Abstract
Полезная модель относится к области машиностроения и может быть использована в конструкциях машин при неподвижных соединениях цилиндрических поверхностей валов (осей) со ступицами.Бесшпоночное соединение содержит вал с охватывающей его ступицей, выполненный с двух сторон с частичными осе-радиальными разрезами. При этом наружные поверхности ступицы выполнены с конусообразными формами с коническими резьбами, на которые навинчены гайки.Технический результат - снижение радиальных габаритов изделия металлоемкости, повышение работоспособности изделия. 1 ил.The invention relates to the field of mechanical engineering and can be used in machine designs with fixed joints of cylindrical surfaces of shafts (axles) with hubs. The keyless connection contains a shaft with a hub covering it, made on both sides with partial axial-radial cuts. In this case, the outer surfaces of the hub are made with conical shapes with tapered threads on which the nuts are screwed. The technical result is a reduction in the radial dimensions of the metal-intensive product, and an increase in the operability of the product. 1 ill.
Description
Полезная модель относится к области машиностроения, в частности к соединениям деталей машин типа вал-ступица, и может быть использована как начальное соединение деталей отдельных узлов машин, так и при восстановлении разрушенных соединений, например, шпоночных и др.The utility model relates to the field of mechanical engineering, in particular to the connection of machine parts of the shaft-hub type, and can be used both as the initial connection of parts of individual machine components, and in the restoration of broken joints, for example, keyways, etc.
Известно бесшпоночное соединение вала с цилиндрической опорной поверхностью со ступицей посредством винтового соединения - болта (Кудрявцев В.Н. Детали машин. // М.: Машиностроение, 1980. - Рис. 11.8, 6, стр. 194. Аналог).Known keyless connection of the shaft with a cylindrical bearing surface with the hub through a screw connection - a bolt (Kudryavtsev V.N. Machine parts. // M .: Mechanical Engineering, 1980. - Fig. 11.8, 6, p. 194. Analogue).
К недостаткам такого соединения деталей относятся увеличенные радиальные габариты, неравномерность обжатия ступицей вала в тангенциальном направлении.The disadvantages of such a connection of parts include increased radial dimensions, uneven compression of the shaft hub in the tangential direction.
По технической сущности в качестве прототипа принято бесшпоночное соединение, содержащее круглый вал с обхватывающей его ступицей, выполненной по ее концам с частичными осе-радиальными разрезами, а наружные поверхности конусообразной формы, на которых размещены диски с внутренними конусными поверхностями, стягиваемые между собой болтами через отверстия в диске ступицы (Патент на полезную модель РФ №188009 МПК F16D 1/06 Бюл. №13, 2019. Прототип).According to the technical essence, a keyless connection is adopted as a prototype, containing a round shaft with a hub wrapping around it, made at its ends with partial axial-radial cuts, and the outer surfaces are conical in shape, on which discs with internal conical surfaces are placed, bolted together by bolts through holes in the hub disk (Utility Model Patent of the Russian Federation No. 188009 IPC F16D 1/06 Bull. No. 13, 2019. Prototype).
Недостатки этого технического решения - значительные радиальные габариты, неравномерность радиального обжатия ступицы в тангенциальном направлении вследствие неравномерности затяжки отдельных болтов.The disadvantages of this technical solution are the significant radial dimensions, the unevenness of the radial compression of the hub in the tangential direction due to the uneven tightening of individual bolts.
Задачей изобретения является разработка конструкции соединения деталей типа вал-ступица, обеспечивающего при минимальных радиальных габаритах надежную работоспособность при легкой сборке и разборке, а также обеспечение возможности восстановления работоспособности разрушенных соединений вала со ступицей, например, шпоночных и др.The objective of the invention is to develop a design for connecting parts of the shaft-hub type, which ensures reliable performance with easy assembly and disassembly with minimal radial dimensions, as well as providing the ability to restore the functionality of broken shaft connections with the hub, for example, keyed and others.
Поставленная задача решается путем выполнения конусных поверхностей ступицы с коническими резьбами, а дисков в виде гаек с внутренними коническими резьбами, навинченных на конические резьбы конических поверхностей ступицы с задаваемым крутящим моментом.The problem is solved by performing the tapered surfaces of the hub with tapered threads, and disks in the form of nuts with internal tapered threads screwed onto the tapered threads of the tapered surfaces of the hub with a given torque.
На фиг. 1 представлен эскиз бесшпоночного соединения деталей фронтальною вида с осевым сечением.In FIG. 1 is a sketch of a keyless connection of parts of a frontal view with an axial section.
Бесшпоночные соединения деталей по фиг. 1 содержит вал 1 с цилиндрической поверхностью, на котором установлена ступица 2. имеющая с двух сторон частичные осе-радиальные разрезы 3. Наружные поверхности 4 ступицы 2 выполнены конусообразными с коническими резьбами 4, на которых навинчены гайки 5 с внутренними коническими резьбами.Keyless connections of the parts of FIG. 1 comprises a
Работа бесшпоночного соединения деталей.Keyless joining of parts.
После установки на вал 1 ступицы 2 на нее навинчиваются с двух сторон гайки 5, вследствие чего по сопрягаемым поверхностям вала и ступицы создается нормальное давление. При нагружении ступицы рабочей нагрузкой по сопрягаемым поверхностям создаются силы трения, передающие валу эту нагруженность.After installing the
В случаях разрушения шпоночного соединения вала со ступицей (или прессового и др.) представляется возможность восстанавливать работоспособность прежнего соединения путем создания на ступице перечисленных выше элементов и установки на прежнее место на валу без шпонки, при сохранении посадочных поверхностей сопрягаемых деталей.In cases of destruction of the key connection of the shaft with the hub (or press, etc.), it is possible to restore the former connection by creating the above elements on the hub and reinstalling it on the shaft without a key, while maintaining the seating surfaces of the mating parts.
