主要振因是当工作辊轴承座与牌坊之间间隙过大时，接轴弧形齿的啮合冲击将激起轧辊横向振动。
The vibrations are caused by spindle curved tooth meshing impact when the gap between work roller bearing block and frame is oversized.
本实用新型涉及用于金属轧制的轧辊的安装、调节或更换，具体为一种矩形轴承座旋转定位装置。
The utility model relates to a rectangular bearing block rotary positioning device used for the installation, the regulation or the replacement of a roll used for rolling metals.
同时，设在上下支承辊装置侧面或机架上的压紧缸、腰块上的移动缸可实现轧辊轴承座与机架间的无间隙轧制。
In addition, using the hold down cylinder, the waist block and the shift cylinder can realize gap-less rolling.
