Abstract
The utility model relates to a header joint bearing seal structure, include and be high -speed reciprocal pendulum motion joint bearing with centre point A, joint bearing's both ends install the dust ring respectively additional, shield seam subassembly and shield are equipped with respectively to the outer end of dust ring, shield seam subassembly and shield are fixed by bolt and joint bearing seat subassembly. The utility model discloses the leakproofness is good, three total sealed measures on this structure, very big improvement joint bearing's life.
Description
Technical field
The utility model is related to sealing structure and in particular to a kind of ceding of Taiwan oscillating bearing sealing structure.
Background technology
Before corn silage harvester, ceding of Taiwan cutting blade is reciprocating, produces larger inertia force and shock loading,
The service life of the oscillating bearing that each part of cutter itself especially transmits power is had a significant impact, though through inertia force
Balance Treatment, but in practice, the damage parts of this structure are still quite serious.Especially ceding of Taiwan fork oscillating bearing sealing effectiveness
Bad, dust inlet is big it is impossible to guarantee oscillating bearing cleans, and affects the service life of bearing further, has a strong impact on whole machine
The reliability using.
Utility model content
For solving the above problems, the utility model provides a kind of good airproof performance, and the ceding of Taiwan oscillating bearing of long service life is close
Seal structure.
The technical solution of the utility model
A kind of ceding of Taiwan oscillating bearing sealing structure, does high speed oscillating traverse motion oscillating bearing including with centre point a, described
The two ends of oscillating bearing install dust ring respectively additional, and the outer end of described dust ring is respectively provided with dust cap seam assembly and dust cap,
Described dust cap seam assembly and dust cap are fixed with oscillating bearing holder assembly by bolt.
Further, described bolt is hexagonal slotting bolt.
The beneficial effects of the utility model
The utility model good airproof performance, installs dust ring additional respectively at the two ends of oscillating bearing, and this is the second of oscillating bearing
Road seals, and is respectively provided with dust cap seam assembly and dust-proof in the outer end of dust ring, dust cap seam assembly and dust cap are by spiral shell
Bolt is fixed with oscillating bearing holder assembly, and under the active force of bolt, dust cap seam assembly and dust cap are produced with dust ring and squeeze
Pressure, thus reach sealing effectiveness.This structure of seal approach plus oscillating bearing itself has three seals measure, greatly carries
The high service life of oscillating bearing.This structure has three seals measure, greatly improves the service life of oscillating bearing.
Brief description
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, 1- oscillating bearing holder assembly, 2- oscillating bearing, 3- dust ring, 5- dust cap seam assembly, 6- bolt,
7- dust cap, 8- arm shaft.
Specific embodiment
As shown in figure 1, a kind of ceding of Taiwan oscillating bearing sealing structure, close including high speed oscillating traverse motion is done with centre point a
Bearings 2, the two ends of described oscillating bearing 2 install dust ring 3 respectively additional, and the outer end of described dust ring 3 is respectively provided with dust cap weldering
Seaming element 5 and dust cap 7, described dust cap seam assembly 5 and dust cap 7 are fixed with joint bearing block 2 assembly by bolt 6.Institute
Stating bolt 6 is hexagonal slotting bolt.
Operationally, oscillating bearing holder assembly 1 is promoted by external force and does high speed alternating translational movement, joint ceding of Taiwan oscillating bearing
Bearing 2 and arm shaft 8 assembly do high speed oscillating traverse motion with centre point a, because working environment compares evil slightly although oscillating bearing
2 have certain seal approach in itself, but the service life of oscillating bearing 2 is far from before not increasing extra seal approach
Enough.Install dust ring 3 at the two ends of oscillating bearing 2 respectively additional, this is the second sealing of oscillating bearing, in the outer end of dust ring 3
It is respectively provided with dust cap seam assembly 5 and dust-proof 7, dust cap seam assembly 5 and dust cap 7 are by bolt 6 and joint bearing block group
Part 1 is fixing, and under the active force of bolt 6, dust cap seam assembly 5 and dust cap 7 produce extruding with dust ring 3, thus reaching close
Envelope effect.Have three seals measure plus oscillating bearing 2 this structure of the seal approach of itself, greatly improve oscillating bearing
2 service life.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or new using this practicality
Type.Multiple modifications to these embodiments will be apparent from for those skilled in the art, is determined herein
The General Principle of justice can be realized in the case of without departing from spirit or scope of the present utility model in other embodiments.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The wide scope consistent with features of novelty.
