SU1250908A1 - Device for determining gaps in gear transmissions - Google Patents

Abstract

The invention relates to mechanical engineering, namely to means of controlling gears. The purpose of the invention is to improve accuracy by providing elementwise determination of gaps in the transmission joints. The device includes a force sensor and an angular displacement sensor of the torque lever. When monitoring the clearances, two parameters are simultaneously recorded: the force of rotation of the shaft of the controlled gear and its angle of rotation. The interrelation of the above parameters makes it possible to determine the magnitude of the angular gap in any gear connection, including in the spline, 3 sludge. with (L

The dynamometric lever 1 is fixed and rigidly fixed by means of a coupling 3 on one of the 4 gear shafts, for example, a high-speed one. The brake is a second shaft, for example, a second shaft.

The force sensor 5 and the recorder (not shown) register simultaneously two parameters: the change in the turning effort and the change in the angle of rotation of the shaft of the controlled gear,

The points of inflection of the curve change the angle -f of rotation of shaft 4, corresponding to the beginning and end of the segments ab, cd and ef (angles,% A of the curve of change P (fig 3)

shaft 4 identifies matrices corresponding to the magnitudes of the angular clearances ji, .5% 5 j at the connections of the controlled transmission. Considering the scale of the graduation of the strain gauges of the tensoplates 7, the angular clearances and the gains1 of their choice in each individual connection of the controlled transmission are determined. To reduce the control error, the measurement process is repeated at different angular positions of the shaft of the controlled gear transmission.
