摘要： A ball screw device comprises a screw shaft, a nut mounted on the screw shaft, and a number of balls interposed between the screw groove of the screw shaft and the screw groove of the nut. The screw shaft has a ball circulation groove communication-connecting the downstream and upstream sides of the screw groove to return the balls from the downstream to the upstream side for circulation in the screw groove of the screw shaft. The ball circulation groove is formed in a curved shape sinking radially inward in the intermediate region as seen in the ball rolling direction, and in a shape curving radially outward in the regions at the opposite ends. It is arranged that the locus of the center of the ball rolling in the regions at the opposite ends and the locus of the center of the ball rolling in the screw groove of the screw shaft satisfy predetermined conditions concerning the circulation of the ball.

摘要： Provided is a screw device manufacturing method which ensures high productivity and adequate nut strength.
The screw shaft manufacturing method of the present invention includes: a groove forming step of forming a loaded ball rolling groove in a flat plate; and a nut forming step of bending the flat plate into a ring to form a nut. As the groove forming step of forming of the loaded ball rolling in the flat plate is followed by the nut forming step of bending the flat plate into a ring, sufficient strength of the nut can be easily achieved. Besides, a high compression stress is left in the loaded ball rolling groove in the inner surface of the nut.

摘要： The invention relates to a ball screw, comprising a spindle (1), a nut (3) surrounding the same and balls (4) which are located between them, said balls being arranged in such a way that they can roll in the screw race (2) configured on the spindle (1) and in corresponding screw races (7, 12) configured on rings inside the nut (3). The screw race (7, 12) of one of the rings situated in the nut (3) respectively, has a deviating area for guiding the balls (4) back from a run-out end of a common turn in the screw races (2, 7, 12) to a run-in end of this turn. According to the invention, a screw race (7, 12) is configured on a front face on each of the rings located in the nut (3, 15). The screw races (7, 12) of two adjacent rings, together with the screw race (2) of the spindle (1, 18), delimit a continuous circular channel for the balls (4).

摘要： An actuator (10) is disclosed for movement between a retracted position and an extended position. The actuator (10) can be used to pivot a pylon (14) in a tilt rotor aircraft relative to the aircraft wing (12) between a helicopter mode and an aircraft mode. The actuator (10) is provided with an inner ball screw drive unit (20) and an outer ball screw drive unit (22) which provides for limited motion should one of the drive units jam. Further, the actuator (10) can be operated from either end of the actuator. Each ball screw (28, 52) in the actuator is associated with a tube (30, 54), preferably of carbon fiber composite, which forms a secondary load path if the screw fails.
