Abstract
The invention provides a multistage multi-directional bearing, comprising only one common inner ring, outer rings, a rolling element and a cage, wherein the inner ring is provided with inner/outer ring tracks with different inner diameters, the inner diameter of the rolling element can be adjusted according to each different track, the inner ring is relatively fixed, the outer rings with different inner diameters can rotate in accordance with different speed rates and different directions, and the rolling element of the bearing can be roll ball, roller or other types of rolling element; the multistage multi-directional bearing has the obvious advantage that: the same inner ring of the bearing is provided with a plurality of outer rings with different inner diameters and each outer ring has own different rotating speed and direction, so adjustment can be performed as required, which can not only meet the demand of customer, but can also control a plurality of concentric bearings.
Description
Technical field
The present invention relates to a kind of bearing, especially a kind of multistage multi-directional 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 multistage multi-directional bearing.
A kind of multistage multi-directional bearing, comprise inner ring, outer ring, rolling element, retainer, it is characterized in that it has only a common inner ring, on inner ring, be provided with the Internal and external cycle track of different inner diameters, the internal diameter of its rolling element can be adjusted according to each different track, inner ring is relatively-stationary, and the outer ring of different inner diameters can be rotated with different directions according to different speed, and bearing roller can be the rolling element of ball, roller or other types.
Remarkable result of the present invention is that common bearing is improved, the outer ring of a plurality of different inner diameters is set on same bearing inner race, each outer ring has different rotating speeds and direction separately, can adjust according to needs, not only can satisfy a side needs, can also control a plurality of concentric bearings.
Embodiment
Below the present invention will be further described: bearing has only a common inner ring, on inner ring, be provided with the Internal and external cycle track of different inner diameters, the internal diameter of its rolling element can be adjusted according to each different track, inner ring is relatively-stationary, the outer ring of different inner diameters can be rotated with different directions according to different speed, and bearing roller can be the rolling element of ball, roller or other types.
Apply the present invention in the mechanical system, common bearing is improved, the outer ring of a plurality of different inner diameters is set on same bearing inner race, each outer ring has different rotating speeds and direction separately, can adjust according to needs, not only can satisfy a side needs, can also control, be particularly useful for bearing direction and rotating speed are had the occasion of multistage demand a plurality of concentric bearings.
