Abstract
The invention discloses a gear wheel capable of rotating smoothly. The gear wheel capable of rotating smoothly comprises a drive gear wheel and a driven gear wheel, wherein a shaft hole is formed in the surface of the drive gear wheel, and the driven gear wheel is fixed in the shaft hole. Oblique teeth are arranged on the periphery of the drive gear wheel, conical teeth are arranged on the periphery of the driven gear wheel, a plurality of through holes are formed in the surface of the driven gear wheel, and the driven gear wheel is made of epoxy resin. The gear wheel capable of rotating smoothly is characterized in that friction is reduced, service life is prolonged, revolution number of the gear wheel is improved, and the gear wheel rotates smoothly.
Description
Technical field
The present invention relates to a kind of gear of stability of rotation.
Background technology
Having many uses for gear, is the strength member in various plant equipment, and the wrist-watch, electric fan in such as lathe, aircraft, steamer and daily life will use various gears.The species of gear is a lot, there is spur gear wheel, cylindric spiral gear, helical gear, straight bevel gear, spiral bevel gear, worm gear etc..Wherein using more, also better simply is spur gear wheel, also known as standard cylinder gear.It will be introduced about parameters such as the formation of Involute gear, modulus, pressure angles in relevant course.Here the processing method for mainly introducing spur gear wheel, the processing method of the form of gear tooth has two kinds.One kind is forming process, exactly utilizes the method with being cut out tooth form by the form cutter that gear cutting machine slot form is consistent completely, such as mill teeth；Another is generating, and it is the processing method moved using the intermeshing of cutter for gear wheel and driven gear and cut out tooth form, such as gear hobbing and gear shaping（Demonstrated with hobboing cutter and slotting tool）.The method that gear is processed with milling machine is described below.Gear is mutually engageable machine components with teeth, and its application in machine driving and whole mechanical field is extremely extensive.Modern Gear technology has reached：O.004~100 millimeter module；Gear diameter is by 1 millimeter~150 meters；Power is transmitted up to upper 100,000 kilowatts；Rotating speed is up to hundreds of thousands rev/min；Highest peripheral speed is up to 300 meter per seconds.Application of the gear in transmission is occurred in that very early.B.C. more than 300 years, Ancient Greece man Aristotle existed《Mechanical problem》In, the problem of just elaborating with bronze or cast iron gear transmission rotary motion.The train of the whole series has been applied in the vehicle pointing to the south of ancient Chinese invention.
In order to improve the service life of power transmission gear and reduce its size, except improving outer in terms of material, heat treatment and structure, arc toothed gear is developed.1907, British Frank Humphris delivered arc toothed earliest.Nineteen twenty-six, auspicious natives Eruest Wildhaber obtain the arc toothed helical gear patent right of normal plane.Nineteen fifty-five, the M.L.Novikov of the Soviet Union completes the Practical Research of arc toothed gear and obtains Lenin's medal.1970, Britain Rolh-Royce company project teachers R.M.Studer achieved the United States Patent (USP) of Novikov gears with double circular arc tooth profiles.This gear is increasingly paid attention to by people, and notable benefit has been played aborning.Gear is mutually engageable machine components with teeth, and its application in machine driving and whole mechanical field is extremely extensive.Modern Gear technology has reached：O.004~100 millimeter module；Gear diameter is by 1 millimeter~150 meters；Power is transmitted up to upper 100,000 kilowatts；Rotating speed is up to hundreds of thousands rev/min；Highest peripheral speed is up to 300 meter per seconds.Application of the gear in transmission is occurred in that very early.B.C. more than 300 years, Ancient Greece man Aristotle existed《Mechanical problem》In, the problem of just elaborating with bronze or cast iron gear transmission rotary motion.The train of the whole series has been applied in the vehicle pointing to the south of ancient Chinese invention.But, the gear in ancient times is manufactured with timber or cast with metal, can only transmit the gyration of between centers, it is impossible to ensure the stationarity of transmission, the bearing capacity of gear also very little.
The content of the invention
It is an object of the invention to provide a kind of gear of stability of rotation, with friction is reduced, the characteristics of service life, raising gear revolution, and pinion rotation are steady is improved.
The technical scheme is that：A kind of gear of stability of rotation, the gear of the stability of rotation includes driving gear and driven gear, and the driving gear surface is provided with axis hole, and the driven gear is fixed on the axis hole.The gabarit of the driving gear is provided with helical teeth, and the gabarit of the driven gear is provided with cone tooth, and the driven gear surface is provided with some through holes, and the driven gear is made up of epoxy resin.
In a preferred embodiment of the present invention, the epoxy resin is alicyclic based epoxy resin.
In a preferred embodiment of the present invention, the number of the through hole is 4.
A kind of gear of stability of rotation of the present invention, with friction is reduced, improves the characteristics of service life, raising gear revolution, and pinion rotation are steady.
Brief description of the drawings
Accompanying drawing 1 is the dimensional structure diagram of the preferred embodiment of gear one of stability of rotation of the present invention.
The mark of each part is as follows in accompanying drawing：1st, driving gear, 2, driven gear, 3, axis hole.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, apparent clearly defined so as to be made to protection scope of the present invention.
Referring to Fig. 1, Fig. 1 is a kind of gear of stability of rotation of the invention, the gear of the stability of rotation includes driving gear 1 and driven gear 2, and the surface of driving gear 1 is provided with axis hole 3, and the driven gear 2 is fixed on the axis hole 3.The gabarit of the driving gear 1 is provided with helical teeth, and the gabarit of the driven gear 2 is provided with cone tooth, and the surface of driven gear 2 is provided with some through holes, and the driven gear 2 is made up of epoxy resin.
Further illustrate, the epoxy resin is alicyclic based epoxy resin, and the number of the through hole is 4, described gear is due to being no longer conventional solid construction between axis hole and gear ring, the materials of single gear are greatly reduced, and effectively reduce friction, improve service life.Due to two gears, respectively there is the external tooth of independent narrower width, and two have certain rotary moveable amount between gear, so when side slide teeth is with power transmission shaft joggleword, the external tooth of the only gear is engaged with power transmission shaft, due to gear internal tooth narrower width, so gear internal tooth two ends stress is relatively uniform during work, slide teeth angle does not produce change.It is of the invention that a kind of gear of stability of rotation is provided, with friction is reduced, improve the characteristics of service life, raising gear revolution, and pinion rotation are steady.
The embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art disclosed herein technical scope in, the change or replacement that can be expected without creative work should be all included within the scope of the present invention.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
