Abstract
The utility model discloses a novel accurate variable speed chain wheel of cochain nail, be in with the setting including right crank the last fluted disc of right crank, the fluted disc has at least two -stage and adjusts bits for the speed of a motor vehicle, except that the most rudimentary regulation for the speed of a motor vehicle all the other bitss the bits cochain spare of a plurality of be used for lead cochains is provided with towards the terminal surface periphery of rudimentary bits. The utility model has the advantages of at the cochain in -process, chain from rudimentary bits in to senior bits motion process can be along cochain spare direction, makes that the chain is accurate to fall into senior bits, realizes accurate variable speed.
Description
Technical field
The utility model relates to tooth dish field, follows closely accurate speed change tooth dish in particular to the novel cochain of one.
Background technology
Current speed change tooth dish generally comprises right crank and the fluted disc being connected on right crank, and fluted disc comprises the gear piece of some concentric settings and external diameter gradual change, moves on the gear piece of different positions by gear shift mechanism by chain, it is achieved speed change. But between the gear piece of current speed change tooth dish, cochain guiding mechanism is not set, causes frequent cochain failure in speed-change process, or cochain precision is lower.
Practical novel content
The purpose of this utility model is for shortcomings and deficiencies of the prior art, it is provided that accurate speed change tooth dish followed closely by a kind of novel cochain, to solve the problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Accurate speed change tooth dish followed closely by novel cochain, comprise right crank and the fluted disc being arranged on described right crank, described fluted disc has at least two-stage and regulates speed of a motor vehicle gear piece, and all the other gear pieces except lowermost level regulates speed of a motor vehicle gear piece are provided with some upper chain element in order to the cochain that leads towards the end face periphery of rudimentary gear piece.
In a preferred embodiment of the present utility model, described upper chain element comprises the rivet being riveted on gear piece, and one end of described rivet is fixed face, and the other end is guiding face, and described guiding face is oval face structure.
In a preferred embodiment of the present utility model, described fluted disc comprises the inner blade and outer gear piece that are connected on described right crank, and the flank of tooth diameter of described inner blade is less than the flank of tooth diameter of outer gear piece, and described upper chain element is arranged on the inner face of described outer gear piece.
Owing to have employed technical scheme as above, the beneficial effects of the utility model are: in upper chain process, and chain, from rudimentary gear piece to, senior gear piece moving process, leading along upper chain element, makes chain precisely fall into senior gear piece, it is achieved precisely speed change.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, it is briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the front view of a kind of embodiment of the utility model.
Fig. 2 is the I place enlarged view of Fig. 1.
Fig. 3 is that the A-A of Fig. 2 is to sectional view.
Embodiment
In order to the utility model is realized technique means, creation characteristic, reach object and effect is easy to understand, set forth the utility model below further.
See shown in Fig. 1 to Fig. 3, novel cochain is followed closely accurate speed change tooth dish and is comprised right crank 100 and the fluted disc 200 being arranged on right crank 100, fluted disc 200 has at least two-stage and regulates speed of a motor vehicle gear piece, and all the other gear pieces except lowermost level regulates speed of a motor vehicle gear piece are provided with some upper chain element 300 in order to the cochain that leads towards the end face periphery of rudimentary gear piece. In the present embodiment, fluted disc 200 has two-stage and regulates speed of a motor vehicle gear piece, namely fluted disc 200 comprises the inner blade 210 and outer gear piece 220 that are connected on right crank 100, the flank of tooth diameter of inner blade 210 is less than the flank of tooth diameter of outer gear piece 220, so inner blade 210 is equivalent to rudimentary adjustment speed of a motor vehicle gear piece, outer gear piece 220 is equivalent to rudimentary adjustment speed of a motor vehicle gear piece. Certainly, fluted disc 200 can also comprise three grades and regulate speed of a motor vehicle gear piece, and its principle regulates speed of a motor vehicle gear piece the same with two-stage, does not just repeat at this.
Upper chain element 300 comprises the rivet 310 being riveted on outer gear piece 220, and one end 311 of rivet 310 is fixed face, and the other end is guiding face 312, and guiding face 312 is oval face structure.
Principle of work of the present utility model is as follows:
In upper chain process, chain 400 is from rudimentary gear piece to senior gear piece moving process, can lead along the guiding face 312 of upper chain element 300, and the guiding face 312 of oval face structure is mutually adaptive with the cambered surface 411 in the middle part of the chain subelement 410 of chain 400, chain 400 is made precisely to fall into senior gear piece, it is achieved precisely speed change.
More than show and describe ultimate principle of the present utility model and main characteristic sum advantage of the present utility model. The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model. The claimed scope of the utility model is defined by appending claims and equivalent thereof.
