GRINDING ROLL Russian patent published in 1997 - IPC

FIELD: milling and crushing equipment. SUBSTANCE: grooves made in the body of the shaft and namely in the sections, which come in contact with bearings, accommodate heat conducting elements. Each of the elements contacts the inner race of the bearing and has a blind hole, which is coaxial with the hole available in the shaft, to form a channel connecting the air lock with the heat conducting element. Placed into this channel from the lock side is a temperature-sensitive element provided with a thermocouple, which comes in contact with heat conducting element forming a hot channel: bearing, heat conducting element, thermocouple of the temperature-sensitive element. The heat conducting elements are made of material possessing high heat-conductivity coefficient, for example, copper. EFFECT: improved accuracy in checking temperature of bearings, enhanced reliability and longer service life of grinding rolls. 2 cl, 2 dwg
