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
The invention belongs to a kind of pivoting support, specifically belong to a kind of pivoting support that is applicable to the big especially occasion of load.
Background technique
The tradition single-row ball type, the decussation roller formula, biserial ball formula, three organ timbering formula pivoting supports can be selected bigger rolling element for use for satisfying bigger load, perhaps increase by a row rolling element, thereby make axial dimension bigger.Along with the field that pivoting support uses is more and more wider, applied host performance is increasingly high, 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 short relatively.Main frame can not unrestrictedly simple size amplify when machinery maximizes, must carry out rational structure to supporting various parts and improve, to satisfy the demand of growing high-performance mechanical.
Summary of the invention
The purpose of this invention is to provide a kind of pivoting support that is applicable to the big occasion of load.
For realizing above-mentioned purpose, the present invention 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, passes through bolt between centre circle top and the bottom; Between inner ring and the centre circle, three row's tapper raceways are respectively arranged between centre circle and the outer ring, all put 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, in its plane of rotation, have added the three rows rolling element (tapper) of symmetry with it, and this kind structural type has following advantage: 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 bolt row number, 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 under the situation of relatively-stationary axial dimension, can bear the purpose of bigger load.This is confirmed in the computer finite element analysis.
Description of drawings
Fig. 1 is one of structural representation of the present invention's six row's tapper formula pivoting supports.
Fig. 2 be the present invention six row tapper formula pivoting supports structural representation two.
Among the figure: 1, sheet 13, roller 14, tapper 15, inner ring under the outer ring gear teeth 2, bolt 3, outer ring 4, tapper 5, bolt 6, centre circle last slice 7, tapper 8, bolt 9, the inner ring gear teeth 10, tapper 11, roller 12, the centre circle.
Embodiment
Fig. 1 and Fig. 2 are the revolution section of pivoting support; By Fig. 1 and shown in Figure 2, six row's tapper roller type pivoting supports comprise outer ring 1, the outer ring gear teeth, 2, bolt, 3, the outer ring; 4, tapper, 5, bolt, 6, centre circle last 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 last 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 last 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 last slice 6 and the centre circle, and the centre circle that sheet 12 combination backs form under centre circle last slice 6 and the centre circle is connected through the flange about the supporting main frame of bolt 5 and pivoting support.
From Fig. 2, bolt 2, bolt 5, bolt 8 can be a row or 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 no tooth pattern to arrange in pairs or groups arbitrarily.
The present invention is rational in infrastructure, practices thrift cost, realizes easily, can effectively solve traditional pivoting support problem that axial dimension amplifies because satisfying bigger 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 maybe, can well be used at various heavy rotary mechanisms.
