Abstract
The utility model discloses a sealing device for preventing lubricating oil leakage of a motor bearing, wherein a bearing outer cover and a bearing inner cover are arranged at two sides of the bearing, the bearing outer cover, a motor end cover and the bearing inner cover are fixedly connected, and an oil thrower is positioned between the bearing outer cover and the bearing; one side of the oil thrower disc is provided with a groove in a surrounding mode, oil thrower protrusions are arranged on the outer circumference of the oil thrower disc in a surrounding mode, and the groove of the oil thrower disc is meshed with the convex teeth arranged on the inner side of the outer bearing cover in a surrounding mode. The utility model discloses a prevent that the lubricating oil of bearing hole department from leaking, save the oil blanket, adopt the disc structure, highly sealed is realized with the inboard dogtooth interlock of bearing enclosing cover to the disc, has blocked and has been stained with the route of outwards leaking at the epaxial lubricating oil of changeing, after the disc was touch to the epaxial lubricating oil of changeing, got rid of the edge to the disc under the effect of centrifugal force, has left bearing hole department, the phenomenon of the lubricating oil leakage of bearing hole department that has significantly reduced, and the motor speed of rotation is higher the oil throwing effect is better.
Description
Technical Field
The utility model relates to the technical field of motors, especially, relate to a motor bearing prevents lubricating oil leakage sealing device.
Background
In order to prevent lubricating oil from leaking outwards along the extending rotating shaft in the motor, an oil seal is usually installed on a shaft outlet hole of a bearing cover of the motor and clings to a shaft neck extending out of the bearing cover, but along with the increase of the running time of the motor, the phenomenon that the lubricating oil of the bearing leaks outwards through the rotating shaft can occur due to the aging of the oil seal.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned problem, provide a motor bearing prevents lubricating oil leakage sealing device.
In order to solve the technical problem, the technical scheme of the utility model is that: the sealing device for preventing the lubricating oil leakage of the motor bearing comprises a rotating shaft, a bearing outer cover, an oil thrower, a retainer ring, a bearing inner cover and a motor end cover; a retainer ring annular groove is formed in the outer circumference of the rotating shaft, and a retainer ring is arranged in the retainer ring annular groove; the rotating shaft is sleeved with a bearing outer cover, an oil thrower, a bearing and a bearing inner cover, the bearing is positioned in the motor end cover, the bearing outer cover and the bearing inner cover are arranged on two sides of the bearing, the bearing outer cover, the motor end cover and the bearing inner cover are fixedly connected, and the oil thrower is positioned between the bearing outer cover and the bearing; a groove is formed in one side of the oil thrower disc in a surrounding mode, oil thrower protrusions are arranged on the outer circumference of the oil thrower disc in a surrounding mode, and the groove of the oil thrower disc is meshed with convex teeth arranged on the inner side of the outer bearing cover in a surrounding mode; the retainer ring is positioned between the bearing outer cover and the oil thrower.
Furthermore, an oil thrower is arranged on the rotating shaft by a hot sleeve method.
Further, the bearing outer cover, the motor end cover and the bearing inner cover are fixedly connected through bolts.
The utility model discloses a prevent that the lubricating oil of bearing hole department from leaking, save the oil blanket, adopt the disc structure, highly sealed is realized with the inboard dogtooth interlock of bearing enclosing cover to the disc, has blocked and has been stained with the route of outwards leaking at the epaxial lubricating oil of changeing, after the disc was touch to the epaxial lubricating oil of changeing, got rid of the edge to the disc under the effect of centrifugal force, has left bearing hole department, the phenomenon of the lubricating oil leakage of bearing hole department that has significantly reduced, and the motor speed of rotation is higher the oil throwing effect is better.

Detailed Description
The following describes the embodiments of the present invention with reference to fig. 1 and 2.
The motor bearing lubricating oil leakage prevention sealing device comprises a rotating shaft 1, a bearing outer cover 2, an oil thrower 3, a retainer ring 4, a bearing inner cover 5 and a motor end cover 6; a retainer ring annular groove is formed in the outer circumference of the rotating shaft 1, a retainer ring 4 is installed in the retainer ring annular groove through a shrink fit method, and the retainer ring 4 axially limits the oil thrower 3; the rotating shaft 1 is sleeved with a bearing outer cover 2, an oil thrower 3, a bearing and a bearing inner cover 5, the bearing is positioned in a motor end cover 6, the bearing outer cover 2 and the bearing inner cover 5 are arranged on two sides of the bearing, the bearing outer cover 2, the motor end cover 6 and the bearing inner cover 5 are fixedly connected through bolts, and the oil thrower 3 is positioned between the bearing outer cover 2 and the bearing; a groove is formed in one side of the oil thrower disc 3 in a surrounding mode, oil thrower protrusions are arranged on the outer circumference of the oil thrower disc 3 in a surrounding mode, and the groove of the oil thrower disc 3 is meshed with convex teeth arranged on the inner side of the bearing outer cover 2 in a surrounding mode; the collar 4 is located between the bearing outer cover 2 and the oil slinger 3.
The oil throwing disc 3 blocks a path for outwards leaking lubricating oil stained on the rotating shaft 1, and after the lubricating oil on the rotating shaft 1 touches the oil throwing disc 3, the lubricating oil is thrown to the edge of the oil throwing disc 3 under the action of centrifugal force and leaves from the bearing hole, so that the phenomenon of leakage of the lubricating oil at the bearing hole is greatly reduced.
Above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the design of the present invention, equivalent replacement or change should be covered within the protection scope of the present invention.
