Abstract
The invention discloses a high transmission efficiency gear which comprises a gear main body, wherein outer teeth are arranged and spirally distributed on the outer side of the gear main body, and cover the whole gear main body. The outer teeth are 60 conical teeth. The tooth tip diameter of the gear main body is 30 millimeters, the tooth root diameter is 32 millimeters, a shaft hole is formed in the center of the gear main body, and a plurality of through holes are formed in the periphery of the surface of the gear main body. The high transmission efficiency gear has the advantages that the transmission is simplified to be a single-stage gear transmission, the transmission efficiency is enabled to be high, investment cost is lowered, and operation cost is reduced.
Description
Technical field
The present invention relates to the high gear of a kind of transmission efficiency.
Background technique
Having many uses of gear is the strength member in various machinery, all will use various gears as the wrist-watch used in lathe, aircraft, steamer and daily life, electric fan etc.The kind of gear is a lot, and spur gear wheel, cylindric spiral gear, spiral gear, straight toothed bevel gear, spiral bevel gear, worm gear etc. are arranged.Wherein use morely, also better simply is spur gear wheel, claims again standard cylinder gear.The parameters such as the formation of relevant Involute gear, modulus, pressure angle will be introduced in relevant course.Here the processing method of article spur gear wheel, the processing method of the form of gear tooth has two kinds.A kind of is forming method, utilizes exactly the method that cuts out profile of tooth with the profiling cutter that is conformed to fully by the gear cutting machine slot form, as mill teeth; Another kind is generating method, and it is to utilize the intermeshing motion of gear cutting tool and driven gear and the processing method that cuts out profile of tooth, as gear hobbing and gear shaping (demonstrating with hobboing cutter and slotting tool).The below introduces the method with the milling machine machining gears.Gear is the intermeshing mechanical parts that tooth is arranged of energy, and its application in mechanical transmission and whole mechanical field is extremely extensive.The Modern Gear technology reaches: O.004～100 millimeters of modules; Gear diameter is by 1 millimeter～150 meters; Transmitted power can reach 100,000 kilowatts; Turn scooter hundreds of thousands rev/min; The highest peripheral velocity reaches 300 meter per seconds.The application of gear in transmission occurred very early.In first three more than hundred years Christian era, the Ancient Greece Aristotle of man has just set forth the problem with bronze or cast iron gear transferring rotational motion in " mechanical problem ".Used a whole set of train in the vehicle pointing to the south of ancient Chinese invention.But, the gear minimum teeth number that China produces at present is 3, the gear of 3 teeth is applied in the gear rotation, can make to a certain extent gear structure comparatively compact, and can realize larger single gear transmission ratio, but compacter at the needs gear structure, when single gear rotation ratio was larger, the gear of three teeth just was difficult to satisfy.
Summary of the invention
The object of the present invention is to provide the high gear of a kind of transmission efficiency, have the single gear transmission of being reduced to, thereby make rotational efficienty high, reduce cost of investment, reduced operating cost.
Technological scheme of the present invention is: the gear that a kind of transmission efficiency is high, the gear that described transmission efficiency is high comprises gear body, the described gear body outside is provided with external tooth, described external tooth spiral substep is in the gear body outside and be covered with whole gear body, the described external tooth number of teeth is 60 cone teeth, and the tip diameter of described gear body is 30 millimeters, and root diameter is 32 millimeters, described gear body center is provided with axis hole, and the surperficial surrounding of described gear body is provided with several through holes.
In a preferred embodiment of the present invention, described gear body is quenched to refine by metallic dust and is formed.
In a preferred embodiment of the present invention, the number of described through hole is 4.
The high gear of a kind of transmission efficiency of the present invention has the single gear transmission of being reduced to, thereby makes rotational efficienty high, reduces cost of investment, has reduced operating cost.
Description of drawings
Accompanying drawing 1 is the perspective view of high gear one preferred embodiment of transmission efficiency of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, gear body, 2, top circle, 3, root circle.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
See also Fig. 1, Fig. 1 is the high gear of a kind of transmission efficiency of the present invention, the gear that described transmission efficiency is high comprises gear body 1, described gear body 1 outside is provided with external tooth, and described external tooth spiral substep is in gear body 1 outside and be covered with whole gear body 1, and the described external tooth number of teeth is 60 cone teeth, top circle 2 diameters of described gear body 1 are 30 millimeters, root circle 3 diameters are 32 millimeters, and described gear body 1 center is provided with axis hole, and the surperficial surrounding of described gear body 1 is provided with several through holes.
Further illustrate, described gear body is quenched to refine by metallic dust and is formed, and the number of described through hole is 4, and described metallic dust comprises chromium, manganese, molybdenum and steel.Described metallic dust can adopt direct quenching technique after carburizing.Due to the element that contains the formation carbide such as chromium and molybdenum in chromium manganese molybdenum steel and Cr-Mo steel, will impel the tooth surface Kohlenstoffgehalt to increase in carburizing process, a large amount of carbide easily appear in microstructure, make the carburized case mis-behave.Therefore, when gear adopts chromium manganese molybdenum steel and Cr-Mo steel carburizing, should adopt weak carburizing atmosphere, to prevent from forming the excess carbon compound.The steel smelting process stabilizing, hardenability band is narrower and be easy to control, has Heat Treatment Distortion little, and infiltration layer has good, stable hardenability, and the surface after carburizing and quenching and centre hardness all can satisfy technical requirements preferably; Fatigue behaviour is good, relatively is fit to fine module gear in automobile.Consider the service condition of gear, both guaranteed the fatigue life of gear, reduce again the Heat Treatment Distortion of gear, the invention provides the high gear of a kind of transmission efficiency, have the single gear transmission of being reduced to, thereby make rotational efficienty high, reduce cost of investment, reduced operating cost.
The specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and variation or the replacement that can expect without creative work are within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
