<p>A drive torque limiter comprises a wheel-shaped driving member (18) having a center hole (34) which is sized for a substantial slip fit over a driven shaft (36). A friction plate (38) is located on at least one side of the driving member; the friction plate (38) rotates without slippage with the shaft (36,40). Locking means (44,46) are provided for preventing the driving member and the friction plate from sliding longitudinally on the shaft. A spring (48) biases the driven member and the friction plate together. An annular-ring surface (50) is located on the friction plate (38) or the driving member (18) or both. The annular-ring surface is substantially concentric with the driven shaft (36,40) and forms an annular-ring interface between the friction plate and the driving member. The transmitted torque between the driving member and the driven shaft is limited by frictional force between the friction plate and the driving member at the annular-ring interface.</p> |
