PROCEDE DE MESURE DES DEFAUTS D'UNE CHAINE CINEMATIQUE

For measuring the defects in a kinematic chain consisting of two toothed gears (1, 2), an incremental sensor (9, 10) detecting the passage of markers (7, 8) fixed to the gear is placed in proximity to each of these two gears, the frequency of the pulses (23, 24) produced by the sensors is multiplied...

Zusammenfassung:For measuring the defects in a kinematic chain consisting of two toothed gears (1, 2), an incremental sensor (9, 10) detecting the passage of markers (7, 8) fixed to the gear is placed in proximity to each of these two gears, the frequency of the pulses (23, 24) produced by the sensors is multiplied using multipliers (25, 26), so as to obtain a theoretical ratio of the frequencies equal to one, and these frequencies are compared. In order to multiply the frequencies, a constant number (N25, N26) of pulses is produced at each of the pulses of the sensors.
