Description
Technical field
The utility model relates to axle support structure, in particular for the axle support structure of the output shaft of supporting motor.
Background technique
In general rotating machinery, along with the rising of temperature, the volume of axle can expand, and makes the shaft shoulder move to bearing inner race.And traditional bearing washer mostly is non-resilient packing ring.Non-resilient packing ring structurally is against on the bearing outer ring, and very little with the deformation of variation of temperature generation.Thus, make the bearing both sides be squeezed.So the pretightening force of bearing can become greatly, and bigger pretightening force will make reduce the working life of bearing, and can make machinery produce bigger noise.
The model utility content
The utility model becomes big technical problem for the pretightening force Yin Wendu that solves bearing traditionally rises, and a kind of axle support structure is provided, and it can make the pretightening force of bearing can Yin Wendu not rise and become big.
The utility model solves the problems of the technologies described above by the following technical solutions.

As the optimal technical scheme of axle support structure of the present utility model, described packing ring has annular flange flange, and described fitting seat has circular groove, and described annular flange flange is embedded in the described circular groove.
As the optimal technical scheme of axle support structure of the present utility model, the axial width of described circular groove is 5 to 10 millimeters.
As the optimal technical scheme of axle support structure of the present utility model, described packing ring has annular protrusion, and the described annular protrusion axis from described annular flange flange along described running shaft integratedly extends, and described annular protrusion is pressed on the outer ring of described bearing.
As the optimal technical scheme of axle support structure of the present utility model, described bearing is a ball bearing.
As the optimal technical scheme of axle support structure of the present utility model, described bearing is a roller bearing.
As the optimal technical scheme of axle support structure of the present utility model, described packing ring is a rubber parts.
Compare with traditional axle support structure, in the axle support structure of the present utility model, described packing ring is an elastic component, and Volume Changes that can absorption axes makes the pretightening force of bearing can Yin Wendu not rise and become big.
In conjunction with the drawings, read following detailed description, can further understand other advantage of the present utility model, feature and aspect specific embodiment of the utility model.
Description of drawings
Fig. 1 is the cut-away illustration according to an embodiment's of the present utility model axle support structure.
Embodiment
Clearer for technical problem, technological scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to the accompanying drawings embodiment of the present utility model is elaborated.Herein, same reference numerals is represented the same composition part.
As shown in Figure 1, the axle support structure of present embodiment comprises running shaft 100, fitting seat 200, bearing 400 and packing ring 300.Wherein, described fitting seat 200 has mounting hole 220.Described bearing 400 and described packing ring 300 are arranged in the described mounting hole 220.Described running shaft 100 has the shaft shoulder 110, and described bearing 400 has inner ring 410, roller 420 and outer ring 430.Described bearing 400 and described packing ring 300 are set on the described running shaft 100, and described bearing 400 is between the described shaft shoulder 110 and described packing ring 300.The described shaft shoulder 110 is pressed on the inner ring 410 of described bearing 400.
Wherein, described packing ring 300 is an elastic component.Because described packing ring 300 be elastic component, rather than adopts metal washer as conventional art, so Volume Changes that can absorption axes makes the pretightening force of bearing can Yin Wendu not rise and become greatly.
Furthermore, described packing ring 300 has annular flange flange 310, and described fitting seat 200 has circular groove 210, and described annular flange flange 310 is embedded in the described circular groove 210.Wherein, the axial width of described circular groove 210 is 5 to 10 millimeters.Thus, can guarantee that bearing washer 300 can not be extruded in operation process comes off.
Furthermore, described packing ring 300 has annular protrusion 320, and described annular protrusion 320 axis from described annular flange flange 310 along described running shaft 100 integratedly extends, and described annular protrusion 320 is pressed on the outer ring 430 of described bearing 400.Described packing ring 300 part that is formed in one.
Wherein, described bearing 400 is a ball bearing.Perhaps, described bearing 400 is a roller bearing.
In axle support structure of the present utility model, described packing ring 300 is preferably rubber parts.Because having with temperature, rubber raises and the characteristic of deliquescing, so become the ideal material of this bearing washer 300.In addition, because packing ring 300 works under high temperature and Oil Lubrication Condition, so this material should have the characteristic of heatproof and oil resistant.Because this packing ring 300 withstands on the bearing outer ring 430, both do not have slide relative, so the wear resistance of material is not had specific (special) requirements.
According to axle support structure of the present utility model, when axle begins to expand and when causing bearing pre-fastening to increase, because the hardness of bearing washer 300 is lower, thereby when making at high temperature, axle 100 and bearing 400 can move to a direction simultaneously, can not push the situation of bearing 400, also just can not cause the excessive of the increase of internal stress of axle 100 and bearing 400 pretightening forces, this had both improved the axle and the working environment of bearing, also reduced the noise of integral mechanical structure.
When machine (for example motor) was worked, packing ring 300 applied certain pretightening force for bearing 400, and when temperature raise, axle 100 expanded and packing ring 300 deliquescing.
Because this packing ring 300 has certain plastic deformation, so allow packing ring 300 be subjected to one during assembling earlier along the power (for example using clamp to clamp protruding part) of cylindrical in circle, make packing ring 300 diminish, put bearing chamber then into, time bearing chamber, unclamp external force, so just can be so that packing ring 300 is put in the circular groove 210 naturally, according to such structure, packing ring 300 can be securely fixed in the fitting seat 200.
Adopt the bearing washer 300 of such scheme, can effectively increase the working life of bearing 400, and because the axial float of axle 100, can clash into peripheral component, thereby generation noise, and adopt this adaptive bearing washer 300, not only reduce the noise of bearing 400, and reduced the axial float noise of axle 100.This packing ring 300 especially can be used for the middling speed axle, and for high speed shaft, this bearing washer 300 does not have the reliable performance of metal bearing packing ring.
Those skilled in the art know easily; the above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.Protection domain of the present utility model is determined by claims.
