Description

(54) TORQUE METER

In turn, not 7 and 8 are placed between the illuminator, containing a lamp of Kalivank 9 and a condenser 10, and an optical system consisting of lenses 11 and 12, with no matching mirrors 13 and 14, and the same mirror as the mirror 15, K1pgematishi connected with the shaft 1 by means of an accelerated reduction gearbox in the form of a pair of bevel gears 10 and 17, for example, with a transfer of 1.1 fire 2 :, The light beam is directed by a mirror with a mirror ; 1kala 18 with fluorescent coating. The tachometer of 19 alustra is additionally shown on the plane of the screen, it is an installation and control of the stand

Scale 18 Ekpana

second electric motor

completed Novorot.Oh installation of the origin of reference.

In the absence of a load, tsish 3n are located relative to each other so that the slit 7 of the first disk and the shelf 8 of the second disk are blocked by the light flux from the glow lamp 9 is blocked, and, consequently, on the scale 18 there is no light image,

After switching on the bench motor 2 as a result of inertia and friction in the disk 5 supports, the slots 7 and 8 are aligned on a small sector arc, the value of which will depend jsaK on the mass of the disk 5 and the magnitude of the trunks in the supports, and on the parameters of the twist 4 p vol / m installed on the tachometer 19, the luminous flux formed by the condenser 10 passes through the partially aligned slots 7 and 8, is transmitted by the optical system 11 - 15 fia to the box 18, the screen on which the light trace appears cha The beam size is determined by the arc of the overlapped part of the sectors of disks 3 and 5, the increase in the optical system and the gear ratio of a pair of wheels 16 and 17. At the collar, the screen chambers 18 set the reference point, t, e, the end of the light of the next and the scanned beam coincides with About scales, what eliminates the error introduced by the device at a given speed of rotation.

When releasing the load (not shown in the drawing) on the scale 18, the maximum deviation of the beam generated by the optical system of the device is recorded, which corresponds to the starting moment of resistance of the monitored mechanism. In the steady state of rotation at p rpm, the magnitude of the light arc on the scale 18 will correspond to the value of the measured torque in the steady state.

1, the torque meter, which contains the drive, is equipped with two W-gs with vice-sectors interconnected by a ynpj gkm element and located between the drive and the load of the light source and the optical system with a reference node differing from that. that, in order to increase the accuracy point and the widening of the measuring range in the side of small moments, in that case and the starting ones, it is equipped with a scanning mirror, kinematically connected with the drive shaft and installed at the output of the optic. system, and the reference node is made in the form of a fixed screen with a swivel scale, placed on the path of the light flux, from a mirror scanned by it. 2, The meter in accordance with clause 1, clause 1, and also with the fact that KHHeNiaTHHecKaa the connection of the scanner mirror with the drive shaft was detected as an accelerating gearbox, HcTovtiKiw information taken into consideration during the examination: 1, USSR Author's Certificate No. 194368, kp. Q OIL 3/10, 19v5, 2, Copyright certificate USSR No. 356493, cl. Su13b / 12, 1970.
