Abstract
The invention provides a jet-type bearing, which comprises an inner ring, an outer ring, a rolling element and a retainer. The bearing per se is arranged in a relatively sealed protection shell; the outer ring is provided with a saw-toothed edge; one side of the outer ring is provided with a fluid jet orifice; the 180 to 360-degree side of a small hole of the outer ring is provided with a plurality of small hole outlets; the bearing can rotate under the pushing generated by the pressure difference between the big holes and the small holes; and the saw-toothed edge also can be used for stopping. The invention has the advantages that the common bearing is improved and the big holes and the small holes are arranged on the common bearing so that the bearing rotates under the action of the pressure difference of the jet fluid between the big holes and the small holes; if the bearing has higher requirement on the rotating speed, the electricity assistance also can be carried out on the bearing; and the bearing not only is suitable to be used on the water, but also can be used under the water, and also reasonably utilizes the underwater pressure energy.
Description
Technical field
The present invention relates to a kind of bearing, especially a kind of jet-type bearing.
Background technique
Bearing is the fixed member in the machinery.When other parts produce relative movement each other on axle, be used for retainer shaft the central position and control the parts of this motion, just be referred to as bearing.
Study carefully it and be used for saying be to support, promptly literal interpretation is used for holding axle, but this is the part of its effect, supports its essence and can bear radial load exactly.Also can be understood as it and be used for fixing axle.Be exactly that stationary axle makes it can only realize rotating, and control its moving axially and radially.It is exactly can not work that motor does not have the consequence of bearing at all.Because axle may be to the motion of any direction, and require axle to rotate during machine operation.Can not realize the effect of transmission theoretically, moreover, bearing also can influence transmission, must realize good lubricating in order to reduce this influence on the bearing of high speed shaft, the bearing that has itself has had lubricated, is called prelubricated bearing, and most bearing must have lubricant oil, be responsible for when running up, because friction not only can increase energy consumption, more fearful is to be easy to damage bearing.The saying that sliding friction is changed into rolling friction is unilateral, because kind of a thing that is sliding bearing is arranged.Under certain loading, revolution that bearing is experienced before spot corrosion occurring or hour number are called bearing life.Since accuracy of manufacturing, the difference of material uniformity coefficient, even same material, the same a collection of bearing of same size uses under same operating conditions, its life-span length is also inequality.For determining the standard of bearing life, bearing life and reliability are connected.
But, also need in the industry much to have specific characteristics can and the bearing of profile, to satisfy different industrial needs.
Summary of the invention
At the problems referred to above, the invention provides a kind of jet-type bearing.
A kind of jet-type bearing; comprise inner ring, outer ring, rolling element, retainer; it is characterized in that bearing self is contained in the airtight relatively containment vessel; its outer ring is provided with the flexuose edge; one side of outer ring is provided with a fluid jet mouth; 180 ° of-360 ° of sides at the outer ring aperture are provided with a plurality of little hole exits, and bearing just can be rotated under the promotion of pressure difference between the big aperture, and the flexuose edge can also be used for stop.
Remarkable result of the present invention is that common bearing is improved, be provided with big aperture thereon, make bearing under the action of pressure of the jet fluid between the big aperture, be rotated, if rotating speed is had relatively high expectations, can also assist by electricity, be not only applicable to waterbornely, can also be used under water, but also reasonable use the pressure energy under water.
Embodiment
Below the present invention will be further described: bearing self is contained in the airtight relatively containment vessel; its outer ring is provided with the flexuose edge; one side of outer ring is provided with a fluid jet mouth; 180 ° of-360 ° of sides at the outer ring aperture are provided with a plurality of little hole exits; bearing just can be rotated under the promotion of pressure difference between the big aperture; the flexuose edge can also be used for stop, and therefore, bearing just can be rotated or speed governing under the promotion of pressure difference between the big aperture.
Apply the present invention in the mechanical system, common bearing is improved, be provided with big aperture thereon, make bearing under the action of pressure of the jet fluid between the big aperture, be rotated, if rotating speed is had relatively high expectations, can also assist by electricity, be not only applicable to waterborne, can also be used under water, but also reasonable use the pressure energy under water.
Claims (3)
