A friction-coupled core ring assembly stabilizes governor rope tension across elevator heights while limiting harmful force to the safety module.
A coil spring and undulating shank interfaces keep disposable surgical torque drives within preset limits at 50-1300 RPM over repeated actuations.
A combined belt clutch and overload clutch cuts drivetrain parts and space while keeping belt tension and adjustable hydraulic torque protection.
Recessed protuberances let lubricant flush wear debris from a tolerance ring, reducing wear and helping torque limiters maintain torque capacity.
A rubbery bushing compresses undulating torque interfaces to keep disposable medical tool drives within torque limits from 50 to 1300 RPM.
Segmented guide zones and a recessed bore help clutch sleeves maintain bore tolerance while improving molding, lubrication, and contamination passage.
A silicone grease with zinc extreme-pressure additives raises clutch friction while protecting metal surfaces from wear in frequent starter use.
A multispeed gear train keeps a low-pressure spool generator within a usable output speed range, avoiding stall at low RPM.
An electric ball screw actuator replaces hydraulic gate drives to avoid fluid leaks, reduce maintenance, and keep bollard operation stable in all seasons.
A dual-joint torque transfer attachment locks under load to absorb reaction torque, then unlocks for fast reorientation across fastener angles.
A retractable cord and planetary gear transmission switch shades between extend, retract, and open-close modes with precise control.
A friction-coupled core ring assembly limits rope tension and filters braking force to protect the elevator safety activating module.
