20090016653Guiding Device for a Synchronous Connector - A guiding device for a synchronous connector comprises a strip-like synchronous connector and at least one connecting member. Both ends of the synchronous connector are formed with two opposite fixing seats. The connecting member with elastic deformation characteristic is serially connected and fixed in the fixing seats at both ends of the synchronous connector, slide correspondingly to the clearance change during the operation of the two ends of the synchronous connector, and bend correspondingly to the turning action of the synchronous connector. By such arrangements, the elastic deformation characteristic of the connecting member can be utilized to avoid the collision interference with the rail wall surface, and the linear guiding device will be circulated smoothly and stably. In addition, the guiding device has the effect of absorbing the radial deformation of the synchronous connector and producing sufficient degree of freedom.01-15-2009
20090290818Cover Strip for a Linear Guide Rail - A cover strip for a linear guide rail, wherein a slide block is slidably disposed on the guide rail, a cover strip covers an upper surface of the guide rail, each of two sides of the guide rail extend outwards to form an extending surface with large slope, and each extending surface extends downward to form a flange, two sides of the central portion of the cover strip are provided with extending portions, and each extending portion extends downwards to form an engaging portion, the structures extending from two sides of the cover strip are configured in the shape of the corresponding structures of the guide rail, and a free end of each engaging portion extends downward to cover the ridge of each flange in such a manner that the cover strip can be positioned on the guide rail assuredly and stably.11-26-2009
20100046864Circulating Structure for a Linear Guideway - A circulating structure for a linear guideway is arranged in a circulating assembly the linear guideway. The linear guideway includes two circulating assemblies, and each circulating assembly is provided with a circulating channel. Each circulating channel is provided with a third guiding groove. A rolling element system is arranged in the circulating channel and consists of plural rolling elements and a rolling element chain. The rolling element chain includes plural spacers and a linking portion located at both sides of the plural spacers to link them with one another. The linking portion circulates along the center line of the third guiding groove, and the third guiding grooves have a constant width.02-25-2010

20110170809AUTOMATIC LUBRICATION STRUCTURE OF SLIDE MECHANISM - An automatic lubrication structure of slide mechanism. The automatic lubrication structure includes a guide section, a slide section slidably disposed on the guide section, and a lubricating section fixedly disposed on the guide section. The lubricating section has an oil reservoir with an internal cavity for containing therein a lubricant or the like. The lubricating section further has a communication passage and multiple oil-filling holes formed on lateral sides of the guide section in contact with the slide section. The cavity communicates with the oil-filling holes via the communication passage. The slide section is movable to push a push member for making the lubricant or the like contained in the cavity spill out of the oil-filling holes so as to provide lubrication effect for contact faces between the guide section and the slide section.07-14-2011
