Abstract
A lubrication crawler assembly, comprising a crawler plate, a bolt, a nut, a caterpillar link, a main crawler plate, a main link bolt, a main chain rail link of sleeve end, a main chain rail link of pin end, a pin bush, a cord junction ring, a U-shaped sealing ring, a thrust ring, a pin shaft and an end plug; the pin bushes between the main chain rail link of sleeve end and the adjacent main chain rail link of pin end are connected via the pin shaft and the pin bush; the pin shaft is inserted into an internal hole of the pin bush; the pin shaft is provided with an oil cavity; a transverse oil hole is drilled on the lateral wall of the pin shaft, so that the hypoid gear oil in the oil cavity enters into the clearance between the pin shaft and the pin bush; and the end plug is arranged on the external end of the oil cavity of the pin shaft. The utility model improves friction condition between the pin shaft and the pin bush, largely prolongs the service life of the crawler, is conveniently dismantled without using the pressing machine, reduces labor intensity of worker, and improves efficiency.
Description
Technical field
The utility model relates to a kind of track rail assembly, the lubricated track rail assembly that especially a kind of tracklaying vehicle is used.
Background technology
Existing track rail assembly is mainly the sealed type track rail assembly, is made up of chain rail joint, bearing pin, guide, seal ring, caterpillar block and bolt and nut; The effect of seal ring is to prevent that silt from getting into the space between bearing pin and the guide; Be the grease lubrication form between bearing pin and the guide, lubricated insufficient, the serious wear between the bearing pin guide; Cause the service life of crawler belt low, and watt loss is big.And track rail assembly adopts the less stub axle of a magnitude of interference that the two ends of crawler belt are linked together, this connection mode, dismounting difficulty.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of and improves assembling, reduces power consumption, improves the crawler belt lubricated track rail assembly in service life.
The purpose of the utility model realizes as follows: this lubricated track rail assembly; Comprise caterpillar block, bolt, nut, chain rail joint, main caterpillar block, main joint bolt, cover end main chain rail joint, pin end main chain rail joint, guide, concentration ring, U-shaped seal ring, thrust ring, bearing pin and end plug; Guide connected through bearing pin and guide between cover was held main chain rail joint and adjacent pin end main chain rail is saved; Bearing pin is inserted in the guide endoporus; Be provided with oil pocket in the bearing pin, on the bearing pin sidewall, be drilled with the horizontal oilhole that the hypoid gear oil that can make in the oil pocket gets into space between bearing pin and the guide, the oil pocket outer end of bearing pin is provided with end plug.Change existing seal ring into by U-shaped seal ring, concentration ring and thrust ring the poted assemblies of forming, poted assemblies is with seal between guide and the chain rail joint counterbore tightly.In use, hypoid gear oil can continual friction pair between bearing pin and guide, between bearing pin and guide, forms oil film, significantly reduces the wearing and tearing between the bearing pin guide.Guide designs for step, and is middle thick, and more high-abrasive material can be provided.Aspect assembling, design dissection type bidentate master joint, with main joint bolt with its be linked together.Reassembling type can be realized the separation or the connection of bidentate master joint as long as make unfasten with spanner or tight a bolt.
The utility model has improved the friction condition between bearing pin and the guide, makes prolong greatly the service life of crawler belt, and easy accessibility, need not to use pressing machine, reduces labor strength, raises the efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2; The utility model comprises caterpillar block 1, bolt 2, nut 3, chain rail joint 4, main caterpillar block 5, main joint bolt 6, cover end main chain rail joint 7, pin end main chain rail joint 8, guide 9, concentration ring 10, U-shaped seal ring 11, thrust ring 12, bearing pin 13 and end plug 14; Guide connected through bearing pin 13 and guide 9 between cover was held main chain rail joint 7 and adjacent pin end main chain rail is saved, and bearing pin 13 is inserted in guide 9 endoporus, is provided with oil pocket in the bearing pin 13; On bearing pin 13 sidewalls, be drilled with the hypoid gear oil that can make in the oil pocket and get into the horizontal oilhole in space between bearing pin 13 and the guide 9; The oil pocket outer end of bearing pin 13 is provided with end plug 14, through main joint bolt 6 be linked together cover end main chain rail joint 7 be dissection type bidentate structure with pin end main chain rail joint 8, guide 9 is a staircase structural model; Thin ends and thick middle, more high-abrasive material can be provided.In use; Hypoid gear oil gets into the faying face between bearing pin 13 and the guide 9 from the horizontal oilhole of bearing pin 13; Make and form one deck oil film between guide 9 and the bearing pin 13; Thereby improve the friction condition between guide 9 and the bearing pin 13, in the service life of improving crawler belt greatly, reduced the power of crawler belt internal consumption.When needing the dismounting crawler belt, only need to lead joint bolt 6 and unscrew and pull down, pull down main caterpillar block 5, make cover end main chain rail joint 7 and pin end main chain rail save 8 and separate and get final product.Caterpillar block 1 links through bolt 2 and nut 3 and chain rail joint 4.
