  • Cone roller lock device
    Patent number: 9151342
    Abstract: A roller lock device has a shaft and a housing configured over the shaft for selective relative movement thereto. A plurality of rollers is configured between the housing and the shaft, at least some of which are substantially conically shaped. A cage is configured between the housing and the shaft and adjacent the rollers such that the rollers are at least partially constrained from movement by the cage. A control is configured to move the rollers axially thereby engaging and disengaging the roller lock. The housing has ramps configured to receive the rollers, the ramps having a curved contour.
    Type: Grant
