SU1716384A1 - Friction machine - Google Patents

Abstract

This invention relates to a testing technique. The purpose of the invention is to approximate the conditions tested and to the actual conditions of operation of the friction pairs operating in the mode of alternating relative displacement and rest. The disk 9 is fixed on a constantly rotating sleeve 6. A coupling coupling half 7 is attached to the lower part of the latter. A second coupling half 13 is applied movably on a spline shaft 11 mounted coaxially to the sleeve 6. The coupling coupling half and 7, i.e. Turning on and off the rotation of the sample is carried out with the help of levers 14 and 23 from the rotating cam. 4 sludge.

Claims (1)

Claim A friction machine comprising a housing, a counter sample holder installed therein, a drive for rotating it, a sample holder and a loading unit thereof, characterized in. that, in order to approximate the test conditions to the actual operating conditions of the friction pairs operating in the mode of alternating relative displacement and rest, it is equipped. rigidly connected to the sample holder by a shaft, the axis of which coincides with the axis of rotation of the sample and counter sample holders, a clutch, one coupling half of which is rigidly connected to the sample holder, the other is coaxially mounted on the shaft with the possibility of movement along it, connected to the rotation drive by a cam, the working surface of which kinematically connected with another coupling half, and a shoe kinematically connected with another coupling half · and intended for periodic interaction with the sample holder. figure 2 Fig 4
