The front end of the armature shaft is provided with a driving gear which is meshed with the transmission gear. The isolator had an outer diameter of 36 mm and a weight of 242 g. Because the size of the isolator is small, the weight is small, the rotational inertia is small, and therefore the meshing of the driving gear and the flywheel is often unstable during starting, and the starting reliability is poor. In addition, when above-mentioned gasoline engine was used for the outdoor operations, often accompanied sleet during, sleet can get into inside through the breach of transmission casing, leads to the isolator to freeze the card stagnation and can not get rid of, influences normal start. Meanwhile, rain and snow entering the transmission shell can cause poor lubrication inside the isolator, so that the service life and the working reliability of the isolator are directly influenced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a starter motor, this starter motor not only starts good reliability, long service life moreover.
In order to solve the technical problem, the utility model relates to a starting motor, which comprises a motor, drive gear and isolator, the motor includes the casing, stator assembly and rotor assembly, rotor assembly includes the armature shaft, the casing includes front end housing and rear end cap, the front end portion of armature shaft wears to adorn on the front end cap, the rear end portion of armature shaft is located the rear end cap, drive gear sets up on the rear end portion of transmission shaft, the front and back both ends of transmission shaft set up respectively on the front end and the rear end of transmission casing, the rear end of transmission casing sets up on the front end cap of casing, the isolator suit is on the transmission shaft, drive gear suit is on the transmission shaft, and drive gear sets up on the isolator, the cover is equipped with the spring on the transmission shaft, this spring is located the front end portion of transmission shaft, the front end of armature shaft is equipped with the driving gear, this; the isolator has an outer diameter of 42 to 47 millimeters and a weight of 380 to 460 grams; and a drain hole is formed in the lower part of the transmission shell.
The lower part of the transmission shell is provided with a drain hole which is positioned at the lowest part of the transmission shell.
The front end cover of the machine shell is provided with heat dissipation holes.
In the above-described starter motor, since the outer diameter of the isolator is increased to 42 to 47 mm and the weight is increased to 380 to 460 g, the rotational inertia is large as compared with the prior art, and therefore the isolator enables the driving gear to be engaged with the flywheel better at the time of starting, and the starting reliability is good. The lower part of the transmission shell is provided with the drain hole, so that rain, snow and water entering the transmission shell can be drained through the drain hole in time, and the defects that in the prior art, the lubrication inside the isolator is poor due to the fact that the rain and snow enter the transmission shell, the service life of the isolator is affected, and the working reliability of the isolator is affected are overcome, and therefore the starting motor isolator is long in service life and good in working reliability.

FIG. 2 is a schematic view of the connection structure of the transmission gear, the driving gear, the isolator and the transmission gear.
Detailed Description
In fig. 1 and 2, a starter motor includes a motor, a transmission gear, a drive gear 5, and a one-way clutch. The motor comprises a shell, a stator assembly and a rotor assembly. The rotor assembly includes an armature shaft. The housing comprises a front cover 3 and a rear cover 1. The front end of the armature shaft is inserted into the front cover 3, and the rear end of the armature shaft is located in the rear cover 1. The transmission gear 7 is arranged on the rear end part of the transmission shaft 9, and the front end and the rear end of the transmission shaft 9 are respectively arranged on the front end and the rear end of the transmission shell 4. The rear end of the transmission housing 4 is arranged on the front end cover 3 of the machine shell. The isolator 8 is sleeved on the transmission shaft 9, the driving gear 5 is sleeved on the transmission shaft 9, and the driving gear 5 is arranged on the isolator 8. The transmission shaft 9 is sleeved with a spring which is positioned at the front end part of the transmission shaft 9. The front end of the armature shaft is provided with a driving gear which is engaged with the transmission gear 7; the isolator 8 has an outer diameter of 42 to 47 mm and a weight of 380 to 460 g. The lower part of the transmission shell 4 is provided with a water drainage hole 6.
