Embodiment 3

[0046] This embodiment provides a detection method based on the detection system described in Embodiment 2, the steps are:

[0047] 1. While starting the continuous retreat line, the light source transmitting end 3 of the photoelectric sensor at the position of each gear coupling 30 is controlled by the PLC control system to continuously emit light signals to its receiving end 4;

[0048] 2. The PLC control system scans the feedback signal of the photoelectric sensor at the position of each gear coupling 30 with a signal scanning period of 100 ms. When the gear coupling 30 at a certain position has wear, slipping and broken teeth , the receiving end 4 of the photoelectric sensor at this position converts the received optical signal into an electrical signal and feeds it back to the central processing unit of the PLC control system;

[0049] 3. After receiving the signal, the central processor of the PLC control system sends an instruction to the alarm at the corresponding posi...

Description

technical field [0001] The invention relates to the field of continuous annealing production lines, in particular to a gear coupling fault detection device, system and method for continuous annealing lines. Background technique [0002] There are a large number of main drive motors and furnace roller motors in the silicon steel continuous annealing line. These motors and their driven shafts (rolls) are usually connected by gear couplings. Since the gear couplings bear a large load, Serious tooth wear will occur during use, and even lead to slipping or broken teeth. Among them, once the above-mentioned failure occurs in the gear coupling at the main drive motor, the tension of the strip steel will fluctuate; and if the above-mentioned failure occurs in the gear coupling at the furnace roller motor, the speed of the furnace roller will be reduced, and even the furnace roller will be damaged. Become a free roll, resulting in a speed difference between the furnace roll and the ...
