Description
Technical field
This utility model relates to mechanism and rotates field, particularly relates to a kind of bearing.
Background technology
Under the occasion that high rotating speed, underloading and vibration are strong, higher to bearing requirements, for Mu Qian, existing solution is usually and uses elliptic bearing or circular journal bearing structure, but the sliding bearing disadvantage of both structures anti-interference stabilizing power in the case of underloading is poor, easily produce vibration if any microvariations.In the such as dragging system of rotor dynamics testing stand, small vibration will affect the test data precision of testing stand, so how can develop a solution jackshaft device bearing that anti-interference stability is high in the case of high rotating speed, underloading is the difficult problem that those skilled in the art have been working hard solve.
Summary of the invention
The purpose of this utility model is: overcome the above-mentioned problems in the prior art, a kind of bearing is proposed, by unique design, realize the tilting-pad bearing of seesaw structure by arranging ball cushion block between axle sleeve and bearing shell, solve the use requirement that jackshaft device anti-interference stability in the case of high rotating speed, underloading is high.
The purpose of this utility model is realized by following technical proposals:
A kind of bearing, including: axle sleeve and some bearing shells, there is in described axle sleeve the groove accommodating bearing shell, described bearing shell and axle sleeve bottom portion of groove joint are provided with ball cushion block, and described ball cushion block is fixed on bearing shell, and described bearing shell is connected with axle sleeve groove side.
A kind of bearing of the present utility model, described ball cushion block has sphere, and described sphere is provided with ball pad connecting hole, wears bolt and be connected with bearing shell in described pad connecting hole.
A kind of bearing of the present utility model, the quantity of described ball pad connecting hole is two, and on the same circular arc with the ball cushion block center of circle.
A kind of bearing of the present utility model, said two ball pad connecting hole is 165 degree with the angle of the line in the center of circle of place circular arc.
A kind of bearing of the present utility model, the bottom of described bearing shell groove is provided with some fuel feed holes, and described fuel feed hole is between adjacent two pieces of bearing shells.
A kind of bearing of the present utility model, the axial two ends of described bearing shell are provided with bearing shell connecting hole, wear bolt and realize being connected with axle sleeve in described bearing shell connecting hole.
A kind of bearing of the present utility model, the quantity of described bearing shell is 5.
A kind of bearing of the present utility model, described axle sleeve is formula Split type structure symmetrical above and below, is provided with pin and is bolted at described two-part structure.
A kind of bearing of the present utility model, is respectively arranged with lifting eye outside the upper and lower two parts of described axle sleeve.
According to technique scheme, the beneficial effects of the utility model are: overcome the above-mentioned problems in the prior art, a kind of bearing is proposed, by unique design, real by arranging ball cushion block between axle sleeve and bearing shell, such that it is able to make bearing shell can have the condition of buffering when by impacting, it is possible to adaptive adjustment, and the bearing shell of sectional type also allows for heat radiation, thus improve service life and the stability in use of bearing.
