Abstract
The invention relates to a device for reducing bearing temperature, comprising a bearing body, wherein a group of oil return holes is formed in the side lower part of the bearing body, and the axial lead of the oil return holes and the center line of a bearing form an angle of 45 degrees. According to the invention, by forming the oil return holes in the bearing, the oil return quantity is increased so as to reduce the temperature of the bearing, on the premise that the integral structure, the strength and the working environment of the bearing are not affected, the problem of overhigh radial bearing temperature can be effectively controlled, the phenomenon of overhigh bearing temperature caused by insufficient oil return is avoided, the phenomenon of interlocking jump caused by overhigh bearing temperature is further avoided, and stable production is ensured.
Description
Technical field
The present invention relates to a kind of device that reduces bearing temperature.
Background technique
4TYD112 type air compressor is the empty dispenser sleeve unit of steel-making project, the compression of single shaft level Four, and its specified air displacement is 53000m
3/ h, rotating speed 7353r/min.There is an oil supply hole between every two pieces watts of the prior art middle (center) bearing, circumferentially be evenly arranged 5 fuel feeding apertures, oil return is fixedly to force under pressure to discharge in the gap between baffle ring and axle by bearing tile, and in the process of discharging in oil return, bearing temperature raises fast.This unit operation, after a period of time, checks that significantly rise phenomenon has appearred in its radial bearing temperature of discovery, and 105 ℃ of left and right, and the interlocking of unit temperature point jumping car value is 120 ℃, thereby has affected the stable operation of air separation facility, has reduced the stability of producing.
Summary of the invention
The object of the invention is to: for the problem of above-mentioned prior art existence, propose the device of reduction bearing temperature a kind of simple in structure, reasonable in design.
In order to reach above purpose, the device of reduction bearing temperature of the present invention, comprise bearing body, and its improvements are, at the side-lower of described body, has one group of spill port, and shaft axis and the bearing axis of described spill port are 45° angle.Like this, spill port is distributed on bearing obliquely, directly is not sprayed onto on axle when guaranteeing by the spill port oil return.
It is that described bearing is the full immersed type tilting-pad bearing that the present invention further improves.
It is that described spill port is distributed on the tile fragment fixing frame of bearing that the present invention further improves.Described spill port is distributed in the tile fragment gap on the tile fragment fixing frame.
The present invention further improves, and the number of described spill port is 2, and the diameter of described spill port is 6.5mm, and its oil return area is 47% of oil-feed area.
The invention has the advantages that: the present invention reduces the device of bearing temperature, increase recirculating oil quantity by open spill port on bearing, to reduce the temperature of bearing, under the prerequisite that does not affect bearing integral structure, intensity and working environment, can effectively control the problem of radial bearing excess Temperature, avoided because of the not enough Bearing Temperature caused of oil return, and then the interlocking of having avoided Bearing Temperature to cause jumping car phenomenon, production stable operation guaranteed.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
The A-A that Fig. 2 is Fig. 1 is to sectional view.
Embodiment
Embodiment one
The device of the reduction bearing temperature of the present embodiment, its structure as depicted in figs. 1 and 2, comprises bearing body, at the side-lower of body, has the spill port 1 that 2 diameters are Ф 6.5mm, its oil return area is 47% of oil-feed area, and shaft axis and the bearing axis of spill port 1 are 45° angle.Wherein, bearing is the full immersed type tilting-pad bearing, and spill port 1 is distributed on the tile fragment fixing frame of bearing, is specially spill port 1 and is distributed in two tile fragment 2 gaps on the tile fragment fixing frame.
During use, first with reference in kind, the relative dimensions parameters such as spill port, bearing bore diameter, the diameter of axle are measured one by one, the dimensional parameters that utilization is measured, calculate oil-feed sectional area and the oil return sectional area of this bearing, by relatively judge bearing temperature higher whether be that the oil return deficiency causes, then according to judged result, the side analyzed in the existing oil return of this radial bearing increases spill port.Do not affecting bearing integral structure and intensity, do not change under the prerequisite of working environment of bearing simultaneously, make the oil return sectional area reach the certain percentage setting of oil-feed sectional area, first according to the existing total oil-feed sectional area of bearing of the sizecalculation of oil inlet hole, according to all spill port sectional areas of bearing, be the desired percentage of oil inlet hole sectional area, calculate the scope of the sectional area of spill port, then by calculating, open several Kongzuis close with the oil inlet hole size suitable under the prerequisite that does not affect bearing integral structure and intensity, meet the designing requirement that bearing soaks entirely simultaneously.Regional as illustrated in fig. 1 and 2, according to the aperture calculated.
After the perforate aperture calculated, recirculating oil quantity increases, and has also accelerated the circulation of lubricant oil simultaneously, and lubricant oil has been taken away a part of heat of bearing in lubricated process, thereby reaches the purpose that reduces bearing temperature.
In addition to the implementation, the present invention also can have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, drop on the protection domain of requirement of the present invention.
