Description
Изобретение относитс к области машиностроени и может найти применение при повышенных требовани х к точности кинематических цепей.The invention relates to the field of mechanical engineering and may find application with increased demands on the accuracy of kinematic chains.
Известны безлюфтовые шпоночные (шлицевые ) соединени с монтажной выборкой люфтов посредством клиновых или стопорных (упорных) элементов.Known backlash-free keyed (slotted) connections to the assembly selection of backlashes by means of wedge or locking (stop) elements.
Однако во многих конструкци х необходимо обеснечить безлюфтовое, но периодически подвижное соединение, а также эксплуатационную регулировку нат га в соединении, что особенно сложно при закрытых (недоступных ) соединени х.However, in many structures, it is necessary to deplete the backlash-free, but periodically mobile connection, as well as the operational adjustment of tension in the connection, which is especially difficult with closed (inaccessible) connections.
Дл упрощени экснлуатацин и повышени работоспособности соединение снабжено втулкой с торцовыми зубь ми, соединенной с валом шпонкой или шл.ицами и поджатой резьбовым элементом, например гайкой, а с колесом - с иомошью торцовых зубьев, вхо д щих в зацепление с торцовыми зубь ми, выполненными «а колесе, причем зубь втулки смещены относительно зубьев колеса на величину, меньшую лолювилы шага зубьев, обеспечива ири зат жке гайки взаимный разворот соедин емых деталей и выборку зазора в шпоночном или шлицевом соединении.In order to simplify the excluatacin and increase its working capacity, the joint is equipped with a socket with end teeth, connected to the shaft with a dowel or loop, and a threaded element pressed in, for example a nut, and with a wheel with a tooth of end teeth that engage with end teeth made “In the wheel, the bushing teeth are displaced relative to the wheel teeth by an amount less than the louvilles of the tooth pitch, ensuring that the nut is tied back with a mutual reversal of the parts to be joined and the gap in the keyway or spline joint is selected.
При торцовом (осевом) сжатии такого зубчатого зацеплени за счет клинового эффекта на взаимно смещенных и, следовательио , не полностью зацепленных зуоь х, происходит взаимный угловой разворот втулки п колеса и выборка зазора в щноиочном (шлнцевом ) соеднненин.At face (axial) compression of such gearing due to the wedge effect on mutually displaced and, consequently, not fully engaged teeth, a mutual angular rotation of the wheel hub and selection of the gap in the schnochichnoe (schlintsevom) connection occurs.
Сжатие и разжатие торцового зубчатого зацеплени и, следовательно, регулировка нат га или зазора в шионочиом (шлицевом) соединении осушествл ютс любым способом и, в первую очередь, с помощью тайки, расположенной в доступном месте на резьбовом хвостовике вала.The compression and decompression of the end gear and, consequently, the adjustment of the tension or clearance in the spline (spline) connection are carried out in any way and, primarily, with the help of a sling located in an accessible place on the threaded shaft end.
Иа чертеже изображено описываемое соедипение .The drawing shows the described connection.
Вал / соедин етс с зубчатым колесом 2 шпонкой 5. Па валу / и шпонке 3 установлена втулка 4. Па сонр женных торцах колеса и втулки выполнены остроконечные зубь 5, причем зубь на втулке смещены относительно зубьев на колесе на некоторую величину а, меньшую половины их шага.The shaft / is connected to the gear wheel 2 by the key 5. The shaft 4 and the key 3 are fitted with a sleeve 4. Pa of the end faces of the wheel and bushings are made with pointed teeth 5, with the teeth on the sleeve offset by less than half of the teeth on the wheel. steps.
Колесо и втулка ст гиваютс гайкой 6. При этом их торцовые зубь 5 зацепл ютс , и за счет взаимного смешени зубьев происходит взаимный разворот колеса и втулки на валу относительно шнонки (шлица) 3, что обеспечивает жесткий односторонний контакт колеса со шнонкой и надежное безлюфтовое соединение колеса и вала.The wheel and bushing are fastened with nut 6. At the same time, their end teeth 5 engage, and due to the mutual mixing of the teeth, the wheel and bushing on the shaft intertwine relative to the pivot (spline) 3, which ensures a hard one-sided contact of the wheel with the nail and reliable backlash wheels and shaft.
Дл осевого перемещени колеса вдоль вала гайка 6 отворачиваетс , и при этом вFor axial movement of the wheel along the shaft, the nut 6 is turned, and
шпоночном (шлицевом) соединении образуетс необходимый зазор.A key (spline) connection creates the necessary clearance.
Предмет изобретени Subject invention
Безлюфтовое шпоночное .или шлицевое соединение деталей, например, вала и зубчатого колеса, отличающеес тем, что, с целью упрощени эксплуатации и повышени работоопособност .и, оно снабжено втулкой с торцовыми зубь ми, соединенной с валом шпонкой .ил.и шлицами и поджатой резьбовым элементом , например, гайкой, а с колесом - с помошыо торцовых зубьев, вход ших в зацепление с торцовыми зубь ми, выполненными на колесе, причем зубь втулки смещены относительно зубьев колеса на величину, меньшую половины шага зубьев, обеспечива при зат жке гайки взаимный разворот соедин емых деталей и выборку зазора в шпоночном или шлицевом соединении.Backlash keyed or splined connection of parts, for example, a shaft and a gear wheel, characterized in that, in order to simplify operation and increase working capacity, it is equipped with a sleeve with end teeth, connected to the shaft with a key and splined and splined and threaded an element, for example, a nut, and with a wheel, using end teeth that engage with end teeth made on the wheel, the teeth of the hub being shifted relative to the teeth of the wheel by an amount less than half the tooth pitch, providing Menus mutual reversal of the joined parts and a gap in the sample keyway or splined connection.
