Description

Planetary motor

Technical field:

The utility model relates to the motor technology field, particularly planetary motor.

Background technology:

In the daily life and in the production practices, a lot of fields all need to use motor, and the kind of motor is also very wide.The rotation of motor when work rotor, thus power provided for external equipment.Existing motor all is to be changed and driven the rotor rotation by electricity, magnetic mostly, and the rotating speed of rotor is subjected to bigger restriction, thereby also is restricted to the torsion that external equipment provided; These motor applications are when automobile engine systems, and efficient is very low, do not satisfy and put into practice needs; And in order to obtain bigger actuating force, generally be to adopt the bigger motor of power, also increased the consumption of the energy accordingly.In order to respond country about the call of energy-saving and emission-reduction, the operating efficiency of raising motor, the applicant make a big improvement on the basis of existing motor.

The utility model content:

The purpose of this utility model is to provide planetary motor at the deficiencies in the prior art, and it can provide bigger rotating speed and bigger torsion, and operating efficiency is higher and have an advantage of saving the energy.

For achieving the above object, the utility model adopts following technical scheme:

It comprises stator casing, rotation axis, rotor, circular commutator, brush carriage, rotor is positioned at stator casing and is sheathed on the rotation axis, rotor comprises preceding rotor field spider, back rotor field spider, a plurality of motor, and motor is parallel to rotation axis and is installed between the forward and backward rotor field spider; Planetary gears is installed in the stator casing, and planetary gears comprises bull gear, a plurality of star gear train, and the rotating shaft of motor is all fixedlyed connected with star gear train.

Have the concentric copper ring of three separation on the described circular commutator, copper ring has Wiring port respectively.

Have three the concentric copper rings that separate corresponding with circular commutator on the described brush carriage, copper ring has power interface respectively, is folded with a plurality of carbon brush respectively between the copper ring of brush carriage and the copper ring of circular commutator.

The beneficial effects of the utility model are, rotor adopts a plurality of motors, cooperate planetary gears simultaneously, during each machine operation, make the rotor rotation by planetary gears, can improve the rotating speed of rotor and improve the torsion of rotation axis, can dress up with other generating sets and be automotive engine system, can reach the effect that operating efficiency is higher and save the energy at industrial production, traffic and transport field.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described.

See accompanying drawing 1-6, the utility model comprises: stator casing 1, rotation axis 2, rotor, circular commutator 13, brush carriage 14, the rear and front end of stator casing 1 is separately installed with protecgulum 5, back inner cap 6, back enclosing cover 7, clutch shaft bearing 8 is installed on the protecgulum 5, second bearing 9 is installed on the back inner cap 6, rotation axis 2 is through on clutch shaft bearing 8, second bearing 9, and the output of rotation axis 2 is positioned at stator casing 1 outside; Rotor and is sheathed on the rotation axis 2 in stator casing 1, between protecgulum 5 and the back inner cap 6, and rotor comprises preceding rotor field spider 10, afterwards rotor field spider 11, a plurality of motor 3, and motor is parallel to rotation axis 2 and is installed between the forward and backward

rotor field spider

10,11; In the stator casing 1 planetary gears is installed, planetary gears comprises bull gear, a plurality of star gear train 4, and as shown in FIG., stator casing 1 inboard forms tooth and constitutes bull gear, and the rotating shaft of motor 3 is all fixedlyed connected with star gear train 4.

Operation principle of the present utility model is, rotor adopts two above motors 3, and during each motor 3 work, the rotating shaft of motor 3 is rotated, and rotates thereby drive star gear train 4, thereby rotatory force is concentrated to rotation axis 2, produces the torsion more than 2 times; In addition, under the influence of each motor 3 self gravitation, produce very big inertia when motor 3 runs up, therefore, when improving rotating speed, also improved the torsion of rotation axis 2 outputs.

After the utility model and the assembling of small-sized fuel electric generator, can become an automotive engine system, be applied to industrial production, traffic and transport field, can reach the effect that operating efficiency is higher and save the energy; For example, when being applied on the lorry, can adopt a plurality of the utility model motor to form a big planetary motor mechanism, can increase the strength of engine, satisfy the requirement that climbing capacity is strong and loading is many.

Have the concentric copper ring 12 of three separation on the described circular commutator 13, copper ring 12 has Wiring port 20 respectively; Have three the concentric copper rings 19 that separate corresponding with circular commutator 13 on the described brush carriage 14, copper ring 19 has power interface 21 respectively, is folded with a plurality of carbon brush 18 respectively between the copper ring 19 of brush carriage 14 and the copper ring 12 of circular commutator 13; Terminal box 15 also is installed on the stator casing 1, and power line 16 is connected to the power interface 21 of brush carriage 14, and the power line 17 of motor 3 is connected to the Wiring port 20 on the circular commutator 13; Circular commutator 13 of the present utility model, brush carriage 14 adopt said structure, when the rotor rotary work, can guarantee the intact contact of circuit, guarantee the motor job stability.

The utlity model has the advantage that operating efficiency is higher and save the energy.
