Description
Technical field
The utility model is related to the technical field of excavating equipment, specially a kind of Wheel structure of support sprocket wheel.
Background technology
Support sprocket wheel is important spare part in digging machine walking mechanism, bears that load is smaller, and there is certain guiding to make
With.The wheel body of existing support sprocket wheel is separately formed both sides wheel body by forging, then by being welded after both sides theory is inscribed centering
Molding, the wheel body inner groovy after welding are the face that smoothly transits, and after being packed into belt or aluminium strip, width easily occurs for belt or crawler belt
Direction displacement influences whole manipulation so that excavator will produce weak vibrations.
Invention content
In view of the above-mentioned problems, the utility model provides a kind of Wheel structure of support sprocket wheel, ensure internal flush-mounted in wheel
The stabilization of the belt of groove or the width direction of crawler belt ensures the steady running of excavator.
A kind of Wheel structure of support sprocket wheel, it is characterised in that：It includes inside wheel body, outside wheel body, the outside wheel body,
Collar member is docked and be set in the opposite end face in centre of inside wheel body, the both sides of the collar member respectively with the outside wheel body,
Be welded to connect between the wheel body of inside, the outer circumferential surface spirogyrate of the collar member in pairs in positioning protrusion, the centering convex
It rises for the positioning of the width direction of belt or crawler belt.
It is further characterized by：
The outer ring surface of the opposite end face of the outside wheel body is provided with the first indent location structure, the phase of the inside wheel body
The outer ring surface of end face is provided with the second indent location structure, the first indent location structure, the second indent location structure are spelled
Concave ring in complete is formed after conjunction, the periphery of the interior concave ring is set with the collar member；
The width of the interior concave ring is more than the width of the collar member；
The center hole part of the outside wheel body is provided with outside positioning bearer ring face, the central part of the inside wheel body
It is provided with inside positioning bearer ring face, oil sealing positioning.
After the structure of the utility model, since the opposite end face in the centre of outside wheel body, inside wheel body is docked and is set with
There are collar member, the both sides of collar member to be welded to connect between the outside wheel body, inside wheel body respectively so that wheel body is spliced group
Dress is formed, and the outer ring surface spirogyrate of collar member in pairs in positioning protrusion, the centering positioning protrusion is for belt or crawler belt
Width direction positions；And then it ensures the stabilization flush-mounted in the belt of wheel body inner groovy or the width direction of crawler belt, ensures to excavate
The steady running of machine.
