Description
Technical field
The utility model relates to a kind of new drive device, especially a kind of multiplying gear that can be used for bicycle.
Background technology
Existing bicycle is in order to improve the speed of a motor vehicle, and general the employing increases the initiatively method of the fluted disc number of teeth of bicycle.After initiatively the fluted disc number of teeth increases, the also corresponding increase of fluted disc diameter,, so neither attractive in appearance by it for folded bicycle, use also inconvenient.
Summary of the invention
The purpose of this utility model just provides a kind of axis multiplying gear.This device can reach the function of large fluted disc with small tooth plate.Both attractive in appearance, it is convenient to use again.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of axis multiplying gear, comprise an axis, five-way, be positioned at the left crank and the right crank at these axis two ends, left end cap, the five-way side is fixed with an inner gear end cap, one end of inner gear end cap is an inner gear, the other end is a right end cap, and right end cap connects with five-way, axis axially on fixing planetary gear carrier is installed, jump ring, rotating external gear, needle bearing and bottom bracket bearing, compensating-gear shaft on the planetary gear carrier parallels with axis, compensating-gear shaft axially on planetary wheel is installed, planetary wheel respectively with the inner gear and the external gear engagement of inner gear end cap, described fluted disc is fixed on the external gear.
Characteristics of the present utility model are that also the quantity of described compensating-gear shaft can change as required.
Characteristics of the present utility model are that also there is circular groove at described fluted disc middle part.
The utility model has been broken the technology mode of traditional large fluted disc transmission, has realized crank, fluted disc non-uniform movement, can reach the function of large fluted disc with small tooth plate.For folded bicycle, both attractive in appearance, it is convenient to use again.
Description of drawings:

Fig. 2: Fig. 2 is the cutaway view of A-A among Fig. 1.
Sequence number among the figure: 1 left end cap, 2 bearings, 3 jump rings, 4 five-ways, 5 axis, 6 jump rings, 7 bearings, 8 inner gear end caps, 9 planetary wheels, 10 external gears, 11 back of the body caps, 12 jump rings, 13 needle bearings, 14 fluted discs, 15 compensating-gear shafts, 16 planetary gear carriers, 17 right cranks, 18 left cranks.
Preferred forms
Below with reference to description of drawings preferred forms of the present utility model.
A kind of axis multiplying gear, comprise an axis 5, five-way 4, be positioned at the left crank 18 and the right crank 17 at these axis 5 two ends, left end cap 1, five-way 4 sides are fixed with an inner gear end cap 8, one end of inner gear end cap 8 is inner geares, the other end is a right end cap, and right end cap connects with five-way 4, axis 5 axially on bearing 2 is installed successively, jump ring 3, jump ring 6, bearing 7, planetary gear carrier 16, external gear 10, needle bearing 13 and jump ring 12, described external gear 10 are enclosed within on the needle bearing 13 on the axis 5, this axle rotation relatively; Described planetary gear carrier 16 is fixed on the axis 5, compensating-gear shaft 15 on the planetary gear carrier 16 parallels with axis 5, compensating-gear shaft 15 axially on planetary wheel 9 is installed, planetary wheel 9 is hinged on the compensating-gear shaft 15, this axle rotation relatively, between the inner gear and external gear 10 of planetary wheel 9 large internal gear end caps 8, and planetary wheel 9 respectively with the inner gear of inner gear end cap 8 and external gear 10 engagements, described fluted disc 14 is fixed on the external gear 10.
In an embodiment of the present utility model, the inner gear of establishing inner gear end cap 8 is 42 teeth, and planetary wheel 9 is 9 teeth, and external gear 10 is 22 teeth.When driving axis 5 beginnings, crank 18 rotates one downwards when pedaling 360 ° of cycles, planetary gear carrier 16 also and then rotates 360 °, the inner gear of inner gear end cap 8 maintains static, the rotation of planetary wheel 9, drive the rotation of the external gear 10 that is meshed with planetary wheel 9, planetary gear carrier 16 rotates 360 ° of external gears 10 and rotates 1008 °, and external gear 10 rotates 1008 ° of fluted discs 14 and also and then rotates 1008 °.
By above description, this driving device has been realized crank, fluted disc non-uniform movement as can be known; Be that crank rotates 360 °, fluted disc rotates 1008 °, and fluted disc 16 teeth are equivalent to 45 teeth, have reached the effect of large fluted disc with small tooth plate.Thereby reached the effect of speedup.
The foregoing description is only in order to explanation the utility model but do not limit the utility model, any change that every spirit that does not break away from the utility model claim is done and replace and all should belong to scope of the present utility model.
