Abstract
The utility model provides a self-clutch unidirectional output gear, which at least includes an outer gear, a middle shaft gear, and a unidirectional button. The outer gear is annular, and a slot is arranged on the inner circumference of the outer gear. The middle shaft gear is fixed on the center of the outer gear concentrically, and the center of the middle shaft gear is fixed on the middle shaft through a spline, and the outer circumference of the outer gear is opened with a slot, the unidirectional button is arranged between the outer gear and the middle shaft gear by the connection of a connecting device, one side of the unidirectional button is provided with convex tooth protruding out. The self-clutch unidirectional output gear provided by the utility model can save energy consumption, reduce abrasion, prolong the service life; has simple structure, and is economical and practical.
Description
Technical field:
The utility model relates to a kind of driving device, and is especially a kind of from the unidirectional output gear of clutch, belongs to machinery manufacturing technology field.
Background technology:
Automobile, motor bike more and more become indispensable part in our life as walking-replacing tool.Along with it uses the increase of extensive degree, people are also more and more higher to the requirement of this walking-replacing tool, not only are confined to and can ride instead of walk, and the performance of each side has also been proposed new requirement.Energy resource saving, increase the service life, reduce all many-sides such as exhaust pollution and also become the problem that people inquire into gradually.
The driving operating mode of automobile, motor bike can have a lot of variations along with the difference of road conditions.With the automobile is example, when high speed traveling, receive oil, this moment, the speed on chassis was very high, the delivery quality of receiving oily rear engine reduces, rotating speed reduces, and the speed of driving engine is lower than chassis speed, because the transfer mode of moment is a beidirectional between driving engine and the chassis, moment is given driving engine from the chassis anti-pass, causes the waste of power and energy.Simultaneously, also can cause the mechanical wear of parts, reduction of service life.
Summary of the invention:
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of from the unidirectional output gear of clutch, reaches energy-saving and cost-reducing, reduces wear, the purpose of life-saving.
The purpose of this utility model is achieved by the following technical solution:
A kind of from the unidirectional output gear of clutch, which comprises at least external gear, countershaft-gear and unidirectional button, external gear is circular, offer groove on the ring circumference in it, countershaft-gear is installed in the center of external gear with one heart, and its center sets firmly mutually with tween drive shaft, offers notch on its outer marginal circumference, unidirectional button is connected with between external gear and countershaft-gear by connecting device, and unidirectional button one side convexes with protruding tooth.
Connecting device is that an end is installed in the center shaft gear, the other end is installed in the unidirectional spring of buckling.
The quantity of groove, notch and protruding tooth is more than one, and quantity, size and shape are corresponding one by one, are uniform on circumference.
Two outsides of external gear are also detained and are provided with block plate, play the effect of protection internal part.
In sum, the utility model provides this from the unidirectional output gear of clutch have energy-saving and cost-reducing, reduce wear, the effect of life-saving, it is simple in structure, and is economical and practical.
Description of drawings:
Fig. 1 is the utility model external gear structural representation;
Fig. 2 is the utility model countershaft-gear structural representation;
Fig. 3 is the structural representation of the unidirectional button of the utility model;
Fig. 4 is the structural representation under the utility model power transmission state;
Fig. 5 is the structural representation under the non-power transmission state of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is further detailed.
Be illustrated in figure 1 as the utility model external gear structural representation, by among the figure as can be known, the shape approximation of external gear 1 is an annular arrangement, on the side circumference, offers groove 11 within it.Groove 11 is uniform on circumference.
Be illustrated in figure 2 as the utility model countershaft-gear structural representation, by among the figure as can be known, countershaft-gear 2 also is a toroidal, it is inboard to set firmly mutually with center shaft.Offer notch 21 on outer circumference, notch 21 is uniform on circumference.
Be illustrated in figure 3 as the structural representation of the unidirectional button of the utility model, the edge that illustrates unidirectional button 3 convexes with protruding tooth 31.
The shape of the groove 11 on the shape of the protruding tooth 31 of unidirectional button 3 and external gear 1 inside circumference is corresponding.Relative position, shape and quantity homogeneous one correspondence of the notch of offering on protruding tooth 31, groove 11 and countershaft-gear 2 outer circumference 21 on circumference.
When if the hand of rotation of tween drive shaft is left-hand revolution, when the position of rotation of unidirectional button 3 arrived the correspondence position of groove 11, unidirectional button 3 also can flick under the tension force effect of spring, and protruding tooth 31 fits with groove 11.But with the variation of its position of rotation, unidirectional button 3 is slowly pushed back again.Countershaft-gear 2 drives unidirectional button 3 rotations all the time and can't drive external gear 1 motion.
Realized the effect of the unidirectional transmission of the utility model by above-mentioned mode.
Shown in the accompanying drawing is a kind of embodiment of the present utility model, and the quantity of its unidirectional button 3, groove 11 and notch 21 is four.In fact, this quantity is all can realize above-mentioned effect more than one.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
