Abstract
The utility model discloses a dual-roller revolving support, which comprises an inner ring and an outer ring, wherein the inner side wall of the outer ring is provided with an upper arc-shaped groove and an lower right-angle grooves; a steel ball is arranged in the arc-shaped groove; a roller is arranged in the right-angle groove; the outer wall of the inner ring is provided with a neck; the bottom surface of the neck is provided with an oil storing groove; the outer ring is arranged in the neck; and the side wall of the inner ring is communicated with an oil injecting channel. The dual-roller revolving support has the advantages of increased load capacity, working stability and low noise.
Description
Technical field
The utility model relates to a kind of pair of roller pivoting support.
Background technique
Pivoting support is a kind of large size bearing that can bear combined load, can bear simultaneously larger axially, radial load and tilting moment, pivoting support is again turntable bearing, some people also is called: the rotary support supporting of holding, circle round, pivoting support is used very extensive in real industry, be called by people: " joint of machine " is need do relative rotation motion between the two articles, need bear simultaneously again the mechanical necessary important transmission part of axial force, radial force, tilting moment.Along with developing rapidly of machinery industry, pivoting support is widely used in industries such as ship equipment, engineering machinery, light industry and machinery, metallurgical machinery, medical machinery, industrial machineries.
There is complex structure in the pivoting support of prior art, installs and uses inconvenience, and the defective such as carrying capacity is low.
The model utility content
The utility model provides a kind of carrying capacity to increase working stability, two roller pivoting supports that noise is little.
The utility model technical solution problem provides following scheme:
A kind of pair of roller pivoting support, comprise inner ring, outer ring, it is characterized in that: the madial wall of described outer ring is provided with arc groove, lower right angle groove, be provided with steel ball in the described arc groove, in the described right angle groove roller is installed, the outer wall of described inner ring is provided with draw-in groove, and the bottom surface of described draw-in groove is provided with oil storage tank, described outer ring is installed in the draw-in groove, is communicated with the oiling passage on the sidewall of described inner ring.
Be respectively equipped with bolt mounting holes on described outer ring, the inner ring.
The utility model has increased a roller on the basis of traditional pivoting support, the carrying capacity of floating bearing has just increased like this, and compares original pivoting support by such improvement like this, and more stable, noise is little.
