Abstract
A thrust deep-groove ball slewing bearing belongs to slewing bearings, and comprises an upper clamping ring, a lower clamping ring, steel balls and isolation blocks, wherein the steel balls and the isolation blocks are arranged between the upper clamping ring and the lower clamping ring and are arranged at intervals; the shape of the steel balls is the same as that of the isolation blocks; steel ball rolling paths are arranged on the upper clamping ring and the lower clamping ring; and oil troughs are formed at the bottom ends of the steel ball rolling paths; and the contact angle between an upper clamping ring steel ball track and a lower clamping ring steel ball track is 90 degrees. The difference between the internal diameter dimension and the external diameter dimension of the slewing bearing is reduced, and the contact angle is 90 degrees, that is, the intersection angle between the force transferring direction of the rolling body and the radial plane of the slewing bearing is 90 degrees. The thrust deep-groove ball slewing bearing has the advantages that the structure space is small, the rotational moment is small, the bearing axial force is large, and the processing technology of the upper clamping ring and the lower clamping ring is simple; and when assembly is conducted, the assembly of the upper and the lower clamping rings and the steel balls is convenient.
Description
Technical field
The utility model relates to a kind of pivoting support, particularly a kind of thrust zanjon bobbin type pivoting support.
Background technique
At present, the pivoting support structural type that domestic pivoting support industry is produced is that outer rolling ring and interior rolling ring are rotated mutually by steel ball, is divided into single four-point contact ball formula, single decussation roller formula, double row reducing ball formula, three row's roller types.Wherein single four-point contact ball formula, wrapping angle≤50 °.Above-mentioned pivoting support is applicable to that structure space is big, pivoting moment big, the little occasion of carrying axial force, can satisfy the usage requirement of most situations, but little for structure space, pivoting moment is little, carrying axial force big occasion, the structural type of existing pivoting support just can not satisfy this requirement.Be mainly used in the machine for ring rolling mill in the metallurgical machinery, manually the revolution position of rotating machinery.
The model utility content
The purpose of this utility model is to provide a kind of: thrust zanjon bobbin type pivoting support, the pivoting support that solves present technology can not be applicable to that structure space is little, pivoting moment is little, the big problem of carrying axial force.
The purpose of this utility model is achieved in that this pivoting support comprises trim ring, lower clamping ring, steel ball and spacing block, steel ball and spacing block are arranged between last trim ring and lower clamping ring, steel ball and spacing block are spaced apart, the shape of steel ball and spacing block is identical, on last trim ring and lower clamping ring, steel ball rolling channel is arranged, oil groove is arranged in the bottom of the raceway of steel ball.
The described wrapping angle of going up the steel ball track of trim ring and lower clamping ring is 90 °.
Beneficial effect: owing to adopted such scheme, trim ring and lower clamping ring in the employing, between last trim ring and lower clamping ring, steel ball is arranged, spacing block is arranged between steel ball, spacing block and steel ball are intervally arranged, the inside and outside footpath difference in size of this pivoting support is reduced, and wrapping angle is 90 °, and promptly the power transmission direction of rolling element and the angle of cut between the pivoting support radial plane are 90 °; Guarantee about the diameter deviation 0.05mm at raceway center smooth and steel ball assembling when assembling.The ring raceway of rolling ring guarantees the conformity of 90 ° of radius of curvature and wrapping angles up and down, and the pivoting support that has solved present technology can not be applicable to that structure space is little, pivoting moment is little, the big problem of carrying axial force, has reached the purpose of this utility model.
Advantage: structure space is little, pivoting moment is little, the carrying axial force is big, and the technology of last trim ring and following circle processing is simple; Assembly when assembling, last trim ring and lower clamping ring and steel ball easy to assembly.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Among the figure, 1, go up trim ring; 2, lower clamping ring; 3, erection opening; 4, steel ball; 5, oil groove.
Embodiment
Embodiment 1: this pivoting support comprises trim ring 1, lower clamping ring 2, steel ball 4 and spacing block, between last trim ring 1 and lower clamping ring 2, steel ball 4 and spacing block are arranged, steel ball 4 and spacing block are spaced apart, the shape of steel ball 4 and spacing block is identical, on last trim ring 1 and lower clamping ring 2, steel ball rolling channel is arranged, oil groove 5 is arranged in the bottom of the raceway of steel ball.
The described wrapping angle of going up the steel ball track of trim ring 1 and lower clamping ring 2 is 90 °.
Steel ball by filling between last trim ring 1 and the lower clamping ring 2 joins together, and rotates mutually by steel ball.And the spacing block of packing between every steel ball is to avoid producing friction between the steel ball.
Claims (2)
1. thrust zanjon bobbin type pivoting support, it is characterized in that: this pivoting support comprises trim ring, lower clamping ring, steel ball and spacing block, steel ball and spacing block are arranged between last trim ring and lower clamping ring, steel ball and spacing block are spaced apart, the shape of steel ball and spacing block is identical, on last trim ring and lower clamping ring, steel ball rolling channel is arranged, oil groove is arranged in the bottom of the raceway of steel ball.
