Abstract
The utility model provides a decelerating bearing comprises inner circle, spill outer lane and speed reduction rotor, and the speed reduction rotor is formed by connecting with its axis both ends two symmetrical less rotors of diameter a great rotor of diameter, and speed reduction rotor diameter major part falls into in the recess of spill outer lane, and with inner circle in close contact with, the less part frame of diameter is on two holding surfaces of spill outer lane to reduced the friction loss between them, increased decelerating bearing's life has prolonged maintenance cycle, also makes its rotation light more smooth and easy simultaneously.
Description
Art
The utility model relates to a kind of bearing that can increase working life in mechanical transmission fields.
Background technique
Along with the development of modern industry, the machinery of high speed rotating gets more and more, and proposes very high request to the quality of bearing.
Model utility content
The utility model provides a kind of bearing that can increase working life when material is constant, described bearing mountain inner ring, spill outer ring and deceleration rotor composition.
To be deceleration rotor be one of technological scheme that the utility model adopts is formed by connecting by the rotor that two diameters of the larger rotor of diameter and its axis two ends symmetry are less, and diameter major part and smaller portions can be the shape such as cylinder, circular cone.
Two of the technological scheme that the utility model adopts is outer ring cross-sections of bearing is spill, its recessed large and small semidiameter being deeply greater than deceleration rotor.
Three of the technological scheme that the utility model adopts is that bearing inner race contacts with the diameter major part of deceleration rotor, and two supporting surfaces of spill outer ring contact with the smaller-diameter portion of deceleration rotor.
The utility model beneficial effect in use has both added the working life of bearing, bearing can be made again to rotate lighter, smooth and easy.In addition, because the bottom portion of groove of outer ring can have lubricant oil at relatively long time memory, this also just extends the curing cycle of bearing.
Accompanying drawing explanation
For cylindrical deceleration rotor.
Fig. 1 is section of structure of the present utility model;
Fig. 2 is structural front view of the present utility model;
In accompanying drawing, each reference character represents respectively: (1) inner ring, (2) spill outer ring, (3) deceleration rotor.
Embodiment
As shown in Figure 1, the diameter major part of deceleration rotor 3 is trapped in the groove of spill outer ring 2, with inner ring 1 close contact; Smaller-diameter portion frame is on two supporting surfaces of spill outer ring 2.Because two-part of deceleration rotor 3 contact with inner ring 1, spill outer ring 2 respectively, thus compare with traditional bearing rotor and just decrease friction point, also just decrease the frictional loss of rotor self.
As shown in Figure 2, when inner ring 1 rotates counterclockwise, with the point of contact of rotor 3 smaller-diameter portion and the spill outer ring 2 liang of supporting surfaces that slow down for axle, the frictional resistance force brachium that inner ring 1 drives deceleration rotor 3 to rotate is R
greatly+ R
little, the long R of the gravity arm of force of rotor 3
little, both ratios are (R
greatly+ R
little)/R
littleand the ratio of both traditional bearings is 2R/R, speed reduction bearing ratio between two is greater than traditional bearing ratio between two, so according to lever principle, inner ring 1 drives deceleration rotor 3 to rotate required frictional force and is less than frictional force needed for traditional bearing, therefore just reduce inner ring 1 and deceleration rotor 3 diameter and turn frictional loss between major part, also make inner ring 1 rotate lighter smooth and easy simultaneously.
As shown in Figure 1 and Figure 2, two-part of deceleration rotor 3 are integrative-structures, during rotation, two-part outer rim has identical angular velocity, but because its diameter is different, make the linear velocity of deceleration rotor 3 smaller-diameter portion outer rim less, thus just reduce the frictional loss between unit time inner concave shape outer ring 2 and deceleration rotor 3 smaller-diameter portion; It is same because deceleration rotor 3 smaller-diameter portion border line speed is less, the revolution speed of deceleration rotor 3 entirety is reduced, the centrifugal force produced also reduces thereupon, the pressure of deceleration rotor 3 smaller-diameter portion to the 2 liang of supporting surfaces in spill outer ring also reduces, and this further reduces again the frictional loss between them.
In sum, by reducing the frictional loss between each parts of speed reduction bearing, both adding the working life of speed reduction bearing, having extended curing cycle, and also made its rotation more light smooth and easy simultaneously.
