Abstract

The invention relates to mechanical engineering. The aim of the invention is to increase the effectiveness of the tests by expanding the types of loading and simplifying the creation of loads. The shafts 6 and 7 of the tested gear 8 are installed in supports 2 and 3 and turned into one or opposite sides with the help of hydraulic cylinders 11 and 12, which, together with the oscillatory torque generated by the vibrator, creates a load on the teeth of the wheels of a given level and loading asymmetry. 2 Il.

Description

This invention relates to mechanical engineering.

The purpose of the invention is to increase the efficiency of testing by expanding stress types and simplifying load generation.

Fig. I shows a schematic diagram of the stand t, lh test of the gears; Fig 2 - view A in Fig 1

The bench for testing differential gears contains a base 1 with supports 2 and 3, in bearings 4 and 5 of which the first 6 and second 7 shafts of the tested differential gear 8 are placed. Levers 9 and 10 are rigidly attached to the shafts 6 and 7, the free ends of which by means of hydraulic cylinders 11 and 12 IKVXC mpoiuii i о; ki i vi with in foam with oi Izhas mnem 1 Hydrocystics 11 and 12 with hydromagnets through the distributor are connected to an overpressure source (not shown) The third shaft 13 is connected by means of no. 14, eg torsion shaft, with lever 15, rigidly fixed on the case of the ui4n 8 trunk The lever 15 by means of pimenta 1 6 is spring-loaded to the base I The lever 15 is set to create a cyclic load on it made in the form of a vibrator 17, one of which is connected to j, ecgrOi1 atomic .tem 14, nmechmshp1 p google i'm um n pgog time. rotor scenes
