Description
Technical field
The utility model relates to a kind of Fan Bearing Box, relates in particular to a kind of water-cooled oil immersed type Fan Bearing Box.
Background technique
In the prior art, water-cooled oil immersed type Fan Bearing Box all adopts the water channel casting, and the water channel position is arranged in the casing that is surrounded on the bearing outer ring position.The heating of equipment operation process middle (center) bearing case mainly contains two aspects and causes: a part is outer heat, namely be used for baking oven, drying room, boiler and draw blower fan under the high temperature environment such as phoenix because extraneous working condition causes heating, a part is interior heat, namely for the blower fan that runs up under the normal temperature, friction generates heat causes the bearing housing heating because axle runs up in the bearing housing.Be to solve heat radiation, be used for having the blower fan under the outer working condition to be furnished with water-cooled oil immersed type bearing housing, next well matchedly has a common oil immersed type Fan Bearing Box there not being outer thermal technology to make situation.There is following defective in actual applications in water-cooled oil immersed type bearing housing.The first, existing water-cooled oil immersed type Fan Bearing Box is done under the situation being in outer thermal technology, causes easily bearing housing to be scrapped.Be in the centrifugal blower in the outer thermal condition, impeller is always in air draft or draw phoenix hot gas, so the reel of impeller and the impeller of ining succession at first heats up, then reel is transmitted to heat on the main shaft of bearing housing, main shaft heats up and heat is conducted to bearing, bearing heats up and heat is conducted to lubricant oil and makes it to heat up, after temperature is raised to certain limit, because the expansion of bearing ball directly reduces the gap of ball and bullet grain, add the too high viscosity that loses of lubricating oil temperature and do not have lubricated effect, finally cause bearing ball and play groove killing, if this moment, drive motor also can cause bearing inner race and main shaft in running, bearing outer ring and casing, and hard friction rotates between bearing ball and Internal and external cycle bullet groove, finally causes main shaft, bearing and casing are scrapped.Existing water-cooled oil is invaded the formula bearing housing, although can make it not heat up in outside casing position, place, cooling bearing axle box bearing position by cooling water, the tank surface feel is not scalded, the bearing outer ring that contacts with casing also has certain cooling effect, but does not play real cooling effect for whole bearing; In contrast, this cooling means has stoped the gap of casing and bearing inside, makes that bearing is easier kills, and more can not effectively stop the intensification of lubricant oil.The second, existing water-cooled oil immersed type Fan Bearing Box water channel is casting; sand, pore, crackle, the water channel chamber casting defect such as subside often can appear in the water channel adding; and can not see the quality condition of water channel inside by external observation; generally also be difficult to directly try out with hydraulic pressure, often appearance quality problems such as seep water, leak just after use after a while.
In sum, the defects that exists in order to overcome prior art is necessary to make improvements.
The model utility content
The utility model provides a kind of water-cooled oil immersed type Fan Bearing Box, and the whole front side cap of effective cooling has effectively stoped from the heating of impeller thermal source to whole bearing housing, effectively reduces the temperature of lubricant oil, has improved lubricity.
The utility model is to solve the problems of the technologies described above the technological scheme that adopts to provide a kind of water-cooled oil immersed type Fan Bearing Box, comprises casing, and described box house is installed main shaft, and described main shaft one end is impeller end, and the other end is pulley end; Upside one end of described casing arranges water intake, and the other end sets out the mouth of a river; Described casing one end arranges front side cap, and the other end arranges rear side cover, and described tank floor is offered the water port, and wherein, described front side cap inside arranges the front side water annulus, and described rear side cover inside arranges the rear side water annulus.
Above-mentioned water-cooled oil immersed type Fan Bearing Box, wherein, cross section, described water port is semicircle.
Above-mentioned water-cooled oil immersed type Fan Bearing Box wherein, is bolted to connection between described front side cap, rear side cover and the casing.
Above-mentioned water-cooled oil immersed type Fan Bearing Box, wherein, blackout sealing gasket between described front side cap, rear side cover and the casing, described main shaft and casing joint arrange seal ring.
Above-mentioned water-cooled oil immersed type Fan Bearing Box, wherein, described casing upside is offered tank filler sleeve, and described tank filler sleeve is equipped with the tank filler sleeve bolt, and described casing downside is offered fuel outlet, and the fuel outlet upside is provided with oil ga(u)ge.
The utility model contrast prior art has following beneficial effect: the water-cooled oil immersed type Fan Bearing Box that the utility model provides, by front side water annulus entry, at first cool off whole front side cap, front side cap will effectively stop from the heating of impeller end thermal source to whole bearing housing.Cooling water is by the water port of bottom half, the cross section of water port is semicircle, so the water port profile has very large outer surface to contact with the interior lubricant oil of casing, so the effect of cutting oil is fine, as long as regulate the flow velocity of cooling water, lubricant oil is in the lower operating temperature always, can keeps for a long time the oil product of lubricant oil.The Lower Half of bearing is immersed in the lubricant oil all the time, several circles of bearing revolution, and ball will pass through lubricant oil once, thereby can well reduce the temperature of bearing and the lubricity of raising bearing.In addition, the water port is the cooling water water channel, is again the longeron of connect box front and back bearings position, plays before and after the casing and the effect of bottom surface stiffening rib, and keeps the casing outer bottom smooth attractive in appearance.In addition, product front side water annulus, the rear side water annulus that the utility model provides all adopts machining to form, and channel structure simply is easy to processing, though can increase the machining expense, can effectively guarantee the quality of water channel.The pore that this product can avoid the casting water channel to produce, burning into sand, crackle, the casting defects such as the water channel chamber subsides, significantly reduced the technical difficulty of cast bearing case blank, save the required water channel moulding loam core of cast bearing case blank, can also reduce the sand removal difficulty of blank, thus required technical requirements and cost of labor when reducing bearing housing casting blank.
