Description
Technical field
The utility model relates to bucket spindle technical field more particularly to a kind of excavator bucket spindles.
Background technique
In recent years, with the rapid development of economy, various project of reclamation by pumping filling are grown rapidly, since Chinese hydraulic excavator is started to walk
Later, although having become better and approaching perfection day by day on integrated artistic, still there are many aspects on local, the specific components of details
It needs to reinforce and improve.The working condition of digger operating device is low-speed heave-load, is covered to its connecting portion bucket spindle and bucket spindle
Working performance requires very high.Excavator bucket spindle is that the abrasion of full axle is maximum, according to correlation study statistics indicate that excavator bucket spindle
Average life is only less than 1,000 hours.Wherein excavator bucket spindle damage rate higher position, which is one, annoyings excavator manufacture
Quotient and the permanent problem of excavator user.It causes excavator bucket spindle to be easy the reason of losing and mainly includes two aspects that first, due to
The working environment of excavator is severe, and most of the time operation under Wetland Environment in mud-dumping yard, scraper bowl is often in contact with saliferous water
Biggish sandy soil are directly soaked in mud, and by brine corrosion, the intensity of its own can be a degree of impaired, and bucket spindle exists
It is easily destroyed during subsequent job, slurry mixture can also penetrate into bucket spindle system, cause machinery to bucket spindle system
Abrasion.Second, excavator bucket spindle requires daily plus butter is to keep lubricating, but in practical daily maintenance, due to oil transportation
The waste of difficult and a large amount of lubricating oil, few people can add lubricating oil to excavator bucket spindle daily, therefore solve the profit of bucket spindle
Sliding problem is extremely urgent.
Utility model content
In view of the deficienciess of the prior art, being solved the purpose of this utility model is to provide a kind of reasonable in design

As preferred: the iron gasket is identical with the outer diameter of the sealing ring.
By using above-mentioned technical proposal, the setting of iron gasket and sealing ring, it is ensured that lubricating oil will not from fixing end and
The junction of installation end leaks out, while also preventing the impurity such as sewage by entering bucket spindle body interior herein, to bucket spindle ontology
It damages.
As preferred: the mode that the plug cock plate is screwed is fixed on the opening of the oil filler point.
As preferred: the O-ring seal is made of rubber material.
By using above-mentioned technical proposal, the active force that bucket spindle ontology is subject to when due to excavator operation is big, bucket spindle ontology
Stronger vibration can be generated, therefore most important to the seal operation of oil filler point.O-ring seal made of rubber can be effectively
The disadvantage of leakproofness deficiency between metal material is made up, meanwhile, then it is screwed plug cock plate, plug cock plate can be effectively prevented
It falls off because the vibration of bucket spindle ontology is excessive.
Utility model has the advantages that 1. by the outer surface of installation end be arranged electroplated layer can be improved stability and
Corrosion resistance, and rough wear can be effectively prevented, improve greasy property；It, can be with 2. by the way that oil groove is arranged in installation end
So that the lubricating oil in installation end is evenly distributed, efficiently reduces the number for adding lubricating oil；3. fixing end is fixed by bolts and spiral shell
The fixed double fixed forms of line, greatly improve the stability of bucket spindle ontology, meanwhile, the diameter of threaded end is solid less than bolt
The diameter of fixed end is conducive to the quick positioning of fixing end；4. oil filler point is set on deck, it can be quick and convenient by oil filler point
Plus lubricating oil, in turn avoid the waste of lubricating oil；5. O-ring seal is arranged on oil filler point and by the fixed plug cock of screw
The leakproofness of oil filler point can be improved in plate, prevents the lubricating oil in oil groove from backflowing out of and comes.
