Detailed description of the invention
Embodiment one:
The present embodiment is the rapid transmission method of a kind of plate type quantitative conveyer, and described method is: when designing board-like conveyer chain transmission, arranges many group sprocket wheels and chain, and in pitch, mean allocation respectively organizes the meshing point of sprocket wheel, shortens each group of sprocket wheel load time.
As it was previously stated, the plate type quantitative conveyer described in the present embodiment needs to bear bigger dead load and movement load, therefore, the facewidth of its sprocket wheel must carry out strict strength check, and its result creates the most plump profile of tooth, as shown in Figure 1.The most plump profile of tooth means that the design of sprocket wheel is necessarily limited to bigger pitch, to meet this requirement of strength.The sprocket wheel then pitch bigger for intended diameter is not a problem more greatly, but in actual design, is limited to the volume of conveyer profile, tends not to according to bigger pitch design sprocket wheel.Meanwhile, in sprocket design, for ensureing the stationarity of chain movement, teeth number of sprocket to be increased, reduction pitch.Therefore in the case of load is relatively big, in the case of particularly dynamic loading changes greatly, traditional sprocket wheel and chain design cannot solve carrying, at a high speed and steadily between contradiction.
Because it is a gradually process that the gear teeth bear load, it is that tradition sprocket wheel bears the process of load as shown in Figure 1.When gear teeth A drives chain roller a；At this moment gear teeth B comes into contact with chain roller b, when gear teeth B drives chain roller b；Gear teeth C comes into contact with chain roller c, so constantly circulation.The gear teeth of tradition sprocket wheel stress F when draw chain moves, on the gear teeth1 -F2-F3The amplitude jumped is bigger.The force-bearing situation of this gear teeth is poor, and the polygon of sprocket wheel is corresponding more obvious, is unfavorable for mentioning linear velocity.
It is pitch cutting stress that the present embodiment solves the thinking of this problem: the multiple sprocket wheels in chain wheel set drive a plurality of chain, a pitch distributes multiple meshing point, sprocket wheel is made constantly to have the gear teeth of carrying to add in loading procedure, shorten each gear teeth independent carrying time when entering engagement, load is constantly assigned on the engaging tooth of multiple sprocket wheel.As shown in Figure 2, a sprocket wheel with gear teeth HK (representing in Fig. 1) is added by fine line on the basis of Fig. 1 has the sprocket wheel (representing in Fig. 1) of the ABC gear teeth with heavy line, two sprocket diameters, profile of tooth, pitch are the most identical, simply differ half pitch, increase a chain simultaneously.When gear teeth A drives chain roller a, gear teeth H also to be pulled by chain roller h, and simply stress is the most a little bit smaller, gear teeth B drives chain roller b simultaneously, and a little bit smaller by force rate gear teeth B, gear teeth K also drives chain roller k simultaneously, gear teeth C comes into contact with chain roller c, so constantly circulation.In terms of engagement situation from Fig. 2, in a pitch, sprocket wheel is divided into two deciles, from F with the engaging stress of chain1 - F4-F2-
F5-F3The stress amplitude being gradually increased is better than the sprocket wheel shown in Fig. 1, reduces the impact of polygon effect, improves linear velocity.
Can also increase the number of sprocket wheel and chain, such as three sprocket wheels and three chains, pitch is divided into trisection, the stress amplitude that sprocket wheel engages with chain increases more steady, and the impact of polygon effect reduces further, and linear velocity improves further.Apparent load situation, it is also possible to increase more multi-sprocket and chain.
Above-mentioned method increases a sprocket wheel will increase a chain.Owing to the allowable load of chain is often higher than the allowable load of the gear teeth, and hence it is also possible to make in another way: in the case of not increasing chain number, increasing sprocket wheel, i.e. two sprocket wheels share a chain, it is also possible to the method realizing above-mentioned pitch cutting.The such as side at chain arranges extra roller, drives with sprocket wheel, produces the effect of distribution power.
