Description
Technical field
The utility model relates to a kind of shaft assembly, especially relates to a kind of shaft assembly of the HYCO of solution device induced draught fan vibration.
Background technique
At present, it is highly on the steel structure of 30-40 rice that the dual-gripper induced draught fan of a lot of HYCO devices is all arranged on, because steel structure all can be along with temperature and the winding degree of self deform, cause the antero posterior axis bearing concentricity variation that is arranged on steel structure fan to cause that blower fan shakes greatly.Dual-gripper blower fan is all to adopt drive end location anti-drive end to use the axle system of spheric roller bearing substantially now, and this axle is that the surplus at automatic adjusting axle center is little, requires higher for the basis of installing.
A lot of installation data all have higher requirement to the concentricity of assembling diaxon bearing, but HYCO device due to fan outlet temperature is high and also outlet temperature can along with load variation change, steel structure part can be heated and be conducted and change along with the variation of temperature, causes diaxon bearing concentricity to change and causes that blower fan vibrations are large.
Model utility content
The purpose of this utility model is exactly the shaft assembly that a kind of HYCO of solution device induced draught fan vibration is provided in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of shaft assembly that solves the vibration of HYCO device induced draught fan, it is characterized in that, this shaft assembly comprises spheric roller bearing, single row bearing, non-driven-end bearing seat, drive end axle bearing, coupling and mounting base, described spheric roller bearing is arranged in drive end axle bearing, described single row bearing is arranged on non-driven-end bearing seat, described spheric roller bearing is connected by coupling with single row bearing, and described non-driven-end bearing seat, drive end axle bearing are separately fixed in mounting base.
Described non-driven-end bearing seat and drive end axle bearing are arranged on respectively volute of blower two ends.
The model of described spheric roller bearing is 23232CC/W33.
Described single row bearing is CARB bearing.
Described mounting base comprises steel structure upper frame, snubber block and steel structure underframe, described steel structure upper frame is connected with steel structure underframe by snubber block, and described non-driven-end bearing seat and drive end axle bearing are separately fixed on steel structure upper frame.
Compared with prior art, the utlity model has following advantage:
1, antero posterior axis bearing concentricity changes, and blower fan vibrations can not increase.Owing to having used CARB series bearing at the anti-drive end of blower fan, no matter steel structure is along with the variation of temperature changes, and the antero posterior axis bearing concentricity of blower fan changes, and CARB bearing can automatic capturing, and blower fan vibrations can not increase.
2, main shaft expanded by heating can not cause CARB bearing temperature to raise.After the main shaft expanded by heating of blower fan, axial displacement can be adjusted automatically by CARB bearing, can not make blower fan vibrations increase, and can not make bearing temperature raise.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Wherein: 1, single row bearing; 2, spheric roller bearing; 3, non-driven-end bearing seat; 4, drive end axle bearing; 5, coupling; 6, volute of blower; 7, steel structure upper frame; 8, snubber block; 9, steel structure underframe.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.The present embodiment is implemented as prerequisite taking technical solutions of the utility model, provided detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment
As shown in Figure 1, a kind of shaft assembly that solves the vibration of HYCO device induced draught fan, this shaft assembly comprises spheric roller bearing 2, single row bearing 1, non-driven-end bearing seat 3, drive end axle bearing 4, coupling 5 and mounting base, described spheric roller bearing 2 is arranged in drive end axle bearing 4, described single row bearing 1 is arranged on non-driven-end bearing seat 3, described spheric roller bearing 2 is connected by coupling 5 with single row bearing 1, and described non-driven-end bearing seat 3, drive end axle bearing 4 are separately fixed in mounting base.
Described non-driven-end bearing seat 3 and drive end axle bearing 4 are arranged on respectively volute of blower 6 two ends.
Described single row bearing 1 is CARB bearing.
Described mounting base comprises steel structure upper frame 7, snubber block 8 and steel structure underframe 9, described steel structure upper frame 7 is connected with steel structure underframe 9 by snubber block 8, and described non-driven-end bearing seat 3 and drive end axle bearing 4 are separately fixed on steel structure upper frame 7.
The model of spheric roller bearing 2 is 23232CC/W33, CARB bearing is a kind of brand-new radial roller bearing, model is C3232C3, with long and slightly have a symmetrical roller of cambered surface, there is circular raceway outer ring, its cross sectional radius exceeds bearing centre, and inner ring raceway has the shape consistent with outer ring.
The roller of CARB bearing has the Self-aligning ability of spheric roller bearing and the unrestricted axial displacement ability of roller bearing, energy automatic guide position, no matter whether race ring misaligns or has axial displacement, and it can make on the position of load mean effort at whole roller in one.The ability of favourable distributed load makes friction and fricative heat maintain low-level.Running temperature reduces extends the working life of oiling agent and bearing.
CARB has advantage:
Unique inner geometry structure of 1.CARB bearing can be guaranteed the load univesral distribution axial displacement between roller and raceway
