20150086140 | LINEAR MOTION GUIDE UNIT WITH LUBRICATING MEMBER - A linear motion guide unit makes application of lubricant around rolling elements at the turnaround passage to accomplish securely the maintenance-free lubrication over a prolonged period of time. | 03-26-2015 |
20150093053 | LINEAR GUIDEWAY AND END CAP MODULE THEREOF - An end cap module of a linear guideway for being installed on a sliding block, comprises: a cap having an oil-input hole and a resilient dustproof member installed on the cap. The dustproof member has an oil-guiding passage concavely formed on a surface thereof and communicated with the oil-input hole. When the end cap module is installed on the sliding block, the dustproof member is clipped between the cap and the sliding block. Thus, the instant disclosure provides the end cap module for reducing the design difficulty and producing difficulty of the cap. Moreover, the instant disclosure also provides a linear guideway. | 04-02-2015 |
20150110425 | LINEAR MOTION GUIDE APPARATUS HAVING LUBRICATING OIL WIPING MECHANISM - A linear motion guide device includes a slider slidably attached onto a guide rail, two dust caps oppositely attached to end portions of the slider respectively and each having a channel formed between two legs for slidably engaging with the guide rail, and each having a lip portion directed toward the guide rail for wiping the engaging surface of the guide rail, and the lip portions of the legs of the dust caps each include an inner flange directed toward the slider and each include a number of notches and a number of projections formed in the inner flange of each of the legs and offset from each other for wiping the lubricating fluid into the notches of the legs respectively. | 04-23-2015 |
20150125100 | LUBRICATING STRUCTURE FOR LINEAR MOTION GUIDE APPARATUS - A linear motion guide device includes a slider slidably attached onto a guide rail, an end cap having an inner side attached to the slider, the end cap includes an inlet for receiving a lubricating fluid, two chambers formed in two legs, a passage communicating with the chambers, a guiding pathway communicating with the inlet and the passage for separating the passage into two passageways which are communicating with the chambers of the end cap respectively, and a follower is slidably engaged in the guiding pathway and movable toward either the passageways of the end cap for partially blocking and for limiting the flowing of the lubricating fluid to the passageways of the end cap. | 05-07-2015 |
20150308505 | VACUUM PROCESSING SYSTEM, VACUUM PROCESSING DEVICE, LUBRICATING AGENT SUPPLY DEVICE, AND LUBRICATING AGENT SUPPLYING METHOD - A transport system is a vacuum processing system that includes a transport device that is provided in a vacuum, and a lubricating agent supply device that supplies lubricating agent to the transport device and provided in the ambient atmosphere. The transport device has a lubricating agent flow channel that is a channel for grease injected to a site subject to lubrication. The lubricating agent supply device has a grease server that stores a lubricating agent in the ambient atmosphere, a lubricating agent supply pipe which is a channel that guides the grease stored in the grease server to the lubricating agent flow channel and that connects the grease server and the lubricating agent flow channel, and an exhaust pump that exhausts the inside of the lubricating agent supply pipe. | 10-29-2015 |
20150337898 | LINEAR GUIDEWAY - A linear guideway includes an end cap and a resilient sheet. The end cap includes a main plate, a surrounding plate, and two side positioning pillars. The surrounding plate and the side positioning pillars are perpendicularly extended from the main plate. The inner edge of the main plate has two protruding segments facing with each other. The side positioning pillars are respectively arranged adjacent to the first protruding segments. The resilient sheet has two first side positioning holes respectively sleeving the two first side positioning pillars, and the resilient sheet is disposed on the main plate. Thus, by the cooperation of the first side positioning pillar and the first side positioning hole, the resilient sheet is firmly received in the end cap and the first side positioning pillars support the inner edge of the resilient sheet. | 11-26-2015 |
20150345554 | LINEAR MOTION GUIDE UNIT - A porous compact impregnated with lubricant fits into a lengthwise hole in the carriage to apply the lubricant around balls rolling through a return passage to realize maintenance-free for lubrication. The carriage has a flat upper portion which has threaded holes lying midway between the widthwise opposed bulges to fasten counterparts to the carriage. The carriage has widthwise opposed corners where the flat upper portion merges the respective bulges. The corners each have therein a lengthwise hole in which the cylindrical porous compact impregnated with lubricant is inserted to extend across the overall length of corners. | 12-03-2015 |
20150345560 | Guide Carriage with Fastening Bore which is a Component of a Lubricant Flow Path - A guide carriage for an elongated guide rail includes a main body, an end cap, and at least one row of rolling bodies accommodated in a continuous bypass channel. The end cap bears indirectly against a longitudinal end face of the main body and has a fastening bore through which a fastening screw passes. The fastening screw is screwed into the main body. The continuous bypass channel has a supporting portion and a return channel that are connected via a curved bypass channel that is arranged in the end cap. A lubricant flow path is arranged in the end cap and extends from a lubrication port to the row of rolling bodies. A first cavity is arranged between the fastening bore and the fastening screw. The first cavity forms a component of the lubricant flow path. | 12-03-2015 |
