Abstract
Description
Vynález sa týká posúvaeieho mechanizmu zloženého najmenej z dvoch ozubených tyčí na prenášanie změny pohybu s přerušením záběru ozubenia a jeho istením, prlčom ozubené tyče sú spojené v upínacom bloku.BACKGROUND OF THE INVENTION The present invention relates to a displacement mechanism comprising at least two toothed racks for transmitting a change of movement with an interruption of the gear engagement and securing thereof, the toothed racks being connected in a clamping block.
Doteraz známy posúvací mechanizmus tohoto druhu, tvořený tažnou a posúvacou ozubenou týčou, uloženými v upínacom bloku, rovnakej dížky, ozubených tyčí a s ozubením po celej dížke, má za následok to, že je použitelný na prenášanie změny pohybu bez možnosti prerušenia záběru ozubenia a jeho istenia. Ozubené tyče májů rovnakú dlžku a ozubenie je po celej dížke, pričom ozubenie musí ostat stále v zábere, nle je možné vymedzit čas a dížku pohybu ozubených tyčí nezávisle od seba. Okrem toho je nutné vyrobit celé ozubenie v najváčšej pres nosti, při vyššej spotrebe materiálu a elektrickej energie, čo podstatné předřazuje výrobu.The prior art shifting mechanism of this kind, consisting of a pulling and shifting toothed rack mounted in a clamping block, of the same length, of toothed racks and with toothing over the entire length, makes it usable for transmitting movement changes without interrupting gear engagement and locking . The toothed racks have the same length and the toothing is all over the length, while the toothing must always be engaged, but it is possible to define the time and length of movement of the toothed racks independently of each other. In addition, it is necessary to produce the entire toothing in the highest precision, with a higher consumption of material and electric energy, which is essential to production.
Podstata riešenia podl'a vynálezu spočívá v tom, že ozubené tyče sú rozmerovo rozdielne, ozubenie je, vyrobené len na časti ich dížky pře vykonanie pohybu v čase a dížke posúvaniia. Ozubenie je vytvořené tak, že pri přerušení záběru ozubenia súčasne sú tyče vzájomne istené pomocou drážky a výstupku, vytvořených na ozubených tyčiach.The principle according to the invention consists in that the toothed racks are dimensionally different, the toothing being produced only on a part of their length before the movement in time and the length of the displacement. The toothing is designed such that when the tooth engagement is interrupted, the bars are secured together by a groove and a projection formed on the toothed racks.
Hlavně výhody usporiadania posúvaeieho mechanizmu spočívajú v tom, že umožňuje prerušenie záběru ozubenia, vzájomne tyče voči sebe istí, pričom odpadá výroba dlhších ozubených tyčí, zníži sa materiálová a energetická náročnost, ulahčí sa spósob montáže, zvýši sa produktivita práce ako i možnost' róznych kombinácií ozubených tyčí nezávisle od seba, jednotlivo alebo v pároch s možnosťou změny směru pohybu v róznych časoch a dížkach, změn uhlov ozubenia.The main advantages of the arrangement of the shifting mechanism are that it allows interruption of the gear engagement, the bars are locked against each other, eliminating the production of longer toothed racks, reducing material and energy consumption, facilitating assembly, increasing labor productivity and the possibility of various combinations independently of one another, individually or in pairs, with the possibility of changing the direction of movement at different times and lengths, changing the angles of the toothing.
