| 摘要 |
<p>The present invention discloses a mechanical arm comprising an arm and a bearing bracket. The mechanical arm of the present invention is made of a ceramic material and has the characteristics of ceramic materials-high heat resistance, high abrasion resistance, high hardness, high strength, low friction coefficients and low thermal expansion coefficients. Thus, the mechanical arm of the present invention has less abrasion loss, less sway caused by over abrasion and less deformation caused by sway.</p> |
