Abstract: A ball screw includes a load path and a non-load path defined between the screw shaft and the screw nut with the two ends of the non-load path respectively connected to the load path and a reflow channel of the return tube. The ball screw defines an imaginary horizontal plane and an imaginary sloping surface that are intersected with each other at the center axis of the screw shaft. The imaginary horizontal plane passes through the non-load path. The imaginary sloping surface passes through the junction between the non-load path and the load path. The imaginary sloping surface defines a negative included angle within 1˜3 degrees with respect to the imaginary horizontal plane to reduce the impact force rendered by each rolling member to the return tube, enhancing operational smoothness and reducing operational noise.

Abstract: A linear guideway is characterized in that it is capable of determining whether there is abnormal displacement of the return member based on the open or close of the circuit, and can output the abnormal signal immediately when the circuit is open. Compared with the conventional structure, since the present invention can be disposed only at one end of the slide block, both the number of components and assembly time can be reduced, and the diagnosis with precision and immediacy can be performed without high-deep algorithm, which can play a role of instant reminding before the linear guideway completely loses function. Therefore, the service life of the linear guideway can be known early to avoid the loss caused by the shutdown.

Abstract: An adjustable lubrication module of a linear guideway includes an end lid disposed at a slider and an oil scraper disposed at the end lid. The end lid has therein two opposing backflow-chambers. A feed-hole disposed between the backflow-chambers and an oil-guiding conduit disposed below the feed-hole are disposed on the end lid. Communication between the feed-hole and the oil-guiding conduit is achieved by a primary oiling-channel. Communications between the oil-guiding conduit and the backflow-chambers are achieved by a secondary oiling-channel. Therefore, oiling-channel adjustment performed on the adjustable lubrication module operating in conjunction with the linear guideway does not entail demounting the end lid from the slider, thereby preventing ball missing. The feed-hole and the oil-guiding conduit are not disposed at the junction of the end lid and the slider; hence, lubrication oil is prevented from flowing over the gap between the end lid and the slider.
