Abstract
The invention discloses a duplex gear for high speed revolution. The duplex gear comprises a straight gear and a plastic helical gear, wherein one side of the helical gear is provided with a connecting counter hole, the central of the connecting counter hole is axially provided with a plastic shaft sleeve with a shaft hole in a protrudent mode, the shaft sleeve and the helical gear are integrated into a whole, the peripheral shape of the connecting counter hole is matched with the tooth shape of the straight gear, the straight gear is sleeved on the shaft sleeve, the end part of the straight gear extends into the connecting counter hole and is connected with the helical gear, and the material of the straight gear is metal. The advantages of the invention are that the cost can be reduced based on the guarantee of the straight gear strength, the straight gear and the helical gear cannot slide in the high speed revolving process with strong revolving stability, and the plastic shaft sleeve and the metal gear shaft can contact with low revolving noise in the high speed revolving process of the duplex gear, the shaft sleeve and the gear shaft cannot be mutually seized because of the high temperature and also cannot be mutually seized because the friction can produce metal fillings with the result that the transmission function disappears.
Description
Technical field
The present invention relates to a kind of duplicate gear, especially relate to a kind of duplicate gear for High Rotation Speed.
Background technique
The device of High Rotation Speed generally comprises power system, transmission system and work system, and transmission system arrives work system, the High Rotation Speed of implement device by the power transmission of power system output; The transmission system of some high speed rotating unit is mainly to realize the transmission of power by duplicate gear, such as paper breaker; Duplicate gear generally comprises helical gear and spur gear, duplicate gear mainly contains three kinds at present: in the first duplicate gear, helical gear and spur gear are by integrally moulded, in the second duplicate gear, helical gear and spur gear are one-body molded by metal, in the third duplicate gear, helical gear is plastic material, spur gear is metal material, and helical gear is connected with spur gear; In transmission system, duplicate gear is arranged on gear shaft, in the power transmission process, the helical gear of duplicate gear is connected with power system, the spur gear of duplicate gear is connected with work system, drive the work system High Rotation Speed, the impact force that wherein spur gear bears is helical gear several times, the transmission impact force of duplicate gear is mainly born by spur gear, the helical gear of above-mentioned the first duplicate gear and spur gear are all plastics, although noise is low in rotation process, intensity is also low, usually because bearing powerful impact force, produces wearing and tearing and scraps; The helical gear of above-mentioned the second duplicate gear and spur gear are all metal material, although its intensity is high, but its manufacture cost is also high, in the High Rotation Speed process, noise is larger, and gear shaft is also generally metal material, in the High Rotation Speed process, between spur gear and gear shaft, the phase mutual friction produces high temperature, easily cause spur gear and gear shaft to be killed, transmission agency disappears, and the mutual fricative metal fillings between spur gear and gear shaft also can cause spur gear and gear shaft to be killed in addition, and transmission agency disappears; Although the cost of above-mentioned the third duplicate gear is lower than above-mentioned the second duplicate gear cost, also there is the large drawback of killing with easy and gear shaft of noise of above-mentioned the second duplicate gear in it.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of noise is low, and intensity is high, can in the High Rotation Speed process, with gear shaft, not kill the duplicate gear of phenomenon.
The present invention solves the problems of the technologies described above adopted technological scheme: a kind of duplicate gear for High Rotation Speed, the helical gear that comprises spur gear and plastics, a described helical gear side is provided with the connection counterbore, the center axial projection of described connection counterbore is provided with the axle sleeve of plastics, be provided with axis hole in described axle sleeve, described axle sleeve and described helical gear are one-body molded, the peripheral shape of described connection counterbore and the profile of tooth of described spur gear coupling, described spur gear is set on described axle sleeve, the end of described spur gear enters in described connection counterbore and is connected with described helical gear, described spur gear is metal material.
The material of described helical gear and described axle sleeve is polyoxymethylene POM or nylon.
Compared with prior art, the invention has the advantages that: the spur gear of metal is set on the axle sleeve of plastics, and be connected with the helical gear of plastics by connecting counterbore, reduced cost on the basis that guarantees spur gear intensity, not only spur gear and helical gear can not slide in the High Rotation Speed process, rotational stability is strong, and in duplicate gear High Rotation Speed process, the axle sleeve of plastics contacts with the gear shaft of metal, the rotation noise is low, between axle sleeve and gear shaft, can mutually not kill because of high temperature, can not cause axle sleeve and gear shaft to be killed because friction produces metal fillings yet, so that transmission agency disappears.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The structural representation that Fig. 2 is helical gear of the present invention and axle sleeve;
The structural representation that Fig. 3 is spur gear of the present invention;
Fig. 4 is sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
Embodiment one: as shown in Fig. 1 ~ Fig. 3, a kind of duplicate gear for High Rotation Speed, the helical gear 1 that comprises spur gear 4 and plastics, one side of helical gear 1 is provided with and connects counterbore 5, the center axial projection that connects counterbore 5 is provided with the axle sleeve 2 of plastics, be provided with axis hole 3 in axle sleeve 2, axle sleeve 2 is one-body molded with helical gear 1, connect the peripheral shape of counterbore 5 and the profile of tooth coupling of spur gear 4, spur gear 4 is set on axle sleeve 2, the end of spur gear 2 enters and connects in counterbore 5 and be connected with helical gear 1, and spur gear 4 is metal material.
In above-mentioned specific embodiment, the material of helical gear 1 and axle sleeve 2 is polyoxymethylene POM or nylon.
