Abstract
The invention provides a speed reducing bearing which consists of an inner ring, a concave outer ring and a speed reducing rotor, wherein the speed reducing rotor is formed by connecting a rotating body having great diameter with two rotating bodies which have small diameters and are symmetrically arranged at the two ends of the axis of the speed reducing rotor; the rotating body having great diameter, of the speed reducing rotor, is hollowed in a groove of the of concave outer ring, and is in close contact with the inner ring; and the rotating bodies having small diameters, of the speed reducing rotor, are placed on two supporting surfaces of the concave outer ring. Thus, frictional loss between the rotating bodies is reduced; the service life of the speed reducing bearing is increased; a maintenance period is prolonged; and the speed reducing bearing can rotate more lightly and smoothly.
Description
Art
The present invention relates to a kind of bearing that can increase service life in mechanical transmission fields.
Background technology
Along with the development of modern industry, the plant equipment of high-speed rotation gets more and more, the quality of bearing is proposed very high request.
Summary of the invention
The present invention provides a kind of bearing that can increase service life in the case of material is constant, and described bearing is by inner ring, recessed
Shape outer ring and deceleration rotor composition.
One of the technical solution adopted in the present invention be deceleration rotor be symmetrical by a rotor being relatively large in diameter and its axis two ends
The less rotor of two diameters be formed by connecting, larger diameter portion and smaller portions can be in the shapes such as cylinder, circular cone.
The two of the technical solution adopted in the present invention be the outer ring cross-section of bearing be spill, its recessed deep large and small more than deceleration rotor
Semidiameter.
The three of the technical solution adopted in the present invention are that bearing inner race contacts with the larger diameter portion of deceleration rotor, spill outer ring
Two supporting surfaces contact with the smaller-diameter portion of deceleration rotor.
The present invention provides the benefit that in use, has both added the service life of bearing, bearing can be made again to rotate lighter,
Smooth and easy.Further, since the bottom portion of groove of outer ring can have lubricating oil at relatively long time memory, this most just extends bearing
Curing cycle.
Accompanying drawing explanation
As a example by cylinder deceleration rotor.
Fig. 1 is the section of structure of the present invention；
Fig. 2 is the structural front view of the present invention；
In accompanying drawing, each reference represents respectively: (1) inner ring, (2) spill outer ring, (3) deceleration rotor.
Detailed description of the invention
As it is shown in figure 1, the larger diameter portion of deceleration rotor 3 is trapped in the groove of spill outer ring 2, it is in close contact with inner ring 1；
Smaller-diameter portion frame is on two supporting surfaces of spill outer ring 2.Due to deceleration rotor 3 two parts respectively with inner ring 1, spill
Outer ring 2 contacts, thus compares with traditional bearing rotor and just decrease friction point, the most just decreases the frictional dissipation of rotor self.
As in figure 2 it is shown, when inner ring 1 rotates counterclockwise, with rotor 3 smaller-diameter portion and the support of 2 liang, spill outer ring of slowing down
The contact point in face is axle, and the frictional resistance force brachium that inner ring 1 drives deceleration rotor 3 to rotate is RGreatly+RLittle, the gravity arm of force of rotor 3
Long RLittle, both ratios are (RGreatly+RLittle)/RLittle, and the ratio of both traditional bearings is 2R/R, speed reduction bearing ratio between two is wanted
More than traditional bearing ratio between two, so according to lever principle, it is little that inner ring 1 drives deceleration rotor 3 to rotate required frictional force
Frictional force needed for traditional bearing, has therefore been reduced by inner ring 1 and frictional dissipation that deceleration rotor 3 diameter turns between major part,
Also make inner ring 1 rotate lighter smooth and easy simultaneously.
As shown in Figure 1 and Figure 2, two parts of deceleration rotor 3 are integrative-structures, and during rotation, two-part outer rim has identical
Angular velocity, but because its diameter is different, the linear velocity making deceleration rotor 3 smaller-diameter portion outer rim is less, thus has been reduced by list
Frictional dissipation between bit time concave shaped outer ring 2 and deceleration rotor 3 smaller-diameter portion；Same because of deceleration rotor 3 diameter
Smaller portions border line speed is less, makes the revolution speed of deceleration rotor 3 entirety reduce, and produced centrifugal force reduces the most therewith,
The pressure of the 2 liang of supporting surfaces in spill outer ring is also reduced by deceleration rotor 3 smaller-diameter portion, and this further reduces between them
Frictional dissipation.
In sum, by reducing the frictional dissipation between each parts of speed reduction bearing, both added the service life of speed reduction bearing,
Extend curing cycle, also make its rotation the lightest smooth and easy simultaneously.
