Product Summary

The endless screw, comprising a series of thin ceramic plates which are fixed next to one another at the outer edge of the screw, characterized in that at least two formed ceramic projections, particularly ceramic pins, protrude from the thin ceramic plates and are arranged in one or two lateral faces of the edge of the screw, i.e. in recesses which are profiled according to the protrusions or pins.

A endless screw and method for preventing stick-slip friction conditions from exciting the endless screw into surging and for preventing surging vibration from adversely affecting operation of the conveyor. The endless screw has a pair of endless, flexible roller chains that are laterally spaced apart and carried on sprockets keyed to a drive shaft that is in communication with a drive at one end of the frame and sprockets keyed to a take-up shaft at the opposite end of the frame.

The endless screw components are selected to provide a combination of chain stiffness and endless screw mass moment of inertia at maximum payload that produces a conveyor having a high enough natural frequency to prevent stick-slip friction conditions from exciting the conveyor chains into surging. Should a endless screw possess a natural frequency falling within the range of natural frequencies causing the endless screw to be susceptible to surging, a dampener that includes a flywheel disc coupled to the endless screw take-up shaft by a spring is attached to one or preferably both ends of the take-up shaft of the conveyor for preventing stick-slip from exciting the conveyor chains into surging and reducing the amplitude of any surging vibrations which might occur so they do not adversely affect operation of the endless screw.
