Abstract
The invention relates to the technical field of transmission parts, and in particular relates to a double-layer rolling bearing. The double-layer rolling bearing comprises an outer ring, a middle layer, a steel ball 1, an inner ring, a steel ball 2 and oil holes, wherein the steel ball 1 is arranged between the outer ring and the middle layer, the steel ball 2 is arranged between the middle layer and the inner ring, and the oil holes are formed in the outer ring and the inner ring. The double-layer rolling bearing has the advantages of simple, compact and reasonable structure, convenience and fastness in assembly and reliability in connection, reduces the cost of machinery installation, is conveniently installed and disassembled, and increases the lubricating effect. The service life of the bearing is prolonged, the working reliability of the bearing is greatly increased, and the bearing is easily used and popularized.
Description
Technical field
The present invention relates to a kind of technical field of driving component, especially a kind of double-layer rolling bearing.
Background technique
Existing bearing is installed and changes cumbersome, improved the cost of mechanical erection, and the fitting surface lubrication effect of axle and axis hole is poor, has shortened the working life of bearing, greatly reduces the reliability of bearing working.
Summary of the invention
In order to overcome the deficiency that existing bearing is installed and replacing bothers, installation cost is high, working life is short and functional reliability is low, the invention provides a kind of double-layer rolling bearing.
The technical solution adopted for the present invention to solve the technical problems is: a kind of double-layer rolling bearing, comprise outer ring, mesosphere, steel ball one, inner ring, steel ball two and oil hole, between outer ring and mesosphere, be provided with steel ball one, between mesosphere and inner ring, be provided with on steel ball Er， outer ring and inner ring and be equipped with oil hole.
The invention has the beneficial effects as follows, this double-layer rolling bearing is simple in structure, compact and reasonable, easy to assembly quick, connect reliably, not only reduced the cost of mechanical erection, and facilitated the installation and removal of bearing, promoted lubrication effect, extended the working life of bearing, greatly improved the reliability of bearing working, be easy to use and promote.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Figure ，2. mesosphere, Zhong1. outer ring, 3. steel ball one, 4. inner ring, 5. steel ball two, 6. oil hole.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of double-layer rolling bearing, comprise outer ring 1, mesosphere 2, steel ball 1, inner ring 4, steel ball 25 and oil hole 6, between outer ring 1 and mesosphere 2, be provided with steel ball 1, between mesosphere 2 and inner ring 4, be provided with steel ball 25, on outer ring 1 and inner ring 4, be equipped with oil hole 6.
Use between Shi， outer ring 1 and mesosphere 2 steel ball 1 is installed, between mesosphere 2 and inner ring 4, steel ball 25 is installed, on outer ring 1 and inner ring 4, be equipped with oil hole 6 and conveniently steel ball 1 and steel ball 25 carried out to oil injecting lubricating.This double-layer rolling bearing is simple in structure, compact and reasonable, easy to assembly quick, connect reliable, not only reduced the cost of mechanical erection, and facilitated the installation and removal of bearing, and promoted lubrication effect, extended the working life of bearing, greatly improved the reliability of bearing working, be easy to use and promote.
