Embodiment
This embodiment provides a kind of rotating-shaft support devices of cast stranding machine, and it can effectively avoid bearing to hold flimsy problem.This embodiment additionally provides a kind of cast stranding machine comprising above-mentioned rotating-shaft support devices.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the rotating-shaft support devices of a kind of cast stranding machine that this embodiment provides, for installing the rotating shaft 14 of cast twisted wire, comprises support, bearing pedestal 11 and self-aligning roller bearing 12 and thrust force aligning bearing 13.
Wherein, bearing pedestal 11 is fixedly installed on support, and the outer ring of self-aligning roller bearing 12 and thrust force aligning bearing 13 is fixed in described bearing pedestal 11, and the installation end fixed cover of rotating shaft 14 is loaded in the inner ring of self-aligning roller bearing 12 and thrust force aligning bearing 13.
Setting like this, the rotating-shaft support devices that this embodiment provides, at the beginning of cast stranding machine starts, the rotating speed of rotating shaft 14 is lower, and the radial forces suffered by rotating shaft 14 increases gradually, and now, self-aligning roller bearing 12 plays the effect of offsetting radial forces.
When the rotating speed along with rotating shaft 14 increases gradually, the axially loaded of rotating shaft 14 is comparatively large, and now, thrust force aligning bearing 13 is for offsetting axial force, and the axial force suffered by self-aligning roller bearing 12 is less.Therefore, the rotating-shaft support devices that the utility model provides, no matter at rotating speed height, the power suffered by rotating shaft 14 all can be balanced out by two different bearings, can not cause damage to bearing.
In addition, it should be noted that, during installation, the bearing axis of self-aligning roller bearing 12 and thrust force aligning bearing 13 coincides, and so the two is in engagement process, and the two component born distributes rationally, can improve the useful life of the two.
Particularly, self-aligning roller bearing 12 and thrust force aligning bearing 13 can be installed in the following way, and the end sleeve of rotating shaft 14 is connected to belt wheel 15, and belt wheel 15 rotates for driving rotating shaft 14.Can be provided with spacer 16 between self-aligning roller bearing 12 and belt wheel 15, rotating shaft 14 is fixed with the first clip 17, and the inner ring of self-aligning roller bearing 12 is clamped between spacer 16 and the first clip 17.
Rotating shaft 14 is also provided with the second clip 18 and the bearing (ball) cover being fixed on thrust force aligning bearing 13 both sides, and the second clip 18 is positioned at the inner side of thrust force aligning bearing 13 and offsets with its inner ring, and the outer ring of bearing (ball) cover and thrust force aligning bearing 13 offsets.
Setting like this, the integral layout of rotating-shaft support devices is reasonable, and thrust force aligning bearing 13 and self-aligning roller bearing 12 are fixed respectively, can not produce interaction force therebetween, avoid stressed influencing each other therebetween.In addition, self-aligning roller bearing 12 is arranged at the side near belt wheel 15, and thrust force aligning bearing 13 is arranged at the side near bobbin loader, first the radial load that belt wheel 15 produces can balance out by self-aligning roller bearing 12, reduce radial forces to the impact of thrust force aligning bearing 13, equally, first axial force can balance out by thrust force aligning bearing 13, reduce axial force to the impact of self-aligning roller bearing 12, further increase the useful life of the two.
In another preferred version of this embodiment, be provided with elastic component 19 between the outer ring of bearing (ball) cover and thrust force aligning bearing 13, elastic component 19 is in compressive state.Setting like this, elastic component 19 1 aspect can improve the axial endurance performance of thrust force aligning bearing 13, on the other hand, elastic component 19 acts on the active force of thrust force aligning bearing 13 all the time, can avoid when axial force or radial forces increase suddenly or reduce, the inner ring of thrust force aligning bearing 13 and outer ring occur the problem that fit clearance increases suddenly or diminishes suddenly further increasing the useful life of self-aligning bearing.
Further, bearing (ball) cover can be provided with groove, one end of elastic component 19 is positioned at groove.Setting like this, elastic component 19 has good stability.Above-mentioned elastic component 19 can be specially Compress Spring, certainly, also can be other elastic component 19, such as, and elastic etc.
In addition, in order to prevent dust or impurity from entering in bearing, the first sealing ring 20 can be provided with between bearing (ball) cover and described rotating shaft 14.Gland 21 can be provided with between spacer 16 and bearing pedestal 11, and between gland 21 and spacer 16, be provided with the second sealing ring 22.
Setting like this, the first sealing ring 20 and the second sealing ring 22 can prevent from dust impurity from entering in bearing impacting bearing life.
This embodiment additionally provides a kind of cast stranding machine, and comprise rotating shaft 14, be arranged at the bracing or strutting arrangement of the creel stand of rotating shaft 14 and supporting revolving shaft 14, bracing or strutting arrangement is bracing or strutting arrangement as above.Setting like this, the cast stranding machine that this embodiment provides, its bearing support assembly has longer useful life, and the derivation of the beneficial effect that the derivation of this beneficial effect and above-mentioned rotating-shaft support devices bring is substantially similar, therefore repeats no more herein.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
