Description

Известны машины дл  испытани  подшипниковых материалов, содержащие установленный в опорных подшипниках рабочий вал с закрепленными ,на нем корпуса ми, в которых устанавливаютс  испытуемые образцы.Machines for testing bearing materials are known that contain an operating shaft mounted in support bearings with housings fixed on it, in which test specimens are mounted.

Предлагаемой машинной дл  испытани  подшипниковых материалов можно проводить испытани  в услови х трени  качени  и получать павышенную точность измерени  момента трени . Это достигаетс  тем, что корпуса выполнены са моустанавливаюшимис  с с приложением iK ним раст гиваюшего усили  в осевом направлении.The proposed machine for testing bearing materials can be tested under conditions of rolling friction and obtain a high precision measurement of the moment of friction. This is achieved by the fact that the housings are made self-assembled with the application of iK by a tension force in the axial direction.

Дл  увеличени  долговечности машины путем разгружени  опорных подшипников к ним приложены осевые усили  в противоположных друг другу наиравлени х.To increase the durability of the machine by unloading the bearings, axial forces are applied to them in opposite directions.

На фиг. 1 показана схема предлагаемой машины; на фиг. 2 - испытательна  голоека в разрезе.FIG. 1 shows the scheme of the proposed machine; in fig. 2 - test cutter in the cut.

На двух шарикоподшипниковых опорах 7 укреплен горизонтальный вал 2 с наборо.м шкивов 3. На обоих концах вала имеютс  самоустанавливаюшиес  корпуса испытательных головок 4 с образцами 5.A horizontal shaft 2 with a set of pulleys 3 is fastened on two ball bearing supports 7. At both ends of the shaft there are self-mounted cases of test heads 4 with samples 5.

Переменна  или посто нна  осева  нагрузка создаетс  программным устройством 6 и передаетс  через систему рычагов 7 и 5, тросVariable or constant axial load is created by software device 6 and transmitted through a system of levers 7 and 5, a cable

9 и крестообразный л есткий шарнир 10 на корпус головки 4, а затем через образе ц 5 на внутреннюю обойму конического роликоподшипника 11. Образец 5, выполненный в виде тотакого кольца с конической внутренней поверхностью , испытываетс  в паре со стандартным КОНИЧеОКИМ рОЛИК ОПОДШИПНИКОМ //,9 and a cruciform rigid hinge 10 on the head housing 4, and then through the image of q 5 on the inner race of a tapered roller bearing 11. Sample 5, made in the form of such a ring with a tapered inner surface, is tested in conjunction with a standard TIP ROLLER //,

роль наружного ,кольца которого выполн ет образец 5.the role of the outer ring of which sample 5 performs.
