  • Ball nut and screw assembly with travel limit stop
    Patent number: 4295384
    Abstract: This ball nut and screw assembly has a ramplike stop secured to screw shaft. On predetermined linear movement of the ball nut relative to the screw shaft, the balls contained in the ball nut are forced to climb the ramp and are compressively loaded to force radial expansion of the nut and to positively limit ball nut travel. The wedging effect provided by the stop requires additional power to continue movement which cannot be fulfilled by the input.
