Abstract
A star wheel for an isolator of an automobile starter comprises a star wheel body (1) which includes a large column body (1.1) and a small column body (1.2). A knurl (2) is arranged at the connection position of the lateral wall of the large column body (1.1) and an end face close to the small column body (1.2). The star wheel enables a hemming of a casing and corners of the star wheel to be sleeved firmly, thereby effectively avoiding falling.
Description
Technical field:
The utility model relates to a kind of constituent elements of automobile starter one-way element, specifically is a kind of star wheel that is used for the automobile starter one-way element.
Background technique:
The star wheel that is used for the one-way element of automobile starter generally is made up of diameter bigger big cylinder and the less paxilla of diameter.Be set with outer cover on the said big cylinder; Be used to cover the connection part (being left corner segment position and right corner segment position) of sidewall, both ends of the surface and the sidewall of big cylinder; But in actual use; Crimping and the right corner segment position suit that is used to cover the right corner segment position on the outer cover gets firm inadequately, is prone to take place obscission.
The model utility content:
The technical problem that the utility model will solve is to provide a kind of crimping of outer cover and turning suit must compare firmly, the difficult star wheel that is used for the automobile starter one-way element that obscission takes place.
For solving the problems of the technologies described above; The utility model adopts a kind of like this star wheel that is used for the automobile starter one-way element; It comprises the star wheel body, and said star wheel body comprises big cylinder and paxilla, and the sidewall of said big cylinder is provided with annular knurl with connection part near the end face of paxilla.
Said annular knurl is a straight knurling.
The sidewall of said big cylinder is a plane of inclination with connection part near the end face of paxilla, and said annular knurl is arranged on this plane of inclination.
After adopting above structure; The utility model compared with prior art; Have the following advantages: because the sidewall of said big cylinder is provided with annular knurl with connection part (being the right corner segment position) near the end face of paxilla; Being provided with of this annular knurl increased surface friction drag, and the right corner segment position suit of crimping and big cylinder of being convenient to be used to cover the right corner segment position of big cylinder gets firmly, is difficult for taking place obscission.
As improvement, said annular knurl is a straight knurling, and straight knurling is easy to process.
As further improvement, the sidewall of said big cylinder is a plane of inclination with connection part near the end face of paxilla, and said annular knurl is arranged on this plane of inclination, is convenient to the machine shaping of annular knurl.
Description of drawings:
Fig. 1 is the broken section structural representation of automobile starter one-way element that is equipped with the star wheel of the utility model.
Fig. 2 is the amplification axle side structure schematic representation of the star wheel among Fig. 1.
Shown in the figure: 1, star wheel body, 1.1, big cylinder, 1.2, paxilla, 2, annular knurl, 3, outer cover, 3.1, crimping.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As depicted in figs. 1 and 2, the utility model is used for the star wheel of automobile starter one-way element, and it comprises star wheel body 1, and said star wheel body 1 comprises big cylinder 1.1 and paxilla 1.2.The diameter of said big cylinder 1.1 is greater than the diameter of paxilla 1.2.The sidewall of said big cylinder 1.1 is provided with annular knurl 2 with connection part (being right corner segment position as shown in Figure 1) near the end face of paxilla 1.2.
As the improvement project of present embodiment, said annular knurl 2 is a straight knurling.The sidewall of said big cylinder 1.1 is a plane of inclination with connection part near the end face of paxilla 1.2, and said annular knurl 2 is arranged on this plane of inclination.
The surface friction drag that the right corner that has increased big cylinder 1.1 is set of annular knurl 2; When the outer cover 3 that is used to cover big cylinder 1.1 is sleeved on 1.1 last times of big cylinder; The crimping 3.1 of outer cover 3 is fitted relatively firmly with the right corner of big cylinder 1.1; Like this outer cover 3 just suit must compare surely, obscission be difficult for to take place.
