新型圆锥滚子轴承以及应用该轴承的新型轴系统
摘要：
本发明提供一种新型圆锥滚子轴承，包含面对面对称设置的双列内圈滚道(1w，1w’)、双列外圈滚道(2w，2'w’)以及设置在双列内圈滚道(1w，1w’)和双列外圈滚道(2w，2’w’)之间的双列圆锥滚子(3，3’)。所述双列圆锥滚子(3，3’)各自具有用于约束本列圆锥滚子并且防止滚子之间相互触碰的保持架(4，4’)。所述新型圆锥滚子轴承在双列圆锥滚子(3，3’)之间设置有可浮动的引导环构件(5)，用于为双列圆锥滚子(3，3’)提供轴向的抵靠和支撑，允许双列圆锥滚子(3，3’)随轴承的不对中运行而在滚道宽度方向上进行移位调整。新型圆锥滚子轴承在预紧的条件下具有不对中运行的能力，可取代传统轴系统中作为非定位端配置轴承使用的圆柱滚子轴承，消除后者在缺乏预紧的条件下所固有的刚度缺陷。
摘要（英）：

The invention provides a novel tapered roller bearing comprising double rows of inner raceways (1w, 1w') with face-to-face symmetrical arrangement, double rows of outer raceways (2w, 2'w') and double rows of tapered roller elements (3, 3') arranged between the double rows of inner raceways (1w, 1w') and the double rows of outer raceways (2w, 2'w'). The double rows of tapered roller elements (3, 3') both have cages (4, 4') for constraining corresponding rows of tapered roller elements and preventing mutual touching between the roller elements. According to the novel tapered roller bearing, a floatable guiding ring component (5) is arranged between the double rows of tapered roller elements (3, 3') and is used for providing axial relying and supporting for the double rows of tapered roller elements (3, 3'), the double rows of tapered roller elements (3, 3') are allowed to perform displacement adjustment in the raceway width direction along with misalignment running of the bearing. The novel tapered roller bearing has a misalignment running ability under a pre-tightening condition, can replace a cylindrical roller bearing used as a non-positioning end configuration bearing in a traditional shaft system, and eliminates inherent rigidity defects of the cylindrical roller bearing under a condition of lack of pre-tightening.
