Embodiment Construction

[0014] like Figure 1-6 As shown, the tapered roller bearing of the present invention includes outer rings 1 and 2, inner rings 3 and 4, and tapered rollers 5 and 6, and an inner spacer ring 9 is arranged between two rows of inner rings 3 and 4. Tapered rollers 5 and 6 are defined on cages 7 and 8, respectively. in, figure 1 The cone angle of the left outer ring 1 is greater than the cone angle of the right outer ring 2; the width of the outer ring 1 is greater than the width of the outer ring 2; the inner diameter of the left inner ring 3 is larger than the inner diameter of the right inner ring 4, and the inner ring 3 The width is greater than the width of the inner ring 4.

[0015] In the figure, the inner diameters and widths of the two rows of inner rings are different. The row with the larger inner diameter is used to bear the main load, and the row with the smaller inner diameter bears the secondary load and plays a role in slightly aligning the whole set of bearings....

Abstract

The invention discloses a reducing tapered roller bearing for single-row matching, which comprises two rows of outer rings (1, 2) arranged oppositely, inner rings (3, 4) and tapered rollers (5, 6) between the inner and outer rings. An inner separation ring (9) is arranged between two rows of the inner rings. The tapered rollers (5, 6) are limited on a retainer between the inner and outer rings respectively, wherein a taper angle of the outer ring (1) on one side is larger than that of the outer ring (2) on the other side, the width of the outer ring (1) is larger than that of the outer ring (2), an inside diameter of the inner ring (3) on one side is longer than that of the inner ring (4) on the other side, and the width of the inner ring (3) is greater than the width of the inner ring (4). The double-row reducing tapered roller bearing of the invention has the advantages of reasonable design, simple structure, reliable property, high rotary speed, high bearing load and long service life.

Description

technical field [0001] The present invention relates to a bearing, and more particularly, to a tapered roller bearing. Background technique [0002] my country's oil drilling and production equipment, especially land oil drilling and production machinery, has reached a certain level after years of development. Products such as electric drive drilling rigs, cluster well drilling rigs, desert drilling rigs, inclined well drilling rigs, horizontal well drilling rigs and top drive drilling rigs have been developed. It meets the technical needs of various drilling rigs such as high-pressure jet drilling rigs. The manufacturing quality of drilling rigs has also reached the international level in the early 1990s, and the oil drill bit has reached the international level. This requires the matching bearing design and manufacturing level to be compatible with the international level. Due to the harsh working conditions of bearings used in oil drilling rig platforms, drilling rig bear...
