GEAR FOR COMBINED TESTING OF OBJECTS Russian patent published in 1994 - IPC

FIELD: radio electronics. SUBSTANCE: cylindrical adapter 2 which upper butt carries tested radio electronic article 3 is attached to table of vibration exciter 1. Rubber diaphragm 4 is put over circumference of side surface of adapter. It is fabricated in the form of ring and is attached with its outer circumference to hole of immobile cylindrical chamber 5 located in its lower part. Upper part of cylindrical chamber has opening which can be matched with openings of thermal low-temperature chamber 6 and thermal high-temperature chamber 7 of movement mechanism. Decreased or increased temperature is fed into chambers over flexible hoses. Movement mechanism is manufactured in the form of segment structure. Teeth are cut in its outer surface which engage wheel mounted on shaft of reversible motor. When/it operates change of chambers takes place above opening of cylindrical chamber and consequently change of temperature in it. EFFECT: increased efficiency of testing of radio electronic articles for resistance to effects of mechanical and climatic factors. 3 dwg
