Liner deformation under pressure in print

The printer accepts the drum shaft first attack bending load deflection, the principle of choice is generally allowable deflection parts as follows: ① deflection machines will not continue to work; ② deflection make parts pose a serious scrap; ③ deflection to make the machine function beyond the permissible limit . Machine tools and gear shaft may experience the following general formula strike: the machine axis: reducer axes: on one specific axis is necessary based on practice and application loading conditions and equipment requirements to determine accuracy. Printing Machinery attributed precision machinery, printing equipment allowable deflection roller shaft that is printed by the third technology and printing quality to choose. The successful completion and printing quality is good or bad depends on the printing process at a certain printing pressure roller shaft surface print full contact, so that the ink is transferred from the plate to the exact paper surface. There is a close relationship between the ink transfer and printing pressure, only when the printing pressure between two distances, talent get good prints. When printing pressure between the rollers to ensure good contact with their surface, while making drum attack corresponding deformation. After the onset of the force above the axis of the drum shaft upward bending deformation following the attack down the roller axis bending deformation, deformation of the drum base maximum, minimum two. Roller body is made of metal material, in order to ensure the printing press roller surface after the application of good contacts, the drum surface coated with packing (packing consists of paper, blankets or cardboard). In the print pressure deformable liner attack, the drum surface is used to compensate for manufacturing, installation errors and the drum shaft at the onset of the print pressure deflection, it is necessary to print the drum liner deformation than or equal to the maximum bending roller axis the amount of deformation, failure is not printing condition.
