Title:
FRICTION METHOD FOR DRUM-TYPE TORQUE LIMITER
Document Type and Number:
WIPO Patent Application WO/2024/017417
Kind Code:
A1
Abstract:
A friction method for a drum-type torque limiter. A spiral groove-type structure is additionally arranged to a friction surface of a gear member (5) to discharge powder dropping from a friction member (4), thereby avoiding the phenomenon of powder accumulation between friction surfaces caused by friction for a long time, and reducing the influence of powder accumulation on friction performance. The friction method for a drum-type torque limiter effectively solves the problem of an unstable torque limit value and reduces maintenance work.
