| 中文摘要: |
| 介绍8.25－16 16PR单侧加强型免橡胶环轮式挖掘机轮胎的设计。结构设计：外直径 830 mm，断面宽 195 mm，行驶面宽度 192 mm，行驶面弧度高 6 mm，胎圈着合直径 405 mm，胎圈着合宽度 165 mm，断面水平轴位置（ H1/ H2） 0.82，胎面采用有向花纹，花纹深度 20 mm 24，花纹饱和度 51%，花纹周节数 24，以胎侧集成加强台结构替代传统双胎并装用橡胶环。施工设计：胎面使用全丁苯橡胶胶料配方，胎体采用6层1870dtex/2锦纶6帘布，缓冲层采用2层930dtex/2V3锦纶6帘布，胎圈采用双钢丝圈结构，采用1B成型机成型、两半模硫化机硫化。成品轮胎的充气外缘尺寸和物理性能均符合设计和国家标准要求，同时市场反馈轮胎免维护性显著提升。 |

| The design of 8.25－16 16PR single-side reinforced wheel excavator tire without rubber ring was introduced.In the structure design，the following parameters were taken：overall diameter 830 mm，cross-sectional width 195 mm，width of running surface 192 mm，arc height of running surface 6 mm，bead diameter ar rim seat 405 mm，bead width at rim seat 165 mm，maximum width position of cross-section（ H1/ H2） 0.82，using directional patterns for tread，pattern depth 20 mm，block/total ratio 51%，number of pattern pitches 24，using integrated reinforcement platform structure on the sidewall to replace traditional rubber ring for twin tire installation.In the construction design，the following processes were taken：using styrene-butadiene rubber compound formula for tread，6 layers of 1870dtex/2 nylon 6 cord for carcass，2 layers of 930dtex nylon 6 cord for cushioning layer，double steel wire ring structure for bead，and 1B building machine to build tire and two-part mold curing press to cure tire.The inflated pepheral dimension and physical properties of the finished tire met the design and national standard requirements，and the market feedback showed a significant improvement in maintenance-free performance. |
