20080253702 | Linear Guideway with a Synchronous Connector - A connector for a linear guideway is integrally formed by injection molding. The mold assembly of making the connector includes an upper mold, a lower mold and a pin. The variable cross section design of the pin enables the connector to have a plurality of ring-shaped portions with more than two different axial thicknesses, so that the distances between the respective rolling elements are different, and the frequencies of the respective rolling elements are also different, and as a result, the resonance sound pressure caused by the linear guideway and the machine are reduced. In addition, the variable cross section design of the pin reduces the manufacturing difficulty of making a relatively long connector. | 10-16-2008 |
20080292226 | Linear motion guide apparatus - A linear motion guide device includes a slider and two end caps attached to side portions of the slider, and two holding assemblies attached to two side legs of the slider and the end caps for forming four endless ball guiding channels and for smoothly receiving four chains of rolling members, the holding assemblies each include two L-shaped holding devices and a retaining device attached to the leg of the slider and the end caps, and the holding devices each include two detachable halves for allowing the holding devices to be easily and quickly molded and for allowing the holding devices to be easily disengaged from the mold devices. | 11-27-2008 |
20080304773 | Linear motion guide apparatus - A linear motion guide device includes a slider slidably attached onto a guide rail, an end cap attached to each side of the slider, a cover band engaged onto the upper portion of the guide rail and having an end portion extended out of the end portion of the guide rail, and a block attached to the end portion of the guide rail and having an opening for receiving the end portion of the cover band, a wedge member is slidably engaged into the opening of the block and includes an inclined surface for slidably engaging with the inclined surface of the block and for securing the end portion of the cover band to the block when the wedge member is engaged into the opening of the block, a fastener may force the wedge member to secure the end portion of the cover band to the block. | 12-11-2008 |
20080317391 | Parallel Spacer for a Linear Guideway - A parallel spacer for a linear guideway comprises a plurality of parting portions, connecting portions and a retaining portion. Each of the parting portions is a thin member disposed between each pair of neighboring rollers. The connecting portions are employed to connect the parting portions and the retaining portion, and the retaining portion is arranged at a side of the respective rollers and located in an axial direction thereof, the retaining portion is an integral structure for connection with the respective connecting portions. | 12-25-2008 |
20100215295 | Roller holder for motion guide device - A roller holder includes a number of couplers disposed between two longitudinal rods for coupling the rods together and for forming a number of compartments to receive rolling members, and two retaining devices disposed in each compartment of the roller holder and attached to the rods for retaining the rolling members in the compartments and between the rods and the couplers of the roller holder, and for preventing the retaining devices from being impacted by the rolling members, the retaining devices each include a projected portion located above the rods and a protruded portion located below the rods and the couplers for engaging with the rolling members. | 08-26-2010 |
20110033141 | Circulating System for a Linear Guideway - A circulating system for a linear guideway comprises a slide block, a slide rail, two cover plates, two end caps and plural rolling elements. The slide block is disposed on the slide rail. The two cover plates and the two end caps are disposed at two opposite ends of the slide block, respectively. Between the two cover plates and the two end caps are disposed inner return and outer return blocks, respectively, and the inner return and the outer return blocks each are defined with half rolling paths to form complete rolling paths. Both ends of a complete rolling path and both ends of a complete loaded path are connected to both ends of two complete return paths to complete circulation paths. The inner and outer return blocks are made by common plastic injection molding, and the formed rolling paths are made of plastic material. | 02-10-2011 |
20120006136 | LINEAR MOTION TRANSMISSION APPARATUS WITH A CHAIN - A linear motion transmission apparatus with a chain comprises at least one flexible link and a plurality of spacers, the spacers are equidistantly spaced apart and connected by the link, each two neighboring spacers define a holding space for holding rolling elements, each of the spacers has two separated arcuate retaining portions used to contact and hold the rolling elements.
