<p>A torque limiting device in accordance with the present invention comprises first and second relatively rotatable elements (38, 39), the first element (38) being hollow and receiving the second element (39) therein, the outer periphery of the second element (39), and/or the inner periphery of the first element (38) being of non-circular cross-section so that the radial dimension of a gap defined between the outer periphery of the second element and the inner periphery of the first element is not constant during relative angular movement of the elements, the device further including an elastic component (41) in said gap between said first and second elements, the, or at least one of the, non-circular peripheries being slidable relative to said elastic component (41) whereby said elastic component is deformed during relative angular movement of the first and second elements (38, 39) and so resists said relative angular movement. The invention further resides in a starter motor incorporating such a torque limiting device so as to limit torque transfer between the armature of the starter motor and the pinion gear of the starter motor.</p> |
