Abstract

The invention provides a compact internal combustion engine starter externally provided with an electromagnetic switch, and belongs to the technical field of internal combustion engine starters. The problems that in the prior art, the fault rate is high, and the length of the whole machine cannot be reduced easily are mainly solved. The internal combustion engine starter comprises a drive shaft, a shifting fork, a first shell, the external electromagnetic switch and a motor rotating shaft. The internal combustion engine starter is characterized by further comprising a one-way speed reduction device and a buffering device; the one-way speed reduction device comprises a speed reduction device and a one-way device, the speed reduction device is a planetary gear speed reducer and comprises a first planetary speed reducer inner gear ring or a second planetary speed reducer inner gear ring and a speed reduction drive shaft; the one-way device comprises a first one-way speed reduction device shell and a friction braking device; the first one-way speed reduction device shell is in a barrel shape, a first spring roller groove is formed in the inner wall of the first one-way speed reduction device shell, and a first outer clamping table is arranged on the outer wall of the first one-way speed reduction device shell; and the first planetary speed reducer inner gear ring is sleeved with the first one-way speed reduction device shell. The buffering device is composed of a buffering block, an inner clamping table and an outer clamping table.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engine starters, in particular to a compact internal combustion engine starter with an external electromagnetic switch. Background technique [0002] At present, most internal combustion engine starters are deceleration starters. Regardless of the eccentric deceleration structure or the starter of the planetary deceleration structure, the deceleration structure and the one-way device are on the same starter, and are axially connected and installed in sequence. The commonly used roller checker has a high failure rate, and the length of the whole machine is not easy to shorten, which is the bottleneck of the development of the same power, miniaturization and light weight technology in the starter industry. Contents of the invention [0003] The purpose of the present invention is to solve the problems of the prior art that the starter has a long length and rigid contact, the electroma...
