Defining parameters of elastic-safety clutches for screw conveyers
Journal Title: Вісник Тернопільського національного технічного університету - Year 2017, Vol 87, Issue 3
Abstract
The designs of elastic-safety clutches of screw conveyors are offered allowing, except safety conditions, due to damping and elastic properties to ensure smooth start of conveyor screw while in drive run-up and reduce the sharpness of changes in load on it during operation and overloading. The analytical dependence of the determination of impact loads with axial and torque shocks in the investigated clutch at the boundary moment of its actuation is given. The graphical dependences of the change in the torque value depending on the movement of the movable half-clutch in the mode of protection device actuation at different angle of the hitch inclination are shown.
