Abstract
An industrial emergency brake is disclosed in which the braking members are disengaged gradually from the brake disc or the like after detonation of an explosive component or electromagnetic de-energization by a stud in threaded engagement with the braking member, a thermally expandable wedging member interposed between a fixed support for the brake and an abutment such as a nut on the stud. An electrical resistor or a high frequency heater heats the wedging member and gradually disengages the braking member from the brake disc.
Claims10
A method for limited, gradual disengagement of a brake comprising a support, a brake member, and at least one braking member, resilient means urging the braking member towards said brake member, wherein said method comprises the steps of:
- attaching said braking member to a stud having an abutment thereon;
- interposing a thermally expandable wedging member between said support and said abutment;
- and
- heating said thermally expandable wedging member thereby disengaging said braking member gradually.
A brake comprising a support, at least one braking member, resilient means constantly urging said braking member towards a brake member, a stud attached to said braking member, and an abutment provided on said stud facing said support, wherein the improvement comprises a thermally expandable wedging member interposed between said support and said abutment on said stub, and heating means in heat transfer relationship with said thermally expandable wedging member for heating said thermally expandable wedging member and thereby applying traction to said stud for disengaging said braking member.
