Abstract
The utility model relates to a generator with a planetary gear, which comprises a shell, a stator, a rotor, a rotor shaft and a pulley. The stator and the rotor are arranged in the shell, and the rotor is arranged on the rotor shaft. The generator is characterized in that a planetary gear speeder which consists of a geared ring, a geared ring seat, a planetary wheel and a planetary wheel shaft is arranged between the pulley and the rotor shaft; the geared ring is fixedly arranged on the geared ring seat; the planetary wheel shaft is arranged on the geared ring through a bearing; the planetary wheel is engaged with the geared ring and is arranged on the planetary wheel shaft through a stub shaft; the end of the rotor shaft is provided with a gear which is engaged with the planetary wheel; and the pulley is arranged on the planetary wheel shaft to drive the planetary wheel shaft to rotate and drive the rotor shaft to rotate through the planetary wheel. The utility model has the following advantages of increasing the transmission ratio between the engine and the generator rotor, speeding up the rotation of the generator rotor, improving the generating capability of the generator with the low speed of the engine, and reducing the manufacturing cost of the generator under the condition without changing the size of the pulley.
Description
Technical field
The utility model belongs to a kind of generator, particularly a kind ofly has a planetary generator.
Background technology
At present, the drive mechanism of alternator for vehicle all adopts belt pulley to drive armature spindle and directly drives, and promptly armature spindle is an axis, and belt pulley is installed on the armature spindle, directly drives the armature spindle rotation.The shortcoming of this structure is, owing to will protect belt, the gearratio of belt pulley and main shaft is restricted usually, and therefore, gearratio is less, and when engine speed was hanged down, the energy output of generator was little.If when low engine speed, improve the energy output of generator, then need to increase the size of generator unit stator and rotor, increase the number of turn of generator unit stator winding, overall dimensions and weight that this has not only increased generator have also increased the manufacturing cost of generator.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above that existing alternator for vehicle exists, provide a kind of when low engine speed energy output big have a planetary generator.
The utility model comprises shell, stator, rotor, armature spindle and belt pulley, stator and rotor are installed in the enclosure, rotor is installed on the armature spindle, its special character is, the planetary gear speeder is installed between belt pulley and armature spindle, described planetary gear speeder is by gear ring, gear ring base, planetary gear and planet wheel spindle constitute, gear ring is fixed on the gear ring base, planet wheel spindle by Bearing Installation on gear ring base, planetary gear is meshed with gear ring, and is installed on the planet wheel spindle by minor axis, and the end of described armature spindle is a gear, and be meshed with planetary gear, belt pulley is installed on the planet wheel spindle, drives the planet wheel spindle rotation, and drives the armature spindle rotation by planetary gear, improve the rotating speed of armature spindle, increase the gearratio between engine and the generator.
Advantage of the present utility model is, the planetary gear speeder is installed between belt pulley and armature spindle, under the situation of belt pulley size constancy, increase the gearratio between engine and the generator amature, accelerated the rotary speed of generator amature, improved the energy output of generator when low engine speed, simultaneously, can reduce the effective radius and the effective length of generator stator and rotor, reduce the number of turn of stator coil, reduce the manufacturing cost of generator.
