Squeal and vibration characteristics of a VTR (video tape recorder) guide roller are investigted experimentally and a mechanism of squeal generation is considered. The results show that the squeal frequency (about 2〜5 kHz) is the same as the guide roller vibration (whirl) frequency and it is 35〜60 times larger than the guide roller rotational speed (50〜110 rps) in most cases. The guide roller rotates and whirls in the tape running direction (a forward whirl) with a nearly circular vibration orbit. The whirl (squeal) frequency can be estimated from the assumption that the guide roller rotates and whirls around the fixed shaft without slip. These indicate that the squeal generates by means of a guide roller forward whirl due to a dry friction acting between the guide roller and shaft.
