The CAD Modelling Possibilities of Gear Pairs by Two Ways in the Mechanical Engineering Practice
205-219Megtekintések száma:151The GearTeq 2021 software is a complex gear designer software which is capable to design different types of gears based on the initial geometric parameters by the user. Naturally, the users’ appropriate knowledge for the gear theorem and the manufacturing technology is indispensable for the design. The possibilities of the software are shown in this publication. The designed gear pairs are usable for different engineering fields (robots, working machines, vehicles, etc.).

ZF6HP26 típusú váltó áttételének a meghatározása
48-63Megtekintések száma:154Az automatizálás egyre nagyobb mértékű elterjedésének köszönhetően megjelentek automata sebességváltók, amelyek áttétel módosítása a sorba kapcsolt bolygóművek megfelelő elemeinek fékezéséből, illetve összekapcsolásából adódik. A tanulmány középpontja egy ZF6HP26 típusú sebességváltó. A sebességváltó szétszerelése után a megszámolt fogszámok ismeretében levezettük az áttételeket a szakirodalomban publikált fordulatszámegyenletek felhasználásával. Az egyes fokozatok áttételeit paraméteresen vezettük le, amelybe a fogszámok behelyettesítésével megkaptuk a gyártó által is publikált áttételeket.

Analysis of Conceptual Solutions of Universal Helical Geared Reducers
64-72Megtekintések száma:154Geared reducers are mechanisms designed to reduce the number of revolutions using geared elements and nowadays they present one of the most commonly used types of mechanical transmissions in mechanical engineering. Due to the different shapes of geared elements, there are different types of geared transmissions: helical, bevel, worm, special and combined transmissions. This paper analyses only helical geared transmissions, since there is a great extent of whole this matter. Helical transmissions are analysed only with external helical gearing, since internal geared pairs represent a special and very large group of gears. Within the external helical geared transmissions, only torque transmissions are analysed, while the transmissions of motion are not analysed and they represent another large group of transmissions. Only universal gear reducers with axial, or almost-axial, parallel shafts are considered (two-stage and three-stage transmissions). Although, single-stage gear reducer produced with parallel shafts are not considered by the paper in order to reduce the area of researching. Gear reducers are most commonly delivered to customer with electric motor, known as motor geared reducer, and they are studied here extensively. Gear reducer can be also delivered without motor, only with input shaft. The basic aim of this paper is to present all characteristics and specificities of motor geared reducer in one place.
