Abstract
The utility model discloses a heat radiating device for fan bearings, comprising a sleeve barrel, a heat radiating impeller and an impeller cover. The sleeve barrel is sheathed and fixed on a main shaft between the bearings, the heat radiating impeller is positioned at the inner side of the bearings and is fixed in one with the sleeve barrel, and the impeller cover is arranged at the periphery of the impeller. When the utility model is working, air enters the impeller cover from the bottom of the impeller cover, the impeller rotates at a high speed following the fan shaft and sends airflow to the bearings at the both ends, then the heat of the bearings is carried away in time, and that allows the bearings to stay in good working condition all the time. The device adopts air cooling to cool down and is simple in structure, and lengthens the service life of the bearings.
Description
The utility model belongs to sink, is specifically related to a kind of sink that is used for the fan bearing cooling.
High pressure centrifugal ventilator main shaft two ends are supported by bearing; because main shaft continuous high speed running; make bearing produce a large amount of frictional heats, cause bearing temperature to raise, surpass the operating temperature range that allows; thereby cause the fan bearing wearing and tearing to be accelerated; when serious bearing will be scrapped, blower fan is forced to out-of-blast, shuts down maintenance; the wind devices ordinary production is used in influence, causes economic loss.
The purpose of this utility model provides a kind of bearing sink that adopts forced air cooling, can effectively reduce the bearing working temperature.
Technical solution of the present utility model is: this bearing sink comprises sleeve, heat-dissipating impeller and impeller chimney.Sleeve set also is fixed on the main shaft between bearing, and it is inboard and be fixed as one with sleeve that heat-dissipating impeller is positioned at bearing, and impeller chimney is arranged on the impeller periphery.
For concentrating wind-force, the end face of heat-dissipating impeller is designed to arc, is evenly equipped with blade on the end face.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the scheme of installation of sink.
Wherein: 1, blade 2, impeller 3, impeller 4, blade 5, sleeve 6, Fan casing 7, bearing support 8, bearing 9, impeller chimney 10, set screw 11, bearing support 12, bearing 13, blower fan axle 14, belt pulley 15, support
As shown in Figure 1, the blade of the utility model bearing sink 1,4 is uniform and be welded on the impeller 2,3, and impeller 2,3 is installed in opposite directions and welded together with sleeve 5.
With reference to Fig. 2, diaxon bearing 7,11 is fixedly mounted on the support 15, and fan casing 6 is positioned at support 15 1 sides.The sleeve 5 of sink and is fixed together by set screw 10 and blower fan axle 13 between two bearings 8,12.Impeller chimney 9 spiral-locks are on sink, and its both sides and support 15 are fixing.
During work, air is entered in the cover by the impeller chimney below, and impeller is the arbor high speed rotating with the wind, and air-flow is sent to bearings at both ends, in time the bearing heat is taken away, and makes bearing be in good working order all the time.
The utility model need not change the structure of original equipment, only needs sink is contained between the two bearings of blower fan axle, carries out wind cooling temperature lowering, and it is simple in structure, respond well.Adopt this device to compare, can prolong several 10 times of bearing working life with original blower fan, guaranteed the normal operation of blower fan, avoided unnecessary economic loss.
In addition, blower fan axle head of the present utility model also is equipped with belt pulley 14, and the user is selection and motor or the supporting use of diesel engine respectively, both economizes on the use of funds, and saves trouble again conveniently.
Claims (2)
1, a kind of bearing sink is characterized in that this device comprises sleeve, heat-dissipating impeller and impeller chimney, and sleeve set also is fixed on the main shaft between bearing, and it is inboard and be fixed as one with sleeve that heat-dissipating impeller is positioned at bearing, and impeller chimney is arranged on the impeller periphery.
2, bearing sink according to claim 1 is characterized in that above-mentioned heat-dissipating impeller end face is an arc, and is evenly equipped with blade on the end face.
