Description
Technical field
The utility model relates to speed reducer structure field, specifically a kind of three-in-one sealing device of axis.
Background technique
The transmission rotation of speed reducer driving shaft avoids the occurrence of oil leakage phenomenon using oil-sealing arrangement, but prior art axis turns
During dynamic, oil sealing or ring structure are individually used, poor sealing effect, long-time service is easy to wear, and there are oil leak hidden danger.
Summary of the invention
It is simple that the utility model provides a kind of structure, can effectively prevent leakage, the axis for improving sealing performance is three-in-one close
Seal apparatus.
The technical solution adopted in the utility model 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, the outside framework oil seal and O-ring seal of transparent cover inner wall
Spindle one end is worn in sealing, and transparent cover locking connects on upper and lower cabinet, and the sealing plate locking encapsulation of spindle, distance collar are worn in transparent cover outer end
It is set between transparent cover and axis other end bearing support, disc corresponds to distance collar and is socketed on axis, sets on lower box and distance collar
There is the drainback passage of connection integral structure, drainback passage connection disc gets 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 utility model uses outside framework oil seal and O-ring seal dual-seal from inside to outside, and cooperation disc will be by supporting
Bearing and the oil liquid of axis periphery wall leakage are got rid of to oily cavity is got rid of, and are flowed back in decelerating chassis body, be can effectively prevent by getting rid of oily channel
The leakage of lubricating oil improves sealing performance.
Detailed description of the invention
Fig. 1 show the utility model structure diagram.
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 embodiment
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.The outside framework oil seal 6 of 8 inner wall of transparent cover
2 one end of spindle is worn with the sealing of O-ring seal 5, transparent cover locking connects on upper and lower cabinet 3,1, and 8 outer end of transparent cover is through wearing the envelope of spindle 2
The locking encapsulation of plate 9, distance collar 13 are set between transparent cover 8 and axis other end bearing support 10, and the corresponding distance collar of disc 4 is socketed in
On axis, 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
Radial passage 11 and lower box on axial passage 12, radial passage connection disc and spacing interannular get rid of oily cavity, axis
Upper and lower cabinets cavity is connected to channel.
