摘要： A motion guide device includes a ball nut attached onto a shaft and having helical grooves for receiving ball bearing elements, a tubular member is engaged with the ball nut and includes a ball circulating pathway communicative with the helical groove of the ball nut, and includes an intermediate segment, two curved segments, and two end coupling segments each having a ball guiding channel which includes a wider inner section for guiding and circulating the flexible coupling member of a ball coupler to smoothly move through the ball guiding channel of each end coupling segment and for preventing the flexible coupling member from being twisted. The tubular member is preferably formed by two half members.

摘要： A lubrication apparatus for the ball screw unit in which the grease state lubricant is used. There is formed a helical guide track in the lubrication apparatus. When the ball screw unit operates, a guide member rotates with the bolt, the grease stored in the guide track will flow ahead to the front terminal of the guide track and ooze out of the grease outlet to lubricate the bolt with the aid of a pressure produced due to the inertia of the flowing fluid, and the quantity of the oozed grease is determined by the size of the grease outlet. The lubrication of the ball screw unit can be performed automatically without relying on the external force.
