Description

Изобретение относитс к области машиностроени .The invention relates to the field of engineering.

Известен стенд дл испытани зубчатых соединений, содержащий два редуктора , установленных на станине с 5 возможностью поворота вокруг оси при- вода и св занных друг с другом двум кинематическими, цеп ми, перва из которых имеет карданный вал, а втора испытываеьМе объекты. 10A stand for testing gearing is known, containing two gears mounted on a frame with 5 rotatables around the axis of the drive and connected to each other by two kinematic chains, the first of which has a propeller shaft and the second objects to be tested. ten

На таком стенде нельз воспроизвести услови работы зубчатых соединений типа вал-вал.On such a bench, it is impossible to reproduce the operating conditions of the shaft-shaft type gear joints.

Целью изобретени вл етс расширение технологических возмож- 5 ностей стенда.The aim of the invention is to expand the technological capabilities of the stand.

Поставленна цель достигаетс тем, что втора кинематическа цепь выполнена в виде двух расположенных 20 соосно дополнительных редукторов и- установленного в опоре вала, испытываемые объекты размещены между каждым дополнительным редуктором и валом и соединены с ними, причем на ста- 25 Нине выполнены взаимно перпендикул рные пазы, в которых установлены дополнительные редукторы и опора. На чертеже показан предлагаемый .стенд..30The goal is achieved by the fact that the second kinematic chain is made in the form of two additional gears arranged coaxially and mounted in the shaft support, the test objects are placed between each additional gearbox and the shaft and connected to them, with mutually perpendicular grooves on the 25 Nina in which additional gearboxes and support are installed. The drawing shows the proposed. Stand ..30

Стенд дл испытани зубчатых соединений состоит из двух балансирно подвижных на- станине 1 редукторов 2 и 3, которые могут свободно проворачиватьс вокруг оси 4 привода 5. Редукторы 2 и 3 св заны друг с другом двум кинематическими цeп мIi. Перва кинематическа цепь имеет карданный вал б, соедкн кщий выходные валы 7 и 8 редукторов 2 и 3 с помощью карданных шарниров 9 и 10, совмещенных с нагружающими полумуфтами 11 и 12. Втора кинематическа цепь состоит из двух соосно установленных дополнительных редукторов 13 и 14. Между ними находитс опора 15 с валом 16. Выходные валы 17 и 18 дополнительных редукторов 13, 14 и вал 16 опоры 15 соединены испытываемыми объектами 19 и 20, например шлицевыми втулк.ами .The test bench for gearing consists of two balancingly movable stand 1 gearboxes 2 and 3, which can freely rotate around axis 4 of the drive 5. Gearboxes 2 and 3 are connected to each other by two kIematic mIi chains. The first kinematic chain has a cardan shaft b, connecting output shafts 7 and 8 of gearboxes 2 and 3 with cardan joints 9 and 10, combined with loading coupling halves 11 and 12. The second kinematic chain consists of two coaxially mounted additional gearboxes 13 and 14. Between there is a support 15 with a shaft 16. The output shafts 17 and 18 of additional gearboxes 13, 14 and the shaft 16 of the support 15 are connected by test objects 19 and 20, for example spline bushings.

Claims

Additional gears 13, 14 and support 15 are mounted in the slots of the frame 1 and can be moved along them. Moving additional gears 13 and 14 allows you to set test objects 19 and 20. The groove through which support 15 moves is perpendicular to the grooves for additional gears 13 and 14. By discharging support 15, the misalignment of the test objects of the gear connection is necessary. On the gearbox 2 fixed lever 21 with a load. The stand works as follows. The test objects 19, 20 and the required torque are preliminarily set by relative twisting of the shafts with the coupling halves 11 and 12 open. When the shafts are twisted, one of the coupling halves locks to the frame, and the second coupling half rotates through a certain angle using the lever 21. When In this way, the gearbox 2 with the load on the lever 21 rotates around the axis 4. With the rigid coupling of the coupling halves 11 and 12, the kinematic chains turn out to be statically loaded with the required twisting link that creates a suspension of gear / gear. at 21, installed with a particular lane CPCE th vj n.ahruzhennye desired steep:;. oientom .ispytyvaemye samples at pas; 5oto, the stand are subjected to wear. When the teeth of the specimens wear out, the reductor 2 with the load gradually lowers, indicating the magnitude of the total wear of the specimens. Formula of the Invention A test stand for toothed joints - containing two gear units mounted on. The frame can be rotated around the axis of the drive and connected with each other by two kinematic chains, the first of which has a propeller shaft, and the second test objects are about. that; with a chain of technological expansion, the second kinematic chain is made. in the form of two coaxially arranged additional gearboxes and a shaft installed in the bearing, the test objects are placed between each additional gearbox and the shaft and are connected to them, and the frame is mutually perpendicular to the axes, in which the additional gearboxes and the support are installed .
