Abstract
The utility model relates to a gear, in particular to a radiating type gear. The gear comprises a gear ring, gear teeth, a gear hub hole and an annular groove, wherein 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; a protective layer is fixed on the outer wall of the gear ring and is a ceramic sheet. The gear can well control the high temperature produced during operation, the service life of the gear is prolonged, the driving safety is guaranteed, the cost is saved, and the efficacy is improved.
Description
Technical field
The utility model relates to a kind of gear, especially a kind of heat radiating type gear.
Background technique
Be applied at present the turbine and worm transmission device, gear especially for the locomotive controlling device, directly to be placed on bearing pin by gear nave boss hole, may easily produce because of gear high temperature when operating, institute is so that gear generation deformation, thereby make gear generation mechanical failure, shorten the working life of gear.
The model utility content
In order to overcome the deficiency of existing gear poor radiation, the utility model provides a kind of heat radiating type gear.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of heat radiating type gear, 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, be fixed with protective coating on the gear ring outer wall.
According to another embodiment of the present utility model, comprise that further protective coating is ceramic plate.
The beneficial effects of the utility model are, the high temperature that this gear produces in the time of can well controlling run has extended working life of gear, has guaranteed traffic safety, 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 a kind of structural representation of heat radiating type gear;
1. gear rings in figure, 2. teeth, 3. gear hub hole, 4. circular groove, 5. protective coating.
Embodiment
It is a kind of structural representation of heat radiating type gear as Fig. 1, a kind of heat radiating 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, be provided with circular groove 4 between gear ring 1 and gear hub hole 3, be fixed with protective coating 5 on gear ring 1 outer wall, protective coating 5 is ceramic plate.
Be fixed with the protective coating 5 of one deck ceramic plate system on gear ring 1 surface of gear, use ceramic plate can well absorb and distribute the heat of gear, and use ceramic plate, can play good antisepsis, avoid gear to be corroded by foreign object, the high temperature that this gear produces in the time of can well controlling run, extended the working life of gear, guarantee traffic safety, saved cost, improved effect.
