Detailed description of main elements：Luntai 1, dormant bolt 2, driving wheel ontology 3, annular flange 31, wheel disc 32, annular convex shoulder
33；Annular tooth wheel rim 11 takes turns teeth 12,
Specific embodiment：
Embodiment：
Referring to shown in each figure, a kind of opencut large excavator driving wheel of the utility model, including driving wheel ontology 3,
Luntai 1, the driving wheel ontology 3 are split type connection structure with the Luntai 1, and the driving wheel ontology 3 is round along outer rim middle part
Monday encloses the integrally formed annular flange 31 for being set as uniform thickness；31 thickness of annular flange is less than the driving wheel ontology 3
32 thickness of wheel disc so that 31 two bottom sides of annular flange form the symmetrical annular convex shoulder 33 expanded outward；The Luntai 1
Two symmetrical annular tooth wheel rims 11 are set as, the annular tooth wheel rim 11 is circumferentially uniformly arranged multiple wheel teeth 12, described
Annular tooth wheel rim 11 is symmetrically installed in 31 both sides of annular flange, 11 inner ring of annular tooth wheel rim and the annular convex shoulder 33
It matches and the fitting of 31 side of the annular flange, the annular tooth wheel rim 11 takes turns 12 lower position of teeth and the ring described
Shape flange 31 is fixed by dormant bolt 2, and the annular flange 31 and the outer diameter of 11 contact surface of annular tooth wheel rim etc. are big, in axis
The wheel teeth 12 and 31 edge junction of annular flange into section；The annular tooth wheel rim 11 and the driving wheel ontology
3 are combined into the driving wheel.
Outer rim after the annular tooth wheel rim 11 is combined with the driving wheel ontology 3 presses former working size setting.
See Fig. 2-1, state 2 diameter d of the dormant bolt and 11 outer diameter Φ of annular tooth wheel rim and compare d:Φ is 1:20—1:30；Institute
State the ratio h of the poor h of 11 internal-and external diameter of annular tooth wheel rim and the outer diameter Φ of the annular tooth wheel rim 11:Φ is 1；6--1:9.
11 outer diameter Φ of annular tooth wheel rim described in the 2 diameter d of dormant bolt compares d:Φ is 1:24—1:26；The annular tooth
The ratio h of the poor h of 11 internal-and external diameter of wheel rim and the outer diameter Φ of the annular tooth wheel rim 11:Φ is 1；7.3--1:7.7.
The utility model is made of Luntai 1, dormant bolt 2, driving wheel ontology 3, and the utility model is by original driving wheel
Split combination structure is changed to, the working position for combining rear main wheel keeps former working size.Luntai 1 is fixed on attachment bolt
On ontology 3, once Luntai wear and rupture can be replaced product at any time during the work time, ontology does not have to replace, ontology production cost
Height, the production cost ratio that Luntai accounts for entire driving wheel is low, and the use cost with respect to driving wheel reduces 40% -50%, Luntai
Intensity is high, and driving wheel is mounted on track frame, and active Luntai contacts driving excavator walking with caterpillar chain.
The 2 diameter d of the dormant bolt and 11 outer diameter Φ of annular tooth wheel rim compares d:Φ is 1:20—1:30；The annular
The ratio h of the poor h of 11 internal-and external diameter of gear ring and the outer diameter Φ of the annular tooth wheel rim 11:Φ is 1；6--1:9.It is preferred that the countersunk head
11 outer diameter Φ of annular tooth wheel rim compares d described in 2 diameter d of bolt:Φ is 1:24—1:26；The difference of 11 internal-and external diameter of annular tooth wheel rim
The ratio h of h and the outer diameter Φ of the annular tooth wheel rim 11:Φ is 1；7.3--1:7.7.The 2 diameter d of dormant bolt and the ring
11 outer diameter Φ ratios of shape gear ring are less than required ratio, then bolt easily occurs to be cut；If more than required ratio, then influence to take turns
The intensity of platform 1 makes Luntai fragile.In required proportional region, it is ensured that the driving wheel normal use prolongs the service life.
If the ratio of the poor h of 11 internal-and external diameter of annular tooth wheel rim and the outer diameter Φ of annular tooth wheel rim 11 are less than required ratio,
It the easily fracture damage of Luntai 1 and can not install；If more than required ratio, then increase cost, and change former driving wheel
Shape.
