Abstract

The invention relates to a force-measuring technique and is intended to measure the dynamic loads on the base from textile machines in three mutually perpendicular directions. The purpose of the invention is to show the accuracy of measurements by reducing the coupling of machine vibrations on elastic elements in three directions. The device contains an elastic element - cylinder 1, rigidly fixed. The supporting end face 2 on the base 3. In the force-receiving end of the cylinder there is a blind concentric hole 4 in which force-bearing sleeve 5 with collar 6 is placed. In sleeve 5 there is a blind hole 7 with a conical bottom 8 in which the ball 9 is placed, to which Measured force applied. The center of the ball lies in the plane of the silo-receiving end of cylinder 1. On the outer surface of the wall of the blind hole 4 along the cylinder 1 forming strain gauges 10.11 are used to measure vertical loads along the Z axis. At the base 3 on the surface of cylinder 1 there are two groups of resistance resistors 12 , 13, and 14, 15, oriented along the generators of cylinder 1. To eliminate the influence of horizontal loads, i.e. bending deformations, strain gauges 10, 11 included in the opposite shoulders of the bridge.

The invention relates to power engineering and is intended to determine the dynamic loads on the base of multi-support machines and equipment in textile industry.
The purpose of the invention is to increase the measurement accuracy.
Fig. 1 shows a diagram of the device according to Fig.2; 2 is a diagram of the connection of sensors for measuring the Z axis; on fig.Z - the same as. os Y; figure 4 - the X axis.
The device for measuring dynamic loads consists of a cylinder 1 rigidly fixed by a supporting end 2 on a base 3. A deaf concentric hole 4 is made in the load-receiving end of the cylinder, in which a power-supply sleeve 5 with a shoulder 6 and a blind hole 7 with a conical bottom 8 is placed, in which ball 9 so that the center of the ball lies in the plane of the force-receiving end of cylinder 1. On the outer surface of the wall of the blind hole 4 along the forming cylinder 1 are tenso-resistors 10 and 11, which are used to measure vertical Along the Z axis. At the base 3 (at a distance of 1 from the center of the ball 9) on the surface of the cylinder there are two groups of tensors 12, 13 and 14, 15 that serve to measure horizontal loads (the strain gauge 15 lies on the opposite side torus 14 and its projection in fig. 1 coincides with the strain gauge 14).
Dp exclude the influence of horizontal loads, t, e. bending deformations, the strain gauges 10 and 11 are included in opposite bridges (Fig 2), which include compensation resistors 16 and 17.
bone relative to the forces applied to the ball 9 in three perpendicular directions, which reduces the connectivity of vibrations and improves accuracy. 4 il.
To eliminate the effect of vertical loads, i.e. deformations. from compression, strain gauges 12 and 13 are included in the adjacent shoulders of the bridge (FIG. 3),
which includes compensation resistors 18 and 19; Similarly, the resistance strain gauges 14 and 15 are included in the adjacent shoulders of the bridge (Fig 4), which includes compensation resistors 20
and 21.
The device works as follows.
The loads acting from the side of the machine are transmitted through the ball 9 and the sleeve 5 to the cylinder 1. The vertical load causes compression pressure at the installation site of the strain gages 10 and 1, which they convert into an electrical signal using a bridge (figure 2), causing horizontal loads at the installation location Texthistor resistors 12, 13 and 14,15 bending tension, they are converted into electrical signals using bridges (fig.Z and 4).
The dimensions of the cylinder I and the blind concentric hole 4 are chosen so that the rigidity of the device, measured at a point, coincides with the origin and along the direction of the three coordinate axes are the same, which reduces the coupling of oscillations of various shapes in different directions and reduces the dynamic errors. Sensitivity
all three bridges are also the same, due to which the same accuracy of signal conversion in three directions.
