Abstract
The invention relates to a flexible supporting structure for a fan bearing and belongs to the technical field of mechanical structures. The flexible supporting structure for the fan bearing comprises a front ring, a bearing installation hole is formed in the center of the front ring, a rolling bearing is arranged in the bearing installation hole and a tolerance ring is clamped between the rolling bearing and the front ring; the rolling bearing is fixedly connected with a shaft; a sheath is arranged at the rear end of the rolling bearing and is fixedly connected with the front ring; a star-shaped elastic washer is arranged between the sheath and the rolling bearing. Compared with the prior art, the flexible supporting structure for the fan bearing has the advantages that the structure is simple, compact and reasonable, the manufacturing cost is low and the flexible supporting structure is suitable for use on high-speed centrifugal fans in all specifications; the flexible supporting of the front end of an impeller shaft can be realized and the overcoming of the deviation of processing dimension is facilitated.
Description
Technical field
The present invention relates to a kind of fan bearing flexible supporting structure, specifically the sinking support mechanical device of 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; Inflation and the propelling etc. of wind-tunnel wind regime and Hovercraft.
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, starting and when shutdown, and this front end and front circle generation sliding friction.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, thereby a kind of fan bearing flexible supporting structure device is provided, simple in structure, cost is low.
According to technological scheme provided by the invention, a kind of fan bearing flexible supporting structure, comprises front circle, and 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.
Beneficial effect of the present invention: the present invention 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.
Brief description of the drawings
Fig. 1 is structure sectional view of the present invention.
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 invention: 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 rotation, 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.In the time of fan parking, with the displacement of elastic compensating axle 3 front ends of franchise ring 2 self, realize 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.
