Gravure Roller

Patent Application No.5
Abstract: The utility model discloses a cooling roller of a gravure printing machine. Its closed end journal bearing is a concentric rolling bearing, which is characterized in that: the water inlet and outlet end journal bearings are designed to journal bearing in the journal circumferential direction. Point supported. In order to make the force more even and the frictional torque is smaller, the above-mentioned three-bearing support can be designed as a floating-point support type of three rolling bearings in which the journal circumferential direction is uniformly distributed at 120 degrees. In the present invention, the coaxial support of the large-size bearing supported by the water inlet and outlet journals is changed to the floating-point support type of three ultra-small rolling bearings in which the journal circumferences are distributed at 120 degrees each other. When the roller self-weight and the material belt force are equal in size and direction is opposite, the friction torque is the lowest, so the material belt is more convenient to run, which helps to ensure the printing accuracy, the structure is simple, and the cost is low.
