Abstract
The utility model discloses a power transmission device of a chainless bicycle. The power transmission device comprises a housing (1), pedals (2), a driving wheel (3), a worm (4), a driven fly wheel (5) and a bearing (6), wherein an elastic rubber ring (7) is arranged between the bearing (6) and the worm (4) in a lining mode, and the maximum radial extension distance of the inner diameter of the rubber ring (7) is two millimeters. Due to the fact that the elastic rubber ring (7) is arranged between the bearing (6) and the worm (4) in the lining mode, mechanical stray force caused by tooth engagement of a driven wheel portion is buffered in radial deformation of the rubber ring (7), and the effect that a rider feels comfortable when riding is achieved.
Description
Technical field
The utility model belongs to power transmission, more specifically to a kind of chain-less bicycle power transmission.
Background technology
The power between foot-operated driving wheel and driven flywheel is not with sprocket wheel for chain-less bicycle, and chain mode is transmitted, and with worm gear, worm screw transmission, although, overcome the shortcoming of de-chain, but, flower wheel portion by the loose assorted power of the meshing mechanicalness causing, through foot-operated driving wheel, stretcher, be transferred to cyclist, while causing riding, feel unhappy, so user is few.Therefore provide a kind of improved chain-less bicycle power transmission, tool is of great significance.
Utility model content
The purpose of this utility model is to provide a kind of chain-less bicycle power transmission.
The utility model is achieved by following technical proposals:
A kind of chain-less bicycle power transmission of the utility model, comprises case, stretcher, driving wheel, worm screw, driven flywheel, bearing, is lined with the elastomeric rubber ring of a tool between described bearing and described worm screw, the internal diameter maximum radial extension distance of described rubber ring is 2 millimeters.
The beneficial effects of the utility model are:
Owing to being lined with the elastomeric rubber ring of a tool between described bearing and described worm screw, flower wheel portion by the loose assorted power of the meshing mechanicalness causing, at described rubber ring, radially in deformation, cushioned, thereby realize, while riding, feel happy effect.
Accompanying drawing explanation
Fig. 1 is the utility model chain-less bicycle power transmission side direction perspective structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
Shown in Fig. 1, a kind of chain-less bicycle power transmission of the utility model, comprises case 1, stretcher 2, driving wheel 3, worm screw 4, driven flywheel 5, bearing 6,4 of described bearing 6 and described worm screws are lined with the elastomeric rubber ring 7 of a tool, the internal diameter maximum radial extension distance of described rubber ring 7 is 2 millimeters, as excessive, affects meshing effect.Described driving wheel 3 is worm gears, and described driven flywheel 5 is the worm gears containing non-return mechanism.
Claims (1)
1. a chain-less bicycle power transmission, comprise case (1), stretcher (2), driving wheel (3), worm screw (4), driven flywheel (5), bearing (6), it is characterized in that: between described bearing (6) and described worm screw (4), be lined with the elastomeric rubber ring of a tool (7), the internal diameter maximum radial extension distance of described rubber ring (7) is 2 millimeters.
