Abstract
The utility model provides a novel crankshaft and balance shaft structure. The novel crankshaft and balance shaft structure comprises a connection rod and a crankshaft assembly, wherein one side of the crankshaft assembly is connected with a balance shaft driving gear; the balance shaft driving gear is matched and connected with a balance shaft driven gear in a transmission manner; the balance shaft driven gear is connected with a balance shaft; teeth on the balance shaft driving gear and the balance shaft driven shaft are oblique teeth; the balance shaft is located under the crankshaft assembly. By using the novel crankshaft and balance shaft structure disclosed by the utility model, the shortcoming brought by the crankshaft structure in the prior art can be well overcome, and the requirements of the customers can be better satisfied.
Description
Technical field
The utility model relates to the motorcycle engine structure, and what be specifically related to is a kind of new type crank and balance shaft structure.
Background technique
The crankshaft structure that at present motorcycle uses has following deficiency: in rural area or mountain area while using power slightly inadequate; Vibration is large, drives uncomfortable; Engine noise is large.Therefore be necessary further improvement.
Summary of the invention
In order to overcome above-mentioned technological deficiency, the utility model provides following improved technological scheme:
A kind of new type crank and balance shaft structure, comprise connecting rod, crank assemblby, described crank assemblby one side connects the trunnion shaft driving gear, described trunnion shaft driving gear coordinates and is in transmission connection with the balance shaft driven gear wheel, the trunnion shaft follower connects a trunnion shaft, wherein, the tooth on described trunnion shaft driving gear and trunnion shaft driven gear is helical teeth, and described trunnion shaft is positioned at the crank assemblby below.
Further, the outside fixed block of described trunnion shaft driving gear is the right-handed thread structure, and the outside fixed block of balance shaft driven gear wheel is the left-handed thread structure.
The utility model has adopted the lightweight crankshaft structure, reduces the kinetic energy consumption of structure, raising output power that can be by a relatively large margin; Increase balance shaft structure, removed the secondary vibration of bent axle, fundamentally solved vibration problem; Use the balancing-shaft gear structure of helical teeth instead, greatly improved the running noise of the high gear of straight-tooth structure in the past.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
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.
As shown in Figure 1, a kind of new type crank and balance shaft structure, comprise connecting rod 7, crank assemblby 6, described crank assemblby 6 one sides connect trunnion shaft driving gear 1, described trunnion shaft driving gear 1 coordinates and is in transmission connection with balance shaft driven gear wheel 4, and trunnion shaft follower 4 connects a trunnion shaft 5, wherein, tooth on described trunnion shaft driving gear 1 and trunnion shaft driven gear 4 is helical teeth, and described trunnion shaft 5 is positioned at crank assemblby 6 belows.The outside fixed block of trunnion shaft driving gear 1 is right-handed thread structure 2, and the outside fixed block of balance shaft driven gear wheel 4 is left-handed thread structure 3.This structure solves the deficiency of prototype well, has better met consumer demand.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect 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.
