Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 2 As shown, a gear double-mesh error measurement system includes an inductance sensor 6, a signal conditioning circuit 7, a data acquisition card 8, a computer 9 and a display 10 connected in sequence. The sensor 6 is located at the position of the dial indicator of the original traditional gear double meshing instrument.

[0024] In this embodiment, the inductance sensor 6 adopts a differential inductance sensor (LVDT) produced by Analog Devices Corporation of the United States, the signal conditioning circuit 7 is an AD698 signal conditioning circuit, and the data acquisition card 8 is a data acquisition system developed by National Instruments (NI) of the United States. Card, computer 9 is the computer equipped with the integrated program Labview development platform based on the "graphics" mode launched by NI; AD69...

Abstract

The invention relates to a gear double-tooth error measuring system. The gear double-tooth error measuring system is characterized in that an inductive transducer, a signal conditioning circuit, a data acquisition card, a computer and a displayer which are sequentially connected are included, the inductive transducer is connected with a movable sliding plate of a gear to be measured, the inductive transducer receives change amount signals of a gear double-tooth center distance, the change amount signals pass through the signal conditioning circuit and then are converted into analog signals to be transmitted to the data acquisition card, the data acquisition card conducts analog-digital conversion on the analog signals, afterwards, the analog signals are transmitted to the computer, the computer carries out curve-fitting processing on the analog signals to obtain error curve information, and the displayer is used for displaying. Compared with the prior art, the gear double-tooth error measuring system has the advantages that examination precision and efficiency are high, and the error curve can be observed.

Description

technical field [0001] The invention relates to a gear measurement system, in particular to a gear double mesh error measurement system. Background technique [0002] During the comprehensive inspection of the gear, its situation is relatively close to the situation in actual use. The double-mesh comprehensive inspection is one of the comprehensive inspections, which is widely used in mass production of gears in batches. Usually, a double gear instrument is used to measure the comprehensive inspection of gears, and to measure the comprehensive radial error of gears. The traditional double-mesh measuring principle is as follows: figure 1 shown. The measuring gear is mounted on the static slide plate 1 and is fixed during the detection process. The tested gear is installed on the movable slide plate 3, and moves in a straight line during the detection process. The variation of the double tooth center distance is read by the dial gauge 5. Synthetic error ΔF i ″, when the ...
