[0029] Embodiment 1
[0030] This embodiment introduces the matching design of double-V-shaped rollers (22) and V-shaped slides (11) and its operation mode. The double-V-shaped rollers (22) are provided with a V-shaped angle range of 70°-110° to adapt to V-shaped slides (11) of different specifications. The double-V-shaped rollers (22) are installed on the roller support frame (3) through the roller shaft (21) and are supported by high-precision bearings (23), so that they can roll stably in the V-shaped slide (11). During operation, the double-V-shaped rollers (22) form linear contact with both sides of the V-shaped slide (11), ensuring that the rollers are evenly stressed when rolling, reducing sliding resistance, and avoiding tilting or jamming problems caused by excessive unilateral stress. Compared with the traditional single-V-shaped roller structure, the contact area of this structure is optimized, so that the roller will not be excessively off-loaded when operating under high load, and the sliding accuracy of the guide rail system is improved. The micro-texture coating (12) of the V-shaped slide (11) can reduce the friction between the roller and the slide, improve the service life of the roller assembly (2), and reduce the operating noise.

The roller assembly (2) adopts two symmetrically distributed double-V-shaped rollers (22), which are fixed on the roller support frame (3) through the roller shaft (21), so that the two rollers simultaneously contact the two sides of the V-shaped sliding groove (11), thereby balancing the stress and preventing the unilateral wear of the roller from being aggravated. In the sliding process, the double-roller structure can reduce the inclination or slipping phenomenon of the roller caused by unilateral excessive stress, and improve the running accuracy of the guide rail system. In addition, in order to further optimize the running stability of the roller assembly (2), the roller shaft (21) is supported by a high-precision bearing (23), and low-friction lubricating grease is used to reduce the resistance when the roller rotates, improve the smoothness of rolling, and reduce wear in the long-term operation process.
