Abstract
The utility model discloses a centrifugal blower, which comprises an oil tank, an oil slinger, a bearing chock, and a partition board dividing the oil tank into an inner oil chamber and an outer oil chamber, wherein an oil hole allowing the cool oil at the upper middle part of the outer oil chamber to pass into the inner oil chamber is arranged on the partition board, the oil slinger is arranged inside the inner oil chamber, and a hot oil returning channel capable of conveying the hot oil at a bearing to the bottom part of the outer oil chamber is arranged on the bearing chock. Besides, heat radiation ribs are arranged at the outer part of the oil tank. The utility model has the advantages of good lubricating and cooling effects, water source conservation, simple structure and manufacturing cost reduction.
Description
Technical field
The utility model relates to a kind of centrifugal blower, particularly relates to the lubricating and cooling system of centrifugal blower.
Background technique
Its fuel tank shell of centrifugal blower (see figure 3) that is lubricated with the splash lubrication mode at present is an interlayer, be connected with cooling water in the interlayer and be used for cooling off the lubricant oil of fuel tank, has only a grease chamber in the fuel tank, there is a disc to be fixed in the rotating shaft in this grease chamber, rotation by rotating shaft drives disc and the oil in the grease chamber is thrown on the bearing bearing is lubricated, still directly get back to this grease chamber from the deep fat that bearing flows down, continuation is thrown on the bearing by disc and is lubricated, so make the cooling effect of lubricant oil rely on the interior cooling water of fuel tank shell fully repeatedly, and the fuel tank structure complexity, the manufacture cost height.
The model utility content
The purpose of this utility model is to provide a kind of and has good lubricated cooling effect, and low cost of manufacture, and working service is centrifugal blower easily.
This centrifugal blower that the utility model provides comprises bearing support, fuel tank, disc, also comprise a dividing plate that is used for described fuel tank is divided into interior grease chamber and outer grease chamber, the oil through that the cold oil of middle and upper part, outer grease chamber is fed interior grease chamber is arranged on this dividing plate, described disc has one bearing place deep fat sent into the deep fat back oil road of bottom, outer grease chamber in interior grease chamber on the described bearing support.
Described fuel tank outside is provided with radiation rib.
Because the utility model has been divided into inside and outside two grease chambeies with fuel tank, and the deep fat behind the lubricated cooling bearing drains into bottom, outer grease chamber by the deep fat back oil road, large size radiation rib heat radiation through the fuel tank outside is fully cooled off, the circulation of cooling back enters interior grease chamber, so oil is always low temperature oil in the interior grease chamber, guarantee the good lubrication of bearing and gear.And in the grease chamber, only in interior grease chamber, stir in disc of the present utility model is installed in, can not make outer grease chamber produce oily foam, be in best lubricated constant oil level admittedly can guarantee bearing.Therefore the lubricated good cooling results of the utility model is simple in structure, the manufacture cost reduction.And in the grease chamber, only in interior grease chamber, stir in disc of the present utility model is installed in, can not make outer grease chamber produce oily foam, be in best lubricated constant oil level Gu can be able to guarantee bearing.Therefore the lubricated good cooling results of the utility model is simple in structure, the manufacture cost reduction.During work, oil in the interior grease chamber splashes by disc on the bearing, it is carried out cooling and lubricating, bottom, grease chamber outside the deep fat backflow road of deep fat from bearing support drains into, large size radiation rib through the fuel tank outside is fully cooled off, make the lubricant oil that is recycled in the interior grease chamber can keep low relatively temperature, continue the subzero oil in the interior grease chamber is got rid of to bearing, make bearing fully be cooled off, lubricate so repeatedly by disc.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A portion enlarged view of Fig. 1.
Fig. 3 is that the B of Fig. 2 is to view.
Fig. 4 is the prior art constructions schematic representation.
Embodiment
Referring to Fig. 1 and Fig. 2, therefrom the utlity model has fuel tank 2 as can be seen, disc 1, bearing support 3, bearing 6, impeller shaft 7, also have a dividing plate 4 to be fixed in the fuel tank 2, fuel tank 2 is divided into interior grease chamber 21 and outer grease chamber 22, there is oil through 41 that the cold oil on 22 tops, outer grease chamber is fed in the interior grease chamber 21 on the dividing plate 4, have a deep fat back oil road 5 on the bearing support 3, the bottom of grease chamber 22 outside this deep fat back oil road leads in bearing support 3, the deep fat that flows down behind the lubricating bearings is delivered to the bottom cooling of outer grease chamber 22, and the low temperature oil of middle and upper part, outer grease chamber enters the interior grease chamber 21 from oil through 41, disc 1 is in this in grease chamber, it is along with the rotation of impeller shaft 7 constantly is thrown to the oil of interior grease chamber on the bearing 6, and this bearing is lubricated and cools off.The outside of fuel tank 2 is provided with many radiating fin 8, and fuel tank is carried out air cooling.Make this machine play fine lubricated cooling action and can save constituent thus, saved the water source and made the fuel tank manufacturing simpler bearing.
Claims (2)
1, a kind of centrifugal blower, comprise bearing support (3), fuel tank (2), disc (1), it is characterized in that also comprising a dividing plate (4) that is used for described fuel tank (2) is divided into interior grease chamber (21) and outer grease chamber (22), the oil through (41) that the cold oil of middle and upper part, outer grease chamber (22) is fed interior grease chamber (21) is arranged on this dividing plate (4), described disc (1) is positioned at bearing (6) and locates the bottom that a deep fat back oil road (5) feeds outer grease chamber (22) in interior grease chamber (21) on the described bearing support (3).
2, centrifugal blower according to claim 1 is characterized in that the outside of described fuel tank (2) is provided with radiating fin (8).
