Abstract
The present invention relates to a kind of three-in-one sealing devices of axis, including transparent cover, sealing plate, outside framework oil seal, O-ring seal, disc, distance collar and drainback passage, outside framework oil seal and O-ring seal sealing of the transparent cover through its inner wall are worn the locking of spindle one end and are connected on upper and lower babinet, transparent cover outer end wear long spindle sealing plate locking encapsulation, distance collar is set between transparent cover and axis other end bearing support, disc corresponds to distance collar and is socketed on axis, lower box is equipped with the drainback passage for being connected to integral structure with distance collar, and drainback passage connection disc gets rid of oily cavity with spacing interannular.Its is simple in structure, can effectively prevent leakage, improves sealing performance.
Description
Technical field
The present invention relates to speed reducer structure field, specifically a kind of three-in-one sealing device of axis.
Background technology
The transmission rotation of the transmission shaft of speed reducer makes that oil leakage phenomenon, but the prior art can be avoided the occurrence of using oil-sealing arrangement
During central axis, oil sealing or ring structure are individually used, sealing effect is poor, and long-time service is easy to wear, and there are oil leaks
Hidden danger.
Invention content
The present invention provides a kind of simple in structure, leakage is can effectively prevent, the three-in-one sealing of axis for improving sealing performance fills
It sets.
The technical solution adopted by the present invention is：A kind of three-in-one sealing device of axis, it is characterised in that：Including transparent cover, sealing plate,
Outside framework oil seal, O-ring seal, disc, distance collar and drainback passage, outside framework oil seal and O-ring seal of the transparent cover through its inner wall
Sealing is worn the locking of spindle one end and is connected on upper and lower babinet, and transparent cover outer end wears long the sealing plate locking encapsulation of spindle, and distance collar is set to
Between transparent cover and axis other end bearing support, disc corresponds to distance collar and is socketed on axis, and lower box is equipped with distance collar and is connected to
The drainback passage of integral structure, drainback passage connection disc get rid of oily cavity with spacing interannular.
The drainback passage includes the axial passage on radial passage and lower box on the distance collar of connection, radial passage
Oily cavity is got rid of in connection, and axial passage is connected to upper and lower cabinets cavity.
The present invention uses outside framework oil seal and O-ring seal dual-seal from inside to outside, and cooperation disc will be by bearing support
It is got rid of with the fluid of axis periphery wall leakage to oily cavity is got rid of, is flowed back in decelerating chassis body by getting rid of oily channel, can effectively prevent lubrication
The leakage of fluid improves sealing performance.
Description of the drawings
Fig. 1 show schematic structural view of the invention.
In figure：Lower box 1, upper box 3, disc 4, O-ring seal 5, outside framework oil seal 6, gets rid of oily cavity 7, transparent cover at axis 2
8, sealing plate 9, spring bearing 10, radial passage 11, axial passage 12, distance collar 13.
Specific implementation mode
It is described further below in conjunction with drawings and examples.
Shown in Fig. 1：A kind of three-in-one sealing device of axis includes disc 4, O-ring seal 5, outside framework oil seal 6, gets rid of oily cavity
7, transparent cover 8, sealing plate 9, spring bearing 10, radial passage 11, axial passage 12, distance collar 13.Skeleton oil of the transparent cover 8 through its inner wall
Envelope 6 and the sealing of O-ring seal 5 are worn the locking of 2 one end of spindle and are connected on upper and lower babinet 3,1, and 8 outer end of transparent cover wears long the sealing plate of spindle 2
9 locking encapsulation, distance collar 13 are set between transparent cover 8 and axis other end bearing support 10, and disc 4 corresponds to distance collar and is socketed in axis
On, lower box 1 is equipped with the drainback passage for being connected to integral structure with distance collar 13, and drainback passage includes on the distance collar of connection
Axial passage 12 on radial passage 11 and lower box, the oily cavity that gets rid of of radial passage connection disc and spacing interannular are axial
Channel is connected to upper and lower cabinets cavity.
