Gear mounting

A gear mounting having a spindle extending substantially normal to a carrier and capable of radial excursions from an initial position, when under load, characterised in that the spindle and carrier have generally frusto-conical abutment surfaces, normals to which extend substantially through the centroid of a projecting portion of the spindle and in that in the initial position of the spindle there is a gap between the abutment surfaces, said gap being sufficiently dimensioned to allow the spindle to be stressed in bending only up to a pre-determined load, such that when the pre-determined load is reached or exceeded, the abutment surfaces will engage to generate a reaction load whereby the spindle is stressed in tension and bending.
