Description

DC generator carries generating energy-storage device

The utility model relates to motor device, and a kind of specifically motor carries generating energy-storage device.

DC motor is widely used in the every field of social production at present, but find in actual use, the load of DC motor often changes, sometimes load just in time is the nominal load of motor, i.e. load matched, at this moment, motor normally moves, and the electric energy that power supply is supplied with all is converted to mechanical energy, and is exported by the main shaft of motor, and when underloading, motor speed raises, and actual speed surpasses rated speed, because power supply provides power not change, therefore, at this moment motor only is converted to mechanical energy with a part of electric energy, and all the other energy have partly all consumed because of the self-heating and the frictional resistance of motor, so, when being operated in underloading, not only wasted a large amount of electric energy, efficient is low, and the serviceability of the long-time warming-up effect motor of motor.

The purpose of this utility model is to provide a kind of motor to carry generating energy-storage device, at the motor full load, it can convert electric energy to mechanical energy, and when motor underloading or zero load, by the centrifugal clutch transmitting torque, the rotation of drive generator is converted to electric energy with unnecessary mechanical energy and is stored in the storage battery, thereby reaches the order of energy savings.

The purpose of this utility model is achieved in that

A kind of DC motor carries generating energy-storage device, includes casing, motor rotor, stator, generator amature, stator, storage battery, it is characterized in that:

The rotor of motor is made of the iron core and the iron core winding that are contained on the main shaft, this main shaft is contained in the bearing pedestal of front end housing and center bearing bracket, motor stator is made of two blocks of different permanent magnets of magnetic that are packed on the casing inner wall, and the iron core winding of motor is connected with the storage battery power supply utmost point by a commutator;

The rotor of generator is made of the iron core and the iron core winding that are contained in the rotating shaft, this rotating shaft is contained in the bearing pedestal of rear end cap and center bearing bracket, the stator of generator is made of the other two blocks of different permanent magnets of magnetic that are packed on the casing inner wall, and generator iron core winding is connected with the charging utmost point of storage battery by a commutator;

The main shaft of described motor is concentric with the rotating shaft of described generator, and this diaxon connects by a centrifugal clutch.

The utility model compared with prior art has following positive beneficial effect:

1, adopt clutch to control being connected of motor main shaft and generator shaft, therefore can be implemented in motor speed when fast, that is during underloading, by clutch from the generator shaft that is dynamically connected, and at the motor full load, that is rotating speed is when slow, and clutch is inoperative, at this moment, motor main shaft is not connected with generator shaft, when having realized the motor underloading, generator work is to charge in batteries, full load, generator is not worked, and electric energy is all supplied with motor, thereby reaches the purpose of energy savings.

2, motor stator of this product and generator unit stator constitute by the permanent magnet that is installed in the casing, with storage battery when motor or the generator powered, only need rotor is powered, do not need stator is powered, thereby the amount of power supply that can save storage battery relatively, this can prolong the service time of storage battery to for example very big benefit being arranged during field work away from power supply.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is the utility model one example structure cutaway view;

Fig. 2 is a clutch partial enlarged drawing among Fig. 1;

Fig. 3 be among Fig. 2 along A-A line cutaway view.

Referring to Fig. 1, center bearing bracket 2,3 is installed in the casing 1, be separately installed with bearing 21,31 on the center bearing bracket 2 and 3, be separately installed with bearing 41,51 on front end housing 4, the rear end cap 5, the main shaft 6 of motor is installed in the bearing 21,41.Iron core of rotor of motor 61 is installed on the motor main shaft 6, rotor winding 62 is installed on the iron core 61, on the inwall of casing 1 with rotor core 61 corresponding positions on, pair of permanent magnets 8,9 is installed, the magnetic of magnet 8,9 is different, rotor winding 62 is connected with commutator 63, and commutator 63 links to each other with carbon brush 64,65, and carbon brush 64,65 is connected with feeder ear positive pole, the negative pole of storage battery 13 with lead respectively.

Alternator shaft 7 is installed in the bearing 31,51, generator rotor core 71 is installed on the alternator shaft 7, iron core 71 is equipped with rotor winding 72, on the inwall of casing 1 with on the rotor core 71 corresponding positions pair of permanent magnets 10,11 is installed, the magnetic of magnet 10,11 is different, rotor winding 72 is connected with commutator 73, and commutator 73 links to each other with carbon brush 74,75, and carbon brush 74,75 is connected with positive pole, the negative pole of storage battery 13 charging ends with lead respectively.

Motor main shaft 6 and alternator shaft 7 concentrics, and main shaft 6 is connected by centrifugal clutch 12 with rotating shaft 7.

Referring to Fig. 2, Fig. 3, the axle sleeve 121 of clutch 12 is connected with motor main shaft 6, the drum 122 of clutch 12 is connected with the motor-driven rotating shaft 7 of generating, when motor main shaft 6 rotating speeds change low, tile fragment 123 does not contact with drum 122, drum 122 does not rotate, alternator shaft 7 does not rotate, when main shaft 6 rotating speeds reach a certain definite value, when centrifugal force surpassed spring force, tile fragment 123 suffered centrifugal force made flat spring 124 produce enough big distortion and produce bigger pressure, make the enough big frictional force of generation between tile fragment 123 and the drum 122, tile fragment 123 just begins progressively to engage transfer torque with drum 122, the rotation of main shaft 6 just drives alternator shaft 7 by centrifugal clutch 12 and rotates generating like this, thereby has realized the motor full load, when promptly rotating speed is low, clutch is transmitting torque not, and generator does not rotate.Motor underloading or when unloaded, motor main shaft 6 rotating speed height under centrifugal action, make that centrifugal clutch axle sleeve and drum are automatic to be combined, thereby alternator shaft 7 are driven, and realizes the purpose of generating electricity.
