Title:
トランスミッションベルトの摩耗を検知し、ベルト駆動システム性能を監視する装置及び方法
Document Type and Number:
Japanese Patent JP2009531604
Kind Code:
A
Abstract:
An apparatus and method to monitor endless belts and related belt drive systems by non-contact sensors for wear or an anomalous function, determining the state of belt drive system and detecting early stages of belt and system failure. A sensing unit featuring one or several independent sensor elements is placed near a belt of a polymer matrix with a fiber cord load bearing core to monitor several simultaneously occurring normal modes of operation. The sensor can determine soundness of the whole timing drive continuously by processing the collected signal and detecting structural damage. The collected data is processed by a microcontroller integrated with the sensor. The apparatus and method uses a non-contacting capacitor array having sensing element(s) connected to electronic circuitry that is adapted to sense the dynamic capacitance change coupled with electrocapacitive and piezoelectric effects exhibited by the belt. The sensor continuously monitors the belt during normal operation.
