Abstract
The utility model discloses an air cooling device for a fan bearing, which belongs to the technical field of box cooling and comprises a rotary shaft, a cooling wheel, a casing, a base, a bearing, a bearing block and a wind wheel. One end of the rotary shaft extends into the casing; the rotary shaft is provided with the bearing and the cooling wheel; heat in the casing and heat generated by the bearing are transmitted onto the cooling wheel through the rotary shaft; the bearing is arranged in the bearing block; the bearing block is arranged on the base; the wind wheel is matched with the rotary shaft; and wind blown out by the wind wheel passes through the cooling wheel. When the rotary shaft rotates, the wind wheel can rotate along with the rotary shaft, the wind can be generated when the wind wheel rotates, hot air around the cooling wheel is blown away by the wind passing through the position of the cooling wheel, and normal-temperature air is supplemented in, so that a certain temperature difference between the cooling wheel and the air around the same is constantly ensured to facilitate cooling of the cooling wheel.
Description
Technical field
The utility model belongs to the blower fan technical field, a kind of specifically fan bearing air cooling equipment.
Background technique
When blower fan turns round, relative high speed rotating between the outer ring of bearing and the inner ring, make and produce a large amount of heats in the bearing, some blower fan is operated in the high temperature occasion in addition, temperature in the casing is also very high, these temperature also can pass to bearing by rotating shaft, these all can cause the temperature of bearing to raise, and then the working life of shortening bearing, therefore generally all be provided with the device of cooling bearing on the blower fan, traditional bearing cooling unit comprises a heat dissipation plate, heat dissipation plate is arranged on the position between fan casing and bearing in the rotating shaft, and heat dissipation plate generally all is to be made of the good material of thermal conductivity, is furnished with the structure of a lot of increase surface areas on the heat dissipation plate, as groove, hole etc., the heat of bearing and casing all is delivered on the heat dissipation plate by rotating shaft, is dispersed in the air by heat dissipation plate and goes, because the surface area of heat dissipation plate is big and thermal conductivity good, can accelerate heat dissipation rate greatly, prevent the continuous rising of bearing temperature.But because the heat-conducting property of air is not fine, general blower fan is installed in the middle of the pipe network, does not well ventilate, and makes heat dissipation plate ambient air temperature constantly raise, and influences distributing of heat dissipation plate heat.
Summary of the invention
The utility model provides a kind of fan bearing air cooling equipment at deficiency of the prior art, can quicken near the air flows of heat dissipation plate, makes the heat of heat dissipation plate to volatilize rapidly.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: the fan bearing air cooling equipment, comprise rotating shaft, the heat radiation wheel, casing, pedestal, bearing and bearing support, described rotating shaft one end stretches in the described casing, described rotating shaft is provided with bearing and heat radiation wheel, the heat that heat in the described casing and described bearing produce is delivered on the heat radiation wheel by rotating shaft, described bearing is arranged in the bearing support, described bearing support is arranged on the described pedestal, also comprise wind wheel, described wind wheel matches with rotating shaft, and the wind that described wind wheel blows out is through described heat radiation wheel.When rotating shaft was rotated, wind wheel also can be along with rotating shaft be rotated together, and wind wheel can produce wind when rotating, wind dispels the hot air around the heat radiation wheel through heat radiation wheel place, replenishes the into air of normal temperature, make to guarantee to have certain temperature difference between heat radiation wheel and the surrounding atmosphere all the time the heat radiation of convenient heat radiation wheel.
In the technique scheme, described pedestal is provided with the air channel, and described air channel one end opening is positioned at described wind wheel air-out one side, and the other end opening in described air channel is positioned at heat radiation wheel place.The wind that wind wheel blows out blows out from the other end opening after entering air channel one end opening, and the opening of the other end is positioned at heat radiation wheel place, and the convenient air-flow that blows out from the air channel dispels hot air around the heat radiation wheel.
In the technique scheme, described wind wheel is outside equipped with fan housing.The wind that wind wheel blows out may be that all directions have, and is provided with after the fan housing, and the air-flow that makes blower fan blow out is more concentrated.
In the technique scheme, rotating shaft is stretched into a described end end face and is provided with thermal-protective coating on the described casing.
With novel beneficial effect be: when rotating shaft is rotated, wind wheel also can be along with rotating shaft is rotated together, wind wheel can produce wind when rotating, wind is through heat radiation wheel place, hot air around the heat radiation wheel is dispelled, replenish the into air of normal temperature, make to guarantee to have certain temperature difference between heat radiation wheel and the surrounding atmosphere all the time the heat radiation of convenient heat radiation wheel.
Description of drawings
Fig. 1 is a schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Referring to Fig. 1: the fan bearing air cooling equipment, comprise casing 1, rotating shaft 3 and pedestal 2, the end face of the right-hand member of casing 1 is provided with thermal-protective coating 11, described rotating shaft 3 left ends stretch in the casing 1, from left to right be disposed with heat radiation wheel 4, clutch shaft bearing 51, wind wheel 7 and second bearing 52 in the rotating shaft 3, clutch shaft bearing 51 is outside equipped with clutch shaft bearing seat 61, second bearing 52 is outside equipped with second bearing support 62, the clutch shaft bearing seat 61 and second bearing support 62 are fixed on the pedestal 2, wind wheel 7 is outside equipped with fan housing 8, and fan housing 8 also is fixed on the pedestal 2.Pedestal 2 is provided with an air channel 21, and an end opening in air channel 21 is positioned at the below of wind wheel 7, and the wind outlet of wind wheel 7 just, the other end opening in air channel 21 are positioned at the below of heat radiation wheel 4.
During the blower fan running, rotating shaft 3 is rotated, and drives wind wheel 7 and rotates, and wind wheel 7 rotates the air-flow that blows out and blows out through the below of air channel 21 from heat radiation wheel 4, and the hot air around the heat radiation wheel 4 is dispelled, and replenishes the air of normal temperature.Thermal-protective coating 11 is used to prevent to prevent that the high-temperature gas in the casing 1 from heating on a large scale by casing 1 wheel 4 ambient airs that will dispel the heats, and 4 heat dispersion is taken turns in the influence heat radiation.
