Abstract
The invention discloses a crowned teeth slewing bearing which consists of an outer ring, an oil cup, an upper seal, a rolling body, an isolation block, an inner ring, an upper seal, a plug and tapered pin, and is characterized in that the teeth parts are all crowned teeth, a reference circle line excised from the axial section of the teeth parts is a section of arc, the circle is a displacement circle, the displacement circle is spherical, and the tooth profile of the excised section of the reference circle is in a waist drum shape. The slewing bearing structure is novel, the bearing capacity is strong, and the phenomenon of teeth breaking in use of the slewing bearing is reduced.
Description
Technical field
The invention belongs to a kind of novel pivoting support, relate in particular to the crowned teeth pivoting support.
Background technique
At present, most pivoting support gear ring tooth portion or be straight-tooth, or for boring tooth, it is the pivoting support of crowned teeth that tooth portion is not arranged as yet.
Summary of the invention
The purpose of this invention is to provide a kind of pivoting support gear ring tooth portion is the pivoting support of crowned teeth.This pivoting support novel structure, bearing capacity is strong, and reduces the broken teeth phenomenon in the pivoting support using process.
The objective of the invention is to realize like this: said crowned teeth pivoting support is made up of outer ring, lubricating cup, upward sealing, rolling element, spacing block, inner ring, upward sealing, obstruction and taper pin; The tooth portion that is characterized in said pivoting support is crowned teeth; The standard pitch circle line that excises on its tooth portion shaft section is one section circular arc; This circle is referred to as the displacement circle, and this displacement circle is sphere, and the flank profil of standard pitch circle sectility face is dolioform.
Tooth portion is the external tooth type pivoting support of straight-tooth and crowned teeth, and both differences are: tooth portion is the external tooth type pivoting support of straight-tooth, and the flank profil of its standard pitch circle sectility face is a straight line, and its top circle and root circle shaft section profile also are straight line; Tooth portion is the external tooth type pivoting support of crowned teeth; Owing to receive the restriction of processing conditions; The standard pitch circle line that excises on its shaft section is one section circular arc, and this circle is referred to as the displacement circle, and this displacement circle is sphere; The flank profil of standard pitch circle sectility face is dolioform, and its top circle and root circle shaft section profile are one section circular arc.
Tooth portion is the internal gear type pivoting support of straight-tooth and crowned teeth, and both differences are: tooth portion is the internal gear type pivoting support of straight-tooth, and the flank profil of its standard pitch circle sectility face is a straight line, and its top circle and root circle shaft section profile also are straight line; Tooth portion is the internal gear type pivoting support of crowned teeth; Owing to receive the restriction of processing conditions; The standard pitch circle line that excises on its shaft section is one section circular arc, and this circle is referred to as the displacement circle, and this displacement circle is sphere; The flank profil of standard pitch circle sectility face is dolioform, and its top circle and root circle shaft section profile are one section circular arc.
The crowned teeth pivoting support is applicable to the pivoting support of any face shaping.
The rolling element of crowned teeth pivoting support is applicable to any type of structure, comprising structural types such as single-row ball type, biserial ball formula, decussation roller formula, goalpost formula, three organ timbering formulas.
Its raceway end surface shape of crowned teeth pivoting support can be structural types such as peach shape, square, ellipse.
Pivoting support novel structure of the present invention can significantly improve bearing capacity, and institute's torque transmitted can improve 15 ~ 20% than straight-tooth; The angular displacement compensation rate is big, and when radial displacement equalled zero, the angular displacement allowable of spur type pivoting support was 1 °; And the angular displacement allowable of drum-shaped tooth type pivoting support be 1 ° 30 '; Improve 50%, under identical modulus, the number of teeth, the facewidth, crowned teeth is bigger than the angular displacement that straight-tooth allows; Drum-shaped tooth is regulated the contact of inside and outside tooth and is improved, and has avoided straight-tooth increment seamed edge extruding under the angular displacement condition, and stress is concentrated increment, has improved gear tooth friction, wear condition simultaneously, has reduced noise, and service cycle is long; Gear ring increment flare shape makes inside and outside tooth mounting or dismounting very convenient; The transmission efficiency of gear high 99.7%.During with the gear engagement that cooperates, sideshake is bigger than general gear transmission, can improve the pressure distribution on the Surface of action, can increase relative angular displacement allowable, and reduces the broken teeth phenomenon in the pivoting support using process.
Combine accompanying drawing and embodiment that crowned teeth pivoting support proposed by the invention is described further at present.
