Abstract
The utility model relates to a leather belt driving device of an air distributing mechanism of a small 4-stroke internal combustion engine. The utility model comprises a driving wheel, a driven wheel and a driving belt. The driving wheel and the driven wheel adopt gear wheels. The driving belt is a toothed belt, whrein, the inner side of the toothed belt is provided with teeth which are meshed with the teeth of the driving wheel and the driven wheel. The utility model has the advantages that the toothed belt with definite elasticity can obviously lessen double-reverse rising and expanding power of a valve and a piston caused by the fierce shock of an engine to ensure that next circulation can smoothly continue, air distributing work can be achieved more accurately, a driving mechanism does not slip or deform, transmission loss is lowered, and noise and mechanical wear are obviously lowered to basically achieve the effect of mute, so the service life of the engine is prolonged. The utility model can be suitable for power transmission of high, middle and low speed, the manufacturing and maintaining cost of the utility model is lowered, and energy is saved.
Description
Technical field
The utility model relates to a kind of belt drive unit of small-size four-stroke ic machine distribution device, is mainly used in the motorcycle general type motor.
Background technique
Existing mini engine all is to adopt chain type and post rod type distribution driving mechanism.Its common shortcoming is that noise is big, and wearing and tearing are big, and the distribution inaccuracy is steady, and maintenance difficulty is big.
Summary of the invention
The purpose of this utility model just provides a kind of belt drive unit of small-size four-stroke ic machine distribution device, and the noise that exists with the solution prior art is big, and wearing and tearing are big, and the distribution inaccuracy is steady, and the big problem of maintenance difficulty.
The technical solution of the utility model is: comprise driving wheel, follower and driving belt, described driving wheel and follower adopt gear, and described driving belt is a cingulum, and the inboard of this cingulum is provided with the tooth that is meshed with the tooth of described driving wheel and follower.
Side at the cingulum between described two gears is provided with the degree of tightness regulating wheel.
Described cingulum is made by rubber.
The utility model has the advantages that: have certain flexible cingulum and can obviously alleviate valve and the two expansion power that oppositely rise of piston that cause in pinking two owing to motor, guarantee that next cyclo-stationary ground continues, it is more accurate to reach distribution work, non-slip and the distortion of driving mechanism, reduced transmission loss, obviously reduce noise and mechanical wear, reached quiet effect substantially, thereby prolonged the working life of motor; Can be suitable for the transmission of power of high, medium and low speed, reduce manufacture cost and maintenance expenses, save the energy.
