Abstract
The utility model discloses a gear with high transmission efficiency. The gear with the high transmission efficiency comprises a gear body, outer teeth are arranged on the outer side of the gear body, the outer teeth are spirally distributed on the outer side of the gear body and the whole gear body is completely covered with the outer teeth, the outer teeth are tapered teeth and are 60 in number, the tip diameter of the gear body is 30mm, the root diameter of the gear body is 32mm, a shaft hole is formed in the center of the gear body, and a plurality of through holes are formed in the periphery of the surface of the gear body. The gear with the high transmission efficiency is simplified to be in single-stage gear transmission, and therefore the transmission efficiency is high, investment cost is lowered, and operation cost is reduced.
Description
Technical field
The utility model relates to the high gear of a kind of transmission efficiency.
Background technique
Having many uses of gear is the strength member in the various machinery, all will use various gears as the wrist-watch used in lathe, aircraft, steamer and the 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 standard cylinder gear again.Parameters such as the formation of relevant gear involute, modulus, pressure angle will be introduced in relevant course.Here mainly introduce the processing method of spur gear wheel, the processing method of the form of gear tooth has two kinds.A kind of is forming method, utilizes the method that cuts out profile of tooth with the profiling cutter that is conformed to fully by the gear cutting machine slot form exactly, as mill teeth; Another kind is generating method, and it is to utilize being meshing with each other motion of gear cutting tool and driven gear and cut out the processing method of profile of tooth, as gear hobbing and gear shaping (demonstrating with hobboing cutter and slotting tool).Introduce the method that adds work gear with milling machine below.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.O.004～100 millimeter modern gear technique reaches: module; Gear diameter is by 1 millimeter～150 meters; Transmitted power can reach 100,000 kilowatts; Change 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 Aristotle of Ancient Greece man has just set forth the problem with bronze or cast iron gear transferring rotational motion in " mechanical problem ".Ancient Chinese is for having used a whole set of train in the vehicle pointing to the south of model utility.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 gear structure comparatively compact to a certain extent, and can realize bigger single gear velocity ratio, but compacter at the needs gear structure, when single gear rotation ratio was bigger, the gear of three teeth just was difficult to satisfy.
The model utility content
The purpose of this utility model is to have the gear that provides a kind of transmission efficiency high the single gear of being reduced to transmission, thereby make the rotational efficienty height, reduces cost of investment, has reduced operating cost.
The technical solution of the utility model 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 awl 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, is provided with several through holes around the described gear body surface.
In preferred embodiment of the utility model, described gear body is quenched to refine by metallic dust and is formed.
In preferred embodiment of the utility model, the number of described through hole is 4.
The high gear of a kind of transmission efficiency of the present utility model has the single gear of being reduced to transmission, thereby makes the rotational efficienty height, reduces cost of investment, has reduced operating cost.
Description of drawings
Accompanying drawing 1 is the perspective view of the high gear of the utility model transmission efficiency one preferred embodiment.
The mark of each parts is as follows in the accompanying drawing: 1, gear body, 2, top circle, 3, root circle.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, Fig. 1 is the high gear of a kind of transmission efficiency of the utility model, 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 awl 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 described gear body is provided with several through holes around 1 surface.
Further specify, 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 technology after the carburizing.Owing to contain the element that chromium and molybdenum etc. form carbide in chromium manganese molybdenum steel and the Cr-Mo steel, in carburizing process, will impel the tooth surface Kohlenstoffgehalt to increase, a large amount of carbide appear in the carburized case tissue easily, 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 excessive carbide.The steel smelting process stabilizing, hardenability band is narrower and be easy to control, and it is little to have Heat Treatment Distortion, and infiltration layer has good, stable hardenability, and the surface behind the carburizing and quenching and centre hardness all can satisfy technical requirements preferably; Fatigue behaviour is good, relatively is fit to fine module gear in the automobile.Take all factors into consideration the service condition of gear, both guaranteed the fatigue life of gear, reduce the Heat Treatment Distortion of gear again, the utility model provides a kind of transmission efficiency high gear, has the single gear of being reduced to transmission, thereby makes the rotational efficienty height, reduce cost of investment, reduced operating cost.
Embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
