Однако это устройство требует обя-10 зательной эксцентричной проточки и связано с необходимостью иметь уступ на валу для осевой фиксации ступицы.However, this device requires obya- optionally eccentric bore 10 and connected with the need to have a shoulder on the shaft for axial locking of the hub.

Наиболее близким к предлагаемому по технической сущности и достигав-, мому результату является торцовое крепление ступицы к валу при помощи шайбы, установленной в кольцевой проточке, выполненной на внутренней поверхности ступицы, и болта, размещенного в центральном резьбовом отверстии вала и в эксцентричном отверстии шайбы £27Closest to the proposed technical essence and achieved, my result is a face mount hub to the shaft with a washer installed in the annular groove made on the inner surface of the hub and a bolt placed in the central threaded hole of the shaft and eccentric washer hole £ 27

Однако известное устройство требует обязательного наличия уступа на валу и, как правило, шпонки, что усложняет конструкцию и технологию изготовления соединения и не обеспечивает надежность соединения ступицы с валом.However, the known device requires the obligatory presence of a step on the shaft and, as a rule, keys, which complicates the design and manufacturing technology of the connection and does not ensure the reliability of the connection of the hub with the shaft.

Цель изобретения - повышение надежности соединения путем обеспечения более жесткой фиксации ступицы относительно вала в осевом и радиальном направлениях. Поставленная цель достигается тем. что в торцовом соединении вала со ступицей, содержащем элемент фиксации в окружном направлении и болт для осевой фиксации ступицы относительно вала, элемент фиксации в окружном направлении выполнен в виде.разрезной втулки с конической внутренней поверхностью, а болт выполнен с коническим участком и установлен эксцентрично оси вала с возможностью 'The purpose of the invention is to improve the reliability of the connection by providing a more rigid fixation of the hub relative to the shaft in the axial and radial directions. This goal is achieved by. that in the face connection of the shaft with a hub containing a fixation element in the circumferential direction and a bolt for axial fixation of the hub relative to the shaft, the fixation element in the circumferential direction is made in the form of a split sleeve with a conical inner surface, and the bolt is made with a conical section and is set eccentrically to the axis of the shaft with an opportunity '

На фиг. 1 изображено крепление ступицы к валу с помощью болта с головкой под накидной ключ, продольный 5 разрез; на фиг. 2 - вид А на фиг. 1; на фиг. 3 - устройство с болтом, имеющим гнездо под торцовый ключ, продольный разрез.FIG. 1 shows the attachment of the hub to the shaft using a cap wrench, longitudinal section 5 ; in fig. 2 is a view A of FIG. one; in fig. 3 - device with a bolt having a socket for a socket wrench, longitudinal section.

Торцовое соединение вала со сту- ю пйцей содержит ступицу 1, установленную на конце вала 2. На торце ступицы выполнена кольцевая канавка 3, в которой установлена шайба 4 с продольным разрезом 5 и с внутренней ,5 конической поверхностью 6.The face joint of the shaft with the stem with a finger contains a hub 1 mounted on the end of the shaft 2. At the end of the hub there is an annular groove 3 in which the washer 4 is installed with a longitudinal section 5 and with an inner, 5 conical surface 6.

В эксцентричном относительно оси вала 2 резьбовом отверстии 7 установлен болт 8 с коническим участком 9, сопрягаемый с конической поверх- 20 ностью 6 шайбы 4. Болт 8 снабжен либо головкой 10 (фиг. 1) либо гнездом 11 под ключ (фиг. 3)·In the screw hole 7 eccentric relative to the shaft axis 2, a bolt 8 with a conical section 9 is fitted, mating with a conical surface 6 of the washer 4. The bolt 8 is equipped with either a head 10 (Fig. 1) or a turnkey socket 11 (Fig. 3) ·

Торцовое крепление ступицы к валу осуществляется следующим образом. 25Face fastening of the hub to the shaft as follows. 25

На вал 2 устанавливается деталь (шестерня, полумуфта и т.п.) со ступицей 1. В проточку 3 заводится шайба 4, после чего болт 8 взаимодействует с конической поверхностью 6 30A part (gear, half coupling, etc.) is mounted on the shaft 2 with a hub 1. A washer 4 is inserted into the groove 3, after which the bolt 8 interacts with the conical surface 6 30

шайбы 4, заставляя последнюю (расширяться за счет имеющегося продольного разреза 5 и прижиматься своей наружной цилиндрической периферийной поверхностью к поверхности проточки 3, так как ось конической поверхности 6 шайбы смещена относительно осиwashers 4, forcing the latter (to expand due to the existing longitudinal section 5 and press its outer cylindrical peripheral surface to the surface of the groove 3, since the axis of the conical surface 6 of the washer is offset relative to the axis

проточки на ту же величину эксцентриситета что и ось болта 8 относительно оси вала. Разборка производится в обратной последовательности.grooves on the same amount of eccentricity as the axis of the bolt 8 relative to the axis of the shaft. Disassembly is performed in reverse order.

Применение предлагаемого изобретения позволит повысить надежность крепления, а также упростить конструкцию вала и повысить технологичность изготовления ступицы.The application of the present invention will improve the reliability of fastening, as well as to simplify the design of the shaft and improve the manufacturability of the hub.
