The step surface that shield device seat is equipped with is in contact, and the outer end face of water proof and dust proof ring is equal with a side end face of bearing protector seat
Together；The inner cavity of the bearing protector seat is J-type collecting chamber, and lubrication oil sump tank is equipped in the bottom of the J-type collecting chamber；Institute
Contact surface between the bearing protector seat stated and axis uses labyrinth seal structure, and the labyrinth seal is by sealing runner and cone
Shape oil-recovery tank is connected；The water proof and dust proof ring forms static seal, the transmission seal circle with axis by transmission seal circle and axis
In the groove that water proof and dust proof ring is opened up, and it is coated with grease outside；The outer circle of the water proof and dust proof ring is machined with inwardly
Twice annular groove, the twice annular groove are in clearance fit with bearing protector seat, which communicates with return flume.
Preferably, the angles R of anti-channeling positioning are equipped at the end angle of the water proof and dust proof ring, and the water proof and dust proof ring is by can
Deformation nonmetallic materials are made.
If being formed in the small gap that grade is distributed preferably, the labyrinth seal of the bearing protector seat is arterial highway,
It is connected between the small gap by sealing runner, and the small gap is arranged in order in the axial direction of bearing protector seat.
Beneficial effects of the present invention are：Realize anti-lubricating oil leakage, rainwater-proof, dust enter bearing, it is ensured that bearing is permanent
Reliability service.

Specific implementation mode
Detailed introduction is done to the present invention below in conjunction with attached drawing：As shown in Fig. 1, the present invention is by bearing protector seat 1
The hybrid Bidirectional seal structure being composed with water proof and dust proof ring 5, the bearing protector seat 1 and water proof and dust proof ring 5 according to
Secondary to be installed on axis 6, the inner face of the water proof and dust proof ring 5 is in contact with the step surface 11 that bearing protector seat 1 is equipped with, and anti-
The outer end face of water dust ring 5 and a side end face flush of bearing protector seat 1；The inner cavity of the bearing protector seat 1 is J
Type collecting chamber 2 is equipped with lubrication oil sump tank 3 in the bottom of the J-type collecting chamber 2；Between the bearing protector seat 1 and axis 6
Contact surface use 4 structure of labyrinth seal, and the labyrinth seal 4 by seal runner be connected with taper oil-recovery tank 10；It is described
Water proof and dust proof ring 5 and axis 6 static seal is formed by transmission seal circle 7 and axis 6, which is located at water proof and dust proof ring 5
In the groove 51 opened up, and it is coated with grease outside；The outer circle of the water proof and dust proof ring 5 is machined with twice annular groove inwardly
52, which is in clearance fit with bearing protector seat 1, which communicates with return flume 9.
The angles R 8 of anti-channeling positioning are equipped at the end angle of the water proof and dust proof ring 5, and the water proof and dust proof ring 5 is by deformable non-
Metal material is made.
If it is in that the equal small gap 41 being distributed forms that the labyrinth seal 4 of the bearing protector seat 1, which is arterial highway, the crack
It is connected between gap 41 by sealing runner, and the small gap 41 is arranged in order in the axial direction of bearing protector seat 1.
The installation method and operation principle of the present invention is as follows：1 inner cavity of bearing protector seat uses J-type, when making bearing operation
Most of lubricating oil flow direction lubrication oil sump tank 3 of splashing returns to oil sump；Labyrinth is used between bearing protector seat 1 and axis 6
4 forms are sealed, are designed to tortuous small gap 41, when operating forms the great one section of runner of flow resistance at sealing, is left
The lubricating oil that small part sputters can encounter prodigious resistance herein, to generate throttle effect, make the speed of lubricating oil not
Disconnected to weaken, the lubricating oil after decrease enters oil sump along sealing runner trickling through taper oil-recovery tank 10, to prevent lubricating oil
Leakage；Water proof and dust proof ring 5 is using the angles R 8 and utilizes deformable nonmetallic elastic conjunction, and water proof and dust proof ring 5 passes through transmission with axis 6
Sealing ring 7 forms static seal with axis 6, (applies and oils in assembling by 7 elasticity of transmission seal circle and using oil swell material is met
Fat) realize axis 6 and water proof and dust proof ring 5 transmission.The material of water proof and dust proof ring 5 is nonmetallic, light-weight, reliable transmission, assembly
As long as when bearing protector seat 1 and water proof and dust proof ring 5 and 7 component of transmission seal circle loaded on body in place after, firmly pressing is anti-
Water dust ring 5 makes water proof and dust proof ring 5 be contacted with the step surface 11 of bearing protector seat 1, then unclamps, utilizes transmission seal circle 7
Small resilience, have a minimum gap between step surface 11, not only reliably sealed together for oil pocket and external increase again
Barrier, and can also prevent the outer of water proof and dust proof ring 5 from altering.5 outer circle of water proof and dust proof ring processes twice annular groove 52 inwardly, with axis
The cooperation of 1 small―gap suture of protector seat is held, another section of labyrinth is formed, atmospheric environment is made to become more tortuous more to the leakage paths of bearing
Become, the water and other pollutants in air can deposit herein, be flowed out through return flume 9, will not enter bearing housing, final to realize
Anti- lubricating oil leakage, rainwater-proof, dust enter bearing, it is ensured that the permanent reliability service of bearing.
It is understood that it will be understood by those skilled in the art that being subject to technical scheme of the present invention and inventive concept
The protection domain of appended claims of the invention should all be belonged to replacement or change.
