Abstract
The utility model provides a drive for a chainless bicycle. Three bearings and a supporting element are arranged on a middle shaft, wherein, outer rings of the inner sides of two bearings are supported by a shoudler of a casing of the middle shaft; inner rings of the outer sides thereof are supported by blocking rings; another bearing is arranged on a bearing cover connected with the casing of the middle shaft; a front driving gear arranged on the middle shaft is engaged with a front driven gear of one end of a drive shaft; the other end of the drive shaft is provided with a back driving gear engaged with a back driven gear; both ends of the drive shaft are both connected with the gears adopting triangular splines bearing larger torque. Because the utility model is adopted, the drive precision and the supporting span of the middle shaft can be increased; the utility model has the advantages of smooth work, good tightness, long service life, etc.
Description
The utility model belongs to the bicycle drive system, particularly a kind of transmission device of chain-less bicycle.Before the utility model, the transmission mechanism of bicycle of selling on the market mostly is sprocket wheel, chain gear, and this transmission device driving efficiency first is low; Second take off the chain phenomenon and happen occasionally, bring many worried and troubles for the people that rides.The purpose of this utility model aims to provide a kind of chain-less bicycle transmission device, to overcome the deficiency in the existing technologies.The technical solution of the utility model realizes as follows: before establishing on axis 2, in, rear bearing 8,8a, the 8b supporting, wherein, centre bearer 8, the outer shroud of 8a inboard is supported by the shaft shoulder 14 of axis housing 1, the interior ring in its outside is by back-up ring 15, the 15a supporting, rear bearing 8b is loaded on axle 7 the inners that join with middle shell 1, adopt invoice serration 16 to be connected with axis 2 during driving gear 3 Jie are loaded on, rear bearing 8a, between the 8b, and be meshed with the preceding ring gear 3a of transmission shaft 4 one ends, and the other end of transmission shaft 4 is equipped with rear drive gear 5 and is meshed with back ring gear 5a on being loaded on rear axle 13, and transmission shaft 4 two axial ends all adopt serration 12 to be connected with rear drive gear 5a with prewave moving gear 3a respectively.
It is 2-3 that above-mentioned preceding driving gear 3 adopts speed ratio with preceding ring gear 3a: 1, and it is 1: 1 that rear drive gear adopts speed ratio with the back ring gear, gear all adopts Gleason system screw bevel gear; The back ring gear 5a the inner that is loaded in rear axle housing 6 in addition on the rear axle 13 also is provided with 10 sealings of swinging seal ring,
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 structural representation of the present utility model,
Fig. 2 the utility model axis axle construction partial enlarged drawing,
Among the figure: 1 axis housing, 2 axis, 3 preceding driving gears, ring gear before the 3a, 4 transmission shafts, 5 rear drive gears, ring gear behind the 5a, 6 rear axle housings, 7 bearing cap shims, 8 front bearings, 8a centre bearer, the 8b rear bearing, 9 side bearings lid, 10 seal rings, 11 bearings, 12 serrations, 13 rear axles, 14 shaft shoulders, 15, the 15a back-up ring, 16 invoice serrations.
As shown in Figure 1: the preceding driving gear that is meshed in the axis housing 1 of packing into and ring gear through 3: 1 speed ratio power is passed to by transmission shaft 4 be meshed in the rear axle housing 6 and speed ratio be 1: 1 rear drive gear 5 with in, back ring gear 5a on the rear axle 13 and drive rear axle rotation, front bearing 8 on the axis 2 and centre bearer 8a mainly play supporting location axis 2, thereby guarantee the running accuracy and the preceding master of axis 2, the tolerance clearance that ring gear is good, the span that increases supporting-point between bearing guarantees that axis bears the stability of external force, the rear bearing 8b that is located at bearing cap shim 7 the inners then plays the effect of aiding support axis, offset diametral load and axle external force that the previous stage gear transmission produces when stressed, above-mentioned bearing all adopts sealed bearings to press dress, installs axis housing 1 side and rear axle housing 6 sides additional bearing 11 afterwards with side bearing lid 9 and the sealing of housing flush fit at last.
Characteristics of the present utility model are: the transmission mechanism that is made up of power transmission shaft, the two pairs of bevel gears replaced in the past Chain. Chain gear transmission has improved the transmitting accuracy of axis and supported span, has the transmission stable working, and is strong Degree is high, many advantages such as good airproof performance.
