Abstract
The utility model provides an axle center anti-leakage device of a bearing. The axle center anti-leakage device is suitable for fluid (liquid) dynamic pressure bearings and ordinary oil bearings. The bearing base internally comprises the bearing, an axle center, an anti-pulling buckle, an anti-leakage pressing plate and at least one anti-leakage loop which is located on the axle center inside the bearing base, and an inner ring face of the anti-leakage loop is contacted but not in linkage with the outer wall of the axle center. The occurrence that oil slick overflows outwards is effectively prevented, wherein the oil slick is formed by the fact that lubrication fluid (liquid) in the bearing flows along the axle center caused by rotation of the axle center. The problem of running off of the lubrication fluid (liquid) in the bearing is solved, and good using benefits and long service life of the bearing are ensured.
Description
Technical field
The utility model relates to a kind of axle center resistance neglected loading of bearing to be put, and can be widely used in stream (liquid) body hydraulic bearing and general oil-impregnated bearing.
Background technique
The structure of known relevant stream (liquid) body hydraulic bearing and general oil-impregnated bearing, be in bearing support, to insert bearing (the shaft hole inner wall face of hydraulic bearing is provided with the guide channel that produces the dynamic pressure effect, the shaft hole inner wall face of general oil-impregnated bearing then is a hydraulically smooth surface) and the axle center, cooperate filling stream (liquid) body and the anti-involution that pulls out button and leakproof pressing plate, and form a stream (liquid) body hydraulic bearing or oil-impregnated bearing structure.
Yet in the prior art, except having reached main bearing effectiveness, after using a period of time, the outside leakage problems of bearing inner stream (liquid) body, then slowly do not give perfect solution, to such an extent as to stream (liquid) body hydraulic bearing is in use for some time, often run off because of the seepage of inside stream (liquid) body that benefit lowers in addition therefore fault scrap, cause the limited of the shortening of life of product and utilization benefit.
In the bearing block structure that has sealed, the seepage that still can produce inner stream (liquid) body runs off, main cause is: all having a small slit between static each assembly of bearing support and the axle center of rotation, is that the issuable gas in bearing support inside effluxes during for the smooth and easy rotation that do not hinder the axle center and axle center high speed rotating.Also, just become stream (liquid) body leak path in order to stop leakproof pressing plate and the slit between the axle center that inner stream (liquid) body seepage runs off because so.
When the axle center rotated, stream (liquid) cognition of the inner institute of bearing support filling was being followed the axle center appearance and is being formed the film shape and the slime flux that makes progress, and after a period of time, outside seepage runs off this stream (liquid) body thin film by the slit between leakproof pressing plate and axle center.
In the prior art, existing utilize the axle center to establish a scrobicular ring to be enclosed button one and be integral the falope ring of interlock in the hope of reaching blocking effect with the axle center, but following make progress stream (liquid) body thin film of slime flux of axle center appearance and still can cross the falope ring of this one interlock, and running off by the outside seepage in the slit between leakproof pressing plate and axle center.
In addition, settling mode at the lower oil-impregnated bearing of precision requirement then is: strengthening oil storage space or can be increased the service life by the means of outer filling, but this kind mode and means still can't actual solutions: the problem that stream (liquid) body runs off by the gap leakage between this leakproof pressing plate and axle center.
The model utility content
The utility model purpose is, provides a kind of inner stream of bearing (liquid) body of can effectively blocking to form the outside slime flux of oil film along the axle center, avoids causing the axle center resistance neglected loading of the bearing that filling stream (liquid) body runs off in the bearing to put.
In order to achieve the above object, the utility model provides a kind of axle center resistance neglected loading of bearing to put, bearing support include the bearing that places bearing support inside, tandem arrangement in the axle center of a bearing centre and a distal process projecting shaft bearing outside, be arranged in anti-that bearing top and location card be buckled in the axle center scrobicular ring and pull out button, be arranged in and prevent pulling out bearing support was put and sealed by the side of buckling with pressure leakproof pressing plate, the axle center of described bearing support inside is provided with at least one resistance and leaks ring, and this resistance leaks that ring inner ring surface contacts with the axle center outer wall and interlock not.
Further, this bearing can be hydraulic bearing, oil-impregnated bearing.
The utility model also provides a kind of axle center resistance neglected loading of bearing to put, bearing support includes the bearing that places bearing support inside, tandem arrangement is in the axle center of a bearing centre and a distal process projecting shaft bearing outside, be arranged in bearing top and location card and be buckled in the anti-button that pulls out of axle center scrobicular ring, be arranged in anti-bearing support was put and sealed by the side of buckling with pressure the leakproof pressing plate that pulls out, the axle center of described bearing support inside is provided with at least one resistance and leaks ring, described leakproof pressing plate internal ring wall be provided with at least one circle for resistance leak ring hold into the scrobicular ring ditch, the horizontal internal diameter of scrobicular ring ditch leaks the horizontal external diameter of ring greater than resistance, vertical internal diameter of scrobicular ring ditch leaks vertical external diameter of ring greater than resistance, described resistance is leaked ring and is located in the scrobicular ring ditch of leakproof pressing plate internal ring wall, and this resistance leaks that ring inner ring surface contacts with the axle center outer wall and interlock not.
Further, this bearing can be hydraulic bearing, oil-impregnated bearing.
The utility model has been blocked hydraulic bearing and general oil-impregnated bearing effectively, and filling stream (liquid) body forms the outside slime flux of oil film in the bearing along the axle center because of the axle center rotation makes, solved the problem that filling stream (liquid) body runs off in the bearing, advanced to have guaranteed the longer utilization benefit and the life-span of bearing.
