Description
Technical field
The utility model relates to guide production technical field more particularly to a kind of crawler of excavator guidees.
Background technique
Crawler of excavator guide is hollow shaft structure in the prior art, due to excavator own wt, bearing capacity when work
Greatly and excavator tooling reason, big to the extruding force at crawler of excavator guide both ends when excavator works, make guide both ends
It is easily deformable, to the pin-shaped in guide at frictional resistance, the working efficiency of excavator is influenced, shorten excavator uses the longevity
Life.Further, since structure limits, cooperate between guide inner hole and pin shaft for small―gap suture, oil reserve between the two is limited, easily produces
The phenomenon that raw insufficient lubrication, the abrasion between pin shaft and guide can be accelerated.
Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of crawler of excavator guide.
In order to achieve the above object, the utility model adopts the following technical solutions: a kind of crawler of excavator guide, including guide
Ontology, guide ontology are hollow shaft structure, and the hollow shaft inner hole surface of guide ontology is using the geometric center of guide ontology as a basic point left side
It is right symmetrical, it is oil storage section in the middle part of the hollow shaft inner hole surface of guide ontology, oil storage section both ends are connected with tilting section, and tilting section is far from oil storage
One end of section is connected with cylindrical section, and cylindrical section is connected with horn mouth conical section, and horn mouth conical section inner hole far from one end of tilting section
The bevel angle in face is not more than 5 °, and horn mouth conical section is greater than the diameter of the other end close to the diameter of one end of guide ontology port,
The port diameter that tilting section connects oil storage section is greater than the port diameter of tilting section connecting cylinder section, be equipped in the middle part of oil storage section it is several around
The segment groove of guide body central axis circle distribution, and each segment bottom portion of groove is connected to by pipeline, is set in segment groove
There is ball, is equipped with the stop collar for preventing ball from skidding off out of segment groove, stop collar and segment groove ends at segment groove port
Mouth is internal to be fixedly connected.
The hollow shaft inner hole surface of guide ontology is equipped with wearing layer.
Wearing layer in the hollow shaft inner hole surface of guide ontology is potassium steel layer.
Guide ontology both ends are respectively provided with a nylon cushion block.
Nylon cushion block is bolted on guide ontology both ends.
The beneficial effects of the utility model are: the horn mouth conical section design of the utility model is reduced in guide ontology
The nylon cushion block of the extruding force of pin, guide ontology both ends can be squeezed with absorbing external, can be stored in oil storage section and segment groove
Lubricating oil, ball reduce the frictional resistance sold in guide ontology and guide ontology, improve the working efficiency of excavator, extend
The service life of excavator.

It is described in detail below with reference to the embodiments of the present invention referring to attached drawing.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1, 2, a kind of crawler of excavator guide, including guide ontology 1, guide ontology 1 are hollow shaft structure, pin
The hollow shaft inner hole surface of ontology 1 is covered using the geometric center of guide ontology 1 as basic point bilateral symmetry, in the hollow shaft of guide ontology 1
Hole Middle face is oil storage section 2, and 2 both ends of oil storage section are connected with tilting section 3, and tilting section 3 is connected with cylindrical section 5 far from one end of oil storage section 2,
Cylindrical section 5 is connected with horn mouth conical section 4 far from one end of tilting section 3, and the bevel angle of 4 inner hole surface of horn mouth conical section is not more than
5 °, horn mouth conical section 4 is greater than the diameter of the other end close to the diameter of one end of 1 port of guide ontology, and tilting section 3 connects oil storage
The port diameter of section 2 is greater than the port diameter of 3 connecting cylinder section 5 of tilting section, is equipped in the middle part of oil storage section 2 several around guide ontology 1
The segment groove 6 of central axis circle distribution, and each 6 bottom of segment groove is connected to by pipeline, and ball is equipped in segment groove 6
7, the stop collar 8 for preventing ball 7 from skidding off out of segment groove 6, stop collar 8 and 6 end of segment groove are equipped at 6 port of segment groove
Mouth is internal to be fixedly connected.
The hollow shaft inner hole surface of guide ontology 1 is equipped with wearing layer.
