ABSTRACT:
An overload coupling includes two portions that are relatively rotatable about a common axis upon overload. During operation, the driving portion turns the driven portion through one or more shear pins that are closely fitted in the same or a respective cutting element. In one version, the two portions have aligned sleeves that hold a common shear pin. The sleeves and pins can be readily exchanged for those able to transmit greater or lesser torque. Also, there can be two or more pins held in the aligned sleeves and offset from the sleeves' center line for adjustment. In another version, one portion can mount groups of pins, one of which fits into a recess between two cylindrical cutting elements. The elements have different sized cavities to closely bear on one pin until shear. After shear, the driving portion r.p.m. is reduced or stopped until another pin or portion is urged into the recess. Different sized pins can be used and each element rotated to expose the correct cavity. Either element engages the pin depending on direction of rotation.
