Design on 36×14-2011.00 Skid Steer ND HPS Solid Tire of High Load Trackless Construction Machinery Vehicle for Coal Mine

介绍36×14-2011.00 Skid Steer ND HPS高载荷煤矿用无轨工程机械车辆实心轮胎的设计。结构设计:外直径908 mm,断面宽352 mm,行驶面宽度326 mm,行驶面弧度高6.8 mm,胎圈着合直径518.5 mm,胎圈着合宽度286 mm,断面水平轴位置(H_(1)/H_(2))0.873,采用无方向横向大花纹块类型花纹,花纹深度15.5 mm,花纹饱和度74.6%,花纹周节数24,在断面水平轴位置上设计椭圆锥形胎侧减震和散热孔,长度超过胎冠宽度的1/2。施工设计:胎面采用3层胶料结构,钢丝圈结构为10根×7层,钢丝圈直径为530 mm,钢丝圈数量为6个。采用机头直径为470~530 mm、机头宽度为500 mm的成型机成型、平板硫化机硫化轮胎。成品轮胎试验结果表明,轮胎充气外缘尺寸、物理性能、耐久性能、静负荷性能和防静电性能达到设计和特种车辆的要求。

The design on 36×14-2011.00 Skid Steer ND HPS solid tire of high load trackless construction machinery vehicle for coal mine was introduced.In the structure design,the following parameters were taken:overall diameter 908 mm,cross-section width 352 mm,width of running surface 326 mm,arc height of running surface 6.8 mm,bead diameter at rim seat 518.5 mm,bead width at rim seat 256 mm,maximum width position of cross-section(H_(1)/H_(2))0.873,using non directional lateral large block pattern,pattern depth 15.5 mm,block/total ratio 74.6%,and number of pattern pitches 24,elliptical tapered sidewall damping and heat dissipation holes were designed on the horizontal axis of the section,with the length exceeding 1/2 of the crown width.In the construction design,the following processes were taken:3-layer compound structure for tread,7 layers of 10 steel wires for the steel ring construction,diameter of the steel ring was 530 mm,number of the steel ring was 6,and using a building machine with head diameter of 470~530 mm and head width of 500 mm to build tires and using a hot plate press to cure tires.The test results of the finished tire showed that the inflated peripheral dimension,physical property,endurance performance,static load performance and antistatic performance met the requirements of the design and special vehicles.
