Starter

Abstract

The invention provides a starter, belongs to the technical field of machinery and solves the problems that an existing starter is matched with a start cup unstably and is stressed unevenly. The starter comprises a machine body, a rotating shaft and a clutch mechanism, wherein the rotating shaft is arranged inside the machine body; the clutch mechanism is connected to the rotating shaft; the clutchmechanism comprises a claw base and a plurality of start claws, wherein the claw base is axially fixed to one end of the rotating shaft; the start claws are distributed inside the claw base in the circumferential direction; each start claw is hinged with the claw base; one side of the claw base is provided with a friction plate and an elastic part; a driving gear is fixed to one end of the rotating shaft and is positioned inside the claw base; the inner side of each start claw is provided with an engaging part which is engaged with the driving gear; the friction plate always leans against onesidewall of the machine body under the effect of the elastic force of the elastic part; the friction plate is provided with a stop part toward the claw base; and when the rotating shaft rotates in the direction where the start claws extend out of the claw base, the stop part leans against the inner sidewall of one start claw. The starter has the advantages of being better in stability, stressed more uniformly, long in service life, simple in structure and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a starter. Background technique [0002] Traditional manual starters include a housing, a rotating shaft and a scroll spring that are both arranged in the housing. The outer end of the coil spring is fixed on the casing, one end of the rotating shaft is connected to the starting mechanism and the other end of the rotating shaft is connected to the clutch mechanism. When in use, the casing of the starter is fixed on the casing of the air-cooled diesel engine. In the starting cup on the engine flywheel, the user first drives the rotating shaft to rotate through the starting mechanism to tighten the elastic force of the scroll spring, and then releases the elastic force of the scroll spring to drive the rotating shaft to reverse at high speed. Throw it out and hit the starter to spin the flywheel at high speed. However, the force when the starting claw is thrown out is very large, ...

Problems solved by technology

However, it also has obvious disadvantages: although each starting claw is unfolded by a claw plate and hinged on the same claw seat, each starting claw is actually independent of each other, and will Some starting claws are smoothly combined with the starting cup, but some starting claws and the starting cup are not effectively connected, which will cause uneven force between the starting claws, and further affect the starter and the starting cup. affect the stability of the fit
