Description

A torque meter is known, consisting of an elastic element in the form of a torsion and operating according to the principle of direct measurement of the twist angle, and the measurement is measured on rotating bars with a stroboscopic backlight.

The proposed meter makes it possible to increase the accuracy and convenience of counting by using two illuminated disks with gaps, arranged in a spiral with different pitch on each disk, and a fixed screen installed in front of the disks, with digitized holes of the degree and minute scales. The remote pointer is made up of photo-motivations installed in front of the openings of the screen, the circuits of which include relays that enable the indicator lights on the remote control.

FIG. 1 shows a meter in longitudinal section; in fig. 2 and 3 - discs with slots, front view; in fig. 4 - scale of the fixed screen with digitized holes; in fig. 5 - fixed screen with photoresists, side view; in fig. 6 - remote control, view sieredi.

The torque meter consists of an elastic element in the form of a torsion 1, two illuminated disks 2 and 5 and a fixed screen 4 installed in front of the disks. The disk 2 is connected to the left end of the torsion / and the disk 3 to the right.

When the torsion is loaded with the measured torque (the moment is transmitted through the spline process 5 of the torsion), the disks 2 and 5 turn relative to each other in proportion to the torque value. Each disk (Fig. 2 and 3) has a slit arranged in a spiral, with the slits of the disk 3 have a nominal location, and the slits of the disk 2 are shifted by the vernier scale (arranged in increments different from the step on the disk 3.

Screen 4 (Fig. 4) is made with digitized holes of the degree and minute scales; Scale names are indicated near the scales. When the meter is put into operation, the following lights appear on the screen 4, when the screen is 4, and the dot; one on the degree scale, a friend on the minute. The position of the light pdih points indicates how many degrees and minutes the disk 2 has turned relative to disk 3. Then the true value of the torque of the torque is determined from the calibration tables.

In order to remotely transmit the measurement result, the remote pointer is made in the form of photoresistance 6 installed in front of the screen 4 openings (Fig. 5), whose circuits include relays (not shown) that enable the indicator lights 7 on the remote control 8. True measurement value The torque is determined as described above.

Subject invention

1. A torque meter with a remote pointer, consisting of an elastic element in the form of a torsion and operating according to the principle of directly measuring the twist angle, characterized in that, in order to improve the accuracy and convenience of reference, two illuminated disks with slits located in a spiral with different sch.chl on each disc, and fixed in front of the disks fixed screen with digitized holes of the degree and minute scales.
