Abstract
The invention relates to a straight spur gear with anti-bending and impact resistance performances; the straight spur gear comprises a gear body; the center of the gear body is provided with a center hole; the inner wall of the center hole is uniformly provided with a plurality of keyways; the gear body is provided with a groove; the groove is uniformly provided with a plurality of holes in the periphery direction of the groove; the outer circumference of the gear body is uniformly provided with teeth. The straight spur gear is simple in structure, convenient in usage, has good impact resistance performance and bending-resistant performance, so the teeth cannot be broken under variable load and shock load; the tooth surface cannot have pitting, gumming, wearing and plastic deformation, and gear precision level and surface roughness can be well ensured; the straight spur gear can improve work efficiency, reduces cost, and saves resources.
Description
Technical field
The present invention relates to a kind of counter-bending and straight toothed spur gear that is impact resistance of having.
Background technique
Along with China's industrial expansion, gear is most widely used a kind of mechanical transmission part in modern mechanical, and its structural design changes along with the needs of industry.In the continuous progress of science and technology, produce all towards automation, specialization and future development quantitatively, this just requires that the production of enterprise reduces the production intensity of workman and improves the manufacturing efficiency of workman on the basis of embodying hommization, reduces the cost of production of enterprise.Require that lower gear part embodies all the more its application and market prospects widely this, after particularly combining with microelectronic, computer technology in recent years, gear part is made to enter a new developing stage, most important parts at gear component, because of the increase of demand, producing and also step into quantitatively and automation, for adapting to machinery to the requirement of Gear Processing, also needing constantly to upgrade and improve to the expansion of Gear Processing requirement and technical field.
Cylindrical gears is the important a kind of gear-type in mechanical gear, a kind of gear pattern the most common especially, and cylindrical gears, according to the direction of the gear teeth, can be divided into straight toothed spur gear, helical gear and herringbone tooth cylindrical gears.Cylindrical gears application is very general, such as: retarder etc.The gear of the present use in use flank of tooth can produce spot corrosion, gummed and wearing and tearing and plastic deformation, simultaneously the flexural strength of the flank of tooth and tough poor, there is broken teeth next time in varying load and impulsive load, and grade of accuracy and the surface roughness of gear cannot be ensured.
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 and has counter-bending and straight toothed spur gear that is impact resistance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of have counter-bending and straight toothed spur gear that is impact resistance, there is gear, the center position of described gear offers center hole, the inwall of center hole is evenly provided with some keyways, gear offers groove, groove along the circumferential direction evenly offers some circular holes, the excircle of gear is evenly provided with teeth.
Further, described gear adopts No. 45 Steel materials to make.
Further, the surface of described gear through normalized treatment, surface hardness HB=200.
Further, the quantity of described keyway is 2-6.
Further, the quantity of described circular hole is 5-10.
Further, the quantity of described teeth is 15-30.
The invention has the beneficial effects as follows: structure of the present invention is simple, easy to use, there is good impact resistance and bending resistance, broken teeth is there is next time in varying load and impulsive load, the flank of tooth can not produce spot corrosion, gummed and wearing and tearing and plastic deformation, and can ensure grade of accuracy and the surface roughness of gear very well, increases work efficiency, reduce costs, economize on resources.
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, 2. center hole, 3. keyway, 4. groove, 5. circular hole, 6. teeth in figure.
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.
As shown in Figure 1 a kind of has counter-bending and straight toothed spur gear that is impact resistance, there is gear, the center position of gear 1 offers center hole 2, the inwall of center hole 2 is evenly provided with some keyways 3, gear 1 offers groove 4, groove 4 along the circumferential direction evenly offers some circular holes 5, the excircle of gear 1 is evenly provided with teeth 6, gear 1 adopts No. 45 Steel materials to make, the surface of gear 1 is through normalized treatment, surface hardness HB=200, there is good impact resistance and bending resistance, broken teeth is there is next time in varying load and impulsive load, the flank of tooth can not produce spot corrosion, glue together and wear and tear and plastic deformation, the quantity of keyway 3 is 2-6, the quantity of circular hole 5 is 5-10, economize on resources, the quantity of teeth 6 is 15-30, structure is simple, easy to use, and grade of accuracy and the surface roughness of gear can be ensured very well, increase work efficiency, reduce costs.
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.
