Abstract: A DEVICE FOR CONVERTING ROTARY MOTION TO LINEAR MOTION IN WHICH A SHAFT MEMBER AND A TUBULAR MEMBER ARE MOUNTED IN CONCENTRIC TELESCOPING RELATION, AND A BEARING UNIT IN THE FORM OF A PLURALITY OF BEARING BALLS ROLLING ON THE TUBULAR MEMBER AND MOUNTED IN A SPECIAL CAGE OR RETAINER IS INTERPOSED BETWEEN THE SHAFT MEMBER AND THE TUBULAR MEMBER, AND A WEDGE LOCK IS ESTABLISHED BETWEEN THE SHAFT MEMBER AND THE BEARING BALLS THAT WEDGE LOCKS THE BALLS BETWEEN THE TWO MEMBERS. THE BEARING UNIT IS MOUNTED IN A FIXED PLANE DISPOSED TRANSVERSELY OF THE DEVICE SHAFT AND TUBULAR MEMBER, AND THE BALLS ARE SPACED EQUIDISTANTLY ABOUT THE AXES OF SAID MEMBERS AND ROTATE ABOUT INDIVIDUAL AXES THAT ARE CANTED AT AN ACUTE ANGLE ON THE ORDER OF TWO DEGREES OUT OF PARALLELISM WITH THE LONGITUDINAL AXES OF SAID MEMBERS.

Abstract: The disclosure pertains to a device for converting rotary motion to linear motion that enables the provision of high force over long distance at low speeds providing a force conversion ratio on the order of 200 to 1 or better operating at 80 to 95 percent efficiency, and that is self-compensating to overcome inertia, in which a shaft member and a tubular member are mounted in concentric telescoping relation, and a bearing unit in the form of inner and outer races and rolling bearings interposed therebetween is wedged between the two in eccentric relation thereto with one of the races serving as a rolling element and being formed with a spherically contoured surface that establishes an elongate rolling contact area with the member to be moved linearly, and a ball wedge lock is established between the member that is rotated and the race that serves as the rotating element of the bearing. The bearing unit is mounted in a fixed plane at an acute angle transversely of the device members and has the axis of rotation of its rotating race lying in the plane that includes the axis of rotation of the rotating member. The position of the area of rolling contact between the rolling race and the linearly movable member relative to said plane of said axes establishes the pitch of the device, and the bearing unit is spring-biased to maximum pitch position, it being selfcompensating to decrease pitch and increase the force conversion factor in overcoming inertia and moving heavy loads. Either the inner or the outer member may be rotated to provide linear movement of the other member, and in practice the bearing unit is employed as a set of three such units forming a bearing assembly arranged to balance the forces acting through the device. Several different specific embodiments are disclosed.
