Abstract
The invention discloses a bearing box body with a floating isolating ring in an oil cavity. The bearing box body comprises a shaft (3), an isolating ring (4) and a hole retainer ring (5), wherein the isolating ring (4) is arranged inside the oil cavity of the bearing box body (1) and is limited to rotate by a pin (2) which is fixed on the bearing box body (1), one side of the isolating ring (4) is positioned by an end surface processed by the bearing box body (1), and the other side of the isolating ring (4) is positioned by the hole retainer ring (5) which is arranged on the bearing box body (1). By adopting the bearing box body with the floating isolating ring in the oil cavity, disclosed by the invention, the condition that impurities generated by friction damage a bearing can be avoided, simultaneously, the sealing effect can be ensured for a long time.
Description
Technical field
The present invention relates in a kind of oil pocket the bearing housing with the isolating ring that floats.
Background technique
In prior art, the bearing housing that has adjacent two oil pockets is often arranged in mechanical structure, axle passes from oil pocket, there is pressure reduction in two oil pockets, thereby require two oil pockets that passed by axle are carried out permanently effective isolating seal, sealing is placed in the middle of oil pocket, can be lubricated by the lubricant oil in bearing housing, should not guarantee simultaneously to seal to produce impurity pollution lubricating oil damage bearing because of the friction between static pieces.
Summary of the invention
The purpose of this invention is to provide a kind of can avoid rubbing produce the impurity damage bearing simultaneously in the long-term oil pocket that guarantees sealing effect with the bearing housing of the isolating ring that floats.
The technological scheme that the present invention adopts for achieving the above object is: in a kind of oil pocket with the bearing housing of the isolating ring that floats, comprise axle (3), isolating ring (4) and hole back-up ring (5), described isolating ring (4) is arranged in the oil pocket of bearing housing (1), described isolating ring (4) rotates by pin (2) restriction that is fixed on bearing housing (1), the end face location that one side of described isolating ring (4) is processed by bearing housing (1), opposite side is located with back-up ring (5) by the hole that is arranged on bearing housing (1).
Leave the gap of 0.05mm-0.1mm between described axle (3) and isolating ring (4).
Be provided with the gap of 0.5mm-1mm between described isolating ring (4) and bearing housing (1).
Described isolating ring (4) and hole are with reserving the gap of 0.3mm-0.5mm at least between back-up ring (5).
With the bearing housing of the isolating ring that floats, can avoid friction to produce the impurity damage bearing long-term sealing effect that guarantees simultaneously in a kind of oil pocket of the present invention.
Description of drawings
Fig. 1 is with the structural representation of the bearing housing of the isolating ring that floats in a kind of oil pocket of the present invention.
Fig. 2 is with the partial enlarged drawing of the isolating ring structure of the bearing housing of the isolating ring that floats in a kind of oil pocket of the present invention.
Fig. 3 is that the B-B of Fig. 1 is to view.
In figure: 1, bearing housing; 2, pin; 3, axle; 4, isolating ring; 5, hole back-up ring; 6, oil pocket.
Embodiment
as depicted in figs. 1 and 2, in oil pocket with the bearing housing of the isolating ring that floats, comprise axle 3, isolating ring 4 and hole back-up ring 5, isolating ring 4 is arranged in the oil pocket of bearing housing 1, isolating ring 4 rotates by pin 2 restrictions that are fixed on bearing housing 1, the end face location that one side of described isolating ring 4 is processed by bearing housing 1, opposite side is located with back-up ring 5 by the hole that is arranged on bearing housing 1, unsteady isolating ring structure in oil pocket 6 is that isolating ring 4 can not rotate, can radial floating, produce liquid film during running between axle 3 and isolating ring 4, avoid the wearing and tearing of axle 3 and isolating ring 4, but isolating ring 4 and axle 3 self-alignings, allow to arrange between isolating ring 4 and axle 3 very little gap, close clearance produces very large resistance and realizes sealing, greatly reduced dredge oil amount, simultaneously isolating ring 4 and axle 3 can self-alignings, avoid eccentric wear to produce the impurity damage bearing, simultaneously can keep for a long time very little gap, improve sealing effect, leave very large gap between axle 3 and bearing housing 1, axle 3 and bearing housing 1 contact wear in avoiding rotating, leave very little gap between axle 3 and isolating ring 4, general 0.05～0.1mm, thereby close clearance produces very large oil film resistance and realizes sealing, isolating ring 4 is by being fixed on the pin 2 restriction anti-rotations on bearing housing 1, isolating ring 4 is provided with larger radial clearance with bearing housing 1, general 0.5～1mm, can radial floating during assurance work, thereby realize the self-aligning between isolating ring 4 and axle 3, the wearing and tearing of 4 of axle 3 and isolating rings can not appear, isolating ring 4 needs axially locating, the end face location that one side is processed by bearing housing 1, opposite side is located with back-up ring 5 by the hole, in order to realize floating of isolating ring 4, when isolating ring 4 and bearing housing 1 axially locating, need to reserve enough gaps, namely when isolating ring 4 right sides and bearing housing 1 locating face are adjacent to, isolating ring 4 and hole will reserve at least 0.3～0.5 gap with 5 of back-up rings, the present invention can avoid rubbing and produce the impurity damage bearing long-term sealing effect that guarantees simultaneously.
Claims (4)
- In an oil pocket with the bearing housing of the isolating ring that floats, it is characterized in that: comprise axle (3), isolating ring (4) and hole back-up ring (5), described isolating ring (4) is arranged in the oil pocket of bearing housing (1), described isolating ring (4) rotates by pin (2) restriction that is fixed on bearing housing (1), the end face location that one side of described isolating ring (4) is processed by bearing housing (1), opposite side is located with back-up ring (5) by the hole that is arranged on bearing housing (1).
- In a kind of oil pocket according to claim 1 with the bearing housing of the isolating ring that floats, it is characterized in that: the gap of leaving 0.05mm-0.1mm between described axle (3) and isolating ring (4).
