FIELD: instrumentation.
SUBSTANCE: invention relates to torque meters. Proposed device comprises bed with two struts secured thereto to retain the plate with ball bearing fitted therein. Stepped roll is arranged at inner ring to turn thereabout for controlled torque to be applied to its top step. L-like lever is arranged at roll lower step end. Right parts of the main and extra resilient plates are attached to said lever while left parts are secured to aforesaid strut. Measuring nozzle arranged perpendicular to the main plate and with clearance therewith in the device strut hole. Said nozzle is communicated via unions and air ducts with inner surface of bellows in air chamber located at one of said struts. Said bellows is attached by one end to support plate and by another tightly closed end contacts with moving leg of dial indicator. Angle piece with adjusting bolt and lock nut is secured ay said support plate. Clearance is maintained between angle piece ends and air chamber outlet channel connected with bellows outer surface.
EFFECT: more stable working cycle.
