  • Automatic resetting torque limiter capable of high speed continuous operations in released mode
    Patent number: 8696473
    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.
    Type: Grant

  • Automatic Resetting Mechanical Torque Limiting Clutch
    Publication number: 20090305794
    Abstract: 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.
