Embodiment Construction

[0009] figure 1 and figure 2 is the slewing section of the slewing bearing; figure 1 and figure 2 As shown, the six-row tapered roller slewing ring includes outer ring 1, outer ring gear teeth, 2, bolts, 3, outer ring, 4, rolling cone, 5, bolts, 6, upper plate of the middle ring, 7, Rolling cone, 8, bolt, 9, inner ring gear teeth, 10, rolling cone, 11, roller, 12, lower piece of middle ring, 13, roller, 14, rolling cone, 15, inner ring. It is characterized in that there are three rows of tapered raceways between the upper middle ring 6, the lower middle ring 12 and the outer ring 3, and the three rows of raceways are respectively loaded with rollers 4, 10, and 11, and the upper middle ring 6. There are three rows of tapered raceways between the lower part 12 of the middle ring and the inner ring 15, and the rollers 7, 13 and 14 are respectively installed in the three rows of raceways; the upper part 6 of the middle ring and the lower part 12 of the middle ring Connected ...

Abstract

The invention discloses a rotary bearing with six rows of rolling cones. The rotary bearing is divided into an inner ring, an outer ring and a middle ring, and is characterized in that the middle ring is divided into an upper part and a lower part which are fixed with each other through a bolt, wherein three rows of rolling cone roller ways are formed between the inner ring and the middle ring as well as between the middle ring and the outer ring respectively; and rolling bodies are arranged in the roller ways. The rotary bearing has a reasonable structure and is cost-saving and easy to implement; the problem that an axial size of the conventional rotary bearing is required to be enlarged in order to meet the requirement for relatively high bearing capacity is solved; and the bearing capacity of the rotary bearing is improved by over 50% than the common rotary bearing with three rows of columns.

Description

technical field [0001] The invention belongs to a slewing bearing, in particular to a slewing bearing suitable for occasions with particularly large loads. Background technique [0002] The traditional single row ball type, cross roller type, double row ball type and three row column type slewing bearings will use larger rolling elements to meet the larger load, or add a row of rolling elements, so that the axial dimension is larger. As slewing bearings are used in more and more fields, the performance of the main engine used is getting higher and higher, and the loads in all aspects will become larger and larger. At present, various roller slewing bearings are flooding the market, and the rolling state of the rolling elements is poor, and the service life is relatively short. It is impossible to expand the size of the main engine without limit while the machine is enlarged. It is necessary to make reasonable structural improvements to the supporting various components to m...
