| 摘要 |
A lubricated, abrasion-resistant filler for the bark-protective deformable pads of tree shaker clamping jaws comprises small, jagged-edged chips of a high impact strength, low heat-transfer polymer, such as nylon 66, impregnated with a dry, high-melting temperature lubricant, such as molybdenum disulfide. The chips provide increased wear resistance due to less heat buildup from friction. By interlocking, the chips maintain a direct transfer of pressure to the tree from the vibrating jaws without slippage.
