Sphere of practice and quality identification

Practice and quality of spherical identified 2020 - 07 - 02 Wang Zhanguang of sphere tile, everybody is not strange, in cement industry is mainly used for rotary kiln tube mill and support, the support by the spherical bowl, spherical tile, tile line. For spherical tile supporting device, spherical bowl inside spherical with spherical outer sphere, spherical watts inside and outside cylinder liner, watts cylinder liner inner cylinder and axis of cylinder is the key contact precision, including spherical bowl in contact with the sphere of accuracy, guarantee of the spherical self-aligning flexible, through a range of rotation, guarantee the tile line a good contact with the shaft; Within the sphere of cylinder and the lining of the cylinder is a good contact, ensure uniform tile lining stress, avoid partial overload; Bushing precision of contact with the shaft in order to ensure uniform throughout the tile surface contact, reduce friction, avoid fever. If you found the contact accuracy when installation or maintenance is not in conformity with the requirements, you need to practice, the following is the accuracy of tile practice of guarantee the quality of spherical method and differential method. For newly installed tile, need to contact precision control of test standard, if not qualified, you need to practice. Specific means is: 1. Spherical surface of the tile and tile practice should be inspected first contact surface is clean, besmear after the red lead, and rub evenly, then inside spherical tile in tile seat, and let the spherical tile along the axial and circular rotation, turn around 10 degrees, and then hanging out spherical, check the contact spot, if not appropriate, spots can be scraped off, continue to grind, until the contact spot distance less than 10 mm, idea at the same time maintain contact Angle for natural Angle, contact spot within the Angle from the bottom to the side of heavy and light, about the size of the Angle without limit. In terms of the contact width and should not be less than a third of the overall width is not more than two thirds, lighter spot is also gradually outward from a center; For tile bridge central open slotted, near the groove of the contact spot should be lighter, otherwise easy to produce in this indentation, is not conducive to sphere of free rotation. 2. Spherical Vanessa and tile cylinder liner practice about spherical Vanessa and practice of the liner, cylinder is measured first check whether the width dimension of sphere tile and tile lining tile skirt closed size to match, to be able to human pressure into or sticks to knock into the advisable. Grinding method and grinding method and spherical watts are the same, but not in axial rotation, only ring to turn, contact spot spacing is less than 5 mm, the weight of the spot is from bottom to the edge of the lighter. About Angle is also a natural as well, contact is given priority to with writings here, ensure that the bearing capacity of the clay liner. 3. Tile practice of lining inner cylinder and axis tile line contact with the shaft of the highest accuracy requirements, methods of research and the same, but different precision, here requires the contact spot spacing with 3 mm advisable, while requiring skirt good contact with the roller thrust plate, and too hard to polish off, keep contact evenly; Third, require tile skirt R Angle and shoulder R Angle contact good or not, or fever may emerge from this. For lining with the axis of research, and often more than the old new, less about the old tile practice, it is advisable to Angle at 60 degrees or so, if the Angle is too small, the local stress of big, wear fast, not conducive to life, although be helpful for the adjustment of tile, but no fever is better? Before the fever, basic is the contact accuracy caused by insufficient or spherical tile is not flexible, actually relation with Angle is not big, because the smaller the Angle, the higher the pressure, the larger the friction coefficient, the more heat. Conclusion: in fact for spherical watts, a sphere is the flexible and ensure tile with slight rotation a good contact with the shaft lining, avoid partial pressure is too large, increase the coefficient of friction and heat; 2 it is to ensure that the lining with spherical watts writings, ensure that the bearing capacity of the clay liner; 3 it is tile line contact with the shaft precision, large heat generated local pressure is too large to avoid heat; At the same time, it's important to note that R contact and contact with precision of the thrust plate. To predict the contact of precision, but also can be roughly judgment through touch, is a time when in the grinding of rock, judging by hand, if feel moist fleshy feeling, that is about the same, if too fast that way, perhaps only several contact points, if death is likely to be stuck, hard point between the ability of resistance to bending moment. About the spherical contact precision of identification is here, welcome to comment. （ Source: wisdom cement)
