Abstract

PURPOSE:To detect the abrasion quantity of the gears of both the driving side and the load side, by measuring the backlash between both gears from the difference of time intervals between the pulses of the driving side and the load side in the forward/backward revolution mode of both gears and via a detector of one pulse/revolution. CONSTITUTION:The time interval t1 from the driving side pulse A of a shaft 4 at the driving side 2 to the load side pulse B of a shaft 5 at the load side 3 is measured along with the cycle 1/f1 of the pulse A or B. Then the shaft 4 is rotated backward to measure the time interval t2 from the pulse B to the pulse A along with the cycle 1/f2 of the pulse A or B. Based on these data, the backlash is calculated. In such a way, the backlash or the abrasion quantity of a gear can beeasily detected without releasing the gear coupling. Thus the gear coupling can be checked accurately with no trouble. This process prevents previously the breakdown of the gear.
