发明名称 Cone roller lock device
摘要 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.

主权项 1. A roller lock device comprising: a shaft configured for moving axially along a shaft axis; a housing configured over the shaft for selective relative movement thereto, the shaft configured to move linearly through the housing; a plurality of rollers configured between the housing and the shaft and in contact with the shaft, at least some of which are substantially conically shaped and each of which are configured to rotate about a roller axis, which extends a length of each roller and general perpendicular to the shaft axis; a cage configured between the housing and the shaft and adjacent each of the plurality of rollers such that the rollers are at least partially constrained from movement by the cage; a control configured to move the cage such that the cage in turn moves each of the plurality of rollers in a direction parallel along each roller axis; and wherein the housing comprises ramps configured to receive the rollers, the ramps comprising a curved contour.
