DEVICE FOR CUTTING HARD MATERIALS AND ITS DURABLE WORKING ELEMENT Russian patent published in 2012 - IPC B28D1/08 

FIELD: mining.

SUBSTANCE: The device relates to mining and cutting treatment of various hard materials , such as stone mining and stone cutting. The device for cutting hard material consists of flexible durable working element and the frame fitted with the cutting feed and a drive mechanism . The cutting bushings and arbor sleeves are separated by elastic washers. The cutting feed consists of a roller couple fitted with peripheral circular grooves where sides of belt transmission are installed, and one of the rolls is fitted with a linear drill. The drive mechanism consists of a belt transmission and a roller couple fitted with peripheral circular grooves, one of the rollers is a guide roller and interlocked with the device drive. The sides of the durable working element belt transmission are flexibly mounted into the peripheral circular grooves of the cutting feed and and go around the cutting feed rollers, through the peripheral circular grooves of the drive mechanism so that they form an open lap which can move linearly when the cutting feed is moved. The sides of belt transmission of the cutting feed and the drive feed tightly hold the flexible durable working element together with the contact surfaces of the peripheral circular grooves in areas where they come into contact.

EFFECT: durability increase of the working element and in the reduction of cutting energy consumption.
