Изобретение относитс к машино-строению , а именно к испытательной технике, и может быть- использовано в стендах дл испытани передач дл соединени СООСНЫХ валов узлов и агре- 5 гатов. The invention relates to a machine-building, in particular to testing equipment, and can be used in test stands for testing gears for connecting MUX shaft assemblies of units and aggregates.

Известно устройство дл соединени СООСНЫХ валов агрегатов стендов,содержащее опору,шлицевую втулку,один конец которой предназначен дл соеди-tO нени с валом одного из агрегатов, ползун и фиксатор p-j.A device is known for connecting the coaxial shafts of stand assemblies, comprising a support, a splined hub, one end of which is intended to connect to the shaft of one of the aggregates, a slider and a clamp p-j.

Недостаток известного устройства заключаетс в том,что соединение валов необходимо осуществл ть вручную, |5 а их соединение не обеспечивает необходимой виброизол ции друг от друга .A disadvantage of the known device is that the connection of the shafts must be carried out manually, and their connection does not provide the necessary vibration isolation from each other.

Цель изобретени - автоматическое соединение валов при условии из виб- 20 роизол ции.The purpose of the invention is to automatically connect the shafts under the condition of vibration isolation.

Цель достигаетс тем, что устройство снабжено предназначенной дл присоединени к валу другого агрега,та упругой муфтой, св занной с дру- 25 гим концом ишицевой втулки, и гидроцилиндром , взаимодействующим с опорой , выполненной в виде вилки, охватывающей ползун, последний размещен на втулке с возможностью перемещени 30The goal is achieved by the fact that the device is equipped with another aggregre, which is intended to be connected to the shaft, that elastic coupling connected to the other end of the bushing bushing, and a hydraulic cylinder that interacts with the support made in the form of a fork spanning the slider, the latter being placed on the bushing with moveable 30

вдоль нее, на наружной поверхности втулки выполнен винтовой паз, в- котором расположен фиксатор, св зывающий ползун с втулкой .Along it, on the outer surface of the sleeve, there is a screw groove, in which is a retainer connecting the slider with the sleeve.

На чертеже схематически изобреикено устройство дл автоматического со-единени валов агрегатов стенда.In the drawing, an apparatus for automatically connecting the shafts of the stand aggregates is schematically invented.

Устройство состоит из упругой муфты 1, св занной своим валом 2 с одним концом шлицевой втулки 3, выполненной с винтовым пазом 4. Ползун 5 установлен на втулке 3 и св зан с ней фиксатором 6, размещенным в винтовом пазу 4. Гндроцилиндр 7 св зан с вилкой 8, охватывамщей ползун 5. Вилка 8, вл юща с опорой всего устройства , установлена в профильной направл ющей 9. Муфта 1 предназначена дл соединени с вашом агрегата 10, а другой конец втулки 3 - дл соединени с шлицевым валом агрегата 11.The device consists of an elastic coupling 1 connected by its shaft 2 to one end of a splined sleeve 3, made with a screw groove 4. The slider 5 is mounted on the sleeve 3 and connected with it by a clamp 6 placed in a screw groove 4. Hydrocylinder 7 is connected plug 8, covering the slider 5. Plug 8, which is the support of the entire device, is installed in the profile guide 9. Coupling 1 is designed to connect to your unit 10, and the other end of sleeve 3 to connect to the splined shaft of the unit 11.

Устройство работает следующимThe device works as follows.

образом.in a way.

К валу агрегата 10 крепитс упруга муфта 1. Дл соединени с валом агрегата 1 срабатывает гидроцилиндрA flexible coupling 1 is attached to the shaft of the unit 10. A hydraulic cylinder operates for connection to the shaft of the unit 1

7и вилкой 8 перемещает шлицевую втулку 3 по пазам вала 2 упругой муфты 1 до касани с валом агрегата 11.7 and fork 8 moves the spline sleeve 3 along the grooves of the shaft 2 of the elastic coupling 1 until it touches the shaft of the unit 11.

Claims

The case of misalignment of the splines of the sleeve 3 and the shaft of the unit 11 slider 5, as a result of the interaction of the retainer 6 with the screw groove 4, rotates the sleeve 3 until the splines coincide with the splines of the shaft of the unit 11. unit 11 as far as it will go, providing the shaft lines of units 11 and 10 are driven. Upon further movement, the fork 8 is lowered and out of the connection with the slider 5 due to the profile guide 9. To disconnect the shaft of units 10 and 11, change the direction of movement of the hydraulic cylinder rod 7. The fork 8, moving along the profile guide 9, rises and engages in the slider 5, which moves along the splines of the shaft 2 of the coupling 1 of the sleeve 3 until it leaves the connection with the shaft of the unit C. Using the device of the elastic coupling and the actuator as hydraulic cylinders and cylinders,) provides for the automatic connection of coaxial shafts of the stand aggregates under the condition of Hk vibration isolation. Apparatus of the invention for connecting coaxial shafts of stand assemblies comprising a support, a splined hub, one end of which is designed to connect to the shaft of one of the assemblies, a slide and a locking device, which is different from the fact that, U the purpose of automatically connecting the shafts provided vibration isolation, it is provided with an elastic coupling intended for connection to the shaft of the other unit, connected to the other end of the splined hub, and a hydraulic cylinder that interacts with the support, made in the form of a fork, covering the slider, last a- placed on the sleeve so that it can move along it, on the outer surface of the sleeve. A screw groove is provided in which a retainer is located connecting the half-horn with the sleeve. Sources of information taken into account in the examination 1.
