Abstract
The utility model relates to a planetary gear reducing motor with plane rotation output and small teeth difference, the utility model is characterized in that: an outer rotor eccentric outer shell of an outer rotor motor is taken as an eccentric wheel of a planetary gear with small teeth difference, a pin shaft which transmits the rotation of the planetary gear and a central core shaft for rotation positioning are arranged on an output disk. The utility model is used for driving a table surface of a dinning table, which can be arranged at the center of the dinning table; the drive torque is big, the drive effect is good and the usage is convenient.
Description
Affiliated technical field
The utility model relates to a kind of plane and rotates output small teeth number difference planet gear reducing motor, and this reducing motor can be used as the electric driving mechanism on the motor-driven dining table.
Background technology
Distance is less between the table top of existing dining table and the desktop, conventional between 30-40mm, between so little distance, place the drive motors of Dining table top,, require drive motors that the torque of tens of ox rice is provided under the rotating speed that the per minute number changes having relatively high expectations of drive motors.
At present, domestic most of Dining table top promotes by artificial, and the part motor-driven dining table adopts turning motor, is placed on the middle driving of dining table, and moment is less.Up to the present, also desirable without comparison motor-driven dining table drive unit.
Summary of the invention
The utility model proposes a kind of simple in structurely, output small teeth number difference planet gear reducing motor solution is rotated on the flat plane of thinner thickness.
Output small teeth number difference planet gear reducing motor is rotated on plane of the present utility model, its technical scheme comprises the external rotor electric machine and the small teeth number difference planet gear reducing gear of eccentric shell, architectural feature is: the eccentric shell of the external rotor of external rotor electric machine is provided with the bearing pin of transmission planetary gear rotation and the central mandrel of rotational positioning as the eccentric wheel of small teeth number difference planet gear on the output panel.
Employing has the external rotor claw-pole motor of eccentric shell or the external rotor electric machine with eccentric shell of other types, and the internal stator of motor produces rotating magnetic field, drives the external rotor rotation, and the external rotor of eccentric profile is as the off-centre input of small teeth number difference planet gear.The external rotor outside is placed with rolling bearing, and planetary gear is placed in the rolling bearing outside, the internal-round gear wheel engagement of planetary gear and fixed disk.The internal-round gear number of fixed disk is greater than number of teeth 1-4 tooth of planetary gear, when the eccentric shell of external rotor electric machine rotates, and planet crop rotation planetary motion, thus realize deceleration transmission.Output panel connects the rotation of transmitting planetary gear by the pivot pin structure, rotates by the location of the central mandrel on the output panel.
The utility model proposes plane rotation output small teeth number difference planet gear reducing motor and drive Dining table top, it is in the centre-driven of table, and driving moment is big, drives effective.The plane is rotated output small teeth number difference planet gear reducing motor and can directly be placed between existing dining table and the table top, and is easy to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that output small teeth number difference planet gear reducing motor structure chart is rotated on the utility model plane.
Fig. 2 is that rotate among output small teeth number difference planet gear reducing motor section of structure Fig. 1 on the utility model plane
1. ball, 2. output panel, 3. planetary gear is 4. gone up sliding bearing, 5. rolling bearing, 6. magnet steel, 7. coil, 8. fixed disk, 9. rubber washer, 10. card, 11. sliding bearing, the 12. claw-pole motor dewclaw utmost points, the 13. claw-pole motor lower claw utmost points, 14. eccentric shells, 15. properties of journal bearing lubricated.
Embodiment
The internal stator that the dewclaw utmost point 12 lower claw utmost points 13 of claw-pole motor and coil 7 are assembled into claw-pole motor tightly fits on the fixed disk 8.The eccentric shell 14 of external rotor and magnet steel 6 are formed the external rotor parts, by last sliding bearing 4 and properties of journal bearing lubricated 15 location.During the coil indirect current, external rotor rotates.The external rotor outside is placed with rolling bearing 5, and planetary gear 3 is placed in rolling bearing 5 outsides, and planetary gear 3 meshes with the internal-round gear wheel of fixed disk 8.The number of teeth of planetary gear 3 is less than the number of teeth of the internal-round gear wheel on the fixed disk 8, and when the eccentric shell 14 of external rotor electric machine rotated, the planetary gear 3 of small teeth number difference planet gear was done planetary motion, thereby realized deceleration transmission.
Output panel 2 connects the rotation of transmitting small teeth number difference planet gear 3 by the pivot pin structure, and a part of action of gravity of Dining table top produces frictional force on rubber washer 9 time between output panel and Dining table top, drive the Dining table top rotation.
Speed reducing ratio is relevant with the number of teeth difference of planetary gear 3 and fixed disk 8 internal-round gears wheel, and the number of teeth of the internal-round gear wheel of general fixed disk 8 is greater than number of teeth 1-4 tooth of planetary gear 3.
