Abstract
The utility model relates to a gear, in particular to a gear with a changeable inner ring. The gear comprises a gear ring, gear teeth, a gear hub hole and an annular groove, wherein the gear teeth are formed in the outer edge of the gear ring, the gear hub hole is formed in the center of the gear ring, the annular groove is formed between the gear ring and the gear hub hole, the gear hub hole is formed in the inner ring which is fixed in the gear ring, a clamping block is arranged on the inner ring, a clamping groove is formed in the gear ring, and the inner ring is inserted into the clamping groove through the clamping block and fixedly connected with the gear ring. According to the gear, the maintaining effect can be realized by directly changing the inner ring instead of changing the whole gear after the hub hole is damaged, the cost is saved, and the effect is improved.
Description
Technical field
The utility model relates to a kind of gear, the interchangeable gear of especially a kind of inner ring.
Background technique
Be applied at present the turbine and worm transmission device, gear especially for the locomotive controlling device, be directly to be placed on bearing pin by gear nave boss hole, may move in wheel bore because of axle easily makes wheel bore damage and must change whole gear, easily causes larger economic loss.
The model utility content
For the wheel bore that overcomes existing gear holds flimsy deficiency, the utility model provides a kind of inner ring interchangeable gear.
The technological scheme that its technical problem that solves the utility model adopts is: the interchangeable gear of a kind of inner ring, comprise gear ring, teeth, gear hub hole and circular groove, the gear ring outer is provided with teeth, gear ring center is provided with the gear hub hole, be provided with circular groove between gear ring and gear hub hole, inner ring is provided with the gear hub hole, and inner ring is fixed in gear ring.
According to another embodiment of the present utility model, comprise that further inner ring is provided with fixture block, be provided with draw-in groove in gear ring, inner ring inserts in draw-in groove by fixture block and realizes and being fixedly connected with of gear ring.
The beneficial effects of the utility model are that this gear can directly reach the effect of maintenance and needn't change whole gear by changing inner ring after wheel bore damage, and has saved cost, has improved effect.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the interchangeable gear of a kind of inner ring;
1. gear rings in figure, 2. teeth, 3. gear hub hole, 4. circular groove, 5. inner ring, 6. fixture block, 7. draw-in groove.
Embodiment
It is the structural representation of the interchangeable gear of a kind of inner ring as Fig. 1, the interchangeable gear of a kind of inner ring, comprise gear ring 1, teeth 2, gear hub hole 3 and circular groove 4, gear ring 1 outer is provided with teeth 2, and gear ring 1 center is provided with gear hub hole 3, be provided with circular groove 4 between gear ring 1 and gear hub hole 3, inner ring 5 is provided with gear hub hole 3, and inner ring 5 is fixed in gear ring 1, and inner ring 5 is provided with fixture block 6, be provided with draw-in groove 7 in gear ring 5, inner ring 5 inserts being fixedly connected with of the interior realizations of draw-in groove 7 and gear ring 5 by fixture block 6.
After gear hub hole 3 is damaged by axle, only need to be inner ring 5 from the interior taking-up of gear ring 1, and then new inner ring 5 is loaded onto gear ring 1 get final product, only need to insert draw-in groove 7 to the fixture block of inner ring 5 during dress inner ring 5 and just complete connection procedure, this gear can directly reach the effect of maintenance and needn't change whole gear by changing inner ring after wheel bore damage, save cost, improved effect.
