Description
Technical field
The utility model relates to excavator technical fields, more particularly to excavator oil sealing pedestal.
Background technique
Excavator, also known as excavating machinery (excavating machinery), also known as excavator are higher than with scraper bowl excavation
Or lower than holding the material of machine side, and it is packed into haulage vehicle or unloads to the earthmoving machinery of rickyard.The material that excavator excavates is main
It is soil, coal, silt and soil and rock after pre- pine.From the point of view of the development of engineering machinery in recent years, excavator
Develop relatively fast, excavator has become one of most important engineering machinery in engineering construction.Excavator needs machine oil to provide
Power, so needing key design for the design of oil sealing, on the current technology, oil sealing tightness of bases is not so good, and
Fuel tank service life reduces, and influences the normal work of excavator.
Utility model content
The purpose of this utility model is that solve the above-mentioned problems and provides excavator oil sealing pedestal.
The utility model achieves the above object through the following technical schemes:
Excavator oil sealing pedestal, including wheel hub cover, retaining ring, sealing device, the wheel hub cover top are provided with plug cock,
It is provided with locknut below the wheel hub cover, is provided with the retaining ring, the retaining ring two sides below the locknut

Wear ring is arranged in disc spring, the disc spring lower section, and the sealing device, the sealing dress are arranged below the wear ring
Chuck is arranged in bottom set portion.
In above structure, by adjusting the locknut, to control the locking degree of the retaining ring, the locator
Guarantee the job schedule of pedestal, when by certain pressure, the disc spring provides cushion effect, and the sealing device guarantees
Oil sealing is more thorough.
In order to further increase oil sealing effect, the wheel hub cover bottom is connected by screw to the plug cock, in the plug cock
Mandrel and the locknut are coaxial, are detachably connected the O-ring below the locknut, the locknut with it is described
The fit system of O-ring is basic hole system.
In order to further increase oil sealing effect, the connection type of the O-ring and the retaining ring is welding, the locking
The fit system of ring and the bearing is basic shaft system.
In order to further increase oil sealing effect, the locator, the locator and the disk are welded in the bearing bottom
The connection type of shape spring be it is hinged, one end of the disc spring is soldered to the wear ring.
In order to further increase oil sealing effect, the sealing device is welded in the wear ring side, the sealing device
Bottom is by being pivotally connected to the chuck.
The utility model has the beneficial effects that: by the design to retaining ring and sealing device, so that oil sealing pedestal is close
Envelope property is more preferable, and improves the service life of oil tank of excavating machine.
