Abstract: 

The article presents main types of spiroid transmissions. It describes the advantages when choosing transmissions of a worm-gear class and calculates the efficiency for them. Power losses in gearing account for a considerable share of losses in worm-gear transmissions. It is proved that the efficiency of transmission decreases at increase in transfer number in a worm gear pair. With the sliding speed growth, the coefficient of a sliding friction decreases. The choice of lubricants for spiroid gearboxes is a relevant problem, despite their advantages before worm ones with respect to load ability and efficiency. The authors describe a full-scale program of tests executed when developing new oils and additives to them for toothed gears. This work deals with the assessment of antifrictional properties of gearbox oils for spiroid gearboxes. The tests were carried out on a special stand, made as an open circuit, the diagram of which is provided in the article. The tests were performed in three steps (the paper describes each of them). Studies have been conducted for three grades of gear oils (TM-5-18 "TAD-17", TM-4-18 "U-tech Forward", TM-4-12 "LUXOIL"), the best of which, with respect to anti-friction properties, is oil TM-4 -18 "U-tech Forward". The efficiency dependencies of PC31.5-11 and PC31.5-81 spiroid gearboxed are presented depending on the moment T2 tested with the TM-4-18 “U-tech Forward” oil.
