Corresponding flank profiles are defined by a mathematical function enabling progressive curvatures of profiles. This function is used to define a basic worm profile in the axial plane, wherefrom worm flank surface and mating worm gear profile and flank surface are derived. Furthermore, cutting tools for manufacturing such wormgearing are defined. Kinematic circumstances are discussed in detail,thus disclosing the emergence of contact lines (surfaces). The essential characteristics of the proposed wormgearing are that its entire teeth flank surfaces in contact are involved in power transmission and that concave-convex contacts exist anywhere on flank surfaces. Thus, improved properties in power transmission and lubrication can be expected, consequentlyresulting in lower energy losses and lower wear"},{"@xml:lang":"sl","#text":"Članek obravnava polžasto zobniško dvojico, pri kateri imajo boki zob polžnikakonveksno, boki zob polža pa konkavno obliko. Oblika pripadajočih zob je definirana z matematično funkcijo (enačbo), po kateri dobijo profili bokovzob progresivno naraščajočo ukrivljenost. S to funkcijo je v aksialni ravnini določen osnovni profil in s tem oblika zoba polža, s katerim je določen tudi profil zoba polžnika in kontaktna površina bokov zob. Poleg tega so s to enačbo določene tudi oblike rezalnih robov orodij (nožev) za izdelavo takih polžastih dvojic. Podrobno so opisane kinematske razmere v kontaktnih točkah in pokazane so kontaktne linije. Bistvo oblike zob predlagane polžaste zobniške dvojice je, da je vsa površina zobnih bokov udeležena pri prenašanju obremenitev od polža na polžnik in da je praviloma v vseh dotikališčih konkavno konveksna oblika dotika. Taka oblika zob poveča zmogljivost prenašanja moči, izboljšuje mazalne sposobnosti, zato so izgube moči manjše in obstojnost površin večja"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-XI2RBKUL","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-XI2RBKUL"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-XI2RBKUL/ab25c6a7-b53f-4f15-b7a3-268b6e81ff23/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-XI2RBKUL/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-XI2RBKUL"}}}}
