  • Disk brake for elevator drive
    Patent number: 6520299
    Abstract: An elevator drive includes a casing with a shaft supported by spaced shaft bearings. Arranged on the shaft between the bearings are a traction sheave and a brake disk. On a free end of the shaft is a motor ventilated by fans. Arranged on the casing is a symmetrically constructed braking device with two single-arm brake levers having brake linings which, when braking occurs, press against the traction sheave and bring it to a standstill. Provided on a free end of each brake lever is a compression spring that is supported at one end on the brake lever and on the other end on a spring pin. The spring force of the compression spring acts on the brake lever thereby causing the brake lining to press against the traction sheave. To release the brake lever, a brake magnet provided with an armature plate is arranged on a brake lever, the brake magnet and the armature plate acting against the force of the compression springs.
