Description of the drawings
Fig. 1 is the utility model drive assembly main cross-sectional schematic diagram；
Fig. 2 is that the utility model magneto connect partial schematic diagram with speed reducer spline.
Specific embodiment
As shown in Figure 1, the built-in frequency control drive assembly of the utility model crane, including reel 5, sets in reel 5
There is rare-earth permanent-magnet electric machine 4, as shown in Fig. 2, the output shaft end of rare-earth permanent-magnet electric machine 4 is equipped with spline 10 and cantilevered star speed reducer
6 are connected, and are connected using spline, improve connection accuracy, and the power output for making rare-earth permanent-magnet electric machine 4 is more stable.Select cantilevered star
Shape speed reducer 6 is connected with rare-earth permanent-magnet electric machine 4, is to reduce speed reducer volume, mitigates the overall weight of carrying reel 5, and
And more former parallel axle speed reducing machine is energy saving.
As shown in Figure 1, the output terminal of cantilevered star speed reducer 6, which is set on 5 inner wall of reel, transmission support part 7, rare earth is forever
The input terminal of magneto 4 is additionally provided with axis of a cylinder and holds 3, and axis of a cylinder holds 3 and is respectively arranged on the both ends of reel 5, support transmission with transmission support part 7
Axis limits shaft run-out, increases transmission stability and improves the precision that drive shaft cartridge matches concentricity, dynamic torque is transmitted
To reel 5, band movable reel 5 rotates, so as to hoisting heavy.
The output shaft end of 5 outer end cantilevered star speed reducer 6 of reel is additionally provided with bearing block freight weight limit device 8 and limit switch 9,
Realize load capacity limitation and the limitation of lifting position when carrying reel 5 is run.Brake 1 and 4 input terminal of rare-earth permanent-magnet electric machine
It is connected, 1 external hanging type of brake facilitates brake control operations, securely and reliably.The Design of Rotation of the rare-earth permanent-magnet electric machine 4 is
200r/min improves motor shaft torque density, and motor input shaft realizes control for brake, is run with the slow-speed of revolution and improves the operation longevity
Life.
The input terminal of rare-earth permanent-magnet electric machine 4 and the output terminal of limit switch 9 are connected respectively with variable frequency regulating speed control cabinet 2, become
Frequency converter is equipped in frequency timing control cabinet 2, with frequent starting, can realize the intelligent control of crane, operation is more flexible.Rare earth is forever
Magneto 4 employs soft start, reduces impact, realize low vibration, low noise working environment.Low-speed big Permanent Magnet and Electric
Machine 4 and 6 partial installation of cantilevered star speed reducer, facilitate maintaining.Through on-site measurement, low-speed big magneto 4
More former threephase asynchronous is energy saving between 16-25%, and it is energy saving that cantilevered star speed reducer 6 is driven more former parallel axle speed reducing machine
Between 3-5%, it is parallel that existing low-speed big magneto 4 adds 6 assembly of cantilevered star speed reducer to add with former threephase asynchronous
Axis speed reducer assembly compares, and total energy-saving is more than 20%, obvious economic.
