Abstract
The utility model relates to a spherical bevel gear transmission system for a chainless bicycle. The system comprises bicycle pedals, a driving shaft and a driven shaft, wherein the driving shaft and the driven shaft form a certain included angle; the driving shaft is driven by the bicycle pedals; a driving shaft spherical bevel gear is arranged on the driving shaft, and a driven shaft spherical bevel gear is arranged on the driven shaft; a transmission shaft is arranged between the driving shaft and the driven shaft, and the central axis of the transmission shaft forms an included angle with the horizontal line; an upper transmission shaft spherical bevel gear and a lower transmission shaft spherical bevel gear are arranged on the two end parts of the transmission shaft respectively. The system is simple in structure and reasonable in design; a spherical bevel gear transmission mode is adopted, and the transmission stability can also be ensured within certain spherical gear transmission deviation, so that normal transmission and higher riding comfort of the bicycle can be maintained under the condition of riding on an uneven road or vibration and bumping; due to the adoption of the scheme, the accuracy requirements of a bicycle frame can be greatly lowered, the transmission system failure rate caused by the deformation of the bicycle frame can be lowered, and meanwhile, stable transmission and high comfort are ensured.
Description
Technical field
The utility model relates to the technical field of bicycle transmission system, especially a kind of bevel gear tooth system with sphere of chain-less bicycle.
Background technology
In known technical field, bicycle is a kind of vehicle common in people's daily life, the drive system of bicycle generally comprises: pedal, axis, chain wheel, crank, chain, flywheel, the parts such as rear axle and trailing wheel form, the power of pedaling of people's pin is to pass through crank by pedal, sprocket wheel, chain, flywheel, the parts transmissions such as rear axle, thereby bicycle is constantly advanced, in life, common bicycle is all the chain-drive bicycle with chain, and this bicycle is when riding, likely can there is de-chain, the fault of chain rupture, to people, make troubles, therefore, a kind of chain-less bicycle just arises at the historic moment, the general use of chain-less bicycle be all the gear transmission with finishing bevel gear cuter, in this transmission, the angle of two finishing bevel gear cuters is fixing immutable, when bicycle runs into frustration in the process of riding, its integral structure vibrates, can produce the bad situation of engagement, the traveling comfort that impact is ridden.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provide a kind of efficiently convenient, transferring power is stablized, possess the bevel gear tooth system with sphere of the chain-less bicycle of certain flexibility self-adjusting ability.
The utility model solves the technical scheme that its technical matters adopts: a kind of bevel gear tooth system with sphere of chain-less bicycle, comprise bicycle pedal, there is vertical and spaced imput shaft and driven shaft, described imput shaft is driven by bicycle pedal, on described imput shaft and driven shaft, be respectively equipped with imput shaft spherical bevel gear and driven shaft spherical bevel gear, between described imput shaft and driven shaft, be provided with the transmission shaft that central axis and horizon are mutually angle, and described imput shaft, the central axis of transmission shaft and driven shaft is all in the same plane, at the both ends of described transmission shaft, be provided with respectively and upload moving axis spherical bevel gear and lower drive shaft spherical bevel gear, and described in upload moving axis spherical bevel gear and lower drive shaft spherical bevel gear respectively with imput shaft spherical bevel gear and the engagement of driven shaft spherical bevel gear.
Further, as a kind of concrete embodiment, the angle forming between the central axis of transmission shaft described in the utility model and horizon is 10 °.
Further, as a kind of concrete embodiment, the angle forming between the central axis of transmission shaft described in the utility model and horizon is 15 °.
Further, as a kind of concrete embodiment, the angle forming between the central axis of transmission shaft described in the utility model and horizon is 20 °.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, employing is with the bevel drive of sphere, Spherical Gears is in having certain deviation, also can guarantee the stationarity of transmission, can make like this bicycle travel or vibrate jolt in the situation that at uneven road surface and also can keep the traveling comfort of riding preferably, this programme can reduce the fault rate of bicycle greatly, while stable drive, traveling comfort is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. imput shaft, 2. imput shaft spherical bevel gear, 3. uploads moving axis spherical bevel gear, 4. transmission shaft, 5. lower drive shaft spherical bevel gear, 6. moving axis spherical bevel gear, 7. driven shaft.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
The preferred embodiment of the bevel gear tooth system with sphere of a kind of chain-less bicycle of the utility model as shown in Figure 1, comprise bicycle pedal, it is characterized in that: there is vertical and spaced imput shaft 1 and driven shaft 7, described imput shaft 1 is driven by bicycle pedal, on described imput shaft 1 and driven shaft 7, be respectively equipped with imput shaft spherical bevel gear 2 and driven shaft spherical bevel gear 6, between described imput shaft 1 and driven shaft 7, be provided with the transmission shaft 4 that central axis and horizon are mutually angle, and described imput shaft 1, the central axis of transmission shaft 4 and driven shaft 7 is all in the same plane, at the both ends of described transmission shaft 4, be provided with respectively and upload moving axis spherical bevel gear 3 and lower drive shaft spherical bevel gear 5, and described in upload moving axis spherical bevel gear 3 and lower drive shaft spherical bevel gear 5 respectively with imput shaft spherical bevel gear 2 and 6 engagements of driven shaft spherical bevel gear.
The angle forming between the central axis of described transmission shaft 4 and horizon is 10 °, also can be 15 ° or 20 °, and concrete angle can be adjusted according to actual wheelbase and other situations.
When riding, by bicycle pedal, imput shaft 1 is rotated, drive imput shaft spherical bevel gear 2, then drive the rotation of driven shaft spherical bevel gear 6 by transmission shaft 4, and then driven shaft 7 is rotated, thereby realize the motion of bicycle.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to claim scope.
