Patent JP-S63172056-A (JP)
Title: Screw device with recirculating adjoint roller
Inventor: BERUNAARU DEYURUSO
IPC: F16H25/22
Filed: 1987-12-22
Abstract: Rollers situated on the circumference of a threaded screw inside a nut have a cavity at each end containing a spring and a pin. When a roller enters the recirculation groove, the spring/pin assembly bearing against the cap recirculates the roller towards the interior of the nut. By enabling the roller to be repositioned at the time of its reinsertion between the threads of the screw and of the nut, this arrangement provides for flexible operation of the screw.
