Abstract
The utility model relates to a gear, in particular to a firm gear. The gear comprises a gear ring, gear teeth, a gear hub hole and an annular groove. The gear teeth are arranged on 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, reinforcing cylinders are arranged on the two sides of the annular groove, the gear hub hole and penetrating holes of the reinforcing cylinders are consistent in opening and are communicated, reinforcing ribs are arranged between the reinforcing cylinders and the annular groove, the reinforcing cylinders are ceramic cylinders, and rubber layers are arranged on the inner walls of the reinforcing cylinders. It is guaranteed that the gear cannot sway during rotation, the service life of the gear is prolonged, the cost is saved, and the effect is improved.
Description
Technical field
The utility model relates to a kind of gear, especially steady type gear.
Background technique
Be applied at present turbine and worm transmission device, gear especially for locomotive controlling device, directly to be placed on bearing pin by gear nave boss hole, but because gear both sides do not have reinforcing device., so may there is left and right skew when rotating, thereby have influence on the stability of gear operation, and can shorten the working life of gear.
Model utility content
The deficiency that may be offset when overcoming existing gear operation, the utility model provides steady type gear.
The utility model solves the technological scheme that its technical problem adopts: steady type gear, comprise gear ring, teeth, gear hub hole and circular groove, gear ring outer is provided with teeth, gear ring center is provided with gear hub hole, between gear ring and gear hub hole, be provided with circular groove, circular groove both sides are provided with and reinforce cylinder, and gear hub hole is consistent with the perforation openings of reinforcing cylinder and be communicated with, reinforce tin and circular groove between be provided with stiffening rib.
According to another embodiment of the present utility model, further comprise and reinforce cylinder for ceramic cylinder.
According to another embodiment of the present utility model, further comprise that reinforcing cylinder inwall is provided with rubber layer.
The beneficial effects of the utility model are that this gear can keep it when rotating, can not rock, and has extended the working life of gear, has saved cost, has improved effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the plan view of steady type gear;
Fig. 2 is the right elevation of steady type gear;
1. gear rings in figure, 2. teeth, 3. gear hub hole, 4. circular groove, 5. reinforcing cylinder, 6. stiffening rib, 7. rubber layer.
Embodiment
If Fig. 1 is the plan view of steady type gear, Fig. 2 is the right elevation of steady type gear, steady type gear, comprise gear ring 1, teeth 2, gear hub hole 3 and circular groove 4, gear ring 1 outer is provided with teeth 2, gear ring 1 center is provided with gear hub hole 3, between gear ring 1 and gear hub hole 3, be provided with circular groove 4, circular groove 4 both sides are provided with and reinforce cylinder 5, gear hub hole 3 is consistent with the perforation openings of reinforcing cylinder 5 and be communicated with, reinforce between cylinder 5 and circular groove 4 and be provided with stiffening rib 6, reinforcing cylinder 5 is ceramic cylinder, reinforces cylinder 5 inwalls and is provided with rubber layer 7.
Bearing pin can pass reinforcing cylinder 5 and the gear hub hole 3 of circular groove 4 both sides, and reinforcing like this cylinder 5 just can increase the connection area of gear and bearing pin, thereby has increased stability, and stiffening rib 6 can increase the join strength of reinforcing cylinder 5 and gear.Use the reinforcing cylinder 5 of pottery system can increase its corrosion resistance and help heat radiation, the rubber layer 7 of reinforcing in cylinder 5 is directly not contact with bearing pin so that reinforce cylinder 5, thereby when increasing working life, be its increase frictional force, make bearing pin more firm with being connected of gear, this gear can keep it when rotating, can not rock, extend the working life of gear, saved cost, improved effect.Effect.
