STAND FOR TESTING MECHANICAL TRANSMISSIONS WHICH TRANSFORM ROTARY MOTION OF SCREW TO TRANSLATIONAL MOTION OF NUT Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: nut axial displacement drive 2, nut turn precluding assembly 3, axial force measuring device 4 with L-shaped pressure element 5 are hinge-connected to stand base 1. Transmission is positioned in body 6 hinge-joined to axial force measuring device 4 between basic assemblies 7 and 8. Drive 2 of nut axial displacement is also hinged to nut turn precluding assembly 3. Transmissions of different dimensions may be tested by means of stand. For this purpose body 6 is provided with groove along which basic assemblies 7 and 8 are moved during adjustment, and use is made of device which locks nut 9 in axial position. Stand allows performance of tests in motion and in statics. EFFECT: higher measurement accuracy. 6 cl, 5 dwg
