In our work we consider prevent wear of the saw tooth saws cylinder and shaft by mathematical analysis of the saw cylinder at different shaft lengths and number of blades. To prevent wear on cutting cylinder, we determine the optimal cross-flexural vibration of the shaft with respect to time and along the length of the shaft. Model simulated the transverse vibrations with different amounts of drinking and between saw gaskets brought the best option, which has a positive effect on the strength of the shaft. As a result, we have developed two staggered cylinders saw in one of the working chamber gin, which reduces bending vibration, but it increases efficiency.
For the accuracy of the results, the study was carried out for three years. The average of each factory gins was chosen. Comparison of fiber properties processed in different cotton processing plants, with different models of fiber separators. Each sample of fiber grade 1 Namangan 77 raw cotton was obtained as a result of ginning with such factory gins 4DP-130.5 DP-130, 3HDD and Lummus gins in Namangan region. The Fiber properties of all samples were measured with the Advanced HVI Fiber Information System, to determine the yield of short fibers. The main purpose of the study is to determine which model of sawing gin to produce more short fibers. For next modernization working parts of other model gin for increasing quality of fiber.
Using the above data on the manufacture of grates and taking into consideration the bending vibrations of the saw cylinders and displacement of the grates under dynamic load. Taking into account the primary factors of sectional and individual grates ribs also in order to prevent cross-displacement of grates ribs. We modeled and introduced a new type of grates ribs for a single- chamber and two-cylinder gin, which is comprised of the top and bottom, grates ribs aligned with three brackets and tightening laths with a new type of fastening respectively. In the article, consider the simulated static load experimental model of a new grate ribs lattice, which allows eliminating lateral. Displacement of ribs at dynamic loading.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
