Abstract
Przedmiotem wynalazku jest przekładnia ślimakowa bezluzowa, przeznaczona do stosowania w mechanizmach precyzyjnych, a zwłaszcza do zastosowania w układach do bezluzowego przemieszczania przestawianych zespołów urządzeń technologicznych, przyrządów pomiarowych lub obróbkowych. Przekładnia ślimakowa bezluzowa, której ślimak posiada, przynajmniej w części długości swojego uzwojenia, wydrążenie osiowe o średnicy mniejszej od średnicy dna wrębów, przy czym ślimak jest osadzony suwliwie na trzpieniu napędzającym oraz zawiera mechanizm przesuwny w celu zapewnienia odkształcenia przez osiowe ściskanie uzwojenia ślimaka, charakteryzuje się tym, że ślimak (1) w podstawie dna zwojów posiada cienkie wycięcia (8) tworzące podatne żebra (7) a linie śrubowe żeber pochylone są pod kątem pochylenia β różnym od kąta wzniosu γw linii śrubowej na walcu dna zwojów, zgodnie z kierunkiem skrętu zwojów linii śrubowej ślimaka. W innej postaci wykonania przekładnia ślimakowa bezluzowa charakteryzuje się tym, że ślimak (1) w podstawie dna zwojów posiada cienkie wycięcia (8) tworzące podatne żebra (7) a linie śrubowe żeber pochylone są pod kątem pochylenia β mniejszym od 0°, czyli przeciwnie do kierunku skrętu zwojów linii śrubowej ślimaka.The subject of the invention is a backlash-free worm gear, intended for use in precision mechanisms, and in particular for use in systems for backlash-free movement of adjustable sets of technological devices, measuring or machining devices. A backlash-free worm gear, the worm of which has, at least in part of the length of its winding, an axial cavity with a diameter smaller than the diameter of the bottom of the slots, wherein the worm is slidably mounted on the driving pin and includes a sliding mechanism to provide deformation by axial compression of the worm winding, is characterized in that the worm (1) in the base of the bottom of the turns has thin cutouts (8) forming flexible ribs (7) and the helical lines of the ribs are inclined at an angle of inclination β different from the angle of rise γw of the helical line on the cylinder of the bottom of the turns, in accordance with the direction of twist of the turns of the helical line of the worm. In another embodiment, the backlash-free worm gear is characterized in that the worm (1) has thin cutouts (8) at the base of the bottom of the coils, forming flexible ribs (7), and the helical lines of the ribs are inclined at an inclination angle β of less than 0°, i.e. opposite to the direction of the twist of the helical lines of the worm.
