Description
Technical field：
The utility model is related to a kind of bearing, and in particular to it is big than pressure high-speed planets axle that one kind is applied to bidirectional rotation
Hold.
Background technology：
In the driving means of main transmission and the aviation of general purpose transmission neutralization ground transport machinery, planetary gear
The supporting overwhelming majority is to adopt rolling bearing, but with the continuous improvement that requires applying working condition of development of science and technology, pair is set
It is standby to propose that high-speed overload requires that at this moment the bearing of planetary gear is belonging to the most heavy supporting of stand under load in Gear Planet Transmission, it is general to adopt
Sliding bearing, reason mainly has：The ability that rolling bearing bears load is more much smaller than the sliding bearing of same volume, rolling bearing
Vibration and noise are relatively large, and particularly after use the phase is especially pronounced, and the life-span of rolling bearing is typically low than sliding bearing.Therefore
This, it is very necessary than pressing high-speed planets bearing that design one kind is applied to bidirectional rotation big.
Utility model content：
The utility model makes up and improves above-mentioned the deficiencies in the prior art part, there is provided a kind of reasonable in design,
Long service life, supporting ＆ stablizing, fuel feeding are stable, compact conformation, and all functional structures are machined on an axle, reduce assembling
Component, applies in the double culvert gear-boxes of twin shaft of bidirectional rotation high-speed overload, and branched power gear props up in the inside and outside shafting of realization
Support, one kind of lubrication are applied to the big ratio pressure high-speed planets bearing of bidirectional rotation, can on a large scale promote and use.
The technical solution adopted in the utility model is：One kind is applied to the big ratio pressure high-speed planets bearing of bidirectional rotation, should
Bearing includes bearing body, bus alloy, latch and temperature element, and Babbitt alloy is divided into two sections and pours and casts from bearing body outer surface,
Latch is installed on the axial end of bearing body and casing assembling, and temperature element is located in the alloy side opening of bearing body, and by tight
Solid glue is fixed.
It is provided with cannelure in the middle of described bearing body, Babbitt alloy is cast respectively the outer surface of cannelure both sides bearing body,
Single fulcrum roller is converted into into double fulcrum rollers.
The alloy face of described Babbitt alloy is provided with N number of oil-feed tank；Be provided with inside described bearing body N number of oil guiding hole and
N number of fuel feed hole, N number of oil guiding hole is respectively communicated with N number of oil-feed tank, and the center fuel feed hole of bearing body is not drilled through so that fuel feed hole is formed
Chamber, it is ensured that input pressure, oil guiding hole makes sliding bearing fuel feeding in the environment that runs up smooth.
Described bearing body is imitative axle shape design, and bearing body axle journal two ends coordinate assembling, bear shaft strength with casing.
Described bearing body is provided with radial direction threaded connection hole, and radial direction threaded connection hole is connected with in-line.
The beneficial effects of the utility model：Reasonable in design, long service life, supporting ＆ stablizing, fuel feeding is stable, and structure is tight
Gather, all functional structures are machined on an axle, reduce assembling assembly, it is easy to promote on a large scale and use.Using two
Oily leaf formula white metal bearing, during bearing runs, due to bearing and planet carrier geo-stationary, outboard gears bidirectional rotary
Turn, bearing external surface both direction stress, in outer surface cast alloys, solves the not fatigue proof shortcoming of Babbitt alloy, greatly
Bearing life is extended greatly；Increase bearing axial length, bearing be divided into into two sections in the middle part of bearing body, will single fulcrum shaft forward
Double fulcrum rollers are turned to, the contact area and stability of strutting system in bearing metal face is effectively increased, bearings ratio to press is reduced；
Process multiple oil guiding holes on bearing, oil guiding hole has the effect of " current stabilization " to lubricating oil, make sliding bearing in the environment that runs up
Fuel feeding is smooth；Bearing body makes imitative axle form, and bearing journal two ends coordinate assembling, bear shaft strength with casing.
