A track clamp for coupling linear motion guide tracks with standard linear motion support bases without the use of fasteners comprises a clamp body having a plug portion and an outwardly-opening guide track-receiving channel, the plug portion having outwardly-extending deformable protrusions on its outer surfaces that, upon insertion of the plug portion into a selected slot of a support base, deform upon engagement with the slot thereby securing the plug portion in the slot, the track-receiving channel holding a linear motion guide track. In one embodiment upwardly-extending clamp arms formed in the plug portion by the guide track receiving channel deflect inwardly upon insertion of the plug portion into the selected slot thereby clamping the guide track in the channel.

A roller bearing sub-assembly can include a first mounting portion, a second mounting portion spaced apart from the first mounting portion, a first roller disposed between the first and second mounting portions and straps wrapped partially around different portions of the first roller. The first mounting portion, second mounting portion, first roller and straps are configured such that the first and second mounting portions are moveable relative to each other along a selected direction for a distance that is approximately equal to a circumference of the first roller in opposite directions from a mid-stroke position. Linear roller bearing assemblies and methods of forming linear roller bearing assemblies are also disclosed, as are multi-cylinder Stirling engines and a thermal energy recovery system.

Linear roller bearing assemblies can include a hub, a collar around the hub and roller bearing sub-assemblies disposed in a radial pattern around the hub. The roller bearing sub-assemblies can guide linear movement of the hub relative to the collar along a selected direction. Each roller bearing sub-assembly can include a roller and straps wrapped partially around the roller. Each strap is connected to at least one of the hub and the collar. And at least one of the straps can be connected to the roller while at least one of the straps can be circumferentially free of the roller. The hub and collar are moveable relative to each other along the selected direction for a distance that is approximately half of a circumference of the roller. Methods of forming linear roller bearing assemblies are also disclosed, as are multi-cylinder Stirling engines and a thermal energy recovery system.
摘要:
A method of making a bearing assembly and a bearing assembly is provided. The method includes the steps of extruding a support rail, providing a mounting surface on the support rail, mounting a bearing rail on the mounting surface and machining a bearing surface on the bearing rail. The bearing assembly includes an extruded support rail and a bearing rail. The bearing rail is of a harder material than the material of the support rail to which the bearing rail is mounted. The bearing rail further provides a machine polished linear contact.

Provided is a motion guide device achieving both of high strength and weight reduction and yet having excellent mass-productivity.The motion guide device has a raceway rail 1 having a rolling-element rolling part 1a; a moving block 2 having a loaded rolling-element rolling part 8c facing the rolling-element rolling part 1a and a rolling-element circulation passage including a rolling-element return passage 10a extending approximately in parallel with the loaded rolling-element rolling part 8c; and a plurality of rolling elements 3 arranged in the rolling-element circulation passage. The moving block 2 has a rolling part 8 made of steel and having the loaded rolling-element rolling part 8c, a mounting part 9 connected to the rolling part 8, having a mounting surface 9a for mounting the moving block 2 onto a counterpart device and having a specific gravity lower than that of the rolling part 8, and a return part 10 made of resin and having the rolling-element return passage 10a. As three materials different in strength and specific gravity are arranged in respective appropriate parts of the moving block, the moving block 2 can combine the strength with weight reduction.
