Hand-cranking starter of air cooled engine

Abstract

The invention relates to a hand-cranking starter of an air cooled engine. The hand-cranking starter comprises a starting disc with the open side detachably connected with an engine air guide hood, an outer mounting disc provided with a driving shaft and an inner mounting disc provided with a driven shaft are arranged on the end face of the starting disc, and the outer mounting disc and the inner mounting disc are closed to form a cavity for accommodating a driving gear and a driven gear engaged with the driving gear. The driving gear is mounted on the driving shaft with one end extending out of the outer mounting disc, the driven gear is mounted on the driven shaft with one end extending out of the inner mounting disc, and an automatic disengaging and connecting mechanism is mounted on the extending part of the driven shaft. The hand-cranking starter is simple in structure, convenient to operate and low in cost, the cost is not increased on the basis of the price of the whole starter, and the hand-cranking starter is convenient to replace in the matching market and high in reliability; the height of the starter can be adjusted according to the heights of operators and using environments, and general popularization and sale are facilitated; and the condition that the labor in the countryside is insufficient due to the fact that currently, young people go outside to work can be effectively relieved, and the labor intensity of a user is lowered.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a hand starter for air-cooled engines. Background technique [0002] In the traditional air-cooled series engines, the starting method is mainly manual starting. During the operation of the starting device, the speed of pulling the rope, the maximum distance of pulling the rope, the angle of pulling the rope and the height of the operator’s standing position There are very strict requirements, and the requirements for the user's skills are relatively high. If they are not mastered properly, the engine cannot be started, and the engine cannot be used normally. When working in conjunction with micro tillage machines, rice transplanters, construction machinery and other machinery, and the use environment is sometimes terraced fields, some are paddy fields, so the position of the operator is inconsistent, the operating space is limited, and it is not convenient for the operator to ex...

Problems solved by technology

[0003] In this regard, some accessory manufacturers began to develop and innovate, and a brand-new energy storage starting device appeared in the market. This device uses a large volute spring to store energy to drive the structural principle of the engine. Due to the complex structure of the inner cavity, the device The weight of the assembly is heavy. When the engine is equipped with a tiller, it will cause the tiller to be heavy at one end. The tiller cannot be balanced, and it is not suitable for the light-weight use characteristics of the air-cooled engine.

The starting device has a certain improvement in the starting effect, but the requirements for the operator are further increased. If the operator makes a wrong operation, not only the engine cannot be started, but it is easy to cause injury to people.

The cost of this device is relatively high, and the sales price of the whole machine needs to be increased by more than 400 yuan on the original basis, so it has not been recognized by ordinary people.
