    摘要: To improve workability and sealing performance of a coolant when a plurality of nuts in a ball screw are brought into contact with one another, the plurality of nuts being coupled to one another, assembled to one threaded shaft and cooled by flowing the coolant through through-holes formed in the plurality of nuts in axial directions of the plurality of nuts. The ball screw (1) includes counterbores (4, 5) of the through-holes (3) formed on opposing end faces of both of adjoining nuts (21, 22), and a ring-shaped sealing member (6) inserted thereto. The counterbores (4, 5) are formed such that a depth (D2) of one counterbore is larger than a length of the sealing member (6) (D2 > L), and the a depth (D1) of the other counterbore is smaller than the length of the sealing member (6) (D1

    摘要: A control device is produced for enabling a locked-up state at a low speed range and preventing thereby-caused insufficiency in the lubricating oil supply amount to a transmission. The control device controls the lubricating oil supply amount to a transmission in a construction machine including a torque converter with a lock-up clutch. The control device includes a clutch state determining section, a lubricating oil amount detecting section and a lock-up clutch controlling section. The clutch state determining section determines whether or not the lock-up clutch (7) is being coupled. The lubricating oil amount detecting section detects whether or not the lubricating oil supply amount to the transmission (2) is short of a preliminarily set supply amount. The lock-up clutch controlling section decouples the lock-up clutch (7) when the lock-up clutch (7) is being coupled and the lubricating oil supply amount is short of the preliminarily set supply amount.
