G.F. Prokof’ev Complete text of the article:Download article (pdf, 0.9MB )UDС621.935DOI:10.17238/issn0536-1036.2018.1.99AbstractBand saws, which have found the wide application in sawmill due to the small width of cut, low surface roughness of saw-timbers and the possibility of sawing large diameter logs, have a number of drawbacks: low sawing accuracy at high cutting speeds, low durability of saws, large overall dimensions and metal capacity. Based on the developments and technical solutions, we present an experimental band saw with a saw, moving along curved guides, and their working surface is in the form of aerostatic bearings. The research has shown the undeniable advantages of the unit compared to traditional machines with saw blades: the sawing accuracy is greatly improved due to the reduction of the free lеngth of the saw by a factor of 5-6 and balanced running and inertia of pulleys; durability of the saw increases 20 times and more; overall dimensions and metal consumption are reduced. The developed band saw with curvilinear aerostatic guides has the advantages, but we should continue its further improvement in two directions: improving the cutting unit to increase the rigidity and stability of the saw, and consequently, the sawing accuracy; modernization of the saw drive mechanism to improve the reliability of its operation. The paper presents some technical solutions for the band saw design with curvilinear aerostatic guides.AuthorsG.F.
