The flexible supporting structure comprises a front ring, a bearing mounting hole is formed in the middle of the front ring, a rolling bearing is arranged in the bearing mounting hole, a tolerance ring is connected between the rolling bearing and the front ring in a clamped manner, the rolling bearing is fixedly connected with a shaft, a protecting sleeve is arranged at the rear end of the rolling bearing and fixedly connected with the front ring, and a starlike spring gasket is arranged between the protecting sleeve and the rolling bearing. Compared with the prior art, the flexible supporting structure has the advantages that the flexible supporting structure is simple, compact and reasonable in structure, low in manufacturing cost, suitable for being used on high-speed centrifugal fans of all specifications, capable of realizing flexible supporting of the front end of an impeller shaft and conducive to overcoming deviation in processing size.
Description
Technical field
The utility model relates to a kind of fan bearing flexible supporting structure, and specifically the sinking support mechanical device of the impact for reducing fan starting, while shutting down on a kind of high-speed centrifugal fan, belongs to mechanical structure technical field.
Background technique
Centrifugal blower is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Centrifugal blower is widely used in ventilation, the dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building; The ventilation of boiler and industrial furnace and air inducing; Cooling and ventilation in the apparatus of air conditioning and domestic electric appliance; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime and Hovercraft and propelling etc.
In prior art, the impeller shaft front end of high-speed centrifugal fan keeps spacing in when operation with front circle, and the effect that is subject to gravity when static is sagging, is starting and during shutdown this front end and front circle generation sliding friction.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of fan bearing flexible supporting structure device is provided, simple in structure, cost is low.
The technological scheme providing according to the utility model, a kind of fan bearing flexible supporting structure, comprises front circle, front circle central authorities offer bearing mounting hole, and rolling bearing is set in bearing mounting hole, between rolling bearing and front circle, are also connected with franchise ring; Rolling bearing is fixedly connected with axle; Rolling bearing rear end is provided with sheath, and sheath is fixedly connected with Qian Quan; Between sheath and rolling bearing, be also provided with star spring washer.
Described sheath is fixedly connected with by several bolts with front circle.Described franchise ring and spring washer are elastic member.
The beneficial effects of the utility model: the utility model is compared with prior art simple in structure, compact, reasonable, and low cost of manufacture, is used on the high-speed centrifugal fan of applicable all specifications; Can realize the sinking support to impeller shaft front end, be conducive to overcome the deviation of processing dimension.

Fig. 1 is the utility model structure sectional view.
Description of reference numerals: 1, Qian Quan; 2, franchise ring; 3, axle; 4, rolling bearing; 5, star spring washer; 6, sheath.
Embodiment
As shown in Figure 1: a kind of fan bearing flexible supporting structure, comprise front circle 1, front circle 1 central authorities offer bearing mounting hole, and rolling bearing 4 is set in bearing mounting hole, between rolling bearing 4 and front circle 1, are also connected with franchise ring 2; Rolling bearing 4 is fixedly connected with axle 3;
Described rolling bearing 4 rear ends are provided with sheath 6, and sheath 6 is fixedly connected with front circle 1; Between sheath 6 and rolling bearing 4, be also provided with star spring washer 5.
Described sheath 6 is fixedly connected with by several bolts with front circle 1.Described franchise ring 2 and spring washer 5 are elastic member.
The inner ring of described rolling bearing 4 is fixedly connected with axle 3, forms the rotating element in structure; Described franchise ring 2 is a kind of elastic parts, and the bearing being installed on rolling bearing 4 and front circle 1 holds between hole; Described star spring washer 5 is a kind of elastic parts, is installed between rolling bearing 4 and sheath 6; Described sheath 6 is fixed and is connected by some screws with front circle 1.
Working procedure of the present utility model: in the moment of fan starting, axle 3 is subject to an axial instantaneous load to the right, this load passes on star spring washer 5 by the outer ring of rolling bearing 4, and star spring washer 5 bears the instantaneous load being transmitted by the outer ring of rolling bearing 4 by the elasticity of self.
In the moment of fan starting, axle 3 starts rotations, and the displacement of the sagging position with elastic compensating axle 3 front ends of franchise ring 2 self when static during to normal operation position, has realized the smooth starting of blower fan.When fan parking, the displacement with elastic compensating axle 3 front ends of franchise ring 2 self, has realized the steady shutdown of blower fan.And use franchise ring can realize reduction front circle 1 upper bearing (metal) is held to the requirement on machining accuracy in hole.
