Abstract
The utility model relates to an internal ratchet combined gear wheel which belongs to an internal speed change gear wheel of a bicycle. The internal ratchet combined gear wheel is composed of a bevel gear wheel, a straight gear wheel and a cylindrical connector, wherein the bevel gear wheel is connected with the straight gear wheel through the cylindrical connector to form an integral structure, the inner wall surface is the same cylindrical surface, the inner wall of the internal ratchet combined gear wheel is provided with an annular circlip groove, and the inner wall of the straight gear wheel is provided with a plurality of inner ratchets which are in circular permutation. The internal ratchet combined gear wheel can be sheathed on a central shaft of an internal speed change bicycle and can be matched with a bevel gear assembly, on-off keys and a ratchet pawl assembly to realize speed change of the bicycle. The utility model has the advantages of flexible operation, stable performance and convenient stage shift.
Description
The utility model relates to a kind of gear, particularly relates to a kind of interior sour jujube compound gear that is used on the internal speed variator of bicycle.
Bevel gear is contained on the same axis at present, can not speed change.Change-speed box on the commercially available bicycle is to adopt to be contained in variable gear assembly that each tooth radius on the axis varies in size and to cooperate with chain and finish speed change, there are a lot of shortcomings in this speed change, exposed outside as the variable gear assembly, neither attractive in appearance, fragile again, the variable speed operation underaction, speed change retaining is time few etc.
The purpose of this utility model, provide a kind of have save the space, dwindle the change speed gear box volume, reduce the quantity of gear wheel shaft and improve the power utilization rate, can on same axle, realize the interior sour jujube compound gear of multi-change speed.
The purpose of this utility model adopts following technical proposals to realize, that is:
Interior sour jujube compound gear comprises bevel gear, straight gear and cylinder connector.Wherein, bevel gear and straight gear connect into an integral structure by the cylinder connector.And the internal face of bevel gear and straight gear and cylinder connector is the same face of cylinder.
Its wheel face of above-mentioned bevel gear is interior dip plane, also can be the flare inclined-plane, and an annular spring groove is arranged on the inner wall surface thereof.
Be evenly equipped with a plurality of interior ratchets of arranging in the form of a ring on its inwall of above-mentioned straight gear.
Interior sour jujube compound gear can be used as the variable gear that the internal speed-changing of variable speed bicycle is used, and also can use on other varying-speed machinery.The sour jujube compound gear is combined in a plurality of, and is contained on the axis of inner speed change bicycle, with unit constructions such as bevel gear component, clutch key or pawl assemblies, constitutes the change-speed box of inner speed change bicycle.(being filled with oil in the change speed gear box of inner speed change bicycle).
Advantages such as the variable speed bicycle that adopts this kind change-speed box to make has good looking appearance, variable gear does not expose (being located in the change speed gear box), and is simple to operate, and gearshift is flexible, and many gears are durable in use, and sprocket wheel is little, and is easy to maintenance.
Fig. 1 is the structural representation of first kind of embodiment of the utility model, and Fig. 2 is the right elevation of Fig. 1, and Fig. 3 is the structural representation of second kind of embodiment of the utility model, and Fig. 4 is the right elevation of Fig. 3.The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment one
Interior sour jujube compound gear comprises bevel gear 1, straight gear 2, cylinder connector 3.Wherein, bevel gear 1 is captiveed joint with straight gear 2 by cylinder connector 3, and bevel gear 1 and straight gear 2 and cylinder connector 3 are an integral structure, and internal face is the same face of cylinder.The wheel face of bevel gear 1 is interior dip plane, and an annular spring groove 4 is arranged on the inner wall surface thereof; The wheel face of straight gear 2 is the face of cylinder, is evenly equipped with a plurality of interior ratchets of arranging in the form of a ring 5 on its inwall.
Embodiment two
Interior sour jujube compound gear comprises bevel gear 1, straight gear 2 and cylinder connector 3.Wherein, bevel gear 1 is captiveed joint with straight gear 2 by cylinder connector 3, and is an integral structure.The internal face of bevel gear 1 and straight gear 2 and cylinder connector 3 is the same face of cylinder.The wheel face of bevel gear 1 is the flare inclined-plane, and its inwall is provided with an annular spring groove 4; The wheel face of straight gear 2 is the face of cylinder, is evenly equipped with a plurality of interior ratchets of arranging in the form of a ring 5 on its inwall.
