DRAW WORKS BAND SHOE BRAKE WITH EQUALLY LOADED BANDS Russian patent published in 2017 - IPC F16D49/08 F16D65/04 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in draw works band shoe brakes. Draw works band shoe brake with equally loaded bands comprises brake pulley on shaft and equally loaded brake bands with serial friction pads and brake control drive. Brake bands leading edges are attached to crankshaft crank pins, and running ends are to rocking beam. Each equally loaded brake band is made composite and contains such parts as: ends with eyes and band sections on leading and trailing branches side, and band leading and trailing branches themselves. To band leading and trailing branches ends, starting from leading branch side fastening resilient elements with different rigidities are molded-on, which decrease towards band trailing end and are smaller than band branches rigidities.

EFFECT: enabling brake band leading and trailing branches unloading from stretching forces due to deformation energy absorption by fastening resilient elements.
