Abstract: A ball screw assembly, wherein the circulate component is positioned in the nut by inserting a protrusion in a notch, so that the circulate component is positioned easily, and the problem of assembly difficulty is solved. The method of fixing the circulate components in the nut is that: the circulate component is formed with an axial hole and the radial hole that are connected to each other, the axial hole of the circulate component is aligned to the axial locking hole of the nut, and then liquid resin is injected into the axial hole of the circulate components, and the liquid resin will form a locking members after curing, thus fixing the circulate component in the nut. Due to the formation of the locking member is determined by the diameter of the hole to be machined, the configuration of locking member will be varied in response to the diameter of the hole to be machined. Whatever the diameter of the hole to be machined changes or not, it will not affect the interchangeability of the locking member. Therefore, the production cost is saved since it doesn't need to prepare different sized locking members.

Abstract: A fixed torque preload piece is positioned between two nuts of a ball screw, the preload piece is formed with through hole located in an axial direction of the two nuts for receiving at least two steel balls. Two terminal openings of each of the through holes are defined in the surfaces of the preload piece facing the two opposite nuts. Three radial threaded holes are formed in the outer periphery of the preload piece, and the threaded holes are vertical to and in communication with the through holes. An adjusting member, an elastic member and an adjusting screw are received sequentially in the respective threaded holes. The steel balls in the through holes are pushed against the two nuts by the arc-shaped abutting surface of the adjusting member, the pushing of the steel balls can produce an adjustable preload, and can absorb the sudden increase of the pressure effectively, thus obtaining the objective of the present invention of outputting torque stably.

Abstract: The rotating nut ball screw unit with lubricating arrangement has a lubricating device composed of a main body, a collar and a bearing. The main body is provided with several oil holes and is attached to the end surface of the nut. The main body is relatively rotatable with respect to the collar intercalating the bearing therebetween. An oil storage forces the lubricant into an oil reserving space surrounded by the main body, the collar and the bearing. The oil reserving space is in communication with the oil holes and allows the lubricant to be forced into the main body and then to reach the surface of the screw bolt via oil holes. The forced lubrication arrangement of the present invention ensures a better lubricating effect.
