Description

Изобретение относится к машиностроению.The invention relates to mechanical engineering.

Известна упругая зубчатая муфта, содержащая ведущую полумуфту в виде зубчатого колеса с внутренними зубьями и ведомую полумуфту с установленными в ней шестернями, входящими в зацепление с внутренними зубьями ведущей полумуфты, а также упругие элементы в виде пакета пластин, связанных с шестернями £ 1 J.A resilient gear coupling is known that comprises a drive coupling half in the form of a gear wheel with internal teeth and a driven coupling half with gears installed therein that engage with the internal teeth of the drive coupling half, as well as elastic elements in the form of a plate package connected to £ 1 J. gears.

Однако известная муфта обладает недостаточными нагрузочной и упругодемпфирующей способностями, так как упругие элементы закреплены на торце ведомой полумуфты и имеют консольное нагружение от срезов шестерен.However, the known clutch has insufficient loading and elastic-damping capabilities, since the elastic elements are mounted on the end face of the driven coupling half and have cantilever loading from the gear sections.

Цель изобретения - повышение нагрузочной и упруго-демпфирующей способности муфты.The purpose of the invention is to increase the load and elastic-damping ability of the coupling.

Поставленная цель достигается тем, что в упругой зубчатой муфте, содержащей ведущую полумуфту в виде зубчатого колеса с внутренними зубьями и ведомую полумуфту с установленными в ней шестернями, входящими в зацепление с внутренними зубьями ведущей полумуфты, а также упругие элементы в виде пакета пластин, связанных с шестернями, шестерни выполнены с двумя радиальными пазами, расположенными под углом друг к дру5 гу, причем концы упругих элементов закреплены в упомянутых пазах и образуют совместно с шестернями замкнутый контур.This goal is achieved by the fact that in an elastic gear coupling containing a leading coupling half in the form of a gear wheel with internal teeth and a driven coupling half with gears installed therein that engage with the internal teeth of the driving coupling half, as well as elastic elements in the form of a plate pack associated with gears, gears are made with two radial grooves located at an angle to each other, and the ends of the elastic elements are fixed in the said grooves and together with the gears form a closed loop.

На фиг. 1 изображена предлагаемая упругая зубчатая муфта, продольный разрез, на фиг. 2 - сечение А-А на фиг. 1.In FIG. 1 shows the proposed elastic gear coupling, a longitudinal section, in FIG. 2 is a section AA in FIG. 1.

муфта содержит ведущую полумуфту 1 в виде зубчатого колеса 2 с внутренними зубьями, которое входит в зацепление с шестернями 3, установленными на осях 4, закрепленных в Ζ*’ ведомой полумуфте 5 равномерно по окружности диаметром т> и взаимодействуют с упругими элементами 6 в виде пакета упругих металлических и резиновых пластин. Это взаимодей25 ствие обеспечивается тем, что тестер ни снабжены радиальными пазами 7, расположенными под углом друг к другу, а упругие элементы своими концами 8 и 9 располагаются в этих ра30 диальных пазах и образуют совместно с шестернями замкнутый контур. Глубина 1ί радиальных пазов должна обеспечивать надежное удержание концов 8 и- 9 упругих элементов от выскакивания, а ширина С? должна быть несколько меньше толщины пакета упругих элементов для того, чтобы обеспечить беззазорный с некоторым предварительным натягом монтаж упругих элементов. С уменьшением расстояния Ь· между шестернями жесткость муфты увеличивается. Упругие элементы работают на сложный изгиб с одновременным относительным сдвигом металлических и резиновых пластин . Такая работа упругих элементов дает возможность получить несколько нелинейную характеристику включения муфты, что, в свою очередь дает возможность обеспечить максимальную упруго-демпфирующую способность муфты.the coupling contains a driving coupling half 1 in the form of a gear wheel 2 with internal teeth, which engages with gears 3 mounted on the axles 4, mounted in the Ζ * 'driven coupling half 5 uniformly around the circumference with a diameter of t> and interact with the elastic elements 6 in the form of a package elastic metal and rubber plates. This interaction is ensured by the fact that the tester is not equipped with radial grooves 7 located at an angle to each other, and elastic elements with their ends 8 and 9 are located in these radial grooves and form a closed loop together with gears. The depth 1ί of the radial grooves should ensure reliable retention of the ends 8 and 9 of the elastic elements from popping up, and the width C? should be slightly less than the thickness of the package of elastic elements in order to ensure the installation of elastic elements with some preload clearance. With decreasing distance b · between the gears, the stiffness of the coupling increases. Elastic elements work on complex bending with simultaneous relative shift of metal and rubber plates. Such work of the elastic elements makes it possible to obtain a somewhat non-linear characteristic of the inclusion of the coupling, which, in turn, makes it possible to provide maximum elastic-damping ability of the coupling.

При вращении ведущей полумуфты 1, она своими зубчатым колесом воздействует на шестерни 3, которые будучи, связанными упругими элементами и увлеченными во вращение, передают крутящий момент через их оси на ведомую полумуфту 5. При этом обе полумуфты Ьоединяются с некоторым относительным поворотом. После выключения муфты шестерни возвращаются в исходное по- 30 ложение под действием возвратной упругости упругих элементов.When the driving coupling half 1 rotates, it acts on gears 3 with its gear, which, being connected by elastic elements and carried away by rotation, transmit torque through their axis to the driven coupling half 5. In this case, both coupling halves L are connected with some relative rotation. After turning off the clutch, the gears return to their original position under the action of the return elasticity of the elastic elements.

Предлагаемая муфта является реверсивной, простой в изготовлении, надежной в работе, обладает повышенной нагрузочной и упруго-демпфирующей способностями и может найти при5 менение в технике.The proposed coupling is reversible, easy to manufacture, reliable in operation, has increased load and elastic-damping capabilities and can find application in technology.

Claims

The invention relates to mechanical engineering. The elastic cog coupling is known, containing a leading coupling half in the form of a gear wheel with internal teeth and a driven coupling half with mounted gears that engage with the internal teeth of the driving coupling half, as well as elastic elements in the form of a package of plates connected by with gears 1) However, the known coupling has insufficient load and elastically damping abilities, since the elastic elements are fixed at the end of the driven coupling half and have a cantilever loading from the cuts of the gears. The purpose of the invention is to increase the load and elastic damping capacity of the coupling. The goal is achieved by the fact that in an elastic gear coupling containing a drive coupling half in the form of a gear wheel with internal teeth and a driven coupling coupling with gears installed in it, meshing with the internal teeth of the driving coupling half, as well as elastic elements in the form of a package plates connected with gears, gears are made with two radial grooves arranged at an angle to each other, with the ends of the elastic elements fixed in the packed grooves and forming a closed loop together with the gears. In this case, the elastic elements can be made in the form of alternating metal and rubber plates. FIG. 1 depicts the proposed elastic camshaft coupling, longitudinal section; in fig. 2 is a section A-A in FIG. 1. The clutch contains the leading coupling half 1 in the form of a gear 2 with internal teeth, which engages with gears 3 mounted on axles 4 fixed in the driven coupling half 5 evenly around the circumference with a diameter) and interact with the elastic elements 6 in the form package of elastic metal and rubber plates. This interaction is ensured by the fact that the gears are provided with radial grooves 7, which are angled to each other, and the elastic elements with their ends 8 and 9 are located in these radial grooves and form together with the gear wheels a contour. The depth li of the radial grooves must ensure reliable retention of the ends 8 and -9 of the elastic elements from popping out, and the width b must be somewhat less than the thickness of the package of elastic elements in order to provide a backlash-free installation of elastic elements. With a decrease in the distance b between the gears, the stiffness of the coupling increases. Elastic elements work on complex izpib with simultaneous relative shift of metal and rubber plates. Such an operation of elastic elements makes it possible to obtain a somewhat nonlinear characteristic of the clutch engagement, which, in turn, makes it possible to ensure the maximum elastic-damping capacity of the clutch. When the driving half coupling 1 rotates, it with its gear wheel acts on the gears 3, which, being coupled by elastic elements and entrained in rotation, transmit a torque through their axes to the driven coupling half 5. At the same time, both coupling halfs combine with some relative rotation. After the clutch is turned off, the gears return to their original position under the action of the resilient elastic of the elastic elements. The proposed coupling is reversible, easy to manufacture, reliable in operation, has increased load and elastic-damping abilities and can be used in engineering. Claim 1.
