Abstract

The invention discloses a hand-cranking starter of a diesel engine, and aims at providing a diesel engine hand-cranking starter which is convenient to use, small in starting impact and long in service life. The hand-cranking starter comprises a machine shell, a rotating shaft, a big gear wheel, a flat spiral spring, a small gear wheel and a shifting fork, wherein one side of the machine shell is detachably connected with a diesel engine shell, the rotating shaft is installed on the two side walls of the machine shell through bearings, the big gear wheel is installed on the side, far away from the diesel engine shell, of the rotating shaft and located in the machine shell, the flat spiral spring is installed on the side, close to the diesel engine shell, of the rotating shaft and located in the machine shell, the small gear wheel is installed on the side, far away from the diesel engine shell, in the machine shell and is meshed with the big gear wheel, and the shifting fork is used for locking the big gear wheel and connected with a handle. The hand-cranking starter is characterized in that the end, close to the diesel engine shell, of the rotating shaft extends out of the machine shell and is provided with a ratchet wheel type overrun clutch which comprises an outer wheel and a core wheel located in the outer wheel, and the core wheel is provided with a plurality of pawls and fixedly connected with the rotating shaft. The hand-cranking starter is suitable for various mini-tillers, agricultural irrigation and drainage devices and other household machines.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a hand crank starter for diesel engines. Background technique [0002] At present, most of the diesel engines of household machinery such as micro-tillers, three-wheeled agricultural transport vehicles, engineering vehicles, agricultural irrigation and drainage equipment, and water transport machines and sailboats used in agriculture are started by manual starters. The stay cord is easy to be damaged and broken, which causes a lot of inconvenience to use. [0003] Subsequently, a hand-cranked starter appeared, such as the attached figure 1 As shown, the outer ring of the plane scroll spring is fixed on the casing, and the inner ring is fixed on the rotating shaft; a large gear is also fixed on the rotating shaft, and the rotating shaft is fixed on the two side walls of the casing by bearings, and the shift fork is locked on the rotating shaft. The large gear prevents the...
