Abstract
The invention discloses an oil way and sealing structure for a bearing block. The oil way and sealing structure for the bearing block comprises a case shell, the bearing block, a bearing, a first-level-sealing sealing ring and a second-level-sealing sealing ring. A lubricating oil way for lubricating the bearing and passing the bearing to a next oil way is designed on the case shell. An oil way and an oil supply hole which correspond to the lubricating oil way on the case shell are further designed in the bearing block. When the bearing block is installed in the case shell, a convergent annular boss is designed on the inner surface of a case, a convergent annular boss is also designed on the outer surface of the bearing block, and an annular oil way is formed between the annular bosses. In addition, an annular first-level sealing groove and an annular second-level sealing groove are designed in the upper end and the lower end of the upper oil way of the bearing block correspondingly, and when the first-level sealing groove and the second-level sealing groove are installed in the case shell after the first-level sealing groove in the bearing block is sleeved with the first-level-sealing ring and the second-level sealing groove in the bearing block is sleeved with the second-level sealing ring, sealing can be conducted on the annular oil way. By means of the structure, the beneficial effects that the technology is more convenient to implement, it can be ensured that the sealing rings are stressed evenly during assembly, lancing is not liable to happen, and the sealing effect is good are achieved.
Description
Technical field
The present invention relates to the oil circuit of a kind of bearing block, refer more particularly to oil circuit and the seal structure of bearing block.
Background technology
Being arranged in the structure of wheel chamber casing in current axis bearing, lubricating oil is entered by the annular groove oil circuit on casing
Entering bearing block to bearing feed lubrication, obturaging oil circuit two ends between bearing block and wheel chamber casing is employing two
Level O type rubber seal seals, in this structure, and the outer surface of bearing block and the interior table of wheel chamber casing
Face is all designed to straight line section, and installing general due to bearing block and casing is the most all to use interference fits.
In installation process, primary seal circle can be by 2 extruding, by easily making because of unbalance stress during second time extruding
Become sealing ring impaired, thus lubrication leakage can be caused, affect dependability.Particularly require higher
Using on Aeronautics and Astronautics equipment, propose higher requirement to installing, its installation cost can increase considerably.
Summary of the invention
The invention aims to solve above-mentioned weak point, design a kind of new bearing block oil circuit and envelope
Tight structure.
For achieving the above object, the present invention is by the following technical solutions:
The oil circuit of a kind of bearing block and seal structure include that wheel chamber casing, bearing block, bearing, one-level are obturaged close
Seal, two grades of sealing rings of obturaging.Wherein it is designed with on wheel chamber casing for lubricating this bearing and being delivered to the next one
The lubricant passage way of oil circuit, devises the annular of a convergence on the inner surface that wheel chamber casing installs bearing saddle bore
Boss.The oil circuit corresponding with the lubricant passage way on wheel chamber casing and oil supplying hole it is designed with, at axle on bearing block
Outer surface in bearing also devises the annulus boss of a convergence.In bearing block is arranged on wheel chamber casing,
By annular boss on casing inner surface and formed between the annulus boss on bearing block outer surface annular oil circuit.And
On bearing block the two ends up and down of oil circuit have also been devised annular one-level obturage groove and annular two grades of grooves of obturaging.Work as axle
One-level in bearing is obturaged and is set with one-level on groove and two grades of grooves of obturaging and obturages and be arranged on machine after circle and two grades of circles of obturaging
On cartridge case body, annular oil circuit can be obturaged.
The circular passage length of described annular oil circuit is casing inner surface upper straight segment length (L2) and axle
On bearing outer surface, annulus boss installs difference between back gauge (L1) to flange is 7-10mm.Annular oil circuit
Circular passage width is poor between casing inner surface top external diameter (Φ A) and bearing block lower outer diameter (Φ B)
1/2 be 2-4mm.
On described casing inner surface, the oblique angle of annular boss is 45 °, the annulus boss on bearing block outer surface
Oblique angle be 45 °.Sharp edge rounding polishing on casing inner surface and bearing block outer surface, radius r is 1mm.
The beneficial effects of the present invention is:
Using new structure, technique is more convenient, sealing ring uniform force when can guarantee that assembling, is difficult to be cut through,
The advantages such as good sealing effect.
