转盘轴承（回转支承）——三排圆柱滚子组合轴承（13系列） 三排滚柱式回转支承具有三个座圈上下及径向滚道各自分开，使得每一排滚柱的负载都能确切地加以确定，能够同时承受各种载荷，是四种产品中承载能力最大的一种，轴、径向尺寸都较大，结构牢固，特别适用于要求较大直径的重型机械，如斗轮式挖掘机、轮式起重机、船用起重机、钢水运转台及大吨位汽车起重机等机械上。 Three – row roller slewing bearing has three seat – rings, which separate the upper, lower and radial races, via which the load of simultaneously and its load capacity is the largest one among the four models. Thanks to the large size of its axle and radius, it is sturdy and especially suitable for heavy – duty machines which require large working radius, such as. Bucker – wheel excavators, wheeled cranes, ship cranes, steel transporters, heavy duty mobile cranes etc. 转盘轴承（回转支承）型号的表示方法： 序 号 ?轴承型号 Designations ?外型尺寸 Boundary ?安装孔尺寸 Bolt hole diameter 结构尺寸 Structure dimensions 齿宽 Gear face 模数mod ulus 外齿External gear 内齿Internal gear 最大圆周力 Max. circumferential force 额定负荷Basic .load ratings Coa 质量 Mass 无齿式non-gear type 外齿式external gear type 内齿式internal gear type D d H D1 D2 Φ n n1 D3 d1 h1 h2 D’3 d’1 T b m De Z De Z 正火norma lization 调质temper mm mm mm mm 104 N ≈(kg) 1 130.25.500 131.25.500 133.25.500 634 366 148 598 402 18 24 4 537 526 32 10 474 463 32 80 5 664 130 337 68 5.0 6.7 275 35.2 224 132.25.500 134.25.500 6 664.8 108 338.4 57 6.0 8.0 2 130.25.560 131.25.560 133.25.560 694 426 658 462 597 586 534 523 5 724 142 397 80 5.0 6.7 308 39.9 240 132.25.560 134.25.560 6 724.8 118 398.4 67 6.0 8.0 3 130.25.630 131.25.630 133.25.630 764 496 728 532 28 667 656 604 593 6 808.8 132 458.4 77 6.0 8.0 345 45.1 270 132.25.630 134.25.630 8 806.4 98 459.2 58 8.0 11.0 4 130.25.710 131.25.710 133.25.710 844 576 808 612 747 736 684 673 6 886.8 145 536.4 90 6.0 8.0 388 51.7 300 132.25.710 134.25.710 8 886.4 108 539.2 68 8.0 11.0 5 130.32.800 131.32.800 133.32.800 964 636 182 920 680 22 36 741 830 40 770 759 40 120 8 1006.4 123 595.2 75 12.1 16.7 549 71.2 500 132.
