SU109027A1 - Device for testing mechanisms and gears of rotational motion - Google Patents

Description

The device (.) For testing mechanisms and transmissions of rotational motion using a closed kinematic value, which is located on the engine / engine, in general, and the test mechanism is known.

The peculiarity of the proposed device is that in

An open kinematic chain is provided with a slip clutch designed for a loaded torque mechanism. This type of ... h1P- .tva provides airworthiness1 testing not only mehshzmov with a hard, but also with a non-rigid kinematic connection. For this, the gear ratio of gears, the input of Ш .ИХ to the kinematic chain, is chosen in such a way that when testing mechanisms with a rigid kit, the mathematical connection has an ectoma. Slip of the clutch, and when testing mechanisms with a non-rigid kinematic connection (friction variants, belt transfers, and so on. 11.) in the mu (}), those would take place H: o.;

The advantage of the proposed device over the known devices with a closed kinematic chain without a clutch is the ability to initiate testing of mechanisms with both rigid and not / cinematic connection between the input and output shafts.

When testing mechanisms with a hard cinematic linkage, the transmission gear of the gears, the input and kinematic value, is chosen so that there is a shortening of the coupling, the BaioHiee gear, its stable operation and the transmission of a predetermined steep moment. With the same iexaism with a non-rigid inmatic link, the gear ratio is chosen so that the place is located in (1) those 11/15/11.e possible co .1-1ie ECO.
