Abstract
A resettable torque limiter for installation between two rotary members, which can smoothly disengage upon application of predetermined torque acting between the members and smoothly reset upon decline of applied torque below the predetermined level. An undulating engagement surface formed on one member according to a function preferably an eighth power polynomial is engaged by a plurality of engagement elements on the other member which smoothly ride over lobes formed on the engagement surface when the torque limit is exceeded without causing any discontinuities in acceleration or jerk when the driving connection between the rotary members is interrupted until the applied torque declines below the preset limit.
