Abstract
The invention relates to an arc bevel gear comprising a gear body; a plurality of arc teeth are arranged on the gear body; the gear body is provided with a platform; the arc tooth is provided with a chamfer; an axial center of the gear body is provided with a center hole; the side wall of the center hole is provided with a plurality of keyways; the gear body is coated with a wearing layer. The arc bevel gear is simple in structure, convenient in usage, loses less energy in a transmission process, is good in energy saving effect, and tooth root portion is hard to damage, thus prolonging gear life, and reducing production cost.
Description
Technical field
The present invention relates to a kind of bevel gear.
Background technique
Bevel gear it mainly design based on the equivalent life of large small gear in fact, two effects below are mainly carried out when carrying out Intensity Design, one is flexural strength, one is contact fatigue strength, large pinion gear teeth number is different, so different with time revolution, therefore requiring the intensity of the single tooth of steamboat to be higher than bull wheel, can to realize the large steamboat life-span close.In present gear structure, its tooth is connected respectively at the bottom of tooth top and tooth by two involutes and forms, all plane structure at the bottom of tooth top and tooth, the linkage structure of plane and curved surface has corner angle, power-assisted is brought to gear transmission, and excessive resistance easily makes tooth from tooth fracture of root, effective transmission cannot be realized and affect product working life, be arranged so that the energy lost in transmission process is more due to plane structure, energy-saving effect is poor, tooth root portion easily occurs that stress point causes damage, reduces the working life of gear, increases cost of production.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of bevel gear increased the service life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bevel gear, there is gear, described gear is provided with some arc teeth, gear is provided with boss, arc teeth are provided with chamfering, gear axial centre place is provided with center hole, the sidewall of center hole offers some keyways, gear is coated with wearing layer.
Further, the quantity of described arc teeth is 15-30.
Further, described center hole tapping is provided with chamfering.
Further, described gear and arc teeth are formed in one structure.
Further, the surface of described gear and arc teeth is through stiffened heat treatment.
Further, the quantity of described keyway is 2-6.
The invention has the beneficial effects as follows: structure of the present invention is simple, easy to use, using, the energy lost in transmission process is less, good energy-conserving effect, and damaging not easily appears in tooth root portion, extends the working life of gear, reduces cost of production.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. gear in figure, 2. arc teeth, 3. boss, 4. chamfering, 5. center hole, 6. keyway, 7. wearing layer.
Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of bevel gear as shown in Figure 1, there is gear 1, gear 1 is provided with some arc teeth 2, gear 1 is provided with boss 3, arc teeth 2 are provided with chamfering 4, gear 1 axial centre place is provided with center hole 5, the sidewall of center hole 5 offers some keyways 6, the quantity of keyway 6 is 2-6, keyway 6 well can ensure the positioning precision of bevel gear, not easily produce skew, cause error, gear 1 is coated with wearing layer 7, the surface of gear 1 and arc teeth 2 is through stiffened heat treatment, damaging not easily appears in tooth root portion, extend the working life of gear, reduce cost of production, the quantity of arc teeth 2 is 15-30, easy to use, using, the energy lost in transmission process is less, good energy-conserving effect, center hole 5 tapping is provided with chamfering, chamfering is convenient to the installation of gear, increase work efficiency, gear 1 and arc teeth 2 are formed in one structure.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
