  • Patent number: 8161849
    Abstract: An adjustable torque limiter that can be coupled between a high speed driver and the socket that rotates a mechanical fastener. When a preset torque level is reached, the torque limiter disengages the rotational drive force from the bit. The adjustability of the torque limitation is accomplished by varying the amount of spring force by which a thrust plate (coupled to the high speed driver) is forced against a set of steel balls residing in slots of a radial torque plate and in a set of paths formed in a concavity of an upper torque body (coupled to the driven socket engaging stud). When a certain preset torque is transmitted from the driver to the socket, the steel balls traverse outward along the separate arced ramp radial paths therein the upper torque body until the balls enter an annular race that allows the thrust plate to go into a disengaged or free wheel mode from the upper torque body.
