Technical Field
[0001] The utility model relates to an oil retaining device for a photoelectric encoder of a guide roller of a cold rolling mill, belonging to the technical field of cold rolling production equipment in the metallurgical industry. Background Art
[0002] The guide rollers at the entrance and exit of the cold rolling mill need to be installed with a photoelectric encoder for speed measurement. Since the guide rollers are prone to axial movement during high-speed operation, the photoelectric encoders are generally installed in a hollow shaft-holding form. During installation, the extended shaft of the guide roller needs to be installed in the sub-mouth on the end side of the guide roller. The lubricating grease added to the bearing on the end of the guide roller overflows from the end face, contaminating the photoelectric encoder installed on the end side, causing the photoelectric encoder to be frequently contaminated and damaged.

The guide roller and the photoelectric encoder are respectively mounted on both sides of the guide roller bearing seat. The photoelectric encoder and the guide roller bearing seat are connected together by a fixed block and a fixed spring piece. An oil baffle plate is provided between the photoelectric encoder and the guide roller bearing, and the oil baffle plate is fixed on the extension shaft of the photoelectric encoder.
[0006] The fixed block is fixed on the guide roller bearing seat, one end of the fixed spring piece is fixed on the fixed block, and the other end of the fixed spring piece is fixedly connected with the photoelectric encoder.
