 9, JO and 7 / and then through the roller 72 release it exactly in the center of the shaft to the indicator.

If you take the protruding end of the guide, like a knob, you can move slider 2, do not release the indicator, and get a series of successive diagrams from normal to 90 ° shifted and watch for gaps, premature flashes, normal course or remove normal and offset diagrams both individually and together.

The removal and shortening of the cable is made on the move by raising or lowering the cap J3 holding the roller 9. The device can be adapted to be connected to the rev counter or tachometer attached to the end of the rotating shaft.

The subject matter of the invention.

A device for transmitting movement of the indicator to the drum using an eccentric drive from the machine shaft, characterized by the use of the axis of the arc machine / centered on the axis of the arc machine /, designed and in turn for shifting

it and fixing in the desired position the slider 2, which carries the guide movement associated with the collar 4 of the drive eccentric and serves to deflect the rod 5 from its normal position, in order to obtain diagrams offset from one another.
