Description
Technical field
The utility model relates to a kind of bearing combination on permanent-magnet variable-speed device cantilever rotor.
Background technology
At present, permanent-magnet variable-speed device on market, it combines for the bearing of rotor, vibrational power flow Shortcomings, power shaft and output shaft cannot independently assemble, more loaded down with trivial details when install and adjust, accidentally causing cannot be concentric between power shaft and output shaft, and inner and outer rotors cannot centering, easily unstable in running like this, form certain shake, the useful life that impact is overall and serviceability, have much room for improvement.
Utility model content
The purpose of this utility model is to provide a kind of bearing combination on permanent-magnet variable-speed device cantilever rotor, power shaft can be realized, output shaft carries out independent assembling, be suitable for and install and adjustment, guarantee that power shaft, output shaft are concentric, and then realize inside and outside magnet rotor centering, stable.
For achieving the above object, the technical solution of the utility model is:
Bearing combination on permanent-magnet variable-speed device cantilever rotor, it is characterized in that: comprise rotating shaft, described rotating shaft is furnished with left bearing and right bearing, common bear box is provided with in the outside of described left bearing and described right bearing, at described bear box and described left bearing, bearing a set of cups is provided with between described right bearing, bearing cap is provided with in the side of described left bearing, described bearing a set of cups comprises body, the upper port limit of described body forms evagination horizontal annular and prolongs limit, lower port limit forms the short annular edge of convex horizontal, described short annular edge is buckled in described right bearing place, described annular prolongs limit, described bearing cap, described bear box is bolted locking.
Compared with prior art, the beneficial effects of the utility model:
The utility model realizes installation to left bearing and right bearing and adjustment by bearing a set of cups, because right bearing, left bearing are close on the inwall of bearing a set of cups simultaneously, so easily guarantee left bearing and right bearing concentric, also be applicable to installing and adjustment simultaneously, guarantee inside and outside magnet rotor centering, because left bearing and right bearing are in concentric position, so just realize the stable of speed changer.
In addition, the utility model is when adjustment, and can carry out adjustment by bolt and install, operation is very easy flexibly, improves and install and regulate efficiency.
As from the foregoing, the utility model can realize power shaft, output shaft carries out independent assembling, is suitable for and installs and adjustment, guarantees that power shaft, output shaft are concentric, and then realizes inside and outside magnet rotor centering, stable.
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to accompanying drawing 1, present embodiment discloses a kind of bearing combination on permanent-magnet variable-speed device cantilever rotor, it is characterized in that: comprise rotating shaft 1, described rotating shaft 1 is furnished with left bearing 2 and right bearing 3, common bear box 4 is provided with in the outside of described left bearing 2 and described right bearing 3, at described bear box 4 and described left bearing 2, bearing a set of cups 5 is provided with between described right bearing 3, bearing cap 6 is provided with in the side of described left bearing 2, described bearing a set of cups 5 comprises body 7, the upper port limit of described body 7 forms evagination horizontal annular and prolongs limit 8, lower port limit forms the short annular edge 9 of convex horizontal, described short annular edge 9 is buckled in described right bearing 3 place, described annular prolongs limit 8, described bearing cap 6, described bear box 4 connects locking by bolt 10.
The utility model realizes installation to left bearing 2 and right bearing 3 and adjustment by bearing a set of cups 5, because right bearing 3, left bearing 2 are close on the inwall of bearing a set of cups 5 simultaneously, so easily guarantee left bearing 2 and right bearing 3 concentric, also be applicable to installing and adjustment simultaneously, guarantee inside and outside magnet rotor centering, because left bearing 2 and right bearing 3 are in concentric position, so just realize the stable of speed changer.
The foregoing is only an embodiment of the present utility model, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection range of this case.
