Abstract
The utility model, which belongs in aero-engine transmission casing, lubricates bearing arrangement improved technology.It is specially a kind of to divide equally lubricating oil bearing-lubricating device.It is formed by dividing equally lubricating oil plug, gear shaft, lubricating oil nozzle, plug internal structure is simple, and circumferentially the incomplete through hole of symmetrical two opposite directions, centre are emptied as conical cambered surface.In jet process, by high speed rotation pyramid type face is got rid of point for oil spout, and equalization is entered two holes of left and right by pressurized oil droplet, concentrates on left and right oil pocket along runner, to reach the requirement of uniformly two side bearings of lubrication.
Description
Technical field
The invention belongs to lubricate bearing arrangement improved technology in aero-engine transmission casing.It is specially a kind of to divide equally lubricating oil
Bearing-lubricating device.
Background technique
Existing common lubrication bearing arrangement, as shown in Figure 1.In jet process, oil spout track can be approximately circular rail
Mark, by high-speed rotating U-shaped channel, lubricating oil will be divided into two parts, and a part of lubricating oil is entered by U-shaped aperture along flow path wall
Left side oil pocket lubrication left side bearing, another part is then because being not exclusively overlapped for U-shaped channel and oil spout track forms blocking and suitable
Stream enters the oil pocket on right side, to lubricate the bearing on right side.Although having reached the expected of the multiple positions of lubrication in this way to require,
The lubrication amount that will cause both sides has difference, and causing certain position lubrication needs amounts is more than to be expected, other position lubricating oil amounts are insufficient
Defect.
Summary of the invention
1, autonomous Design divides equally lubricating oil plug, and core technology is to select by the centrifugal force of conical walls, divides equally oil droplet
Two-way.
2, arc inner wall is conducive to throw away the lubricating oil for being adhered to inner wall, promotes lubricating oil flowing, is conducive to discharge.
3, oilhole is respectively opened in two sides on plug, constitutes non-cross two-way oil pathway.
Technical solution
One kind being divided equally lubricating oil bearing-lubricating device and formed by dividing equally lubricating oil plug (5), gear shaft (6), lubricating oil nozzle (7),
Wherein, key part be the design of plug divide equally lubricating oil plug (5) as shown in Fig. 2, by left oil outlet (1), right oil outlet (2),
Oil inlet (3) and get rid of oil pocket (4) composition.Respectively lubricating oil plug (5) installation gear shaft (6) is intracavitary, and left side is solid by gear shaft (6)
Fixed, the place of axially engaging is interference fit, gets rid of the selection direct relation centrifugal force of oil pocket (4) female cone inner wall angle and depth
Size, circumferentially symmetry direction opens up the left oil outlet of diameter 2mm-3mm (1), right oil outlet (2), just lubricating oil can be made smoothly to lead to
Outflow is crossed, respectively magnesium alloy may be selected in lubricating oil plug (5) material.
Technical effect
Plug internal structure is simple, circumferentially the incomplete through hole of symmetrical two opposite directions, centre empty for
Conical cambered surface.In jet process, by high speed rotation pyramid type face is got rid of point for oil spout, and pressurized oil droplet enters equalization
Two holes of left and right, concentrate on left and right oil pocket along runner, to reach the requirement of uniformly two side bearings of lubrication.
Detailed description of the invention
Fig. 1 is common oil jet lubrication bearing arrangement structure chart
Fig. 2 is respectively lubricating oil structure chart
Fig. 3 is improved oil jet lubrication bearing arrangement structure chart
Specific embodiment
Improved oil jet lubrication bearing arrangement structure is by dividing equally lubricating oil plug (5), gear shaft (6), lubricating oil nozzle (7) group
At, wherein key part is that the design of plug divides equally lubricating oil plug (5) as shown in Fig. 2, by left oil outlet (1), right oil outlet
(2), oil inlet (3) and get rid of oil pocket (4) composition.Respectively lubricating oil plug (5) installation gear shaft (6) is intracavitary, and left side is by gear shaft
(6) fixed, the place of axially engaging is to be interference fitted, get rid of the selection direct relation of oil pocket (4) female cone inner wall angle and depth from
The size of mental and physical efforts, circumferentially symmetry direction opens up the left oil outlet of diameter 2mm-3mm (1), right oil outlet (2), just can make lubricating oil
Outflow is passed through, respectively magnesium alloy may be selected in lubricating oil plug (5) material.
Working principle is that lubricating oil is ejected on the cone wall for getting rid of oil pocket (4) leading portion by oil inlet (3), and gear shaft (6) drives
Respectively lubricating oil plug (5) rotates, and is acted on by centrifugal rotation, and lubricating oil, which is distributed to, to be got rid of on oil pocket (4) circumferential inner wall, and generates centainly
Pressure is in the lubricating oil compression power effect of left oil outlet (1), right oil outlet (2), lubricating oil discharge is got rid of oil pocket (4), realizes oil spout
The lubricating oil of mouth injection is divided into two-way, respectively the bearing of oilgear axis (6) two sides.Due to lubricating oil get rid of oil pocket (4) by rotation from
The heart effect, be distributed to the probability of two oil outlets be it is equal, all structures can realize the purpose of respectively lubricating oil.
Claims (2)
1. one kind divides equally lubricating oil bearing-lubricating device, formed by dividing equally lubricating oil plug (5), gear shaft (6), lubricating oil nozzle (7),
It is characterized in that respectively lubricating oil plug (5) by left oil outlet (1), right oil outlet (2), oil inlet (3) and gets rid of oil pocket (4) and constitutes；
Respectively lubricating oil plug (5) installation gear shaft (6) is intracavitary, and left side is fixed by gear shaft (6), and the place of axially engaging is interference fit, root
Oil pocket (4) female cone inner wall angle and depth are got rid of according to the size setting of centrifugal force, circumferentially symmetry direction opens up diameter 2mm-3mm
Left oil outlet (1), right oil outlet (2), just can make lubricating oil pass through outflow.
2. a kind of respectively lubricating oil bearing-lubricating device according to claim 1, it is characterised in that: described to divide equally lubricating oil plug
(5) material is magnesium alloy.
