Изобретение относитс к машиностроению , в частности к стендам дл . испытаний муфт сцеплени .The invention relates to mechanical engineering, in particular to stands for. clutch testing.

Известны стенды дл испытани (Йэйкционных муфт, содержавшие привод с входным валом, на котором устанавливаетс испытуема муфтгг, закрепленн .а на .валу ведущей полумуфтой, а ведома кинематически, например через гибкую передачу, соединена с выходным .валом, имеющем последовательно установленные-на нем маховик и тормоз 1 .The test stands are known (the coupling couplings containing the drive with the input shaft on which the test coupling is mounted, fixed to the shaft with a leading coupling half, and driven kinematically, for example through a flexible gear, connected to the output shaft having series-installed flywheel and brake 1.

Недостатком стенда вл етс относительно мала производительность и недостаточна достоверность испытаний вследствие отсутстви сопоставимости результатов.испытаний, вызванных невозможностью их проведени одновременно в одинаковых услови х нескольких муфт и кроме того, при этом нет. возможности регулировать нагру зку. .The disadvantage of the bench is relatively low productivity and insufficient reliability of the tests due to the lack of comparability of the results. The tests caused by the impossibility of carrying out them simultaneously under the same conditions of several couplings and moreover, at the same time do not. opportunities to regulate the load. .

Цель изобретени - устранение эти недостатков, повышение ПРОИЗВО.ЦИтельности обеспечение возможности изменени нагрузки в процессе испытаний , а также повышение точности результатов испытаний путём сопоставлени данных по нескол ким муфтамThe purpose of the invention is to eliminate these disadvantages, to increase the SPEED. The ability to change the load during the testing process, as well as to improve the accuracy of the test results by comparing the data on several couplings.

Указанна цель достигаетс тем, что стенд снабжен промежуточным валом , соединенным с выходным валом зубчатыми, передачами с разными передаточными отношени ми, шестерни которыхна выходном валу установлены свободно и взаимодействуют с двухсторонними сцепными муфтами так, что включена может быть только одна пара зубчатых передач, а на входном валу устанавливаетс несколько исгйлтуемых .муфт, св занных с промежуточным валом .при помощи зубчатых Передач с оди наковЫм передаточным отношением.This goal is achieved by the fact that the stand is equipped with an intermediate shaft, gears connected to the output shaft, gears with different gear ratios, the gears of which are mounted on the output shaft freely and interact with two-way clutches so that only one pair of gears can be engaged, and The input shaft is fitted with several adjustable coupling coupled to the intermediate shaft using gears with the same gear ratio.

На чертеже изображена предлагаема муфта.The drawing shows the proposed coupling.

Несколько испытуемых фрикционных муфт 1 закрепл ютс ведущими полумуфтами на входном валу 2, св занные с приводом 3, а ведомые полумуфты 1 св заны с промежуточным валом 4 при помощи зубчатых передач 5 с одинаковым передаточным отношением. Промежуточный вал 4 соединен с выходным валом 6 зубчатыми передачами 7, 8,-,9 и 10 с разными передаточными отношени ми , при этом шестерни этих передач на выходном валу установл;ены свободно и взаимодействуют с двухстоSeveral test friction clutches 1 are fixed by driving coupling halves on the input shaft 2 connected to drive 3, and the driven coupling half 1 is connected to intermediate shaft 4 by gears 5 with the same gear ratio. The intermediate shaft 4 is connected to the output shaft 6 by gears 7, 8, -, 9 and 10 with different gear ratios, while the gears of these gears on the output shaft are set freely and interact with two

The stand operates as follows. Several test cases of clutches 1 are installed on shaft 2, start the drive motor 3 and include one of the tested couplings 1 in sineppen, then using o; n; of mu4) t 12 clutches impart rotation to the output shaft b, and with it mahivik 13. After a certain interim-ok time, the system of automatic control of the stand (not shown in the drawing - turns on one of the THaBaevbix F-thru clutches. Due to strength training and the driving drums of the training coupling take place; the flywheel 13. After the alignment of the angular velocities of the driving and driving friction disks, i.e. after synchronization, the automatic control system of the bench turns off the friction clutch and the drive: there is a brake The device 14, which then makes a complete stop at the flywheel 13. The switch with the single friction clutch is made in the same post sequence. Gears 5 with the same gear ratio provides for all tested friction clutches the same moment of inertia for each of the working positions of gear couplings 11 or 12, since sequential connection of all tested friction clutches will allow to make ONE: temporary test on the stand of several friction clutches under the same conditions, which allows reducing the time of the test and the most difficult to test, and most importantly get th dostoveryost and consistency of test results and the possibility of varying the load friction clutches without changing the moment of inertia of the inertial mass. In addition to this, the proposed stand construction relieves the loading of all Original Friction Couplings using a single inertial Mass. : Claims of the Invention Stand for testing the friction clutches containing the drive With an introductory wibm, the test-benches are mounted on the test-tube couplings, kinematically connected to the outlet cable, having a sequential yachrvik and a brake, and a liter and h and h. by the fact that / in order to improve the performance and make it possible to change the load in the process of testing, as well as to improve the accuracy of the test results by comparing data on several couplings, it is equipped with an intermediate shaft connected to the output shaft gears with different gear ratios, the gears of which are installed freely on the output shaft and interact with two-way couplings so that there can be only one, a pair of gears, and several test couplings connected to the intermediate shaft are mounted on the output shaft assistance gears with the same gear ratio.
