【発明の詳細な説明】
本発明は弾性バネを介して結合された回転軸カップリン

したトルク計測用フレキシブルカップリングに関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flexible coupling for torque measurement in which a rotary shaft coupling coupled via an elastic spring and a relative displacement detection mechanism for torque if measurement are mounted and integrated.
従来回転軸カップリングは2つの回転軸相互を結合し動

構造としたものである。Conventional rotary shaft couplings connect two rotary shafts to each other to transmit power, and the torque sensor of the rotary shaft torque detection device detects the torsional displacement angle between the gage points of a specially prepared torsion shaft. The structure is such that rotation and shaft torque can be measured.

ならざるを得ないものである。These two have independent structures and there is no functional relationship between them. Therefore, in the latter case, when the drive side and the driven side are connected axially, the connection distance is longer by the torsion axis. This increases the installation area, and in some cases, it may be necessary to install a bearing to support the torsion shaft.
Further, as a matter of course, a rotating shaft coupling is required at both ends of the torsion shaft, which complicates the mechanism and inevitably increases the price.

ることは明らかである。Plunge (6) the displacement angle generation markers (7) and (8),
If the magnetic protrusions are arranged at equal intervals on the outer periphery of (6), then
Magnetoresistive pulse detectors are used for the marker sensors (11) and (12) of this kettle, and when a magnetized magnetic pole is provided on the outer periphery of the flange, it becomes a pulse voltage detector based on changes in magnetic flux. If the marker (7L (8)) is a scale with different colors as an optical detection mechanism, it will also become a reflected light for the projected light, and this will be detected optically, and the detection method is is not particularly limited. In either case, since the flange is a flexible coupling via an elastic spring, the marker detection sensor (1
1) and (12) are preferably of a type that detects the flange (5L(6) in a non-contact state from the viewpoint of mechanism and operation and maintenance.Next,
If it is assumed that a helping force is delivered from the driving shaft (1) to the driven shaft (2) side in a rotating state, the coil spring (9) of this coupling will be twisted by that angle in response to the torque of the delivered power, A relative angle is maintained between the flanges (5L (6)). In response, the marker sensors (11) and (12) generate electrical or optical pulse signals corresponding to the displacement angle. Since a phase angle occurs between mutual pulse signals, this is processed by a signal processor (13),
If only the phase angle is displayed, the flanges (5) and (6)
), as well as the relative displacement angle of the coil spring (9).
If we specify the product of the elastic constant and the axial torque,
Furthermore, it is clear that by calculating the product with the rotational speed, the power delivered to the shaft can be obtained.

If the output from 7L (8) is in the same phase and the output instruction is adjusted to zero, it is convenient for calculation processing, and the phase difference due to the relative displacement angle between the flanges can be used to calculate the relative displacement angle, rotating shaft torque, output power, etc. It is possible to give instructions. It is well known that phase difference detection between two pulses of variable frequency in a rotating state can be processed by an arithmetic circuit that eliminates the variable frequency, and there are various methods for this.
