Abstract The present invention relates to a deviation-rectifying device of abrasive belt for wide belt grinding machine, its method and driven roller heat-insulating method. The shaft of the driven roller adopts the bearing seat positioned on the shaft seat, and the shaft of the driven roller is covered with hollow sleeve, and spaced between them, the hollow sleeve is covered with abrasive belt guide wheel and hollow sleeve seat, the abrasive belt can be rotated about hollow sleeve, the hollow sleeve seat and hollow sleeve and fixedly connected, and the side surface of abrasive belt guide wheel is equipped with roller, and the roller is positioned in the roller seat. Said invention possesses the following advantages: 1. adrasive belt guide wheel and roller positioned on its side surface and roller seat matehed structure design can effectively implement automatic deviation rectification of belt; 2. adopting hollow sleeve to isolate abrasive belt guide wheel from driven roller to prevent damage to bearing due to abnormal temp.; and 3. stable and reliable work performance, it has no need of maintenance basically.
