Abstract
The utility model provides an iron core wheel with changeable cover tyre. The iron core wheel is characterized in that an iron core hub is provided with a cover tyre, the iron core hub and the cover tyre are provided with a clamping ring, and a connector in turn passes through the clamping ring and the iron core hub to cling the clamping ring to the iron core hub and the cover tyre. When worn, the cover tyre can be replaced by a new cover tyre. The utility model has simple structure, long service life, and strong versatility.
Description
The utility model relates to a kind of iron core wheel, particularly be a kind of iron core wheel of interchangeable cover tire.
Known iron core wheel is made up of the rubbery cover tyre that the iron core wheel hub reaches and the iron core wheel hub is in aggregates.This tire is in use because of the weight friction, collision and the rubbery cover tyre easily aging a variety of causes that waits that exposes to the sun and rain, cover tire is very fragile, because of cover tire and iron core wheel hub are an integral body, so cover tire scrap and whole iron core taken turns all scrap, service life weak point.
In view of above reason, the purpose of this utility model is in order to provide a kind of cover tire interchangeable, the iron core wheel of the interchangeable cover tire of long service life.
The utility model comprises the iron core wheel hub, it is characterized in that on the iron core wheel hub cover tire being housed, on iron core wheel hub and cover tire, clamping ring is arranged, connector passes clamping ring successively and the iron core wheel hub is close to (referring to Fig. 1) on iron core wheel hub and the cover tire with clamping ring, detachably, can take off the cover tire that renews in addition after the cover tire wearing and tearing are bad, and prolong the service life of whole iron core wheel hub.
Two antifriction-bearing boxs are housed in the above-mentioned axle hole, at two roller bearing shops concentric inner shield ring, outer back-up ring are housed, on at least one end face of axle hole, dustproof oil cap (referring to Fig. 1) is housed by connector, both dustproof, can stop bearing in its axle hole again when stressed rolling about play.
All dustproof oil cap (referring to Fig. 1) is housed on the above-mentioned axle hole both ends of the surface by connector, be convenient to load and unload unpick and wash, tenure of use of oil sealing, prolongation duplex bearing.
The detachable back-up ring that unloads of the other end of above-mentioned axle hole, the end face that the dismounting back-up ring stretches out axle hole exceeds axle hole end face (referring to Fig. 2), and iron core wheel hub intensity height is attractive in appearance, dismantles more convenient.
Compare with existing iron core wheel hub, the utlity model has simple in structure, detachable, cover tire is interchangeable, advantages such as highly versatile, long service life.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation
Fig. 2 is axle hole and dismounting back-up ring assembly drowing
Embodiment 1:
As can be seen from Figure 1, wear-resisting pressure-proof rubbery cover tyre 1 is sleeved on the iron core wheel hub 2, be provided with caulking groove 3,4 on the two sides of rubbery cover tyre 1 and iron core wheel hub 2, the two ends of the clamping ring 5,6 of steel disc compression moulding are divided in the caulking groove 3,4 on rubbery cover tyre 1 and iron core wheel hub 2 two sides, and connector---clamping screw 7 passes the hole on clamping ring 5,6 and the iron core wheel hub 2 successively and with tight pinning of nut 8 two ends of clamping ring 5,6 is close in the caulking groove 3,4.Two dish single-row centripetal antifriction-bearing boxs 10,11 are housed in axle hole 9.10,11 of single-row centripetal antifriction-bearing boxs are equipped with concentric inner shield ring 12, outer back-up ring 13.The thickness of inside and outside back-up ring equates. Dustproof oil cap 14,15 is divided on the two ends of axle hole and with screw rod 16 tightenings.
Embodiment 2:
