Document Type and Number:
WIPO Patent Application WO/2019/208086
Kind Code:
A1
Abstract:
[Problem] To provide a belt type grinding tool configured so that an endless grinding belt can be more efficiently cooled. [Solution] This belt type grinding tool 10 is provided with a fan 36 disposed on the inside of the outer peripheral section 28 of a drive pulley 22. The belt type grinding tool 10 has formed therein an air flow path 68 which extends on the inside of the outer peripheral section 28 from an inner opening 62 in a cover 52, passes through a through-hole 46 in the drive pulley 22, bends around a side edge 28b of the outer peripheral section 28, extends on the outside of the outer peripheral section 28, and reaches an outer opening 64 in the cover 52. When the fan 36 is rotated together with the drive pulley 22, outside air is sucked into a containing space 58 from the inner opening 62, flows along the air flow path 68 and is discharged to the outside of the containing space 58 from the outer opening 64. The drive pulley 22 and the endless belt 24 are efficiently cooled by the air.
