Abstract
The utility model relates to an oil seal shaft sleeve, comprising: a ceramic shaft sleeve and a rubber oil seal, wherein the ceramic shaft sleeve is used for a shaft sealing part arranged on a sealing mounting base, and the rubber oil seal is arranged between the ceramic shaft sleeve and the shaft. The utility model is provided with the ceramic shaft sleeve at the shaft sealing part under a condition that the structure and the size of the prior sealing mounting base are not changed; novel seal is formed by selecting oil seal which is matched with the ceramic shaft sleeve. Because of high hardness of the ceramic shaft sleeve, friction coefficient of a moving seal friction surface is greatly reduced in use, thereby improving service life of the oil seal, and greatly reducing operation cost and maintenance cost only for replacing the shaft sleeve without replacing the shaft because of abrasion of a shaft journal in maintaining at the same time.
Description
Technical field
The utility model relates to a kind of oil sealing axle sleeve.
Background technique
Existing axial workpiece directly contacts with axle journal with the sealing lip of oil sealing, in use often because of friction causes journal wear, thereby causes seal failure, must overhaul and change axle and oil sealing, maintenance cost height.
The model utility content
Technical problem to be solved in the utility model provides a kind of friction factor of motive sealing rubbing surface that reduces to improve the oil sealing oil sealing axle sleeve in working life.
For solving the problems of the technologies described above, oil sealing axle sleeve of the present utility model comprises: be used to be arranged on the sealing fitting seat the shaft sealing position Ceramic shaft sleeve and be used to be arranged on rubber oil sea between Ceramic shaft sleeve and the axle.
In the technique scheme, the rough surface of described Ceramic shaft sleeve.
The utlity model has positive effect: (1) the utility model is under the situation of structure that does not change former sealing fitting seat and axle and size, a Ceramic shaft sleeve is installed at the shaft sealing position, and select the oil sealing that matches with this Ceramic shaft sleeve for use, form new sealing, because Ceramic shaft sleeve hardness height, greatly reduce the friction factor of motive sealing rubbing surface in the use, so improved the working life of oil sealing.Simultaneously, when maintenance, needn't change axle, only need change axle sleeve, greatly reduce utilization and maintenance cost because of the wearing and tearing of axle journal.(2) in the utility model, the rough surface of Ceramic shaft sleeve can further reduce the friction factor of motive sealing rubbing surface, and improves the working life of oil sealing.
Description of drawings
Fig. 1 is the application structure schematic representation of oil sealing axle sleeve.
Embodiment
(embodiment 1)
See Fig. 1, the oil sealing axle sleeve of present embodiment comprises: be used to be arranged on sealing fitting seat (1) the shaft sealing position Ceramic shaft sleeve 2 and be used to be arranged on rubber oil sea 4 between Ceramic shaft sleeve 2 and the axle 3.Under the situation of structure that does not change former sealing fitting seat and axle and size, a Ceramic shaft sleeve is installed at the shaft sealing position, and select the oil sealing that matches with this Ceramic shaft sleeve for use, form new sealing, because Ceramic shaft sleeve hardness height, greatly reduce the friction factor of motive sealing rubbing surface in the use, so improved the working life of oil sealing.Simultaneously, when maintenance, needn't change axle, only need change axle sleeve, greatly reduce utilization and maintenance cost because of the wearing and tearing of axle journal.
The rough surface of described Ceramic shaft sleeve 2 can further reduce the friction factor of motive sealing rubbing surface, and improves the working life of oil sealing.
Claims (2)
1, a kind of oil sealing axle sleeve is characterized in that: comprise the Ceramic shaft sleeve (2) at the shaft sealing position that is used to be arranged on sealing fitting seat (1) and be used to be arranged on rubber oil sea (4) between Ceramic shaft sleeve (2) and spool (3).
2, oil sealing axle sleeve according to claim 1 is characterized in that: the rough surface of described Ceramic shaft sleeve (2).
