Abstract
The utility model discloses an abrasion uniformizing device for drive gears of a chain-free drive bicycle. The device comprises pedals, two cranks, a first bevel gear, a ratchet wheel, a center shaft, a second bevel gear, a drive shaft, a third bevel gear, a fourth bevel gear and a rear wheel shaft, wherein the two cranks are arranged at the two ends of the center shaft respectively; the pedals are arranged at the ends, away from the center shaft, of the cranks; the ratchet wheel is sleeved in the first bevel gear; the first bevel gear is sleeved on the center shaft; the second and third bevel gears are arranged at the two ends of the drive shaft respectively; the second bevel gear is matched with the first bevel gear; the fourth bevel gear is sleeved on the rear wheel shaft, and is matched with the third bevel gear. According to the device, a mode of combined drive of a plurality of bevel gears is adopted, and abrasion produced in a drive process can be uniformly distributed to each gear, so that an abrasion value between the gears can be minimized, the service life of a drive device can be prolonged, and the market competitiveness of a product is improved.
Description
Technical field
The utility model relates to a kind of no chain drive bike transmission gear uniform wear device.
Background technology
In recent years, no chain drive bike, because of its stable performance, obtains application more and more widely.Yet in bicycle crank rotates a circle, when crank throw is in about vertical position each 45 ° time, now people's pin and the angle between crank throw are very little, so be difficult to apply tangential force to crank throw.Only have when crank throw be horizontal left and right each 45 ° time, the talent is convenient applies power to crank throw.For the gear in driving system, just only in each a part of tooth of 45 ° of horizontal surface left and right, just play the effect of carry-over moment, therefore, wearing and tearing only concentrate in this part of tooth, and other tooth does not does not wear and tear substantially.In this device, can make transmission gear even wearing distribute, thereby extend the service life of driving system, improve the competitiveness of product in market.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of even wearing can being distributed in each gear, makes the no chain drive bike transmission gear uniform wear device of longer service life.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of no chain drive bike transmission gear uniform wear device, comprise foot-operated, crank throw, the first finishing bevel gear cuter, ratchet, axis, the second finishing bevel gear cuter, transmission shaft, third hand tap gear, the 4th finishing bevel gear cuter and hind axle, described crank throw is provided with two, be separately positioned on axis two ends, described riding is arranged on crank throw away from one end of axis, described ratchet sleeve is located in the first finishing bevel gear cuter, described the first finishing bevel gear cuter is set on axis, described the second finishing bevel gear cuter and third hand tap gear are separately positioned on the two ends of transmission shaft, described the second finishing bevel gear cuter matches with the first finishing bevel gear cuter, described the 4th finishing bevel gear cuter is set on hind axle, and match with third hand tap gear.
As preferred technical scheme, described two crank throws are all perpendicular with axis, and between two crank throws, install at Cheng180° angle.
As preferred technical scheme, described transmission shaft is vertical with axis to be arranged.
As preferred technical scheme, described hind axle is vertical with axis to be arranged and be arranged in parallel with transmission shaft.
The beneficial effects of the utility model are: by adopting the form of a plurality of finishing bevel gear cuter combination transmissions, the even wearing producing in transmission process can be distributed in the middle of each gear, make the wear value between each gear reach minimum, increase the service life of driving device, thereby improved the competitiveness of product in market, and the utility model structure is comparatively simple, use and install more for convenience, be applicable to promoting the use of.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model no chain drive bike transmission gear uniform wear device.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Consult a kind of no chain drive bike transmission gear uniform wear device shown in Fig. 1, comprise foot-operated 1, crank throw 2, the first finishing bevel gear cuter 3, ratchet 4, axis 5, the second finishing bevel gear cuter 6, transmission shaft 7, third hand tap gear 8, the 4th finishing bevel gear cuter 9 and hind axle 10, described crank throw 2 is provided with two, be separately positioned on axis 5 two ends, described foot-operated 1 is arranged on crank throw 2 away from one end of axis 5, described ratchet 4 is set in the first finishing bevel gear cuter 3, described the first finishing bevel gear cuter 3 is set on axis 5, described the second finishing bevel gear cuter 6 and third hand tap gear 8 are separately positioned on the two ends of transmission shaft 7, described the second finishing bevel gear cuter 6 matches with the first finishing bevel gear cuter 3, described the 4th finishing bevel gear cuter 9 is set on hind axle 10, and match with third hand tap gear 8.
Wherein, described two crank throws 2 are all perpendicular with axis 5, and between two crank throws 2, install at Cheng180° angle.
The setting vertical with axis 5 of described transmission shaft 7.
The setting vertical with axis 5 of described hind axle 10 also be arranged in parallel with transmission shaft 7.
The beneficial effects of the utility model are: by adopting the form of a plurality of finishing bevel gear cuter combination transmissions, the even wearing producing in transmission process can be distributed in the middle of each gear, make the wear value between each gear reach minimum, increase the service life of driving device, thereby improved the competitiveness of product in market, and the utility model structure is comparatively simple, use and install more for convenience, be applicable to promoting the use of.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
