Transport roller for conveyor belt - has speed monitor located in ball bearing mounted roller sleeve to generate frequency related signal

摘要

The overspeed monitor within the transport roller (1) is fixed on one or both pins (2, 3) and is coupled to the rotatable outer sleeve (12) of the roller. The speed monitor is positioned centrally and electrical cables (14) are fed axially outward from it through one or both pins. The speed monitor (16) is coupled to the outer sleeve by a follower. The surface of the roller is roughened. The three electrical cables (14) feed the supply to the conveyor belt. The speed monitor generates a signal related to the frequency of the rotating outer sleeve (12).
