Automatic Resetting Mechanical Torque Limiting Clutch

摘要

A resettable torque limiter for installation between two rotary members, which can smoothly disengage upon application of a predetermined torque acting between the members and smoothly reset upon decline of applied torque below the predetermined level. An undulating cam surface formed on one member is engaged by one or more cam followers on the other member which smoothly ride over undulation peaks comprising cam lobes when the torque limit is exceeded and the driving connection between the rotary members is interrupted until the applied torque declines below the preset limit.
