Abstract
The invention discloses a bearing seat balance structure. The structure comprises a rotating shaft which is internally rotationally connected with a bearing seat, wherein the rotating shaft protrudes out of the bearing seat to form a balance section; a balance sleeve is connected onto the balance section; an end surface plate capable of limiting the balance sleeve in the axial direction is fixed on the end surface of the balance section through screws; an annular balance sleeve seat is arranged on the balance sleeve in the radial direction; the balance sleeve seat comprises an annular boss which extends inwardly and is located between the balance sleeve and the end surface plate; a gap of 10 mm is reserved between the balance sleeve seat and the balance sleeve; a gap of 5 mm is reserved between the annular boss and the balance sleeve. As the rotating shaft protrudes out of the bearing seat to form the balance section, load on the two sides of the bearing seat can be balanced and the problem of abrasion caused by uneven stress is solved.
Description
Technical field
The present invention relates to a kind of equilibrium structure, be specifically related to a kind of bearing support equilibrium structure.
Background technique
Bearing support is a kind of device that can accept combined load, particularly in some main equipments, needs to arrange special bearing support, for bearing radial load.For in some main equipments, the bearing support installed needs be equipped with special equilibrium structure, for the moment of gentle bearing support both sides, avoid that bearing support is one-sided bears larger load, accelerate the wearing and tearing of bearing support, reduce working life.
Summary of the invention
The object of the present invention is to provide a kind of bearing support equilibrium structure, comparatively large for solving main equipment bottom bracket monotonic lateral loading, the problem of unbalance stress wearing and tearing.
For achieving the above object, technological scheme of the present invention is: bearing support equilibrium structure, comprise the rotating shaft be rotationally connected in bearing support, described rotating shaft stretches out in bearing support and forms balancing segment, on described balancing segment, key is connected with balancing sleeve, the end face of described balancing segment is fixed with the end plates of axial limiting balance sleeve by screw, the radial direction of described balancing sleeve is provided with the balance set cylinder base of annular, described balance set cylinder base includes an annular boss extended internally, described annular boss is between balancing sleeve and end plates, the gap of described balance set cylinder base and balancing sleeve is 10mm, the gap of described annular boss and balancing sleeve is 5mm.
When adopting technique scheme, rotating shaft stretches out in bearing support and forms the effect that balancing segment can play trunnion shaft bearing both sides load, solves the problem of unbalance stress wearing and tearing.Moreover, be provided with balance set cylinder base, effective support can be played to balancing segment by balance set cylinder base, the effect of constraint can be played when the obvious stress deformation of balancing segment.Balance set cylinder base can add solid lubrication fat, play the effect reducing friction.By the annular boss that balance set cylinder base extends internally, the effect of axial limiting can be played to balancing sleeve.
Further, be provided with a lining ring on described balancing sleeve and between balance set cylinder base, described lining ring is fixed on balancing sleeve by sunk screw.By arranging lining ring, the direct friction between balancing sleeve and balance set cylinder base can be overcome, avoiding the gap of causing after wearing and tearing to increase, causing the problem of unbalance stress.And adopt dismountable lining ring, can also change separately when lining ring damages, provide cost savings.
Further, the cross section of described balancing segment is stepped shaft, and the stepped cross-section of described balancing sleeve inwall and balancing segment matches.Above-mentioned the effect can playing the movement of axial limiting balance sleeve is set.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of bearing support equilibrium structure embodiment of the present invention.
Embodiment
As shown in Figure 1, bearing support equilibrium structure of the present invention, the rotating shaft 1 be rotationally connected in bearing support 2, rotating shaft 1 stretches out in bearing support 2 and forms balancing segment.On this balancing segment, key is connected with balancing sleeve 3, and the end face of balancing segment is fixed with by screw the end plates 4 that axial limiting balance sleeve deviates from.The cross section of balancing segment is stepped shaft, and the inwall of balancing sleeve 3 and the stepped cross-section of balancing segment match.Above-mentioned the effect can playing the movement of axial limiting balance sleeve 3 is set.The radial direction of balancing sleeve 3 is provided with the balance set cylinder base 5 of balance support section, and this balance set cylinder base 5 includes an annular boss extended internally 51, and annular boss 51, between balancing sleeve 3 and end plates 4, can play the effect of axial limiting to balancing sleeve 3.Be provided with a lining ring 31 on balancing sleeve 3 and between balance set cylinder base 5, lining ring 31 is fixed on balancing sleeve 3 by sunk screw.Gap between balance set cylinder base 5 and lining ring 31 is d=10mm, be convenient to balancing segment at work follow-up motion time in the axial direction can trace play.Gap between described annular boss 51 and lining ring 31 is h=5mm, reserves the microvibration offset by gap of balancing segment.
Form because rotating shaft stretches out in bearing support 2 effect that balancing segment can play trunnion shaft bearing 2 both sides load, solve the problem of unbalance stress wearing and tearing.Moreover, be provided with balance set cylinder base 5, effective support can be played to balancing segment by balance set cylinder base 5, the effect of constraint can be played when the obvious stress deformation of balancing segment.Balance set cylinder base 5 can add solid lubrication fat, play the effect reducing friction.By the annular boss that balance set cylinder base 5 extends internally, the effect of axial limiting can be played to balancing sleeve 3.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
