Impact torque absorber

Abstract

Abstract PURPOSE:To absorb impact torque in an effective manner, by setting up a hermetically sealed chamber being full of fluid between two relatively rotatable rotary shafts and absorbing the relative angle displacement of these rotary shafts, while making up both shafts so as to link up with each other when said relative angle displacement is beyond the prescribed value. CONSTITUTION:A hermetically sealed chamber 6 being full of fluid is set up between the first rotary shaft 2 and the second rotary shaft 3 and divided into four small chambers 21, 22, 23, and 24 which are sectioned by vanes 13, 14, 17 and 18 and interconnected through flow passages 15, 16, 19 and 20 lying between respective vanes. And, when relative angle displacement happens between both rotary shafts 2 and 3, fluid moves at intervals between said small chambers 21-24 via flow passages 15 through 20 and if the relative angle displacement exceeds the prescribed value, these vanes 13, 18, 14 and 17 of both rotary shafts 2 and 3 are so made up that they are linked with each other and mechanically coupled together. With this constitution, all sizes of impact torque can be effectively absorbed without impairing the transmission efficiency of driving force.
