Description
Technical field
The invention belongs to technical field of fluid lubrication, particularly to a kind of bearing-lubricating device.
Background technology
In vehicle high-speed transmission device, rolling bearing, when running up, can produce amount of heat, so that bearing temperature
Rise too high, the heat that rational lubricating system and device can effectively produce with bearing running, reduces bearing temperature rise.Rolling bearing exists
When running up, due to the effect of centrifugal force, the lubricating oil spraying into bearing can be thrown toward bearing outer ring under the influence of centrifugal force
Raceway, so that the lubricants capacity of bearing inner race reduces being even less than, and bearing inner race is in high-speed rotation, and this makes bearing
The temperature of inner ring is far above outer ring, and bearing inner race temperature rise is too high, so that inner ring is produced and weares and teares and deeply worried, thus damaging bearing
Serviceability, and then have influence on the service behaviour of whole transmission system.Therefore, it is necessary to start with from the lubricating arrangement of bearing, change
The lubricating status of kind bearing, reduce bearing temperature rise, the reliability of raising bearing and whole system and durability.
Content of the invention
The purpose of the present invention is：Design one kind makes bearing internal external circle lubricate, radiate all more uniform bearing-lubricating device, with
Realize bearing Homogeneouslly-radiating, the purpose of lubrication,
The technical scheme is that：A kind of high speed roller bearing porous array lubricating arrangement, including：Enter oil jacket and join
Oil jacket；Join oil jacket to be socketed on main shaft, enter oil jacket and fit together with joining oil jacket, and enter oil jacket, join oil jacket and rolling bearing
Fit in side；Enter that oil jacket is static not to be rotated, join oil jacket and rotate with main shaft；
Oil-feed is arranged with the shoe cream room of annular and the oil input channel connecting with shoe cream room；
Join on oil jacket shaft shoulder end face along its circumferentially distributed have two or more axial direction inner ring radiating oil storage hole and two with
Upper nozzle opening group, each nozzle opening group is formed after being arranged in array by the nozzle opening of two or more axial direction；
Join oil jacket shaft shoulder outer circumference surface and to enter gap between oil jacket be outer ring radiating shoe cream room, join oil jacket shaft shoulder end face with
Entering the gap between oil jacket is main oil gallery；
Lubricating oil, after the oil input channel entering oil jacket injects, flows into main oil gallery from shoe cream room, is divided into three tunnels afterwards：One tunnel is from joining
The form that the nozzle opening of oil jacket sentences atomization sprays at the rolling element of rolling bearing；Another road injection inner ring radiating oil storage hole, right
Pulvis Emolliens heat effect is enclosed in rolling bearing；3rd tunnel injection outer ring radiating shoe cream room, encloses lubrication to the outer of rolling bearing
Thermolysis.
Beneficial effect：The lubricating arrangement of the present invention is arranged on rolling bearing side, makes the lubricating oil of entrance lubricating arrangement
Both enabled the effect of oil jet lubrication, and rolling bearing inner ring can have been made to keep certain lubricants capacity, it is to avoid in rolling bearing again
Circle lubricating oil under the effect of high speed centrifugation power is very few, and temperature rise is too high.The shoe cream room of rolling bearing inner ring side may also operate as cold
But the effect of bearing.Lubricating arrangement makes lubricating oil lubricate bearing with vaporific form by the design of oil spit hole, can save
Lubricants capacity, makes lubrication more uniform, and rolling bearing inner ring temperature rise is lower, is favorably improved service life and the work of rolling bearing
Make performance, be quite suitable for the bearing lubrication under high-speed working condition.

Specific embodiment
Referring to accompanying drawing 1,2, a kind of high speed roller bearing porous array lubricating arrangement, including：Enter oil jacket 6 and join oil jacket 8；
Referring to accompanying drawing 1,3, enter oil jacket 6 and be provided with the shoe cream room 10 of annular and the oil input channel 11 connecting with shoe cream room 10；
Join and be evenly distributed with multiple inner rings radiating oil storage holes 9 along its circumference on oil jacket 8 end face and radiate oil storage with inner ring
The one-to-one nozzle opening group in hole 9；As shown in Figure 4：Four nozzle openings 7 are one group；Each nozzle opening group is arranged in an inner ring
Nozzle opening 7 equidistantly linearly (radially) arrangement outside radiating oil storage hole 9, in every group；
Join oil jacket 8 to be coaxially socketed on main shaft 4, enter oil jacket 6 and join oil jacket and 8 fit together, and enter oil jacket 6, join oil jacket 8
Fit with the side of rolling bearing；Enter that oil jacket 6 is static not to be rotated, join oil jacket 8 and rotate with main shaft 4；Join oil jacket 8 outer shroud wall
And entering gap between oil jacket 6 is outer ring radiating shoe cream room 16, join periphery on oil jacket 8 and enter between oil jacket 6 gap based on
Oil duct 15；
Lubricating oil, after the oil input channel 11 entering oil jacket 6 injects, flows into main oil gallery 15 from shoe cream room 10, is divided into three tunnels afterwards：
At one tunnel sprays into the rolling element 2 of rolling bearing from the form that the nozzle opening 7 joining oil jacket 8 sentences atomization；Another road injection inner ring dissipates
