Abstract
The utility model relates to a bearing sealing device. A floating sealing ring is positioned between a bearing inner cap and a rotating shaft. A sealing ring that rotates with the rotating shaft is positioned on the rotating shaft outside the bearing inner cap. The excircle of the floating sealing ring is provided with a ring groove. An extension spring is arranged in the ring groove and the inner-circle and the rotating shaft are attached tightly through elastic deformation of the extension spring to ensure that the floating sealing ring moves up and down right and left along with the movement of the rotating shaft to realize dynamic sealing with the rotating shaft. The sealing ring is fixed on top and bottom through bolts. The inner hole of the sealing ring has certain interference relationship with the rotating shaft and rotates along with the rotating shaft to separate the rotating bearing from the inner side of motor to prevent the lubricating oil form leaking along the rotating shaft. The utility model has the advantages of simple structure, obvious effect and convenient maintenance.
Description
Technical field
The utility model relates to a kind of seal arrangement, especially a kind of associated sealing arrangement for bearings.
Background technique
Existing domestic used in high-speed motor sliding bearing in use occurs toward the phenomenon of the inboard leakage of oil of motor through regular meeting; especially motor speed is more than 1500 rev/mins the time; impeller both sides pressure differs, thus the lubricant oil that makes bearing cavity along rotating shaft toward motor in seepage.Bearing producer, motor producer have carried out many different design improvements for the bearing oil seepage phenomena at present, what have increases fine felt on internal bearing cover, adding in rotating shaft of having keeps off oil groove, what have increases oil baffle on bearing, though above-mentioned various design proposal produces certain effect in a short time, but motor is long-time running, and its final effect all is not very desirable.
Summary of the invention
The purpose of this utility model is a kind of simple in structure, associated sealing arrangement for bearings that effect is remarkable, easy to maintenance of design.The technical solution of the utility model is so to realize:
A kind of associated sealing arrangement for bearings, comprise bearing support (1), internal bearing cover (2), rotating shaft (6), be provided with a floating seal ring (3) between internal bearing cover (2) and the rotating shaft (6), the rotating shaft (6) in internal bearing cover (2) outside is provided with the seal ring (4) of a band projection (7) of therewith rotating.
As preferably, projection (7) is located in the groove (8) of internal bearing cover (2) one sides.
As preferably, floating seal ring (3) excircle is provided with circular groove (9), is provided with extension spring (10) in it.
As preferably, seal ring (4) is the branch half formula structure of two semi-rings, by being fixed in the rotating shaft (6) closing bolt (11).
As preferably, the gap of 1.3-1.7mm is arranged between projection (7) and the groove (8).
As preferably, the gap between projection (7) and the groove (8) is 1.5mm.
The utility model is provided with a floating seal ring (3) between internal bearing cover (2) and rotating shaft (6), the rotating shaft (6) in internal bearing cover (2) outside is provided with a seal ring (4) that changes together with rotating shaft (6), floating seal ring (3) is to be provided with a circular groove (9) by cylindrical, be provided with an extension spring (10) in the circular groove (9), by its elastic strain, circle is tightly fitted with rotating shaft (6) in making, thereby make floating seal ring (3) do up and down motion along with the motion of rotating shaft (6), dynamic seal (packing) between realization and the rotating shaft (6) effectively prevents oil impregnate.Seal ring (4) is the branch half formula structure of two semi-rings, by being fixed in the rotating shaft (6) closing bolt (11) up and down, there is certain interference relationship between seal ring (4) endoporus and the rotating shaft (6), rotate with rotating shaft (6), thereby bearing and motor inboard are separated, prevent that lubricant oil is along rotating shaft (6) seepage.The utility model is simple in structure, and effect is remarkable, and is easy to maintenance.
