Abstract
The utility model discloses a six-row rolling-cone type slewing bearing which comprises an inner ring, an outer ring and a middle ring. The six-row rolling-cone type slewing bearing is characterized in that the middle ring is divided into an upper portion and a lower portion. An upper portion and a lower portion of the middle ring are fixed together through bolts. Three rows of rolling cone raceways are arranged between the inner ring and the middle ring, and three rows of rolling cone raceways are arranged between the middle ring and the outer ring. Rolling bodies are arranged in the raceways. The six-row rolling-cone type slewing bearing is reasonable in structure and easy to achieve, saves cost, and can effectively solve the problem that the axial dimensions of a traditional slewing bearing need enlarging in order to satisfy larger bearing capacity. Compared with a common three-row column type slewing bearing, the bearing capacity of the six-row rolling-cone type slewing bearing is increased by more than 50%.
Description
Technical field
The utility model belongs to a kind of pivoting support, specifically belongs to a kind of pivoting support that is applicable to the large especially occasion of load.
Background technique
The tradition single-row ball type, crossed pin roller type, the double-row-ball formula, three organ timbering formula pivoting supports can be selected larger rolling element for satisfying larger load, perhaps increase by a row rolling element, thereby so that axial dimension are larger.Along with the field that pivoting support uses is more and more wider, applied host performance is more and more higher, and each side load is with increasing.At present, various roller type pivoting supports are flooded with market, and the rolling situation of its rolling element is poor, and the life-span is relatively short.Unrestrictedly simple size amplification of main frame must be carried out rational architecture advances to supporting various parts, to satisfy the demand of growing high-performance mechanical when machinery maximizes.
Summary of the invention
The purpose of this utility model provides a kind of pivoting support that is applicable to the large occasion of load.
For achieving the above object, the utility model adopts following technological scheme: pivoting support is divided into inner ring, the outer ring, and centre circle, wherein centre circle is divided into the upper and lower part, and part and bottom are bolted between dividing on the centre circle; Between inner ring and the centre circle, centre circle and outer ring among have three row's tapper raceways, all puts into rolling element in the raceway.
Six row's tapper formula pivoting supports are on the basis of three row's roller type pivoting supports, have added the with it rolling element (tapper) of symmetry of three rows in its plane of rotation, and this kind structural type has the following advantages: 1, this kind structural type can increase contact line length; 2, reduce the slip of rolling element, increased the pure rolling of rolling element, and then improved the rolling condition of rolling element, improved its working life; 3, can provide internal gear to drive, external gear drives two kinds of drive forms; 4, increase the bolt row, improved rigidity, improved bolt group bearing capacity; 5, improved axial carrying capacity; 5, improved resistance to capsizing.This structure is strengthened bearing to have had again aspect thrust load and the tilting moment very significantly, and can realize the function of bi-directional rotary.Thereby reach in the situation of relatively-stationary axial dimension, can bear the purpose of larger load.This is confirmed in the computer finite element analysis.

Embodiment
Fig. 1 and Fig. 2 are the revolution section of pivoting support; By Figure 1 and Figure 2, six row's tapper roller pivoting supports comprise outer ring 1, the outer ring gear teeth, 2, bolt, 3, the outer ring, 4, tapper, 5, bolt, 6, centre circle upper slice, 7, tapper, 8, bolt, 9, the inner ring gear teeth, 10, tapper, 11, roller, 12, sheet under the centre circle, 13, roller, 14, tapper, 15, inner ring.Be characterized in having between the sheet 12 and outer ring 3 under centre circle upper slice 6, the centre circle three row's tapper raceways, be respectively charged into tapper 4, tapper 10, roller 11 in three row's raceways, three row's tapper raceways are arranged between sheet 12 and the inner ring 15 under centre circle upper slice 6, the centre circle, be respectively charged into tapper 7, roller 13, tapper 14 in three row's raceways; Sheet 12 is with bolt or screw attachment under centre circle upper slice 6 and the centre circle, and the centre circle that forms after sheet 12 combinations under centre circle upper slice 6 and the centre circle is connected by the flange about the supporting main frame of bolt 5 and pivoting support.
From Fig. 2, bolt 2, bolt 5, bolt 8 can be two rows, and rolling element all is the tapper form, separates with spacing block between the rolling element.
Outer ring 3 comprises the outer ring gear teeth 1, and anodontia two kinds of forms; Inner ring 15 comprises the inner ring gear teeth 9, and anodontia two kinds of forms; Outer ring 3 and inner ring 15 are respectively to have tooth and to arrange in pairs or groups arbitrarily without tooth pattern;
The utility model is rational in infrastructure, saves cost, realizes easily, can effectively solve traditional pivoting support problem that axial dimension amplifies because satisfying larger bearing capacity, and its bearing capacity is compared with common three organ timbering formula pivoting supports and improved more than 200%.For the expansion of pivoting support application provide may, can well be used at various heavy rotary mechanisms.
