Abstract

The invention provides a special bearing, which comprises inner rings, outer rings, rolling bodies and a cage, wherein the bearing is divided into two parts, including an internal bearing and an external bearing; the internal bearing is an ordinary deep groove ball bearing; the internal bearing is inlaid inside the external bearing; the outer ring of the internal bearing is the inner ring of the external bearing; the plane of the outer ring of the external bearing is an inclined tangent plane; the rolling bodies are spherical rollers; and the inside diameter of the rolling bodies of the internal bearing and the external bearing can be selected according to need. The whole bearing can bear radial force, axial force and irregular force in other directions. The special bearing has the significant effect of improving the ordinary deep groove ball bearing and sleeving the bearing with a roller bearing, and as the outer ring is in the shape of the inclined tangent plane, the bearing can bear not only radial force but also axial force and the force in the other directions, and can be used in special occasions with high requirements for bearings.

Description

A kind of special bearing

Technical field

The present invention relates to a kind of bearing, especially a kind of special 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 special bearing.

A kind of special bearing, comprise inner ring, the outer ring, rolling element, retainer, it is characterized in that bearing is divided into two parts, comprise an internal bearings and an external bearings, internal bearings is common deep groove ball bearing, internal bearings is nested in external bearings inside, the outer ring of internal bearings is the inner ring of external bearings, the plane, outer ring of external bearings is an inclination tangent plane shape, its rolling element is the spheroidal roller, the rolling element internal diameter of internal bearings and external bearings can be selected according to needs, but whole bearing bearing radial force, axial force and other directions are irregular stressed.

Remarkable result of the present invention be with common be that deep groove ball bearing improves, the nested again roller bearing in the outside of bearing, and its outer ring is for being inclination tangent plane shape, make the bearing not only can bearing radial force, axial force and other direction power can also be born, the special occasions that bearing is had relatively high expectations can be used for.

Embodiment

Below the present invention will be further described: bearing is divided into two parts, comprise an internal bearings and an external bearings, internal bearings is common deep groove ball bearing, internal bearings is nested in external bearings inside, the outer ring of internal bearings is the inner ring of external bearings, the plane, outer ring of external bearings is an inclination tangent plane shape, the angle of inclination of tangent plane can be arranged between 30 °-90 °, its rolling element is the spheroidal roller, can bear axial force, the rolling element internal diameter of internal bearings and external bearings can be selected according to needs, but whole bearing bearing radial force, axial force and other directions are irregular stressed.

Apply the present invention in the mechanical system, with common be that deep groove ball bearing improves, the nested again roller bearing in the outside of bearing, and its outer ring is for being inclination tangent plane shape, make the bearing not only can bearing radial force, axial force and other direction power can also be born, the special occasions that bearing is had relatively high expectations can be used for.
