074840000 | ROTARY DRIVEN DEVICE ADJUSTABLE DURING OPERATION RELATIVE TO ITS SUPPORTING STRUCTURE | 7 |
20090056498 | BALL SCREW RESETTABLE MECHANICAL DISCONNECT - A disengagement/disconnect assembly for disengaging a generator from a gear box includes an inner ball screw having an angled threading on an outer surface thereof and surrounding and operatively engaged to a rotating generator drive shaft to cause rotation of the inner ball screw, the inner ball screw having axial dog teeth engaged to corresponding teeth of the gear box drive shaft, an outer ball screw surrounding and normally rotating with the inner ball screw and having a spherical ball and an angled ball track between the inner and outer ball screws, a lock, and a brake for slowing or stopping rotation of the outer ball screw so that the inner ball screw rotates relative to the outer ball screw along the ball track and slides axially toward the lock thereby disengaging the generator from the gear box drive shaft. | 03-05-2009 |
20100024594 | CONCENTRIC JOINT MECHANISM CAPABLE OF ROTATING WITH MULTIPLE DEGREES OF FREEDOM - A concentric joint mechanism includes a frame, a flexible spherical body, a first friction wheel, a first power device, and a fixing device. The flexible spherical body is disposed inside the frame. The first friction wheel is disposed inside the frame and abuts against the flexible spherical body for driving the flexible spherical body to rotate in a first direction. The first power device is connected to the first friction wheel for providing power to the first friction wheel. The fixing device is connected to the frame and abuts against the flexible spherical body for fixing the flexible spherical body inside the frame together with the first friction wheel. | 02-04-2010 |
20100107814 | HOLLOW ACTUATOR - A hollow actuator includes a motor section, a reduction gear section, a brake section, a rotation position detecting section, and a shaft having a hollow shape and transmitting rotation, wherein the motor section and the brake section are disposed in a same chamber. | 05-06-2010 |

20090205465 | SLIDING DEVICE COMPOSED OF COMBINED STRUCTURE OF SCREW BOLT AND NUT - An object of the present invention is to provide a sliding device that can surely reduce damage caused by mutual sliding behavior. To achieve the object, a sliding device in which a screw bolt having a male thread and a nut having a female thread hole in which a female thread is formed on an inner circumference are screwed together in a state capable of screw rotation and applied with repeating screw rotation so that the male thread and the female thread are subjected to a sliding load, wherein when Vickers hardness of a first metal material constituting the male thread of the screw bolt is H | 08-20-2009 |
20100132506 | FEED DRIVE MECHANISM AND FLEXIBLE CONNECTION PLATE THEREOF - A flexible connection plate is used in a feed drive mechanism. The flexible connection plate has a first portion, a second portion joined to the first portion, and a plurality of elastic grooves between the first portion and the second portion. The first portion and the second portion are fixed to a nut seat and a lead screw nut of the feed drive mechanism respectively. The elastic grooves are axially penetrating the connection plate. Adjacent elastic grooves have an overlapping section respectively, such that the flexible connection plate has a characteristic of elastic deformation in a radial direction, so as to absorb errors resulted from assembly, and improve non-parallelism resulted from the assembly errors, thereby increasing the feed accuracy of the feed drive mechanism. Furthermore, the rigidity of the flexible connection plate in an axial direction is high enough to drive the feed drive mechanism to be positioned precisely. | 06-03-2010 |
