(1) The cost is too high. The imported bearing 88y0043C3 is too expensive; just replace the mandrel with a value of about 0 yuan; 88y0043C3 can be completely replaced by the domestic standard bearing 6004.
(2) There are problems in sealing. Especially the water roller; some part of the shaft end needs to be immersed in the dampening solution; when the pH value of the dampening solution is less than 6, the bearing will be corroded quickly; the ball can not be changed normally; the end causes the bearing rust to die. Running inside and outside the ring; when the time is severe, the rubber roller body, bearing and mandrel are completely invalid.
(3) The problem of axial force. In addition to the damage caused by the infiltration of the fountain solution; the bearing will also present the appearance of “scattering”; that is, the bearing balls are scattered from the “flower basket” onto the drum; the plate cylinder and the blanket cylinder are made. The rubber roller and other appearances are severely damaged.
2. Solution (1) Cheap mandrel; adjust the scale; replace the imported bearing 88y0043C3 with the domestic standard bearing 6004.
(2) Correct the rubber roller body; set a firm sealing layout; to avoid dampening liquid immersed in the bearing. We use 5 SSC production lines; Shanghai Goss has improved the above two problems according to our drawings.
(3) Differentiate the axial force of the 6004 ball bearing; that is, add a set of 51104 thrust bearings at the shaft end. Currently; we are still gradually improving the shaft end layout of all SSC production line rubber rollers; from the application of the improved rubber roller The role is very ruthless. Nowadays; whether it is the use of water roller is still the ink roller; only the rubber surface is no problem; the shaft end layout, the bearing is certainly no problem; and can be used for a long time. After improvement; in one application cycle (printing every day) 10 hours; usually a rubber roller 6) service life is about 1 year); even when replacing the rubber roller, the bearing will be replaced by a new one; it can save about 600 yuan. There are 16 towers in the middle of the printing; each tower has 48 rubber rollers; roughly accounting; after improvement; can save the newspaper more than 400,000 yuan in one application cycle.
