Title: Device and method for detecting chain elongation
Inventor: HONDA HIROHIKO
IPC: F16G13/02
Filed: 2000-02-22
Abstract: PROBLEM TO BE SOLVED: To automatically detect chain elongation. SOLUTION: This chain elongation detecting device consists of an encoder 12, a sensor 11, a counter 17 counting a difference in distance between a signal from the sensor 11 and an origin signal of the encoder 12 by the number of pulses of the encoder 12, a first register 18 storing the number of pulses before a chain 1 elongates as the reference number of pulses, a second register 19 storing the number of pulses counted while the chain 1 is driven as the number of measured pulses, and a comparison and control means 20 comparing a difference in the number of pulses of each register 18, 19 with a reference value.
