Abstract
The invention provides an anti-oil leakage device for a bearing pedestal of an air blower. The anti-oil leakage device for the bearing pedestal of the air blower provided by the invention is realized as follows: selecting a galvanized thin iron sheet with the thickness of 1.5 mm to 2 mm and the width of 26 mm to 30 mm for enclosing a lap along the shaft diameter of the air blower and then lengthening 25 mm, cutting out a section for making a blade looping thigh; cutting off the iron sheet at the interval of 8 mm in the direction of the width of the iron sheet by scissors, wherein the cutting depth is the half of the width of the iron sheet, turning up the cutting edge for 90 degrees, turning up each blade for 30 degrees vertically along an air blower rotating shaft, and rotating for an angle, so that a small-sized fan is formed. When the blades are placed on one side close to an end cover of the bearing pedestal, the blade looping thighs are tightly looped on the shaft by a short screw, and the end cover is mounted finally. When the air blower rotates, the blades mounted on the shaft blow the oil inwards with the help of the rotating force, so that the oil leakage is prevented effectively. The anti-oil leakage device for the bearing pedestal of the air blower provided by the invention has the benefits that the structure is simple, the installation is convenient, the service life is long, and the sealing function is good.
Description
Technical field
The present invention relates to the device that prevents the bearing support leakage of oil on a kind of boiler induced draft equipment, it is mounted in the induced draft bearing support, can carry out effective sealing to lubricant oil in the bearing support, and is simple in structure, install very conveniently, can not affect the normal operation of induced draught fan.
Background technique
The boiler of commonly using at present draws, the blower shaft bearing prevents that the method for leakage of oil from being to seal by the filler in the forward and backward end cap of bearing support; leakage of oil just just passable with tightening on the screw on the Gland; but in actual use; since the blower fan Gland from the Blower Housing spacing very close to; very difficult to adding filler, usually can not run into owing to correctly not added filler and cause a large amount of leakage of oils.
Summary of the invention
A kind of Leakageproof device for bearing seat of fan of the present invention is achieved like this: select thickness at 1.5mm～2mm, width lengthens 25mm at the galvanized sheet of 26mm～30mm scope again after the blower fan diameter of axle makes a circle, cut one section, does a blade and embraces thigh.Along the iron sheet width direction, every interval 8mm cuts off with scissors again, cuts off the degree of depth and be half of iron sheet width, again the limit that is cut is dug 90 °, and more every a slice is vertically become 30 ° along fan shaft, rotates an angle, becomes a small-sized fans.Blade is placed on the side by bearing cover, embraces thigh with short key screw blade again and embraces tightly on axle, loads onto at last end cap.When blower fan rotates, be contained in blade on the axle along with sense of rotation is blown oil vertically inward, so just can very effectively stop leakage of oil.
Beneficial effect of the present invention is simple in structure, and is easy for installation, and long service life can seal preferably.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of Leakageproof device for bearing seat of fan mounting structure schematic diagram.
(1) among the figure, front cover, (2), bearing block base, (3), rear end cover, (4), embrace a strand screw, (5), front vane are embraced thigh, (6), axle, (7), fore bearing, (8), rear blade is embraced thigh, (9), draught fan impeller, (10), rear bearing.
Embodiment
In order to improve sealing effect, first the forward and backward end cap on the bearing support is removed, be placed on the lathe end cap internal surface car is flat, then select thickness at 1.5mm～2mm, width lengthens 25mm at the galvanized sheet of 20mm～30mm scope again after the blower fan diameter of axle makes a circle, cut one section, do a blade and embrace thigh.Along the iron sheet width direction, every interval 8mm cuts off with scissors again, cuts off the degree of depth and be half of iron sheet width, namely about 10mm～15mm, again the limit that is cut is dug 90 °, and more every a slice is vertically become 30 ° along fan shaft, rotate an angle, become a small-sized fans.Blade is placed on the side by bearing cover, embraces thigh with short key screw blade again and is fixed in advance on the fan shaft, and trying in advance covers bearing cover, its objective is to allow blade can lean against end cap face place, more near better, open at last end cap, tightly blade is embraced again thigh and fixed, load onto end cap.
What the present invention and conventional shaft sealing were different is, it is that the blade that is mounted on the axle is embraced thigh, when blower fan rotates, is contained in blade on the axle by rotating force, and oil is blown vertically inward, so just can very effectively stop leakage of oil.
Claims (1)
1. a bearing fan prevents the device of leakage of oil, it is characterized in that: select thickness at 1.5mm～2mm, width lengthens 25mm at the galvanized sheet of 26mm～30mm scope again after the blower fan diameter of axle makes a circle, cut one section, do a blade and embrace thigh, again along the iron sheet width direction, every interval 8mm cuts off with scissors, cut off the degree of depth and be half of iron sheet width, again the limit that is cut is dug 90 °, and more every a slice is vertically become 30 ° along fan shaft, rotate an angle, become a small-sized fans, blade is placed on the side by bearing cover, embraces thigh with short key screw blade again and embraces on axle tightly.
