The Theoretical Analysis of Chain Drive System for Heavy Duty Apron Feeder

Abstract:

Taking a certain type of heavy duty apron feeder inmobile crushing station as the object of study, this paper proposed a five-barmechanism to research the velocity fluctuation problems of chain drive systemin an apron feeder. The effects of impulsive loads were analyzed, and amechanics model of meshing area was proposed. The research results are asfollows. 1. In the conveying direction, the number of teeth and sprocket pitch hasthe most influential effect on the vibration. 2. External impulsive loads causea significant increment of chain force, in particular the loads caused by largematerials. 3. The teeth and rollers near the tight-side chain play a major rolein transferring the torque, and the initial pressure angle affects their stressconditions immensely.
